DEFINING A RIGHT OF ACCESS TO INTERSTATE NATURAL GAS PIPELINES

Decontrol of the wellhead price of natural gas under the Natural Gas Policy Act of 1978 ended the general shortage of natural gas, which had begun in the 1960s. It also led to dislocations in gas markets because of regulatory uncertainties that created difficulties in renegotiating contracts made during the shortage period. Together, the decontrol and dislocations led to a decline in the traditional role of interstate gas pipelines as full-requirements suppliers to local distributors, who now use pipelines primarily as transporters of gas purchased independently of the pipelines. The growth in transport transactions has increased greatly the potential scope of efficient exchanges in gas markets. Achieving efficiency gains, however, requires an underlying right of access to pipelines that is non-discriminatory, exchangeable, and consistent with both existing regulation and pre-existing contractual relationships. The authors define such a right, which they call exchangeable transport entitlement (ETE). They show that ETE satisfies the criteria for efficiency gains, and they examine the practical problems of the transition that a regulatory regime incorporating ETE faces. The analysis has important implications for other industries and for the economic theory of regulation. Specifically, the analysis shows that economists must realize the importance of diverse contractual relationships in both their theoretical literature and their proposals for regulatory reform.     

Wage Structures in the Private and Public Sectors in West Germany

In this paper, we investigate pay structures in the private and public sectors for West Germany. We commence by describing some basic features of the public sector. We use micro-data from the German Socio-Economic Panel for the years 1984–93 to analyse developments and differences in public and private sector wage distributions for both males and females. We break wages down into different education groups and age-groups, and use regressions to construct conditional wage differentials. Our results differ in many aspects from findings for the UK. For instance, we find that although mean wages are higher in the public sector for both males and females, conditional wages are higher in the private sector for all education groups for males, but higher in the public sector for females. JEL classification: J3.     

Why a New Journal?

Speaking both personally and officially, I am delighted to salute the appearance of this first issue of Industrial Relations: A Journal of Economy and Society. Since my service as the first Director of the Institute of Industrial Relations at Berkeley, I have retained a close personal attachment to the Institute and a sense of pride in its growing record of accomplishment. And because I am a student in the industrial relations field, I can speak with some personal conviction of the great need for this type of publication. As President of the University of California, I am pleased to see this new venture undertaken by the Institute of Industrial Relations, one of the University’s many important research and service organizations. The publication of new knowledge, insight, and scholarly speculation is an essential part of the advancement of learning. The free marketplace of ideas cannot operate effectively without the avenues of communication provided by the scholarly journals which serve every field of research. I am sure that Industrial Relations will prove a stimulating vehicle for the exchange and development of ideas about a highly significant segment of modern industrial society.     

CONSERVED ENERGY SUPPLY CURVES FOR U.S. BUILDINGS

Comparison of nine conservation supply curves for electricity shows that fully implementing a series of energy efficiency measures will result in annual saving of 734 billion kWh (BkWh). This is 45 percent of 1989 U.S. building sector electricity use of 1627 BkWh and represents a $29 billion saving. When translated to units of conserved carbon dioxide (CC CO₂), this annual saving is 514 megatonnes, which is 10 percent of the total 1989 U.S. carbon dioxide (CO₂) emissions from all sources. Implementing additional fuel efficiency measures would result in further potential saving of 5·2 quads of fuel (natural gas and oil) per year, or another 300 megatonnes of CO₂, at a net savings of $20 billion. Fuel switching (replacing electric resistance heat with on-site natural gas combustion) would produce annual saving of another 74 megatonnes of CO₂ at a net saving of $6·8 billion. Thus, total CO₂ saving from these combined efficiency measures are 890 megatonnes at a net saving of $56 billion per year.     

The Net Benefits to Leverage

I estimate the market's valuation of the net benefits to leverage using panel data from 1994 to 2004, identified from market values and betas of a company's debt and equity. The median firm captures net benefits of up to 5.5% of firm value. Small and profitable firms have high optimal leverage ratios, as predicted by theory, but in contrast to existing empirical evidence. Companies are on average slightly underlevered relative to the optimal leverage ratio at refinancing. This result is mainly due to zero leverage firms. I also look at implications for financial policy.
