Privatization and the sources of performance improvement in the global telecommunications industry

Abstract This paper examines the financial and operating performance of 31 national telecommunication companies in 25 countries that were fully or partially privatized through public share offering. Using conventional pre- versus post-privatization comparisons and panel data estimation techniques, we find that the financial and operating performance of telecommunications companies improves significantly after privatization, but that a sizable fraction of the observed improvement results from regulatory changes—alone or in combination with major ownership changes—rather than from privatization alone.

Sources of Performance Improvements in Privatized Firms: A Clinical Study of the Global Telecommunications Industry

This paper examines the financial and operating performance of 31 national telecommunication companies in 25 countries that were fully or partially privatised through public share offering between October 1981 and November 1998. Using conventional pre- versus post-privatisation comparisons, we find that profitability, output, operating efficiency and capital investment spending increase significantly after privatisation, while employment and leverage decline significantly. However, these univariate comparisons do not account for separate regulatory and ownership effects (retained government stake), and almost all telecoms are subjected to material new regulatory regimes around the time they are privatised. We examine these separate effects using both random and fixed-effect panel data estimation techniques for a seven-year period around privatisation. We verify that privatisation is significantly related to higher profitability, output and efficiency, and with significant declines in leverage. However, we also find numerous separable effects for variables measuring regulation, competition, retained government ownership and foreign listing (on U.S. and U.K. exchanges). Competition significantly reduces profitability, employment and, surprisingly, efficiency after privatisation, while creation of an independent regulatory agency significantly increases output. Mandating third party access to an incumbent - network is associated with a significant decrease in the incumbent - investment and an increase in employment. Retained government ownership is associated with a significant increase in leverage and a significant decrease in employment, while price regulation significantly increases profitability. Major efficiency gains result from better incentives and productivity, rather than from wholesale firing of employees and profitability increases appear to be caused by significant reductions in costs - rather than price increases. On balance, we conclude that the financial and operating performance of telecommunications companies improves significantly after privatisation, but that a sizeable fraction of the observed improvement results from regulatory changes - alone or in combination with ownership changes - rather than from privatisation alone.

The Rise of Accelerated Seasoned Equity Underwritings

Seasoned equity offerings (SEOs) executed through accelerated underwritings have increased global market share recently, raising over

850 billion since 1998, and now account for over half (two-thirds) of the value of U.S. (European) SEOs. We examine 31,242 global SEOs, executed during 1991-2004, which raise over

2.9 trillion for firms and selling shareholders. Compared to fully marketed deals, accelerated offerings occur more rapidly, raise more money, and require fewer underwriters. Importantly, accelerated deals reduce total issuance cost by about 250 basis points. Accelerated deals sell equal fractions of primary and secondary shares, whereas in traditional SEOs primary shares dominate. Announcement period returns are comparable for traditional and accelerated offerings, while secondary and mixed offerings trigger more negative market responses than do primary offerings. We conclude that this rapid, worldwide shift towards accelerated underwriting creates a spot market for SEOs, and represents the long-predicted shift towards an auction model for seasoned equity sales.

The Political Economy of Privatization

We construct a comprehensive panel data of 92 publicly traded European utilities over the period 1994-2005 in order to study the relationship between capital structure, regulated prices, and firm value, and examine if and how this interaction is affected by ownership structure and regulatory independence. We show that regulated firms in our sample tend to have a higher leverage if they are privately-controlled and if they are regulated by an independent regulatory agency. Moreover, we find that the leverage of these firms has a positive and significant effect on their regulated prices, but not vice versa, and it also has a positive and significant effect on their market values. Our results are consistent with the theory that privately-controlled firms use leverage strategically to shield themselves against regulatory opportunism.

Privatization in Western Europe Stylized Facts, Outcomes, and Open Issues

Nontradable shares (NTS) are an unparalleled feature of the ownership structure of Chinese listed companies and represented a major hurdle to domestic financial market development. After some failed attempts, in 2005 the Chinese authorities have launched a structural reform program aiming at eliminating NTS. In this paper, we evaluate the stock price effects of the actual implementation of this reform in 368 firms. The NTS reform generated a statistically significant 8 percent positive abnormal return over the event window, adjusting prices for the compensation requested by tradable shareholders. Results are consistent with the expectation of improved economic fundamentals such as better corporate governance and enhanced liquidity.

From Government to Regulatory Governance: Privatization and the Residual Role of the State

This paper provides an empirical analysis of the role of political institutions in privatization. The empirical testing relies on a new political database with continuous and time-varying measures of the political-institutional setting, and of the partisan orientation of the executive. Using panel data for 21 industrialized countries in the 1977-1999 period, first we show the likelihood and the extent of privatization to be strongly and positively associated with majoritarian political systems. On the contrary, in consensual democracies privatization seems delayed by a “war of attrition” among different political actors. Second, we identify a partisan determinant of the choice of the privatization method. As theory predicts, right wing executives with re-election concerns design privatization to spread share ownership among domestic voters.

Capital Structure and Regulation: Does Ownership Matter?

Privatization has certainly been one of the main events of the economic and financial history of the 20th century. Between 1997 and 2004 more than 4,000 privatization operations were carried out in the world, bringing to governments revenues for over 1,350US

billion. Western Europe emerges as the most important region, having implemented the greatest number of privatizations and raised a half of global revenues. The relevance of Western Europe in the process can be ascribed to several factors. This paper investigates the causes of this process, summarizes the main trends of privatization activity at the country level, analyzes the main privatization drivers and provides an account of the main findings of the effects of privatization at the macro and microeconomic level.
