According to leading economic theorists, creating capitalism out of communism requires rapid privatization. In this article we empirically test the welfare implications of privatization policies in Post-Soviet countries by using cross-national panel mortality data as an indicator of social costs. We find that rapid privatization ñ whether measured by a novel measure of mass privatization program implementation or Enterprise Bank for Reconstruction and Development privatization outcome scores ñ is a critical determinant of life expectancy losses, and that when privatization policies are reversed, life expectancy improves. Using selection models, we show that endogeneity understates the social costs of rapid privatization.http://deepblue.lib.umich.edu/bitstream/2027.42/64393/1/wp890.pd
