The Direct Costs and Benefits of US Electric Utility Divestitures

This paper studies the impact of divestiture on the efficiency and costs of electric utilities. The empirical literature shows that there exist economies of scope for electric utilities and that divestiture decreases distribution efficiency but increases generation efficiency. This paper is to bring together these different results. Our analysis covers distribution, transmission, and power sourcing. Our data is an unbalanced panel of about 138 US electric utilities for the years 1994 to 2006 over which we observe 30 divestitures between 1997 and 2003. First, we regress firmlevel efficiencies for distribution and power sourcing on various divestiture indicators. Second, we compare the weighted cost between divested and non-divested firms and calculate a net present value for the entire sample of divestitures. Last, we regress net benefits from divestiture on the distribution side on the net benefit for power sourcing to see whether individual firms successfully off-set any costs of divestiture. We find that divestiture reduces distribution efficiency but increases power sourcing efficiency. Both effects depend on the amount of own nuclear generation output but not fossil-fuel or hydro output. The net present value for all divestitures in our sample is $11.3 billion. It seems that relatively lower costs of power outweigh losses in economies of scope as well as other restructuring costs. However, lower costs of power might be the result of favourable contracts put in place at the time of divestiture. Our study complements traditional studies of economies of scope and shows that divestitures might well be worth it

Antitrust Policy and Industrial Policy: A View from the U.S.

This paper discusses the tensions between antitrust policy and industrial policy from a U.S. perspective. In the late 1970s and the 1980s, in the wake of the slowdown of the U.S. economy and the apparent ascendancy of the Japanese economy, the pluses and minuses of a formal industrial policy were debated in the U.S.; but there was never an explicit adoption of anything that had the appearance of a formal industrial policy. Nevertheless, there is a long tradition of governmental intervention in the U.S. that is at odds with the spirit and letter of antitrust policy's pursuit of more competitive and efficient markets.After offering definitions of antitrust and of industrial policy, this paper offers details on the types of governmental intervention that are at odds with antitrust. It then provides some reflections on the reasons for these tensions and conflicts.

The Growing Influence of Economics and Economists on Antitrust: An Extended Discussion

Over the past two to three decades economics has played an increasingly important role in the development of U.S. antitrust enforcement and policy. This essay first reviews the major facets of U.S. antitrust enforcement and next reviews the ways in which economics -- starting from a low base -- has grown in importance in antitrust. The essay then highlights three antitrust areas in which the influence of economics has had the greatest influence: merger analysis, vertical relationships, and predatory pricing. The essay concludes with the identification of four antitrust areas where further economics analysis could have high returns.

The New Industrial Organization and Small Business

The small business sector is an important part of the American economic landscape, in both absolute and relative terms. Despite its absolute growth, however, the sector accounts for a diminishing share of private sector activity. But its importance, and changes in importance, vary across industrial sectors of the economy. Drawing on the theoretical and empirical insights developed in recent books by John Sutton, we suggest that the presence or absence of endogenous strategic behaviors of the larger firms with respect to advertising, promotion, research and development, and other sunk cost expenditures may well play an important role in explaining the differing levels of small business importance, both cross-sectionally and over time. We conclude the paper with suggestions for research directions that could shed further light on these ideas

Asia-Pacific telecommunications liberalisation and productivity performance

This study examines the growth in total factor productivity (TFP) of 12 Asia-Pacific telecommunications carriers for the period 1987 through 1990. Carriers are chosen to represent the stages of telecommunications liberalisation identified by the International Telecommunication Union (1995a). A model relating TFP growth to output growth, changes in output mix, technology change and market competition and private ownership is estimated on a unique data set obtained from telecommunications carrier annual reports. Empirical results show competition, private ownership, technology change and scale economies improve carrier TFP growth.Asia-Pacific telecommunications; liberalisation and productivity performance
