Transition economies are going through a process of changing the role of the state, allowing a greater role for the private sector. This is consistent with the market-oriented approach of the WTO. Remaining state agencies and enterprises will need to adapt their ways of doing business, including in their approach to procurement of goods and services, for economic and legal reasons. There is some hesitation about privatization, as for foreign direct investment, and, where accepted, about the precise timing. Where privatization of basic service monopolies occurs, the role of the state shifts towards a regulatory function. In some private sector activities, a non-interventionist approach to competition may be justified by market considerations, while in others a pro-active policy may be necessary to ensure the benefits of economic liberalization.
