Edward Glaeser of Harvard University and author of The Triumph of Cities talks with EconTalk host Russ Roberts about American cities. The conversation begins with a discussion of the history of Detroit over the last century and its current plight. What might be done to improve Detroit's situation? Why are other cities experiencing similar challenges to those facing Detroit? Why are some cities thriving and growing? What policies might help ailing cities and what policies have helped those cities that succeed? The conversation concludes with a discussion of why cities have such potential for growth.

0:33Intro. [Recording date: April 15, 2013.] Russ: Topic is cities; start with recent post you had at the New York Times's blog, Economix, on Detroit. Give us a brief history of that city. It's not doing well right now, but it wasn't always that way, was it? Guest: No. If you look back 120 years ago or so, Detroit looked like one of the most entrepreneurial places on the planet. It seemed as if there was an automotive genius on every street corner. If you look back 60 years ago, Detroit was among the most productive places on the planet, with the companies that were formed by those automotive geniuses coming to fruition and producing cars that were the technological wonder of the world. So, Detroit's decline is of more recent heritage, of the past 50 years. And it's an incredible story, an incredible tragedy. And it tells us a great deal about the way that cities work and the way that local economies function. Russ: So, what went wrong? Guest: If we go back to those small-scale entrepreneurs of 120 years ago--it's not just Henry Ford; it's the Dodge brothers, the Fisher brothers, David Dunbar Buick, Billy Durant nearby Flint--all of these men were trying to figure out how to solve this technological problem, making the automobile cost effective, produce cheap, solid cars for ordinary people to run in the world. They managed to do that, Ford above all, by taking advantage of each other's ideas, each other supplies, financing that was collaboratively arranged. And together they were able to achieve this remarkable technological feat. The problem was the big idea was a vast, vertically integrated factory. And that's a great recipe for short run productivity, but a really bad recipe for long run reinvention. And a bad recipe for urban areas more generally, because once you've got a River Rouge plant, once you've got this mass vertically integrated factory, it doesn't need the city; it doesn't give to the city. It's very, very productive but you could move it outside the city, as indeed Ford did when he moved his plant from the central city of Detroit to River Rouge. And then of course once you are at this stage of the technology of an industry, you can move those plants to wherever it is that cost minimization dictates you should go. And that's of course exactly what happens. Jobs first suburbanized, then moved to lower cost areas. The work of Tom Holmes at the U. of Minnesota shows how remarkable the difference is in state policies towards unions, labor, how powerful those policies were in explaining industrial growth after 1947. And of course it globalizes. It leaves cities altogether. And that's exactly what happened in automobiles. In some sense--and what was left was relatively little, because it's a sort of inversion[?] of the natural resource curse, because it was precisely because Detroit had these incredibly productive machines that they squeezed out all other sources of invention--rather than having lots of small entrepreneurs you had middle managers for General Motors (GM) and Ford. And those guys were not going to be particularly adept at figuring out some new industry and new activity when the automobile production moved elsewhere or declined. And that's at least how I think about this--that successful cities today are marked by small firms, smart people, and connections to the outside world. And that was what Detroit was about in 1890 but it's not what Detroit was about in 1970. And I think that sowed the seeds of decline.
4:25Russ: So, one way to describe what you are saying is in the early part of the 20th century, Detroit was something like Silicon Valley, a hub of creative talent, a lot of complementarity between the ideas and the supply chain and interactions between those people that all came together. Lots of competition, which encouraged people to try harder and innovate, or do the best they could. Are you suggesting then that Silicon Valley is prone to this kind of change at some point? If the computer were to become less important somewhere down the road or produced in a different way? Guest: The question is to what extent do the Silicon Valley firms become dominated by very strong returns to scale, a few dominant firms capitalize on it. I think it's built into the genes of every industry that they will eventually decline. The question is whether or not the region then reinvents itself. And there are two things that enable particular regions to reinvent themselves. One is skills, measured education, human capital. The year, the share or the fraction in the metropolitan area with a college degree as of 1940 or 1960 or 1970 has been a very good predictor of whether, particularly northeastern or northwestern metropolitan areas, have been able to turn themselves around. And a particular form of human capital, entrepreneurial human capital, also seems to be critical, despite the fact that our proxies for entrepreneurial talent are relatively weak. We typically use things like the number of establishments per worker in a given area, or the share of employment in startups from some initial time period. Those weak proxies are still very, very strong predictors of urban regeneration, places that have lots of little firms have managed to do much better than places that were dominated by a few large firms, particularly if they are in a single industry. So, let's think for a second about Silicon Valley. Silicon Valley has lots of skilled workers. That's good. But what I don't know is whether Silicon Valley is going to look like it's dominated by a few large firms, Google playing the role of General Motors. Or whether or not it will continue to have lots of little startups. There's nothing wrong with big firms in terms of productivity. But they tend to train middle managers, not entrepreneurs. So that's, I think the other thing to look for. And one of the things that we have seen historically is that those little entrepreneurs are pretty good at switching industries when they need to. Think about New York, which, the dominated industry in New York was garment manufacturing. It was a large industrial cluster in the 1950s than automobile production was. But those small scale people who led those garment firms, they were pretty adept at doing something else when the industry jettisoned hundreds of thousands of jobs in the 1960s. No way that the middle managers for U.S. Steel or General Motors were not. Russ: So, I want to stick with this general issue for a minute and then we'll come back to Detroit. But I've heard this before that the way that a city thrives--it's become to me a bizarre policy cliche--you need lots of college graduates. As if somehow that's a magic wand. And, number one, it doesn't seem like a guaranteed magic wand. And number two, we don't know anything really about why college graduates like to live in particular cities. If you are Iowa City--that's a bad example. Let me pick Biloxi, Mississippi or Wichita, Kansas that don't have as many college graduates as, say, Raleigh Durham or the Silicon Valley, and you are the mayor of one of those towns, of which there are millions, and you are told: Oh, we know how to make the town do better. We just need more college graduates. So what's the policy implication of that for the mayor? Guest: Well, it's only slightly more helpful than reminding the mayors of the power of January temperature in predicting areas' success, which is an even more useless fact that I'm prone to remind people of. You are right. There are relatively limited things, certainly in the short run, that you can do about it. I tend to think that this just pushes you back toward the basics of good city government, that college graduates are not fundamentally different in the sense that they care about good schools and decent commutes and safe streets. I do think there is a little bit of bite in it, though, when you think about local redistribution. So, I think there are lots of reasons why we should be wary of localities trying to run their own social safety nets, the ease of exit for companies and for richer people. But if you are focused on the incredible importance of people at the high end of the human capital distribution, I think that makes you even warier of trying to do the sort of thing that Detroit did after 1970 of having sort of very aggressive social policies that weren't particularly attractive to people with high levels of human capital. That's why I think this has some policy bite, although it's certainly not as if you can just turn on a dial and all of a sudden your share of college graduates increases from 10 to 40%. Russ: It's easy--you just need a lot of hip places and cool coffee shops. Guest: That's right. Russ: I've remarked on this program before that one of the stranger policy secrets that used to be popular when I was in St. Louis was farmer's markets. Because college people like farmer's markets. So if we have farmers' markets we'll do better. And those kind of magic wands I don't think do very well. Guest: Yeah, I think that's probably right. Russ: Not that there's anything wrong with a farmers' market. I like them myself. Guest: No, actually compared to other things localities do, they tend to be fairly cheap. It's not as if things are likely to be magical. We do know in terms of the causal chain of that stuff, if one believes Enrico Moretti's work on this, the national policy to establish land grant colleges in particular places does appear to have had lasting effects. Now that's not a cost-benefit analysis