The most influential strategy for the transition to a market economy was that adopted by Poland launched in January 1990. The strategy was strongly influenced by IMF and World Bank analyses of successful and unsuccessful stabilization programmes which had been adopted in Latin America in the 1980s. The strategy incorporated a number of interdependent measures including macro-economic stabilization; the liberalization of wholesale and retail prices; the removal of constraints to the development of private enterprises and the privatization of state-owned enterprises; the elimination of subsidies and the imposition of hard budget constraints; and the creation of an export-oriented economy that was open to foreign trade and investment. The creation of a social safety net targeted at the individual to compensate for the removal of job security and the removal of price controls on staple goods was also part of the strategy.
