Toward an Optimal Oil and Gas Leasing System

Walter J. Mead

DOI: 10.5547/ISSN0195-6574-EJ-Vol15-No4-1View Abstract

Abstract:
The four principal leasing systems-work program, royalty, profit share (including rent resource tax), and bonus bidding are reviewed relative to their efficiency in maximizing and collecting the present value of economic rents. Empirical research is shown to support theoretical conclusions that the most efficient system appears to be bonus bidding, without a fixed royalty, with leases issued in perpetuity, with environmental and other regulations required to pass a benefit/cost test, and with elimination of any nationalistic or other barriers to entry.




Macroeconomic Responses to Oil Price Increases and Decreases in Seven OECD Countries

Knut Anton Mork, Oystein Olsen, and Hans Terje Mysen

DOI: 10.5547/ISSN0195-6574-EJ-Vol15-No4-2View Abstract

Abstract:
The correlations between oil-price movements and GDP fluctuations are investigated for the United States, Canada, Japan, Germany (West), France, the United Kingdom, and Norway. The responses to price increases and decreases are allowed to be asymmetric. Bivariate correlations as well as partial correlations within a reduced-form macroeconomic model are considered. The correlations with oil-price increases are negative and significant for most countries, but positive for Norway, whose oil-producing sector is large relative to the economy as a whole. The correlations with oil-price decreases are mostly positive, but significant only for the United States and Canada. Most countries show evidence of asymmetric effects, with Norway again as an exception.




Price Convergence Across Natural Gas Fields and City Markets

W. David Walls

DOI: 10.5547/ISSN0195-6574-EJ-Vol15-No4-3View Abstract

Abstract:
This research reports the results of cointegration tests between natural gas spot prices at various production fields, pipeline hubs, and city markets. Cointegration between prices is evidence that spatial arbitrage is enforcing tile law of one price across market locations. The results show that prices at certain city markets, Chicago and to a lesser went California, are cointegrated with prices at field markets. However, the prices at most other locations do not move in step with gas prices in the field markets. Customer access to pipeline transportation, or competitive bypass, may explain why prices at some city markets are more responsive to production field prices than others.




Fuel Efficiency and Automobile Safety: Single-Vehicle Highway Fatalities for Passenger Cars

J. Daniel Khazzoom

DOI: 10.5547/ISSN0195-6574-EJ-Vol15-No4-4View Abstract

Abstract:
This paper reports the results of an effort to shed some light on the relationship that might exist between enhanced standards and single-vehicle passenger car highway fatalities. Quantification of this relationship is not an easy task Not surprisingly, the literature on modeling the relationship between fuel economy and highway fatalities is very scant. Our analytic framework consists of two submodes: a corporate average fuel economy (CAFE) submodel and a single-vehicle highway fatalities submodel. Some of the variables that enter the CAFE relationship affect single vehicle fatalities, as well. The results of this study are not unequivocal in every respect. However, they indicate that enhanced standards and automobile safety need not be at odds with each other.A main message that emerges from this study is the need not to confuse car downsizing with downweighting. Quantitative studies of highway fatalities have mostly treated weight and size interchangeably, and have used only the weight variable in the fatalities equation to avoid dealing with multicollinearity. Such references as "size/weight' which lump size and weight together as if they were the same variable are not uncommon in the safety literature. Our study indicates that weight and size are not a proxy to each other, and that in single vehicle crashes they are likely to have opposite effects on safety. Men researchers choose to drop the size variable and include only the weight variable in the fatalities equation, the weight estimate may end up with a negative sign, not necessarily because weight has a beneficial effect on safety., but because the omitted size variable has a dominant beneficial effect on safety, which is picked up by the weight variable that appears in the equation.




Income Distribution Effects of Electric Utility DSM Programs

Ronald J. Sutherland

DOI: 10.5547/ISSN0195-6574-EJ-Vol15-No4-5View Abstract

Abstract:
This paper uses the Residential Energy Consumption Survey undertaken by the Energy Information Administration in 1990 to estimate the statistical association between household income and participation in electric utility energy conservation programs and the association between participation and the electricity consumption. The results indicate that utility rebates, energy audits, load management programs and other conservation measures tend to be undertaken at greater frequency by high income households than by low income households. Participants in conservation programs tend to occupy relatively new and energy efficient residences and undertake conservation measures other than utility programs, which suggests that utility sponsored programs are substitutes for other conservation investments. Electricity consumption during 1990 is not significantly less for households participating in utility programs than for nonparticipants, which also implies that utility conservation programs are displacing other conservation investments. Apparently, utility programs are not avoiding the costs of new construction and instead are transferring wealth, particularly to high income participating households.