of land grant colleges. That just says that those places that had land grant colleges prior to 1940 have had a very good thirty years after 1980. But I don't know what that means for a mayor, given that they don't particularly have the ability to establish a land grant college or even any sort of technical university, unless of course you are Michael Bloomberg and you are going to plop one down in the middle of the East River. Russ: But one of the obvious again apparent-to-the-eye kind of correlations that people do see is the synergies between great universities and innovation in an entrepreneurial environment. Again, I think cities, probably incorrectly, have decided that therefore they need to have a lot of incubators, places where smart young academics can help them start companies. Not that, unfortunately, some cities aren't very good at helping that. But they think that's got to be a good, again a way to get there from here. Or to try to make their schools, their universities better, as if there were an easy way to do that. I think obviously that's a very difficult thing to do. Guest: Right. I think that's absolutely right. You get to more sensible local policy implications when you sort of stick with the things that local localities are already doing and you ask how to make them more friendly to this. So, one thing, if you thought that the spillover from local universities were powerful--indeed, I think there's a fair amount of evidence supporting that--you want to make sure that your land use regulations or spaces close to those universities are relatively friendly for building new relevant space. So it's not an issue of subsidies for these areas, but it's an issue of making sure you haven't zoned it off for single family detached houses in a way that enables no one to take advantage of that. So I think that feels a little more sensible. Boston is in the midst of this thing called the Innovation District--a former industrial land downtown on the waterfront in fact--and I'm relatively positive about this thing. It's not involving a huge amount of state subsidy. It's relatively prime real estate. You could--it's not hard to get people willing to build on this. But I think from a political point of view it's easier to justify zoning for commercial industrial mixed view space when it's sort of wrapped with the magic of startups. So, I don't have any problem with localities if they want to justify sensible things by saying it's about tech clusters. But spending a fair amount of money to try to create an artificial cluster does feel like a very dangerous thing. And certainly the work of Josh Lerner, whose fine book Boulevard of Broken Dreams reminds us of how difficult it is for localities to actually do this. There are far more failures than successes.
13:02Russ: So, let's go back to Detroit. What's your diagnosis of what went wrong there in particular? Guest: So, the seeds of the industrial decline were I think set in this very large firm-intensive industrial monoculture that was very heavily invested in lower-skilled or at least less formally skilled workers. I think it's not that those Detroit workers weren't skilled, but they were skilled with very firm- and even task-specific skills that made them particularly bad at adjusting to new things. And then on top of that you had a number of unwise policies that tended to be very infrastructure- and construction-intensive. And I think this is part of want to think about in terms of what public policy does, particularly in declining cities. It is so natural and so attractive to plunk down a new skyscraper and declare Cleveland as 'come back.' Or to build a monorail and pretend you are going to be just as successful as Disneyworld, for some reason. You get short term headlines even when this infrastructure is just totally ill-suited for the actual needs of the city. The hallmark of declining cities is to have funded structures and infrastructure relative to the level of demand in that city. Like, Detroit, more than 90% of the homes in central-city Detroit are valued significantly less than construction costs. It never made sense for the federal government to subsidize the building of new housing there in the form of urban renewal. And it certainly made no sense after the Highway Aid Act of 1973 to spend hundreds of millions of dollars on a monorail that glides over often-empty streets. Easy to get around downtown Detroit. You didn't need a monorail to help. So, some infrastructure is certainly appropriate in growing places, and certainly if we were talking about the cities of India we would be talking about the need for better water, better electricity, better transit infrastructure. But not Detroit. And what I think Detroit really needed was better investment in its schools and its safety, rather than thinking that you were going to fix everything with a monorail. Russ: And the lesson--do you want to draw any lessons from that for the constant cry we hear of the need for more infrastructure spending? Do you think America's infrastructure is--I did a podcast with Robert Frank on this. He points out, as many have, I think it's the American Society of Engineers gives America's infrastructure a grade of D. I've suggested that maybe they aren't the best people to hand out the grades; they kind of have an incentive. Guest: Yeah, I have suggested such a thing as well. If the American Medical Association (AMA) argues for more health spending, do we think that they are completely disinterested in it? Russ: But do you think we have an infrastructure problem in the United States? Guest: I'm not an engineer, so I can't tell you about crumbling bridges. I think they do want some serious set of tools for avoiding safety risks and perhaps those are inadequate. But, two major points on this. When I think about America as a whole, I see an amazing amount of infrastructure. And it certainly doesn't appear to me that we are deeply lacking in infrastructure. That wouldn't have seemed to me to be America's primary lack. I worry about competitiveness over the next 50 years; I am far more concerned with the quality of our schools than the quality of our highways. And the second thing which I think is central is I see no reason; almost all infrastructure can be paid for by users rather than the general tax revenues. I just cannot possibly see why we think that the crumbling bridge is a job for taxpayers far away rather than the users of that bridge. Or our airports need to be paid for with general tax revenue rather than by the generally well-heeled customers of those airports. So, I am certainly willing to believe that there are particular points of infrastructure that need upgrading; but if they can't be upgraded with the fees on their own users then I'm going to be much more skeptical about the need to upgrade it. Adam Smith said this quite clearly, quite eloquently, 240 years ago, that the best way to avoid white elephant projects was to fund those projects with fees on the people who were actually going to use them. Those words remain true today. Russ: Of course, you make an exception for baseball stadiums, I'm sure. I think the obvious problem is that whatever the economics case is for allowing people far away to pay for your stuff, on the grounds that, say, well, someday they may come to your city--the problem is the political incentives there are rather destructive. Guest: Absolutely. And given current electronic tolling facility, if they come to our city they will pay for the roads by going on them and having their credit card charged to ride them. They don't need to pay for it if they are not actually using the roads.
17:59Russ: You mention that you are much more worried about our schools than our highways. I think that's a very good concern, and I share that. But my guess is that Detroit, in this period we are talking about where things didn't go so well, I'd say 1970 to the present, a mere 43-year bad run, during that time I suspect they spent a lot of money on schools. They just didn't spend it very well. Or they face problems that the amount of spending couldn't overcome. Guest: It's always the case. It's not the sheer dollars involved in most of American cities, it's the way those dollars are being spent. I think usually the best case for spending more is that it's the only way that we can get reforms is by giving something to the interest groups that need to be bought off. But if I think about Detroit, if I think about schools going forward, I would be very--I mean, I think they should have done this 30 years ago--very intensive on charter schools or other voucher-like experiments rather than thinking they should come from the public system. Russ: Is there anything going on like that now in Detroit? Guest: Yes. In fact there's a--there are a lot of charter schools going on. There's a particular philanthropist who is very invested in them. Last time I was in Detroit I visited a charter school that was in the old GM building, where Harley Earl designed so many of the glories of GM's heyday. It's tied to a school of industrial design that was a charter school that kids looked so full of hope; I of course asked for randomization and test scores and they weren't able to deliver that yet. But it was a very positive sign. And I was almost feeling good about this situation until the Principal started talking about how things would really take off when they got a light rail stop outside of their school. And I looked outside--the streets were empty. You could drive 60 miles an hour down the street, and no conceivable need for a light rail stop. But there's something in Detroit's DNA which makes it think what it really needs is transportation technology. Which is not at all what it needs. But the charter school movement is there; it just needs to be pushed harder. And I think the more troubled a school system is, the more the case is for going almost entirely private. Which I think would not be a crazy thing for Detroit to contemplate. Much as I think that privatization of public spaces, particularly really dysfunctional public spaces