This paper estimates the effects of privatization on worker separations and wages using retrospective data from a national probability sample of Ukrainian households. Detailed worker characteristics are used to control for compositional differences and to assess types of observable "winners" and "losers" from privatization. Pre-privatization worker-firm matches are used to control for unobservables in worker and firm selection. The results imply privatization reduces wages by five percent and cuts the layoff probability in half. Outside investor ownership reduces separations but leaves wages unaffected. Winners from privatization tend to be higher skilled employees of larger firms, but there is no discernible relationship with gender, education, or experience.
