On the Use of Double-Log Forms in Energy Demand Analysis

Andre Plourde and David Ryan

Year: 1985
Volume: Volume 6
Number: Number 4
DOI: 10.5547/ISSN0195-6574-EJ-Vol6-No4-8
View Abstract

Abstract:
The double-logarithmic demand function has been used widely in static energy demand studies. Recent examples include studies of electricity demand by Betancourt (1981) and Dias-Bandaranaike and Munasinghe (1983), of petroleum consumption by Brown (1983), and natural gas demand by Gowdy (1983). In this paper we examine some theoretical issues on the use of these functional forms in energy demand analysis and note a few related problems. Our analysis draws from the study by Dias-Bandaranaike and Munasinghe (1983) (hereafter DBM) recently published in The Energy Journal, Volume 4, Number 2. We concentrate on this paper for several reasons. First, it examines some of the theoretical underpinnings of double-log demand functions. Second, the authors claim that one of the contributions of their study is "[an] approach ... to derive demand functions [that] could be used to derive similar functions for other types of goods and services, besides electricity". Third, their study inadvertently reveals a number of problems that arise when the overriding concern is obtaining demand equations of the double-log form.



Special Feature U.S.-Canadian Trade Agreement: An Energy Colloquium

Philip K. Verleger, Jr., Leonard Waverman, Andre Plourde, Arlon R. Tussing, Henry Lee, Jean-Thomas Bernard

Year: 1988
Volume: Volume 9
Number: Number 4
DOI: 10.5547/ISSN0195-6574-EJ-Vol9-No4-6
View Abstract

Abstract:
The United States and Canada recently concluded a comprehensive agreement which calls for removing restrictions on trade between them, including energy. To explain the details of the energy portions of the agreement, we present by a series of comments by seven authors from both sides of the border. They deal with various energy sources (oil, gas, electricity and uranium) and with the situations peculiar to various geographic locations.

Natural Gas Trade in North America: Building up to the NAFTA

Andre Plourde

Year: 1993
Volume: Volume14
Number: Number 3
DOI: 10.5547/ISSN0195-6574-EJ-Vol14-No3-3
View Abstract

Abstract:
This paper traces the evolution of natural gas trade among Canada, Mexico, and the United States in the 1967-1992 period. In addition, the provisions of the North American Free Trade Agreement (NAFTA) that relate to natural gas trade are examined in the light of the corresponding aspects of the Canada-United States Free Trade Agreement (FTA). One of the main conclusions to emerge is that exports from Canada to the United States would likely continue to dominate North American natural gas trade patterns under the NAFTA. Past experience suggests that regulatory policies play a crucial role in determining trade patterns. In the case of Canada and the United States, the policies of deregulation implemented by the two countries prior to 1989 have proven to be much more important than has the FTA in encouraging cross-border trade in natural gas. Since the NAFTA allows Mexico to maintain a highly interventionist approach to energy policy, an internally-driven process of policy change will be required to liberalize natural gas trade between Mexico and the other parties to the Agreement. A few specific developments relating to natural gas trade among the NAFTA parties are also examined in the light of the Agreement.



On the Renewal of Concern for the Security of Oil Supply

Chantale LaCasse and Andre Plourde

Year: 1995
Volume: Volume16
Number: Number 2
DOI: 10.5547/ISSN0195-6574-EJ-Vol16-No2-1
View Abstract

Abstract:
It seems curious that the security of oil supply would again emerge as a source of concern precisely when oil market conditions seem to be most favourable to oil-importing nations. We trace this development to the increased import volumes that have followed the 1986 collapse in the world oil price, and argue that concerns over the source of oil are of primary importance only in situations where physical availability is likely problematic. As the conception of security of supply is broadened, a distinction between random and strategic shocks is useful. Supply-side considerations, such as stockpiles, seem apt only to address the consequences of random shocks. As time horizons lengthen, supply-side measures lose their effectiveness, and demand-side considerations emerge as possible means of dampening the macroeconomic effects of future strategic shocks. Implementation remains an unresolved issue: the expected costs and benefits of specific interventions must still be compared.



Oil Sands Royalties and Taxes in Alberta: An Assessment of Key Developments since the mid-1990s

Andre Plourde

Year: 2009
Volume: Volume 30
Number: Number 1
DOI: 10.5547/ISSN0195-6574-EJ-Vol30-No1-5
View Abstract

Abstract:
This paper examines oil sands royalty and tax systems that have either been proposed or implemented since the mid-1990s. Simulation models of oil sands production projects are constructed and the distribution of ex ante economic rents for various assumed crude oil price paths is calculated. The results suggest that until 2007 changes in royalties and taxes had been favorable to producers. The pattern of estimated real internal rates of return obtained through the simulations supports this conclusion. The recommendations of the provincially appointed Royalty Review Panel were anchored in the view that Alberta�s oil sands industry had matured since the mid-1990s and that a distribution of ex ante rents more favorable to Albertans, as owners of the resource, was thus warranted. In contrast, the changes proposed by the Government of Alberta in 2007 would effectively return the distribution of ex ante rents to what prevailed a decade earlier. However, the role of royalties (as opposed to corporate income tax) as means of capturing rents for governments is more important under the proposals made in 2007.