right now, is not crazy in the context of Detroit. Russ: Now there have been some very successful uses of, I don't know what you want to call it, private public partnerships. I note that Bryant Park in New York has been a very nice story of that kind of change. I don't know if it's representative of anything but it's a very nice story. Guest: Yes. Absolutely. Bryant Park is special. Russ: Now, this particular charter school you are talking about, the one devoted to industrial design--you say 'devoted to industrial design' or however you worded it-- Guest: It's tied to a grown-up school that does industrial design, quite successfully, for adults. So it has an institutional connection. But it's a broader--it's a normal school. Russ: But the point is, it's not a college prep school of the traditional kind, hoping to send kids off to first-rate universities to major in liberal arts. It's got a different focus. Guest: You know, a bit of both, I think. I don't think they're precluding that. It's not purely vocational tech. But it certainly has some ties to hard skills that are valuable as well. Russ: Do you think that kind of vocational approach is something we should be doing more of? Guest: I think we certainly should be open to it. One of the virtues of having more charter line system is we get more innovation in this system and we get more opportunity for experimentation on it. Certainly in many areas there is lots of popularity of schools that are getting particular skills; we certainly see this in the popularity of many private educational institutions that are delivering hard skills to people. I think that if you have a more competitive system in the public school system in Detroit you will naturally have the delivery of skills that are offering economic value for customers, ex post, for students, after school. It would be helpful for economists to provide information about which of these skills are more desirable. But I see a lot of hope in the direction. Russ: Do you think it's important that those kids at that charter school or at any other ones, whatever good schools there are in Detroit, that they stay in Detroit? Do we really care? We see Detroit has declined. One way to look at it is to say: Well, people vote with their feet; it's a terrible tragedy for the people who are still stuck there because there's not much opportunity. But the most talented ones will leave. They'll go improve other cities. Do we care about Detroit per se? Guest: It's not that we don't care about it. But our primary focus is on people in Detroit, whether or not they choose to live in Detroit or elsewhere. So, the important thing is that those kids are well-educated and find a brighter future wherever they find a brighter future. So, it's not particularly, I mean I'm not disturbed by a kid who moves from Detroit to Houston to find a great life there; and I think that's absolutely right. So, the spirit of your suggestion is quite reasonable to me. I think there are a couple of minor caveats that I'd like to put out there. One of which is: The way that we've structured local government is that we have mayors who are responsible for places[?]. So, I do think it is David Bing's [Detroit Mayor] job to make his city as functional and successful as it can be. Although part of being functional and successful is just educating his kids, not minding if they move elsewhere. In some sense, an analogy I like to make between cities and companies on this, and local and national policy. So, it certainly shouldn't be the business of the national government whether or not one company thrives or fails. We want good national policies, and then there are winners and losers. But it's the job of the Chief Executive Officer (CEO) of that company, to make sure that it thrives. I see that the relationship between cities and national policies being somewhat similar. If the federal government should be picking winners and losers in particular places, it shouldn't be trying to prop up declining cities or populations in particular areas. But when you are looking at David Bing's perspective, he needs to have a bit of a place-related perspective that focuses on his particular location, making it as healthy as it can be. Russ: And he's the Mayor of Detroit. Guest: He is the Mayor of Detroit. Russ: Former National Basketball Association (NBA) player, I remember his jumpshot well.
24:42Russ: Now one thought, which I think is probably the result of confirmation bias, but maybe not, but I have when I look at some declining cities--and I may be cherry-picking here, so help me out--is that in many of them, they have had long periods of sustained, one-party rule. The city of Detroit is an example. The city of St. Louis. The mayor always comes from the same political party. There is going to be inevitably an accretion of corruption, patronage, inertia. How important do you think political competition is, or the lack of it, in explaining some of these cities that have failed? Guest: So, I certainly believe in political competition, as much as I believe in competition elsewhere. I've never seen anything that was empirically compelling on this, and I immediately think of a counterexample, which was of course Boston, which of course has had one-party rule for half a century. And often not all that much competition within the city, but at the same time is-- Russ: Successful. Guest: Yeah. So, I don't think it's necessary. But certainly it must be helpful. And one of the things that is quite interesting about New York is despite the fact that on some national political spectrum it's a very democratic city, but over the last 80 years, 40 of them have had mayors who were at least first elected as Republican. LaGuardia, Lindsay, Bloomberg, Giuliani. Which tells you that there is considerably more competition in New York than in most of these places. In part that's just because of the large size and because people are interested in running this city. But for sure it's helpful. The one thing I know that there's hard data on is the work of Fernando Ferrero and Joe Djurko on the impact of party affiliation and what mayors do, and they have this nice regression discontinuity design that enables you to compare those cities where a Republican won with 51% of the votes to one in which a Democrat won with 51% of the votes. And what they find is very little difference in the center between the two parties. Which goes back to the old line that there's no Democratic or Republican way to clear out the trash. That one of salutary things about cities is that because they are involved in very tangible outputs, they tend not to be as ideological. And they tend to be more driven by delivering basic city services. Although certainly many cities fall down on that and assuredly competition is helpful in creating some pressure on that. Russ: So, if you were mayor of Detroit yourself--King of Detroit, I'd like think of, or maybe you have David Bing's ear, which maybe you do--what would you do? Give me a short term plan and a long term plan. Guest: As you know, Detroit is currently being more controlled by the data pointed financial officers who have power relative to Bing himself. But it's not really rocket science. If you think of it as an overall plan, I would have essentially a transition close to a complete charter school provision in terms of the education side. So I would move almost completely out of the public school education business, if I were Detroit. In terms of policing, I would be doing more in terms of borrowing from those cities that have had very successful turnarounds in the quality of their policing. So, I know for example there's a project going on where they are borrowing from New York's successes. Boston has also had a reasonably successful policing--so many cities have. I'm not a police tactics expert, but I'd certainly be borrowing from that. I would be trying to privatize as much of the dysfunctional space in the city as I possibly can. The city, its physical footprint is so large, that creates just a very, very hard cost equation. They have not been as aggressive at using eminent domain to level neighborhoods as say for example Flint has. I'm myself quite wary of the use of eminent domain; every part of me that fears the excessive use of the power of the state, fears eminent domain, although I'm willing to believe that there are occasions where it is necessary. In this case I think there's a better approach. Which the mayor is basically following, which is you are going to restrict the areas in which public services are available all for [?] aid to people who are outside those areas, and then either charge them for the incremental cost of city services if they are outside of it or basically not provide certain city services outside of these core areas. Russ: What kind of services? Guest: Well, let's say trash pickup or something like that. I don't know exactly how the system is operating in Detroit in terms of the full area. But you need to do something that says, makes people in their locations pay for the cost of their actions. And if it costs considerably more to have city services available elsewhere, you need to have some pressure on that pushing people to relocate to areas which are more compact. And once you've done that you can essentially think about whether you can sell off the space that remains; and sell off in a way that literally shrinking the physical footprint of the administration within the city, so that in some subarea you are essentially selling to some private developer who essentially makes a private town within that area. It's essentially free from city interference, free from city cost. So I would do more to shrink to greatness, of trying to make the city's physical footprint somewhat smaller, use more private competition the school side, and do more in terms of borrowing from other cities on police side.
