They discuss the criteria used to determine the greatest economist of all time, including breadth and depth of work, historical importance, and contributions in both micro and macroeconomics. They also explain why Marx and Samuelson are not considered for the title.
Who is the greatest economist of all time? In Tyler Cowen's eclectic view, you need both breadth and depth, macro and micro. You can't have been too wrong--and you need to be mostly right. You have to have had a lasting impact, and done both theory and empirical work. If you meet all these criteria, you may just be history's greatest economist. Listen as Cowen talks about his new and freely accessible book GOAT with EconTalk's Russ Roberts. Along the way to crowning a winner, Cowen offers original insights into what shaped the theories and worldviews of the greatest economists of all time. Cowen and Roberts also talk about the evolution of economics from a field concerned mainly with ideas to one that mostly grapples with empirical challenges.
