Learning the wealth of nations

Résumé

We study the evolution of market-oriented policies over time and across countries. We consider a model in which own and neighbors' past experiences influence policy choices, through their effect on policymakers' beliefs. We estimate the model using a large panel of countries and find that it fits a large fraction of the policy choices observed in the postwar data, including the slow adoption of liberal policies. Our model also predicts that there would be a number of reversals to state intervention if nowadays the world was hit by a shock of the size of the Great Depression.