30:54Russ: So you introduce that discussion by saying it's not rocket science. And yet I don't think there's any city, other than the third part about maybe giving up some land that's not very productive--is there any city doing anything remotely like this that's aggressively privatizing education and its other services? And some of its land? As a way to revitalize itself? And if not, it's either not rocket science or their something else involved. Like politics. Guest: Well, I tend toward the latter. You started by making me king, which I took as a fairly absolute level of power. So that's certainly part of it. New Orleans has probably been the poster child for very aggressive charterization in the wake of Hurricane Katrina, so that's where I'd look. This thing that Dan Gilbert is doing in downtown Detroit is an example of trying to privatize some of the space. Russ: What's he doing? Who is he? Guest: He's the entrepreneur, the chairman, of Quicken Loans. And he's a Detroit native. And he's purchasing a fair amount of downtown real estate in Detroit, trying to sort of rebuild some part of the central city, buy a lot of very high density space with skyscrapers available for a song in central city Detroit. There's a question as to whether or not this project will actually work. But as much of the city that can be gotten off of Mayor Bing's books, those will certainly make his financial problem less severe; and I'd like to see more innovation in terms of the public side of running Detroit. I think the main reason why you don't see more of this is indeed politics. And for a mayor to admit that his, that he can't manage part of the city is an admission of failure, I don't think it's an admission of failure that Mayor Bing should feel bad about making in that the reasons for the difficulty are not of his doing. But it's politically very hard to do that, obviously. The power of interested parties in education that preclude large scale charterization is enormous. And policing is also a fairly, can also be fairly political. It's notable that that's the area where Detroit has actually been most aggressive in actually doing exactly the same thing I would do in that situation. So maybe the politics are less difficult there. Russ: Do you have a feel for what proportion of Detroit's employment right now is public versus private? Guest: Well, we have county business patterns data on this. That would be Wayne County rather than Detroit proper. So, Wayne County includes Detroit. Between 1998 and 2010 the number of paid employees in Wayne County declined from 755,000 to 570,000. So that's really a massive difference. And the number of manufacturing employees, the traditional heart of the Detroit economy has literally declined by 50%, from about 120,000 to about 60,000. One of the areas that's still very, very robust, and this gives [?] public private, the issue is that health care and social assistance, an industry that is traditionally driven by public sector spending, that is now 100,000 employees out of Wayne County's total 568,000. Russ: That's large. You alluded a minute ago to this idea of making people pay for the services--you said it in a couple of different places and ways--that they use. What's your thought on urban sprawl generally? Do you think it's a problem? Have we subsidized the suburbs overly in a way that's been destructive? Guest: We probably should be doing more to make sure people pay for the social cost of their actions. I think it was always inevitable that America would rebuild itself around the automobile. I don't think the right answer is we should expect no sprawl. Or tiny amounts of sprawl. We should expect a lot of sprawl. I think we can have somewhat better policies. We come back again to think about highways. It's I think entirely appropriate that people should be paying for the costs of driving, including of course myself, both in terms of either using gas taxes or better yet using tolls to do that. And obviously when you have new development it should pay for the social cost of hooking up public services that are involved. I don't think that that would massively reduce the amount of building on the urban edge. I think the lure of the car and car-based living is very, very strong. Russ: People like grass. They like yards. Especially people with kids. So I think, obviously there are people who like to raise their kids in a city, but there's always I think going to be people who want to raise their kids in a less urban environment. Guest: Sure. When I think about urban policies more generally I tend to think about eliminating those policies which create bias in one way or another. And that the policies that are anti-urban are the transport policy. Which--and this particularly came together in the coalition that gave us the Highway Aid Act of 1973--it thought about that if you bundle together public transit spending with highway spending that that's somehow or other neutral on this. But highway spending really has a massive difference in the accessibility of far-flung area. There are huge differences created by running a highway down the area. So that really pulls people out. Whereas adding a people-mover to Detroit does virtually nothing. It's a very bad deal for cities. I think most cities would be better off to give up on the public transit aid from the federal government and just say: We'd similarly like to stop spending general tax revenue on highways. The situation has only gotten worse in the stimulus package and the recent transport bill of last year. We've really gone from a system where we expected drivers to pay for the bulk of the cost of their roads through gas taxes to a world in which we are much more comfortable using general tax revenues to do it. And it's hard not to think that that's a mistake, in many dimensions. The secondary bias I think is significant is the way that we handle housing policy in the country. Having a very pro-home ownership policy also means you have an anti-urban policy, because typically single family houses are owner-occupied whereas multi-family dwellings are rented; on average more than 85% of multi-family dwellings with 5 or more units are rented, exactly the same percentage holds for single-family occupancy being owner-occupied. So if you are going to have federal policy which both directly, through let's say the home ownership interest deduction, or indirectly, through Fannie Mae and Freddie Mac are going to subsidize owning, you are going to be stacking the deck against high rise houses. So I think there are many reasons why we'd like to reform our pro-ownership policies. But that's yet another reason for it. Guest: Now the last thing that artificially stacks the deck against cities is just the way our local education systems work. So, by your telling me you kids like to go tromping around in grass, that's great; my kids do that. I have no problem with parents making those choices. However, I grew up in the streets of Manhattan and that can also work perfectly well. The problem is that we've created such a strong schooling incentive for people to move out of those cities that have weak school systems. I think anything that we can do that tries to somewhat reduces those spacial, those schooling-related, which are fundamentally government-created incentives to suburbanize, that's probably a good thing. So, for example, if you could imagine moving to a region-wide charter/public school system where you could choose any school anywhere within the region to go to, whether it's public or charter, that would be a system that would largely break down the incentives to locate in a particular area. Of course, that's politically completely infeasible. But anything that makes schools less problematic in urban areas would be helpful. Russ: Yeah. The idea that if you want your kid to go to a good school, which strangely enough many parents care deeply about it, means that you have to live in the neighborhood of a good school, is--it's like saying, if you want to have a really good car you have to live near where it's made. It's a bizarre connection that we just take for granted now because it's been that way for so long. It clearly has a terrible impact on the poor, in particular; and of course, I think rich people don't just want to have lots of grass for their kids. They also want to have really good schools for their kids. And they also want, maybe want their kids to go to schools with kids like them, which could be part of the reason that's going to be a difficult thing politically to break. It really bothers me a lot. It's terrible. It's 'free.' Hey, free schooling. But unfortunately, if you want to live near a really good school you have to pay an enormous premium for your house. So it's not free. Terrible. Guest: Absolutely.