Cost-Effective Climate Policy in a Small Country

Cathrine Hagem

DOI: 10.5547/ISSN0195-6574-EJ-Vol15-No4-6View Abstract

Abstract:
Unilateral action to curb CO2 emissions in a small country or a group of countries has only a limited effect on global CO2 emissions. However, it could be a first step toward a broader climate treaty. So far, unilateral commitments have been aimed at reducing national consumption of fossil fuels. A country that produces and consumes fossil fuels can also influence the global CO2 emissions by reducing its production. The estimated cost of reducing national CO2 emissions in Norway, through a reduction in fossil fuel consumption, is presented in a report from the Environmental Tax Committee (1992). In this paper, that cost is compared with an estimated cost of reducing fossil fuel production. The calculation reveals that it could be less costly to reduce the production than the consumption, given that the effect on global CO2 emissions is identical.




Incomplete International Climate Agreements: Optimal Carbon Taxes, Market Failures and Welfare Effects

Rolf Golombek and Jan Braten

DOI: 10.5547/ISSN0195-6574-EJ-Vol15-No4-7View Abstract

Abstract:
This paper provides an empirical study of optimal carbon taxes and welfare effects under incomplete international climate agreements when there are market failures in the cooperating countries. The objective of the group of countries taking part in the international climate agreement is to design carbon taxes that maximize their aggregate net income, subject to a constraint on global CO2 emissions. We use a numerical energy model to study scenarios that differ with respect to types of CO2 taxes and countries taking part in the climate agreement. We also discuss the impact on regional net income following from different international climate agreements.




Rethinking Contracts for Purchasing Power: The Economic Advantages of Dispatchability

Gary W. Dorris and Timothy Mount

DOI: 10.5547/ISSN0195-6574-EJ-Vol15-No4-8View Abstract

Abstract:
The purpose of this article is to evaluate and compare the incremental cost of purchased power from non-utility generators (NUG) versus utility built generation considering a variety of contracts for energy purchases. Four types of contracts are evaluated: (1) Flat Rate Produce and Pay, (2) On-Peak/Off-Peak, (3) Basic Dispatchable, and 4) Actual Cycle Energy Dispatch. An analysis conducted for a representative utility calculates the effects of NUG power purchases on a utility's energy production costs and the cost of new debt issuances. Dispatchable energy contracts are shown to provide significant economic and operating advantages over Flat Rate and On-Peak/Off-Peak energy contracts. The analysis also shows that NUG purchases based on the actual costs of dispatch cost less than utility built generation financed at the utility's weighted average cost of capital. NUG contracts for a utility which already has significant risk exposure are shown to parallel a capital lease. Under these conditions, additional payment obligations to NUGs increase the cost of new debt issuances making an equity issuance for utility built capacity a more attractive option.




Reactive Power is a Cheap Constraint

Edward Kahn and Ross Baldick

DOI: 10.5547/ISSN0195-6574-EJ-Vol15-No4-9View Abstract

Abstract:
Hogan (1993) has proposed a version of marginal cost pricing for electricity transmission transactions that include a component for reactive power to support voltage at demand nodes. His examples support the notion that the cost of satisfying voltage constraints can be quite high. We show that in his simplest example the price on this constraint results from an uneconomic and artificial characterization of the problem, namely an inefficient and unnecessarily constrained dispatch. By eliminating this characterization, the price of reactive power falls to a very modest level. Our counterexample has implications for the institutional arrangements under which transmission pricing reform will take place. We believe that environment will be an open access competitive setting, where dispatch is still controlled by one group of participants. Manipulation of marginal transmission costs becomes quite feasible in complex networks through subtle changes to dispatch. Therefore an open access regime using marginal cost pricing must involve either some kind of monitoring and audit function to detect potential abuses, or alternatively, institutional restructuring to eliminate conflicts of interest.




A Dynamic Model of Industrial Energy Demand in Kenya

Semboja Haji Hatibu Haji

DOI: 10.5547/ISSN0195-6574-EJ-Vol15-No4-10View Abstract

Abstract:
This paper analyses the effects of input price movements, technology changes, capacity utilization and dynamic mechanisms on energy demand structures in the Kenyan industry. This is done with the help of a variant of the second generation dynamic factor demand (econometric) model. This interrelated disequilibrium dynamic input demand econometric model is based on a long-term cost function representing production function possibilities and takes into account the asymmetry between variable inputs (electricity, other-fuels and labour) and quasi-fixed input (capital) by imposing restrictions on the adjustment process. Variations in capacity utilization and slow substitution process invoked by the relative input price movement justifies the nature of input demand disequilibrium. The model is estimated on two ISIC digit Kenyan industry time series data (1961 - 1988) using the Iterative Zellner generalized least square method.
