Scott Sumner of Bentley University and the blog, The Money Illusion, talks with EconTalk host Russ Roberts about the last 30 years of economic policy and macroeconomic success and failure. Sumner argues that there was a neoliberalism revolution beginning in the 1980s around the world, an era of deregulation, privatization and falling marginal tax rates. Sumner argues that the states that liberalized the most had the most successful economic results. Roberts argues that it is difficult to assess the independent effect of various policy changes and points to many areas--in the United States at least--where government involvement increased in important parts of the economy, and Sumner responds. Sumner also talks about the importance of culture in economic performance.
