In the latest EconTalk, I talk with David Henderson  about whether it’s reasonable to presume that economists agree on various issues such as the minimum wage, trade, the causes of growth or the sources of inflation. I used to agree with David that in the area of microeconomics, there is much more consensus than in macroeconomics. Lately, I’m not so sure. At the end of the conversation, I raise the issue of incentives. As the market for talking economists has expanded, I believe that economists do more talking and that the reward for taking polemical stands has increased.