40:41Russ: Well, let's move away from Detroit to cheerier climes. A lot of cities are doing great today which weren't doing well before. What has changed? What are they doing right? What have we learned? Guest: I think most of the reason they are doing great has to do with economic changes, not necessarily with all that much that the cities themselves have done. Although the one thing that you would give cities like New York a great deal of credit for over the last 30 years is they have become dramatically safer. And that is really directly tied to a public service. Russ: Maybe. Maybe demographics. Guest: Tied. Tied. Russ: Fair enough. Guest: I have written papers arguing that our ability to explain changes in the crime rate are very, very limited. So I'm with you on this. But it certainly is tied to it. People should be able to give at least some credit to the New York Police Department (NYPD) and the Boston Police Department. So, the larger framework is, you go back to the 1970s. All of America's older cities were hit by the move to urban sprawl. All of these cities had grown great around transportation cost advantages that one time figured very, very largely in the growth of those cities. I think the railroads in Chicago or think of the harbor in New York City. Over the course of the 20th century those transportation cost advantages had largely been eliminated. And as a result, the older, manufacturing industries like New York's garment center that had once been the lynchpin of the local economy, those industries moved elsewhere. They disappeared. And as industry fled there was often a fiscal crisis that ensued because the tax base had hollowed out. Often there was social unrest, with riots and rising crime rates, and it really felt, in the mid-1970s when I was a kid growing up in New York was that the time of the city had come and gone. But something happened. Something changed. And it had a lot more to do with private industry than anything the government did. I tend to think of this as being about what globalization and new techogies did to the returns to skill, the values of high end information-intensive industries that have always had a particular reason to be in urban areas. Proximity is useful for moving industrial goods around, but it's also useful for connecting people. You see this quite visibly in Wall Street and midtown Manhattan, these gigantic clusters of financial services and [?] business patterns that at its height in 2007, 43% of the payroll on the island of Manhattan was in finance and insurance. New York's resurgence was built on finance. Partially this was a global change to support finance. But I tend to see that more generally as being a global change towards information-intensive industries, part of the general rise in returns to skill. And finance has remained rooted, although there certainly is plenty of suburban finance as well, in cities because cities really do have an advantage connecting smart people and enabling them to learn from one another. There's no other industry in which having a bit more knowledge can make you a millionaire overnight. There's no industry where that is as true as in finance. If we look at other cities which have had comebacks, they typically are also tied to information-intensive industries. You think about Boston's comeback based on various sciences, biotech as well as finances. Seattle--1971, two jokers put a sign on the highway: Leaving Seattle, last person to leave town please turn out the lights. Seattle, once again a city very much built on human capital. Think about the companies that now define Seattle--Amazon, Costco, Microsoft, Starbucks. None of these things were really in existence 40 years ago when those guys put up the sign. There was a little bit of action on the Starbucks front. They are all entrepreneurs and it's all very information-intensive, it's all very innovation-intensive related to skilled customers and producers. And that's really what the story is over and over again. If you want a very sort of clear example and sort of the role that globalization plays in this, globalization increases the return to having a good idea, because you can sell it across the whole planet. That is nowhere more tangible than in Hollywood, where the global market for American movies is huge, and yet it is still very geographically rooted in a particular area, which is the cluster of movie creativity. So, I can see posters advertising James Cameron's movie Avatar as I wander through the most disadvantaged areas of India's cities. And yet that globalization is not hurting American cities. It's creating more incentive to be right in the midst of the action in Hollywood. And I think the piece of evidence that I like best is the idea that all this new technology that enables long distance communication isn't making face-to-face contact obsolete. The clearest example I can think of is Silicon Valley itself. Which doesn't look like a traditional city, and of course it is based around the car, but it is still very much in that traditional game of enabling people to connect with one another and to learn from one another, enabling flows of ideas across companies and within companies. And it's not a coincidence that the most information intensive, technology intensive industry is also the one that is the most famous example of a geographic cluster in the world today. It's not a coincidence that Google, which could not be more connected to long distance communication, for its own employees it builds the Googleplex, with very few walls and lots of face-to-face connection where they are all hoping to be with each other learning from each other all the time. That's the sort of narrative that I think works behind this comeback of some, but not all, cities.
46:38Russ: I love that story, but I'm a little bit skeptical about it. I'm quoting you--this is a different way of saying what you just said--"Cities work best when they are filled with smart people and small companies that innovate by exchanging ideas." The part I'm a little skeptical about is the 'exchanging ideas.' You have this image of Silicon Valley or Hollywood or Boston 128, Texas, that there's this ferment, these new ideas; when they come along they infect in a positive way a whole bunch of places. Is that really true? Is it really something more than just the fact that it's efficient, that there's lower search costs, to find new employees, that they're already there when you want to start a new company? Is this idea of exchanging ideas, is it a little overrated, over-romanticized? Guest: It is certainly possible because we, our own industry, is a very innovation-intensive industry and certainly-- Russ: Are you talking about mine and yours? Guest: Yeah. Russ: Education? Guest: Well, education and economics research. Russ: Okay. It's not so innovative in my opinion. But go ahead. Guest: Education, no. Economics research, yes. Sure. Right? I mean, every paper is an attempt to say something new about the world. Russ: Yeah, I'm not sure they're very successful. I'm not sure we've learned a lot since, oh, 1950. But I'll keep an open mind. I'm serious. Carry on. Guest: Well, we certainly think we're in that business. And it is certainly true that in my life's experience and the experience of most of the people I talk to, the role of communication with other economists is critical. And a lot of that communication occurs face to face and fairly random meetings within one's firm and often across firms. That's certainly true in Cambridge and certainly been true in my line. Russ: Well, we give seminars. We go on the road, we give seminars, we talk to other people, we share ideas. Is that going on in Silicon Valley? They don't give a lot of seminars. Guest: But seminars are ideas at a fairly well-developed stage. I think a lot of the sort of creative side occurs well before your paper is designed, when you are still in the process of trying to figure out what the right topic is and how exactly to proceed with your empirical strategy. And that doesn't occur in formal seminars. That occurs in ordinary conversations, while you are walking down the hall or while you are just stopping by someone's office or just while you are having coffee with a colleague from a different university. I've certainly found those incredibly valuable in my life. Russ: I totally agree. I just think education--let's call it research--in general, academic research--is very different from corporate innovation. Or small business innovation. I don't think when a small business comes up with a really great idea, I don't think they share it with anybody. I think they keep it to themselves. Guest: Well, certainly the stories of Silicon Valley from the early days suggested a fair amount of inter-firm collaboration and conversation. Which is somewhat different from the model today. So if we think about Silicon Valley's transition, the 1960s seem to have been an era when there were lots of little firms that talked to each other. The key book on this is Annalee Saxenian's Regional Advantage where she compares Silicon Valley in the 1960s with the Route 128 cluster in Greater Boston. Where the Route 128 cluster was very much that Big Firms walled off from each other, exchanging ideas in the firm perhaps but not very much with other firms. Where she saw Silicon Valley as having lots of people meeting for drinks after work and talking about new production processes and exchanging ideas. The model of Silicon Valley today--and if you think about Google or say, for example, Yahoo's new policy of requiring people to work from home, these are much more like Detroit's giants in the sense that they are very large firms. They are firms that are deeply concerned with the exchange of ideas within their companies but much less likely to have the people in those companies connect with people in other companies. So it may be that you're having an illusion, but there's plenty of history that supports the general notion that there are idea spillovers across firms in Silicon Valley as well. And of course we have the hard evidence of patent citation, which Jaffee, Trajtenberg, Jaffe and Henderson find are more likely to cite patents that are geographically close to them even when they are not in the same company. Russ: Yeah. On the other hand, you have Inside Apple by Adam Lashinsky who documents people in Apple weren't even allowed to share ideas with each other in Apple. Despite the story that Steve Jobs liked to put the mailroom and the bathrooms far away so you'd have to wander around and run into people. There's also a lot of secrecy. I think the story, to me, makes more sense when you think about--it comes back to your point--how unvertically integrated the information technology and computer business is. So my guess is a lot of that synergy takes place among firms that are working together as suppliers and as contractors, and they work on different problems and they have to interface. If they had been vertically integrated we would have lost a lot of that, but the fact that they were not vertically integrated, they were much more--smaller and more nimble, and one would hope more innovation--maybe made a big difference. Guest: It certainly is true that innovations are carried through various actors in this supply chain. And that certainly is right. And there certainly are many other reasons for agglomerating other than just sharing ideas. So I think that certainly is the case. However it does really appear to be true that there are particular agglomerations that are enormously productive, and they do tend to be heavy in idea-oriented sectors.
