Sunk costs, market contestability, and the size distribution of firms

This paper offers a new economic explanation for the observed inter-industry differences in the size distribution of firms. The empirical estimates--based on three temporal (1982, 1987, and 1992) cross-sections of the four-digit United States manufacturing industries--indicate that increased market contestability, as signified by low sunk costs, tends to reduce the dispersion of firm sizes. These findings provide support for one of the key predictions of the theory of contestable markets: that market forces under contestability would tend to render any inefficient organization of the industry unsustainable and, consequently, tighten the distribution of firms around the optimum.Markets and Market Access,Economic Theory&Research,Water and Industry,Access to Markets,Debt Markets

The pricing dynamics of utilities with underdeveloped networks

This paper uses an analytically tractable intertemporal framework for analyzing the dynamic pricing of a utility with an underdeveloped network (a typical case in most developing countries) facing a competitive fringe, short-run network adjustment costs, theft of service, and the threat of a retaliatory regulatory review that is increasing with the price it charges. This simple dynamic optimization model yields a number of powerful policy insights and conclusions. Under a variety of plausible assumptions (in the context of developing countries) the utility will find its long-run profits enhanced if it exercises restraint in the early stages of network development by holding price below the limit defined by the unit costs of the fringe. The utility's optimal price gradually converges toward the limit price as its network expands. Moreover, when the utility is threatened with retaliatory regulatory intervention, it will generally have incentives to restrain its pricing behavior. These findings have important implications for the design of post-privatization regulatory governance in developing countries.Economic Theory&Research,Markets and Market Access,Urban Water Supply and Sanitation,Infrastructure Regulation,Access to Markets

Restructuring regulation of the rail industry for the public interest

Throughout the world, the rail industry historically has been one of the most extensively regulated of all sectors. Price, entry, exit, financial structure, accounting methods, vertical relations, and operating rules have all been subject to some form of government control. The public utility paradigm of government regulation has been applied on the assumption that the economic characteristics of the rail industry preclude competitive organization or the need for market responsiveness. In the past three decades, however, policymakers and economists have become increasingly critical of traditional regulation of the rail industry. It is generally accepted that in markets where rail carriers seek to meet demand, there is often effective competition, and that government restrictions on the structure and conduct of firms in this industry impose considerable costs on society. Misguided regulatory policies have been blamed for the misallocation of freight traffic among competing modes of transport, excess capacity, excessive operating costs, and poor investment decisions. Regulatory controls have also shouldered much of the blame for the poor financial condition of railroads, the deterioration of rail plant, the suppression and delay of cost-reducing innovations, and the mediocre quality of rail service. The authors suggest principles for restructuring railroad regulation - indeed, for restructuring the orientation of railroad entries - for the sake of public interest. Much can be learned, they contend, from applying the principles of industrial organization to analysis of the rail industry. To assess the implications of policies aimed at rate regulation or infrastructure, it is essential to understand the nature of technology, costs, and demand in the rail industry. Government's role in relation to market behavior should be based explicitly on the economic and technological realities of the railroad marketplace. The authors say that restructuring along the lines they suggest - putting more emphasis on marketing effectiveness - will result in a more profitable railway with a better chance of covering its costs for commercial services. Changing the basis for noncommercial services as they suggest will make those services more effective at fulfilling public policy objectives, will eliminate an insuperable drain on revenues that condemns rails to inadequate investment, and will eliminate cross-subsidies that make it difficult for rails to compete against other modes of transport.Markets and Market Access,Economic Theory&Research,Environmental Economics&Policies,Decentralization,Enterprise Development&Reform,Banks&Banking Reform,Economic Theory&Research,Environmental Economics&Policies,Markets and Market Access,Access to Markets

Towards a Sustainable Global Energy Supply Infrastructure: Net Energy Balance and Density Considerations

This paper employs a framework of dynamic energy analysis to model the growth potential of alternative electricity supply infrastructures as constrained by innate physical energy balance and dynamic response limits. Coal- red generation meets the criteria of longevity (abundance of energy source) and scalability (ability to expand to the multi-terawatt level) which are critical for a sustainable energy supply chain, but carries a very heavy carbon footprint. Renewables and nuclear power, on the other hand, meet both the longevity and environmental friendliness criteria. However, due to their substantially di¤erent energy densities and load factors, they vary in terms of their ability to deliver net excess energy and attain the scale needed for meeting the huge global energy demand. The low power density of renewable energy extraction and the intermittency of renewable ows limit their ability to achieve high rates of indigenous infrastructure growth. A signi cant global nuclear power deployment, on the other hand, could engender serious risks related to proliferation, safety, and waste disposal. Unlike renewable sources of energy, nuclear power is an unforgiving technology because human lapses and errors can have ecological and social impacts that are catastrophic and irreversible. Thus, the transition to a low carbon economy is likely to prove much more challenging than early optimists have claimed.dynamic energy analysis; alternative electricity supply; coal; nuclear energy

Toward a sustainable global energy supply infrastructure : net energy balance and density considerations

