In this episode, we sit down with Assoc. Prof. Kirsten Wandschneider to talk about the monetary disintegration that plagued the interwar period. How did countries choose to go back on the Interwar Gold Standard? How did this constrain policy choices? Why did countries eventually leave and why was the interwar standard so shortlived? We also review the performance of countries who remained on gold compared with those who imposed various types of capital controls based on Kirsten's work. We finish by considering her recent efforts to quantify the effects of the 1930s currency wars on international trade.
