Rubinstein on Game Theory and Behavioral Economics

EconTalk Episode with Ariel Rubinstein
Hosted by Russ Roberts

Ariel Rubinstein of Tel Aviv University and New York University talks with EconTalk host Russ Roberts about the state of game theory and behavioral economics, two of the most influential areas of economics in recent years. Drawing on his Afterword for the 60th anniversary edition of Von Neumann and Morgenstern's Theory of Games and Economic Behavior, Rubinstein argues that game theory's successes have been quite limited. Rubinstein, himself a game theorist, argues that game theory is unable to yield testable predictions or solutions to public policy problems. He argues that game theorists have a natural incentive to exaggerate its usefulness. In the area of behavioral economics, Rubinstein argues that the experimental results (which often draw on game theory) are too often done in ways that are not rigorous. The conversation concludes with a plea for honesty about what economics can and cannot do.

Munger on Microfinance, Savings, and Poverty

EconTalk Episode with Mike Munger
Hosted by Russ Roberts

Mike Munger of Duke University talks with EconTalk host Russ Roberts about microfinance. Munger argues that cultural forces make it difficult for some families to save, and the main value of microfinance is to allow a higher level of savings. Families are willing to save via microfinance even though returns can be negative. Munger argues that this counterintuitive result is possible when other means of savings are unavailable. Munger also discusses microfinance that is used for entrepreneurship and the potential role for microfinance in development.

Rodrik on Globalization, Development, and Employment

EconTalk Episode with Dani Rodrik
Hosted by Russ Roberts

Dani Rodrik of Harvard University talks with EconTalk host Russ Roberts about trade, the labor market, and trade policy. Drawing on a recent paper with Margaret McMillan on trade and productivity, Rodrik argues that countries have very differing abilities to respond to increases in productivity that allow production to expand using fewer workers in a particular sector. When workers are displaced by productivity increases, what is their next best alternative? Rodrik discusses how this varies across countries and policies that might improve matters. He argues that poor countries should subsidize new products as a way of overcoming uncertainty and externalities from new ventures.