This paper complements previous work on the economics of different energy resources by examining the growth potential of alternative electricity supply infrastructures as constrained by innate physical limits. Coal-fired generation meets the criteria of longevity (abundance of energy source) and scalability (effective capability to expand to the multi-terawatt level) which are critical for a sustainable energy supply chain, but it carries a very heavy carbon footprint. Renewables and nuclear power meet both the longevity and climate friendliness criteria. However, they vary in terms of their ability to deliver net energy at a scale needed for meeting a huge global energy demand. The low density of renewable resources for electricity generation and the current intermittency of many renewables limit their ability to achieve high rates of growth. And a significant global increase in nuclear power deployment could engender serious risks related to proliferation, safety, and waste disposal. Unlike renewable sources of energy, nuclear power is an unforgiving technology because human lapses and errors can have ecological and social impacts that are catastrophic and irreversible. The transition to a low carbon economy is likely to prove much more challenging than some optimists have claimed.Energy Production and Transportation,Climate Change Mitigation and Green House Gases,Energy and Environment,Environment and Energy Efficiency,Energy Demand

Current and forthcoming issues in the South African electricity sector

One of the contentious issues in electricity reform is whether there are significant gains from restructuring systems that are moderately well run. South Africa's electricity system is a case in point. The sector's state-owned utility, Eskom, has been generating some of the lowest-priced electricity in the world, has largely achieved revenue adequacy, and has financed the bulk of the government's ambitious electrification program. Moreover, the key technical performance indicators of Eskom's generation plants have reached world-class levels. Yet the sector is confronted today with serious challenges. South Africa's electricity system is currently facing a tight demand/supply balance, and the distribution segment of the industry is in serious financial trouble. This paper provides a careful diagnostic assessment of the industry and identifies a range of policy and restructuring options to improve its performance. It suggests removing distribution from municipal control and privatizing it, calls for vertical and horizontal unbundling, and argues that the cost-benefit analysis of different structural options should focus on investment incentives and not just current operating efficiency.Energy Production and Transportation,Electric Power,Environment and Energy Efficiency,Energy and Environment,Infrastructure Economics

Regionalizing telecommunications reform in West Africa

In recent years, there has been an increasing recognition that significant welfare gains could be realized through deep forms of regional integration which entail harmonization of legal, regulatory and institutional frameworks. Reforms that reduce cross-border transaction costs and improve the performance of “backbone” infrastructure services are arguably even more important for the creation of an open, unified regional economic space than trade policy reforms narrowly defined. This paper assesses the potential gains from regionalized telecommunications policy in West Africa. To this end, the paper: (i) discusses how regional cooperation can overcome national limits in technical expertise, enhance the capacity of nations credibly to commit to stable regulatory policy, and ultimately facilitate infrastructure investment in the region; (ii) identifies trade-distorting regulations that inhibit opportunities for regional trade and economic development, and so are good candidates for regional trade negotiations to reduce indirect trade barriers; and (iii) describes substantive elements of a harmonized regional regulatory policy that can deliver immediate performance benefits.E-Business,Environmental Economics&Policies,ICT Policy and Strategies,Transport Economics Policy&Planning,Emerging Markets

Nuclear Power: Understanding the Economic Risks and Uncertainties, Energy Policy

a b s t r a c t This paper identifies the fundamental elements and critical research tasks of a comprehensive analysis of the costs and benefits of nuclear power relative to investments in alternative baseload technologies. The proposed framework seeks to: (i) identify the set of expected parameter values under which nuclear power becomes cost competitive relative to alternative generating technologies; (ii) identify the main risk drivers and quantify their impacts on the costs of nuclear power; (iii) estimate the nuclear power option value; (iv) assess the nexus between electricity market structure and the commercial attractiveness of nuclear power; (v) evaluate the economics of smaller sized nuclear reactors; (vi) identify options for strengthening the institutional underpinnings of the international safeguards regime; and (vii) evaluate the proliferation resistance of new generation reactors and fuel cycles. & 2010 Elsevier Ltd. All rights reserved. Motivation and context Volatile fuel prices, concerns about the security of energy supplies, and global climate change are coinciding to strengthen the case for building new nuclear power generation capacity. By 2030, global electricity demand is projected to more than double to over 30,000 TWh annually. More than 70% of the increased energy demand will come from developing countries, led by China and India. Providing sufficient energy to meet the needs of a growing world population with rising living standards will be a challenge. Doing it without substantially exacerbating the already disquieting risks of climate change will be an especially daunting task. There is an emerging consensus that there is no obvious ''silver bullet'' for addressing the global energy challenge-the solution will be comprised of a variety of technologies on both the supply and demand side of the energy system Proponents argue that in relation to the objectives of electricity supply security, resource efficiency, and mitigating the threat of climate change, nuclear power performs very well. Nuclear power: (a) represents a well-established technology for generating electricity that produces no carbon or other climaterelevant emissions; (b) is amenable to significant scaling-up and thus can provide large amounts of power; and (c) uses a natural resource (uranium), which is found at an abundance (2-3 parts per million) in the earth's crust-with advanced technologies, it could provide enough fuel to meet the world's electricity needs for several centuries. And, advances in nuclear reactor technology have substantially improved the underlying economics and safety profile of nuclear power. Skeptics claim that nuclear power is costly and technically complex. It involves the use of highly toxic materials that must be kept secure from attack or theft. Moreover, a viable technology for the permanent disposal or reprocessing of spent nuclear fuel has not yet been fully demonstrated. Finally, even in a carbon-constrained world, nuclear power may be less ARTICLE IN PRES

Market Concentration, Contestability, and Sunk Costs.

This paper provides an exploratory assessment of the theory of contestability that is based on a diverse sample of industries and introduces a new important determinant of market concentration. The results of the paper indicate that the variables determining the degree of contestability of markets are significant correlates of market concentration. Sunk costs account for a substantial portion of the sample variance of concentration even after technological factors are controlled for. Copyright 1990 by MIT Press.
