Introduction The political and economic policy of privatization, broadly defined as the deliberate sale by a government of state-owned enterprises (SOEs) or assets to private economic agents, is now in use worldwide. Since its introduction by Britain’s Thatcher government in the early 1980s to a then-skeptical public (that included many economists), privatization now appears to be accepted as a legitimate – often a core — tool of statecraft by governments of more than 100 countries. Privatization is one of the most important elements of the continuing global phenomenon of the increasing use of markets to allocate resources. It is tempting to point to the spread of privatization programs around the world during the past two decades and conclude that the debate on the economic and political merits of government versus private ownership has been decided. But such a conclusion is flawed since twenty years ago proponents of state ownership could just as easily have surveyed the postwar rise of state-owned enterprises and concluded that their model of economic organization was winning the intellectual battle with free market capitalism. Instead of pointing to the spread of privatization and calling it destiny, our goal is to assess the findings of empirical research on the effects of privatization as a policy. Therefore, this paper surveys the rapidly growing literature on privatization, attempts to frame and answer the key questions this stream of research has addressed, and then describes some of its lessons on the promise and perils of selling state-owned assets. Throughout this survey, we adopt the perspective of an advisor to a government policymaker who is wrestling with the practical problems of whether and how to implement a privatization program. The policymaker asks “What does the research literature have to tell us about these aspects of privatization as an economic policy?” We attempt to answer these important questions. This paper is organized as follows. Section 2 provides a brief historical overview of privatization. We examine the impact that privatization programs have had in reversing SOE involvement in the economic life of developed and developing countries. Section 3 briefly surveys the recent theoretical and empirical research on the relative economic performance of state-owned and privately owned firms. Section 4 details the different types of transactions that are labeled “privatization” in different regions. We draw particular attention to the structure and pricing selected for share issue privatizations. We also evaluate the various forms of “voucher” or “mass” privatizations that have been implemented. This section also examines whether less radical methods of improving the performance of SOEs, such as deregulation and allowing greater competition (or more routine steps such as using management performance contracts), can effectively substitute for outright privatization. In Section 5, we examine the issue of whether, and by how much, privatization programs have actually improved the economic and financial performance of divested firms. Our discussion first evaluates privatization in industrialized and developing countries, and then assesses privatization’s overall impact in the transition economies. Section 6 asks whether domestic and international investors who purchase privatizing share offerings experience positive initial and long- term investment returns, and Section 7 evaluates the impact of privatization on the development of non-US capital markets over the past two decades. Finally, Section 8 discusses how privatization programs have impacted the development of—and interest in—corporate governance practices around the world. Section 9 concludes and summarizes our survey. 2. How Large Has the Impact of Privatization Been to Date? Given the attention the press has given to the global movement toward markets, especially the privatization of state-owned enterprises, some might conclude that privatization has almost ended the involvement of state-owned enterprises in global economic activity.1 This is a significant overstatement. To understand the impact of privatization on the state’s role in different economies, we must first briefly review the history behind both privatization and its precursor, nationalization. Throughout history, there has been a mixture of public (often including religious institutions) and private ownership of the means of production and commerce. Sobel (1999) writes that state ownership of the means of production, including mills and metal working, was common in the ancient Near East, while private ownership was more common in trading and money lending. In ancient Greece, the government owned the land, forests, and mines, but contracted out the work to individuals and firms. In the Ch'in dynasty of China, the government had monopolies on salt and iron. Sobel notes that in the Roman Republic the "publicani (private individuals and companies) fulfilled virtually all the of the state's economic requirements." Rondinelli and Iacono (1996) note that by the time of the Industrial Revolution in the western industrialized societies and their colonies, the private sector was the most important producer of commercial goods and was also important in providing public goods and services. This pattern, with more government involvement in some countries and less in others, continued into the twentieth century in both Western Europe and its colonies and former colonies. In the United States, there was less government involvement than many other countries. The Depression, World War II, and the final breakup of colonial empires pushed government into a more active role, including ownership of production and provision of all types of goods and services, in much of the world. In Western Europe, governments debated how deeply involved the national government should be in regulating the national economy and which industrial sectors should be reserved 1 Throughout this paper, we will use the World Bank’s definition of state-owned enterprises, as described in Haggarty and Shirley (1995): “government-owned or government-controlled economic entities that generate the bulk 2 exclusively for state ownership. Until the Thatcher government came to power in 1979, the answer to this debate in the U.K and elsewhere was that the government should at least own the telecommunications and postal services, electric and gas utilities, and most forms of non-road transportation (especially airlines and railroads). Many politicians also believed the state should control certain “strategic” manufacturing industries, such as steel and defense production. In many countries, state-owned banks were also given either monopoly or protected positions, as discussed in La Porta, Lopez-de-Silanes and Shleifer (2000a). Rondinelli and Iacono (1996) argue that government ownership grew in the developing world for slightly different reasons, primarily that government ownership was perceived as necessary to promote growth. In the post-colonial countries of Asia, Africa, and Latin America, governments sought rapid growth through heavy investment in physical facilities. Another reason for government ownership, often through nationalization,