52:47Russ: You call cities our greatest invention. What do you mean by that and why is it true? Guest: I think it's true precisely because when you look at the greatest hits of humanity--and I guess this gets back to our previous conversation--almost all of them were largely collaborative. And a large number of them involved people learning from other people within cities, through face-to-face interactions. And that's why I think of cities as being so important, because they are enabling us to do what we do best, which is to learn from the people around us. Now obviously that can happen in a company that is far away from an urban center. It can occur in different ways. But the life's blood of the city is enabling us to benefit from people around us. And I guess it's not just about learning, of course; it's about any collaborative enterprise. It's like trade, which started off as being much more geographically restricted than it is now. It's about social connections, and various forms, and cities enable that. All that proximity enables us to work with other human beings, and that is fundamentally--our best asset as a species is being able to work with others. Russ: You want to list some of those greatest hits? Guest: Sure. I'm thinking of Athenian philosophy, Renaissance art, the mass-produced automobile. All of these things are quintessential urban inventions all of which occurred within clusters of genius, where we have very well documented cases of people connecting with each other and learning from each other, and collaboratively producing something much better than anyone could imagine those people would produce on their own. So, in Renaissance art, Florentine art, it starts with Brunelleschi's mathematical comprehension of how linear perspective works, making two-dimensional space appear to be three-dimensional. Which then gets passed along to Donatello, who puts it in the form of low-relief sculpture on the wall of Orsanmichele in Florence. That then gets passed along to their close friend, Masaccio, who puts it on the wall of the Brancacci chapel. Marvellous picture of St. Peter finding a coin in the belly of a fish. Passes along to his friend, Filippino Lippi, passes along to Botticelli, and so forth. All these people knew each other, were borrowing each other's ideas, expanding it, figuring out new ways to use it, and collectively producing something truly and wonderfully marvelous. If you think about the irregular clustering of artistic genius, particularly places in particular times, that isn't because the water is better in Florence. It's not just because of the patronage of the Medicis, for example--much of this stuff occurs before their greatest artistic involvement. That clustering is readily explainable because of the spillovers across people. Because one person comes up with an idea and then other people play with it. A similar thing occurs in France in the late 19th century in French impressionism. People have an invention; they move away from trying to have art that closely captures what we see when we see the outside world to something that's more experimental, and people are riffing on this for 20 years, creating masterpieces. I think I already discussed the Detroit case, but again, it's people who were very proximate to each other, all of them trying out new things. In that case I think you are right, that often the suppliers of various parts where the chains of ideas moving across people. And of course Athenian philosophy is the classic example of people sitting around talking to each other on street corners and in salons and over wine, and all of a sudden a new way of thinking about the world emerges. Russ: That's very beautiful, and I think you are absolutely right. It's interesting to think about how important in those days--the 1500s, France in the 1800s--physical proximity was incredibly important, because you were out of it if you weren't near those folks. Although, at the same time I think of Adam Smith in Edinburgh, in Glasgow. He did make a trip to Europe, but most of the time he was hanging out in Scotland. Pretty far away from the action. Guest: Oh, wait a minute. No. I dispute that. I dispute that because of the Enlightenment. Russ: You had a lot of action there. Guest: Yeah, but not part of the connectedness to Europe. An amazing amount of action. When you think about the people involved in Edinburgh and Glasgow during the heyday of the Scottish Enlightenment, I think it's a fantastic example of how people are learning from-- from Hume-- Russ: Adam Ferguson. Guest: Or think about the chain of people, in exactly the same place, if you want to search the physical sciences, that James Watt learned from. So, James Watt was part of this cluster along the natural sciences side along with creating the steam engine. The Scots had an amazing urban scene at that point in time. Russ: It's true.
57:47Russ: Do you want to close with something about zoning? Guest: This gets to the more general question of governments and cities. First of all, it is clear that there are often negative externalities associated with people living in the same place. Which is why cities were very much at the forefront of certain public services. Which are in fact appropriate. The problem of unclean water in cities actually required a significant amount of public intervention in terms of the water, particularly in the 19th century when it was very difficult to actually monitor the quality of the water. Investments like the Croton Aqueduct were really crucial in changing cities from being the killing fields that they had been. A boy born in New York in 1900 was expected to live 7 years less than the national average. Similarly, cities actually need government in the form of policing. And in the form of dealing with congestion as well. Now, it's possible, in the context of your audience, it's possible to imagine an entirely privatized street system, I guess. I think that's there's lots of upside in things like public-private partnerships in things like new highways. But when it comes to the overall grid of a town, it's possible to imagine doing these things on a private basis, but it's awfully hard to imagine how it would work. I mean, the holdup problems are just enormous. Once you have a public street system you naturally need public policies that mitigate congestion, and I think a [?] on congestion charging is the right way to do those. You could imagine, by the way, having the roads completely owned by a private entity in the sense of a private city. That's not an infeasible thing. But you need some central entity to actually hold it. So cities do need, because there are these negative externalities associated with density, they actually do need government. The problem is that governments often do far too much. So, in the case of land-use regulation, the land use regulation starts off in the 19th century with some fairly sensible-seeming things about, say, fire risks. Huge externality associated with having fire, some limitations about where you are going to put particularly flammable wood buildings is not the craziest thing in the world. But once you sort of start going down that path--and I'm glad that cities at least have footsteps to reduce fire risk--then governments are capable of getting involved in huge amount of regulations that are totally unnecessary and deeply counterproductive. And I think many localities have let themselves be conquered by various interest groups in making it far too difficult to build. This is true in suburbs, which are often capitals of NIMBYism (Not In My Back Yard). It's also true of many older cities that have made it very, very difficult to build up, that have covered great swaths of their territory in historic preservation districts that are essentially no-building zones. And of course the net impact of these things is that they make cities far more expensive than they need to be. And often create a certain amount of uniformity in terms of the income levels that are needed to pay for the high costs of housing in a city that doesn't build. Russ: What would you do about that? Guest: I would substantially ease the building process in most cities. I would drop a fair number of the height limitations. To the extent we think there are actual physical costs and measurable externalities associated with new building, I would proceed with a simple impact fee that one can actually justify rather than having a lengthy, opaque zoning process that does so much to limit new development. In the case of the city historic preservation districts I would probably replace the ever-increasing swatch of territories--15% of the land area in Manhattan south, in the bottom half of Manhattan excluding Central Park as an historic preservation district right now--and areas go into historic preservation districts but they rarely come out of them. So, it seems like it's going to be an ever-increasing swath of the city. I don't much like the idea of cities being museum pieces. There are a few which are appropriate, like Bruges, but I think it's good that cities change and that they develop new space, combination of new activities and people. So, I would in terms of preservation--my father was an architectural historian so I do really believe in the value of preserving some old, beautiful buildings--but I would have a fixed number of the total number of buildings that they are able to set aside as being preserved rather than allow them to just keep on getting new areas for preservation districts. And in general I would also get rid of most barriers to ex-used[?] development. There was a time when you didn't want to have the manufacturing activity right next to the residential district because of the negative externality associated with the factory or the slaughterhouses. But most of what we are looking at right now in terms of urban enterprise is fairly clean, fairly free of major externalities. So there's little reason to have barriers that separate commercial and residential usage. So I would get rid of almost all of that.

