Firm/interruptible gas pricing patterns in a regulated environment

Conclusion This study provides empirical tests for the effects of rate base regulation, curtailment priorities, fuel clauses, and elected commissioners on firm/interruptible gas pricing patterns. These regulations do alter observed pricing patterns with curtailment priorities, fuel clauses, and elected commissioners all producing net social gains. Rate of return regulation imposes social costs resulting in a net decrease in social welfare. Ignoring the political influences upon regulators, regulation generally encourages consumption at the peak relative to the off-peak. Nonetheless, overall social welfare is improved if all four types of regulatory characteristics are present, since most rates are reduced from their monopoly levels.     

Gas Utility Prices in a Restructured Industry

The natural gas industry has witnessed significant policy changes since 1978. The Federal Energy Regulatory Commission has undertaken a number of policy initiatives designed to promote competition in the natural gas industry. These initiatives have affected both natural gas pipeline and local gas distribution companies. This study provides an empirical examination of the impact of restructuring on local gas distribution utilities' residential, commercial, and industrial prices.     

Does globalization weaken labor unions in developing countries?

For a developing economy with a given urban wage rate, globalization in capital markets strengthens labor unions. This result hinges on the fixed urban wage rate, which leads to a constant capital–labor ratio in the urban sector. Globalization via capital inflows not only enhances the employment effect of unionization but also reduces the rent-shifting related loss in production inefficiency to domestic capital, lending a support to labor unions for developing economies. This result is contrary to the common belief that labor unions tend to be weakened during the globalization process observed after 1980s in many developed economies.     

An estimation of the deadweight and x-efficiency losses in the municipal electric industry

This article examines X-efficiency gains from competition (duepoly) in the municipal electric industry. Empirical analysis is conducted through estimation of monopoly and duepoly long run marginal cost. Inefficiencies are manifested primary through increased marginal cost of nonproduction operations. Empirical results indicate that other studies may have significantly underestimated the total losses from monopoly. However, most of the gains from competition pressure are nonallocative. Thus, interest in public policies designed to increase competitive preassure may depend upon whether the objective is allocative efficiency, redistribution of income, or both.     

A data envelopment analysis of gas utilities' efficiency

This study examines the Natural Gas Policy Act of 1978 and Federal Energy Regulatory Commission (FERC) policies that culminated in Order 636 in 1992. The regulatory environment in which natural gas distribution utilities operate was altered. FERC policies forced local gas distribution utilities into an increasingly competitive environment. Restructuring of the industry may affect economic efficiency. Data Envelopment Analysis is used to examine the economic efficiency of gas distributors during 1975–94. Federal policy appears to lead to a reduction in scale due to restructuring and more competition. Reduced scale economies have not altered the economic efficiency of the utilities.     

Impact of regulation on vertical integration in the electric industry

The purpose of this paper is to determine the factors which affect electric utilities’ dicisions about whether to vertically integrate into coal. Specifically, we attempt to determine whether variation in the stringency of regulation will affect the probability of vertically integrating. Public Service Commissions allow, to one degree or another, utilities to pass along fuel adjustment charges to customers. Other factors equal, we hypothesize that the larger the fuel adjustment charge allowed per KWH, and the less stringent the PSC’s regulaton of transfer pricing of fuel, the higher will be the probability of vertically integrating into coal to capture rents. A maximum likelihood logit model is specified and estimated; strong support is offered for the theory.     

Urban development,excessive entry of firms and wage inequality in developing countries

This paper examines the short and long-term effects of urbanisation, via favourable urban development policies, on income distribution and social welfare for a developing country, in which the urban manufacturing sector is characterised by imperfect competition and free entry. Urbanisation shifts rural workers to the highly productive urban sector, while causing production in urban firms to expand because of scale economies. However, urbanisation may worsen wage inequality between skilled and unskilled labour in the short term. In the long term, urbanisation can attract new firms to the urban sector and favourable urban development policies may result in excessive entry of firms, which can amplify wage inequality in the economy. This entry-amplifying effect is confirmed empirically, especially for low and lower-middle-income countries. If the entry effect is not considered, the impact of urbanisation on wage inequality could be understated by 13% for low and lower-middle-income countries.     

Downstream gas pricing in an era of upstream deregulation

State public service commission regulation of gas utility pricing is examined during the period of wellhead price deregulation. A model which incorporates asymmetry in price setting during a period of changing input costs is estimated. Statistical analyses suggest public service commission regulation slowed the increase in gas utility prices during periods of rising costs. Gas utility pricing was not monitored as closely when purchased gas prices fell, thereby altering the rate structure in favor of industrial customers. Federal Energy Regulatory Commission policies designed to promote competition by restructuring the transmission sector of the gas industry after 1985 appear to have suppressed retail prices in industrial markets.     

An examination of the relative economic efficiency of mutual vs. stock savings institutions

This article employs a nonlinear system of Cobb-Douglas profit and input demand equations to analyze price and technical efficiency in a sample of presumably not-for-profit mutual and presumably profit-maximizing stock savings institutions. Theories of property rights and agency are reviewed to provide predictions of price efficiency (i.e., profit maximization and cost minimization behavior), and technical efficiency. The study makes several contributions to the literature. First, it examines the effect of ownership form on both price and technical efficiency. Second, it separately examines the effect of regulatory form on both price and technical efficiency. The model enables us to analyze the separate effects of ownership and regulatory form across a heterogeneous sample of firms. We also analyze the effects of risk in the form of two separate regulatory variables and the effect of market share on economic efficiency.     

An examination of the economic efficiency of class I railroads: A profit function analysis

This paper uses a system of translog profit and input demand equations to analyze price and technical efficiency in Class I railroads for the period 1978–1983. The results indicate that railroads are neither profit maximizers nor cost minimizers, that capital expenditures increase technical efficiency, and that deregulation led to greater economic efficiency. The average length of haul is negatively related to economic efficiency; track miles are negatively related to economic efficiency, market share positively affects economic efficiency; and, the ratio of freight to total revenue positively affects economic efficiency.
