inefficient and uncompetitive enterprises especially from the over-grown industrial sector. These initial conditions meant that, in the early stages of transition, the volume of entries and exits will be, by necessity, very high ­ reflecting the large scale changes that had to take place before these economies attain a macroeconomic structure consistent with their level of development and with the needs of a market-based economy open to internationalcompetition. One of the main elements of the reform programme in all economies in transition was the liberalisation of entry conditions. Along with the liberalisation of prices and foreign trade, appropriate measures facilitating the establishment of new enterprises were approved in the very early phase of reforms in all of these countries. The effectiveness of liberalised entry conditions, of course, depends on the presence of appropriate legal and institutional framework in which new firms will operate. The establishment of a conducive legal and institutional environment, however, takes much longer. In practice, new firms come into existence before the rules of the game are properly established. These rules develop gradually and are not always, and everywhere, consistent with the aim of liberalising the entry conditions. The conditions facing new firms, therefore, have fluctuated in some countries in accordance with changes in the political environment and in line with the strength of different lobbies and interest groups.
