The Effectiveness of Canadian Oil- and Gas-Pipeline Price Regulation 1976–82

This paper examines the effectiveness of the oil and gas-pipeline price-regulation system in Canada during the seven years beginning January 1976. Results for a threefold analysis are reported. When the seven-year period was considered as a whole, the regulatory system was not found to be ineffective in implementing the “comparable-earnings” and “capital-attraction” criteria. This finding also holds for the pre-October 1980 National Energy Plan-announcement period. The regulatory system was not effective, however, in achieving its proclaimed goals on a yearly basis. The “consumer-protection” hypothesis could not be rejected for the Canadian oil and gas-pipeline regulatory system. Résumé Ce mémoire examine l'efficacité de la réglementation relative aux prix d'utilisation des gazoducs et oléoducs au Canada sur une période de sept ans à partir de janvier 1976. Les résultats de cette analyse comportent trois volets. Si l'on tient compte globablement des sept années qui sont évaluées, la réglementation ne se montre pas inefficace du point de vue des profits comparatifs et de la facilité d'obtention de capitaux. Ces résultats s'appliquent à la période précédant la mise en vigueur de la Politique énergétique nationale en octobre 1980. Cependant, la réglementation n'atteint pas les objectifs fixés. L'hypothèse de protection du consommateur ne pouvait ětre rejetée dans le cas de la réglementation relative aux prix d'utilisation des gazoducs et oléoducs au Canada.     

The Geopolitics of Neighbourhood: Jerusalem’s Colonial Space Revisited

This article will focus on an ongoing process of Jerusalem’s contested urban space during the last decade namely the immigration of Palestinians, mostly Israeli citizens, to “satellite neighbourhoods”, i.e. Jerusalem’s colonial neighbourhoods that were constructed after 1967. Theoretically, this paper attempts to discuss neighbourhood planning in contested cities within the framework of geopolitics. In more details, we will focus on the relevance of geopolitics to the study of neighbourhood planning, by which we mean not merely a discussion of international relations and conflict or of the roles of military acts and wars in producing space. Rather, geopolitics refers to the emergence of discourses and forces connected with the technologies of control, patterns of internal migrations by individuals and communities, and the flow of cultures and capital.     

Envy and Altruism: Contrasting Bivariate and Univariate Prospect Preferences

We compare prospect ordering with and without envy and altruism. We find that envy can induce a violation of the univariate first‐degree stochastic dominance (FSD), and thus a violation of the classic expected utility monotonicity axiom. Surprisingly, altruism can also violate FSD preferences. The intuitive explanation of the result in the case of altruism hinges on the sign of the mixed derivative of the bivariate preference: the individual might prefer a certain correlation between her wealth and her peer group's wealth, and is therefore willing to violate FSD as long as the outcomes of the two parties are ordered according to her preferences. When investments are considered, envy and altruism can distort not only preferences but also actual choices.     

Mean-Gini analysis of stochastic externalities: The case of groundwater contamination

The mean-Gini approach is used to analyze stochastic externalities generated by agricultural production. The model addresses the problem of groundwater pollution caused by excessive fertilizer application. Inherent in the mean-Gini approach to expected utility maximization is a two-fold value: the simplicity of the two-parameter mean-variance model and satisfaction of necessary and sufficient conditions for stochastic dominance. Price and quantity policy recommendations to control externalities are formulated based upon the relative assessment of uncertainty by the regulatory authority and the farmers. Using the Gini as a measure of risk allows for the quantification of control policy measures under differentiated risk aversion and multiple sources of pollution. The model shows that when producers underestimate uncertainty, quota policies restricting fertilizer are more efficient than tax policies in reducing groundwater contamination.Work on this paper was carried out when visiting the University of Maryland. Financial aid for the work was provided by the USDA ERS-NRED under a cooperative agreement between the Department of Agricultural and Resource Economics, University of Maryland, and the USDA — Economic Research Service — Natural Resource Economics Division, I am grateful to John Miranowski and Darrell Hueth for that support. I am indebted as well to Lana Shalit, who helped me revise the paper.     

Price taking behavior and trading in options

Equilibrium prices of options are arbitrage prices in economies in which prices are determined endogenously and all agents are price takers. This paper shows that the price taking assumption in options' markets is unreasonable because a small agent can make huge gains by not being a price taker.     

Strategic Trading, Liquidity, and Information Acquisition

We study endogenous liquidity trading in a market with long-livedasymmetric information. We distinguish between public information,tractable information that can be acquired, and intractableinformation that cannot be acquired. Besides information asymmetryand noise, the adverse-selection spread depends on the diffusionof intractable information and on the interest rate. With endogenousliquidity trading, efficiency is lower than that implied bynoise-trading models. Liquidity traders benefit from the informationreleased through the insider's trades in spite of their monetarylosses. We study factors that affect the insider's informationacquisition decision, including the amount of intractable information,observability, and information acquisition costs.     

Dealership market: Market-making with inventory

This study considers the problem of a price-setting monopolistic market-maker in a dealership market where the stochastic demand and supply are depicted by price-dependent Poisson processes [following Garman (1976)]. The crux of the analysis is the dependence of the bid-ask prices on the market-maker's stock inventory position. We derive the optimal policy and its characteristics and compare it to Garman's. The results are shown to be consistent with some conjectures and observed phenomena, like the existence of a ‘preferred’ inventory position and the downward monotonicity of the bid-ask prices. For linear demand and supply functions we derive the behavior of the bid-ask spread and show that the transaction-to-transaction price behavior is intertemporally dependent. However, we prove that it is impossible to make a profit on this price dependence by trading against the market-maker. Thus, in this situation, serially dependent price-changes are consistent with the market efficiency hypothesis.