Thanks for yet another interesting conversation.

As a Michigan resident, I found the diagnosis of Detroit's woes fascinating.

As a software developer, I found your brief discussion of Silicon Valley and "information technology" to be naive. Collaboration is one of the biggest catalysts for software eating the world. Behemoths and start ups alike are built on top of open source software, and where the software is not core to a company's business model, it is often contributed back to the open source community.

(Aside 1: the side effect of software eating the world is that every company is now a software company in some form.)

(Aside 2: We don't call them "seminars", but I am willing to bet that the software industry gathers at conferences more than any other industry. On Lanyrd.com, most of the 77 events taking place today, Apr 22, are software conferences.)

Disney likely knows more about operating and the cost of operating monorails than any other organization in the world. Wikipedia tells us that, "The system is the most heavily used monorail system in the world." Wikipedia also tells us that the last addition to the system came 15 years ago in 1988. Since then, expansion of Disneyworld's transportation system has been ... more busses.

Both guest Edward Glaeser and host Russ Roberts are right to point out the many ways American urbanization is profoundly artificial:


  • Subsidized Home Ownership Policy is an "Anti-Urban Policy"

  • Real estate markets are dominated by the choice of school districts, and you could have added that

  • Both of these effects are amplified by the fact that the family home is the principal middle class investment.


American urbanization patterns have nothing to do with grass or love of automobiles. It is a warped real-estate market driven by investment and education decisions with very few choices for consumers of living space.

Can we please demolish government incentives that lead to this unnatural coupling of school and investment markets with the market for living space?

Aaron Zierman writes:

If I'm understanding correctly, Mr. Glaeser points most strongly to the exchanging of ideas that has historically taken place inside of cities as being their great "triumph". Essentially, proximity leads to shared ideas which promotes the most growth. I do agree that population centers naturally should have larger, more diverse and available workforce which can aid growth of an entrepreneurial enterprise. However, I have trouble seeing the same value in simple proximity (sharing of ideas) benefit.

Looking into my crystal ball, I see in the future a world which shares much more information and ideas through the internet. Actually, I see in in the present, but full implementation of this advantage is still years away. Like with education, the future is decentralized and online. I see the same for many businesses in many sectors. The ability to adapt and adjust to this new format will be foremost in the successes and failures of business.

Like any adaptation, it will not always be easy. Some will find themselves unable to change and will fade away while new business will take their place. The real difficulty will be in how our generally slow-reacting government adapts. Will they attempt to impede this change because of the temporary pain it may bring? Will the ATMs be again considered a scourge?

This was a good podcast.

Isn't it strange how many government policies contradict each other? Each policy focuses on one item ignoring all the other unseen items and often the same one item is knocked down by a policy that focuses on another one item.

My city is spending $100 million on a streetcar to go 2 miles on an area already covered by a bus route. Their claim is that it will greatly increase property values (ie. housing costs) as if that is automatically a good thing. Oh I forgot. that's "the wealth effect".

Increasing housing costs reduces the ability of poor people to enter the housing market, and reduces the money they have for other expenses, but there will be other programs to fix those problems.

To be conforming, apartment units can not have more than one parking spot per unit, which reduces the number of couples who wish to move downtown. They also want to get rid of parking lots by the farmers market, but most of the customers drive in from the suburbs.

No mention of race? White flight? Seems like a big oversight.

Transportation cost advantages of cities eliminated-- this is as much a result of government policy as anything. The transportation advantage of the city is that you don't need a car to get around. But city policies have been, for decades, focused entirely on accommodating more cars, which is extremely expensive in the context of high land costs.

Detroit sounds like Ireland and potatoes, Interesting podcast but insufficiently aware of automobiles being a blind alley. Even electric automobiles will go extinct for thermodynamic reasons. Best hope for human electric hybrids. You cannot have a one ton vehicle carrying 150 pound person around for often useless activities.
Is there a dose response curve for cities, peak size around ancient Athens? Cities gather resources from the surrounding areas with often long term negative results ( Jared Diamond). If other countries stop lending us oil, will the large high tech cities still be viable?

Regarding the importance of face-to-face contact in high-productivity jobs, I recall interviewing in 1992 for a job at Thinking Machines (then a very hot computer manufacturer). One of my interviewers was a prominent computer scientist, Guy Steele. I asked him what the greatest challenge he faced as a scientist in this fast-growing company. He replied that splitting the company into two buildings (across the street from each other) had a most deleterious effect on the conversations, often informal, that were at the heart of their research.

SaveyourSelf writes:

Edward Glaeser has a really strong understanding of economics. I loved a few of his quotes and ideas:

“Having a very pro-home ownership policy also means you have an anti-urban policy.”

“We probably should be doing more to make sure people pay for the social cost of their actions.”

“So it's not an issue of subsidies for these areas [that need renewal], but it's an issue of making sure you haven't zoned it off … in a way that enables no one to take advantage of that [area].”

“It never made sense for the federal government to subsidize the building of new housing there in the form of urban renewal. And it certainly made no sense after the Highway Aid Act of 1973 to spend hundreds of millions of dollars on a monorail that glides over often-empty streets.”

