Privatization was the fundamental pillar of transition from plan to market in former socialist countries. But little is known about the fate of companies that were privatized in large scale privatization schemes such as mass privatization or management-employee buyouts. This is the first original study aiming to fill this gap. It assesses wholesale privatization schemes in three leading transition countries - the Czech Republic, Poland and Slovenia - in terms of the evolving concentration of ownership and relations to firm performance.
