单选题 In both developed and developing nations, governments finance, produce, and distribute various goods and services. In recent years, the range of goods provided by the government has extended broadly, including many goods that do not meet the economic purist's definition of "public goods". As the size of the public sector has increased steadily,there has been a growing concern about the effectiveness of the public sector's performance as producer. Critics argue that the public provision of certain goods is inefficient and have proposed that the private sector should replace many current public sector activities, that is, these services should be privatized. Since 1980s, greater privatization efforts have been pursued in the United States. Concurrent with this trend has been a strong endorsement (support) by international bilateral donor (aid) agencies for heavier reliance on the private sector in developing countries. The underlying claim is that the private sector can improve the quality of outputs and deliver goods more quickly and less expensively than the public sector in these countries. This claim, however, has mixed theoretical support and little empirical verification in the Third World. The political, institutional, and economic environments of developing nations are markedly different from those of developed countries. It is not clear that the theories and empirical evidence that claim to justify privatization in developed countries are applicable to developing nations. Often policy makers in developing nations do not have sufficient information to design effective policy shifts to increase efficiency of providing goods through private initiatives. Additionally,there is a lack of basic understanding about what policy variables need to be altered to attain desired outcomes of privatization in developing countries. One study of privatization in Honduras examined the policy shift from "direct administration" to "contracting out" for three construction activities: urban upgrading for housing projects, rural primary schools, and rural roads. It tested key hypotheses applying to the effectiveness of privatization, focusing on three aspects: cost, time, and quality. The main finding was that contracting out in Honduras did not lead to the common expectations of its proponents because institutional barriers and limited competitiveness in the marketplace have prevented private contractors from improving quality and reducing the time and cost required for construction. Privatization in developing countries cannot produce goods and services efficiently without substantial reform in the market and regulatory procedures. Policy makers interested in privatization as a policy measure should consider carefully the multiple objectives at the national level.