“Almost all infrastructures can be paid for by users rather than the general tax revenues.”


I am just going to quibble with him over a few things.


“…successful cities today are marked by small firms, smart people, and connections to the outside world.”

This is correct if by “small firms, smart people, and connections to the outside world” you mean competition, diffuse knowledge, and lack of regulatory obstacles.


“The question [whether Silicon Valley will decline] is to what extent do the Silicon Valley firms become dominated by very strong returns to scale, a few dominant firms capitalize on it.”

This is correct if by “a few dominant firms” you mean a decrease in the overall number of firms competing with one another.

“The problem [with Detroit] was the big idea was a vast, vertically integrated factory. And that's a great recipe for short run productivity, but a really bad recipe for long run reinvention.”

The question Russ posed is really why Detroit has such a low standard of living. When people trade in an environment that is competitive, well informed, and free of all regulations aside from the precepts for Justice then standard of living is maximized for everyone. The same model works well in reverse, so that if an economy like Detroit has a low standard of living, you know already that it lacks trade, competition, diffuse information, freedom, or justice.
The problem with Detroit, therefore, was not the idea of a large vertically integrated factory. It was the idea that the city and its people were better off with a few large car companies and a few large unions rather than many small companies and many individual employees competing with each other. So, like clockwork, every time a small car company in America became successful a larger one would buy it, reducing competition. Simultaneously, the government (both federal and local) created laws protecting the large car companies from other foreign and domestic automakers and protecting large Unions from other individuals seeking employment. Lacking the incentive to continually innovate that only competition can provide, the car companies stagnated and the employees’ skills stagnated until, eventually, competition (Honda, Toyota, Hunyadi, Kia) broke through the trade barriers and reduced the whole city to ruin. And that is only the part of the story dealing with "competition." The violation of "Justice and Freedom" to which the American government subjects its citizens is a never ending tale of the myriad ways to reduce all of society’s standard of living. The only consistently positive predictor of high standard of living in America is "Diffusion of Information" thanks to constitutional protections of speech and press.
Thank god for the First Amendment.

Ken P, I know generally where you live and yes it is absolutely silly to waste hundreds of millions on this kind of project EVEN IF IT IS ENTIRELY FUNDED BY Fed and/or State money as at some time in the future that source will stop or more likely the costs will rise faster than the funding forcing the locals to make up the difference. I think that both people in the podcast would absolutely agree with you.

I think that part of the issue with cities is that they over govern their subjects. This is especially true in poor urban areas where once people get the attention of regulators and local police they get squashed. I just spoke to a woman at work who had a side job building fake flower arrangements and I asked why not build real flower arrangements BUT SHE NEEDS A LICENSE FOR THAT. Just try to get a taxi to serve you in a poor and dangerous area. Why not get rid of these insane licensing rules?

Though rather "hectic" in structure, this useful podcast made me add "cities" to "state" and "federal" as a level of government, thanks to the guest. Or at least it was. Have "cities" become even more subordinate to Federal money than "states"? (I explicitly exclude the UN.)

Two immediate reactions from my own experience. Home ownership is NOT anti-urban. Consider the individual, not un-detached rowhouses of Philadelphia, Baltimore, and other Eastern cities. They might be defined as having a common roof-line and separated by brick (fireproof) firewalls. Built on streets about two automobiles wide in blocks of a hundred or more, they constituted the majority of city homes in the 30s to 50s.

Nor excluded did this construction exclude the poor: it was pathway to home ownership for the poor when the cities provided public transportation (street cars) and public utility services.

Excellent podcast. Insightful guest. I only missed a more throughout discussion of white flight and changing demographics.

In the 50s, before "silicon valley" or "Route 128 cluster", there was "Delaware Valley USA." Birth place of the computer industry and home to Univac (and Grace Hopper), RCA Computer Division, Burroughs, Emerson, Philco, Sylvania, GE, a little bit North, IBM. I tried to find the first published use of "Silicon Valley" but failed. Any one know?

Sigificantly, this was before software could be patented anywhere. The Constitution and our fore-fathers wanted to give the inventor ownership of his invention but the most recent change to the US Patent Law gives this honor to the first to file. Contrary to Dr. Robert's thought, Trade Secrets are possible under US law. Or should I say, "Were possible."

Hi, I'm Jim and I am physics-challenged. I know it is all about ecology, energy transfers and power principles but these were neglected in my education. I do know what EROEI stands for. I do not make policy decisions.
Detroit was more positive in the early days because there were no cars. Just as Thomas Jefferson was more productive without television and telephones. The average Econ would not buy a car and would certainly not borrow to buy a car( early Henry Ford stance). The energy efficiency of a car is at best 15%,probably closer to 1-2%. A car will never repay a loan with interest. Borrowing to buy unproductive assets like autos was popular in the 1920s, and is popular again (72 month sub prime car loans). Similar outcome?
I acknowledge a greater power and She bats last.

On the subject of whether Silicon Valley gives seminars:

Is that going on in Silicon Valley? They don't give a lot of seminars

In fact, Silicon Valley in the small and the tech community in the large host hundreds of conferences around sharing knowledge every year. Here's a good place to look at what's happening; you can filter by topic and location. Note that there are conferences based not just on technical programming topics, but also business-centric ones.

The physicist, Geoffrey West, expresses the energy dynamics of cities in mathematical models. There is a TED talk, a Long Now seminar and a Discover article. Also worries about overshoot and collapse as in Detroit.

Russ, I applaud your podcast for the very thoughtful investigation of interesting topics. I believe I have only heard the expression 'confirmation bias' on your program, what a joy it would be to hear more often. I wonder about the frequently occurring theme regarding privatizing schools. I think it is a given that, generally, the poorer the parents the less access they will have to finer schools. How will privatizing schools change this? I suspect that x0% ish of the US population only have access to one school for a given age of a child (rural). There simply isn't the demand, in many markets, to have supply diversity. However, my greatest concern is that working parents simply will not be able to overcome the market barriers to exploiting a private education system, specifically transportation access and costs (dollars and time). As a relatively well off working American, I would find it quite an obstacle to arrange for a n elementary aged child to attend school in a distant part of the community. Perhaps information technology innovation can help here, but Google thrives on face-to face contact, and I suspect a good school would not succeed without the same. I mean that education can never be entirely accomplished on a computer screen. How can these issues be overcome? Never mind that vouchers will always be supplemented with personal income in better off households, once again putting disadvantaged Americans at the bottom of the food chain. My ideal of education in the US is that it is the 'equalizer' of opportunity, and provides a vector to success and productivity to all citizens . I would love to hear the 'pragmatic' approach to privatization podcast. Regards

Michael Caffrey,

A few thoughts, but I would like to do a full podcast on it.

Money spent is not the only determinant of success in education. We know that from the current system. The current system does not match your ideal. It brutally fails the poorest kids.

If schools are not tied to housing, housing prices would not be as correlated with the quality of the local schools.

Maybe schools would find it worthwhile to make it easy for kids to come to school.

I think generous people would augment private money with charity.

If people spent their own money, I think they would invest more time and energy in the schools their kids attend.

More down the road, I hope. Good suggestion.
