Privatization and Its Benefits: Theory and Evidence

Privatization has been a key component of structural reformprograms in both developed and developing economies. The aimof such programs is to achieve higher microeconomic efficiencyand foster economic growth, as well as reduce public sectorborrowing requirements through the elimination of unnecessarysubsidies. Microeconomic theory tells us that incentive andcontracting problems create inefficiencies due to public ownership,given that managers of state-owned enterprises pursue objectivesthat differ from those of private firms (political view) andface less monitoring (management view). Not only are the managers'objectives distorted, but the budget constraints they face arealso softened. The soft-budget constraint emerges from the factthat bankruptcy is not a credible threat to public managers,for it is in the central government's own interest to bail themout in case of financial distress. Empirical evidence showsa robust corroboration of theoretical implications: privatizationincreases profitability and efficiency in both competitive andmonopolistic sectors. Full privatization has a greater impactthan partial privatization and monopolistic sectors show anincrease in profitability that is above the component explainedby increases in productivity, which reflects their market power.From the macroeconomic perspective, no conclusive evidence canbe drawn, but the trends are favorable.
