We consider an empirical estimation of the Environmental Kuznets Curve (EKC) for carbon dioxide and sulphur, with a focus on confidence set estimation of the tipping point. Various econometric – parametric and nonparametric – methods are considered, reflecting the implications of...

We consider a firm that must undergo a costly and time-consuming regulatory process before making an irreversible, lagged investment whose value varies randomly. We analyze two cases: regulatory approval is valid forever or it expires after some time. We apply our model to Hydro-Québec's...

L'industrie de l'électricité subit une restructuration à l'échelle mondiale. La concurrence est introduite au niveau de la production alors que le transport et la distribution demeurent des monopoles réglementés par les gouvernements. Aux États-Unis, il y a déjà ouverture du marché de...

We develop a model in which two firms from different countries compete on each other domestic market. Each firm is jointly owned by the residents and the government of its country. The extent of the government's stake in the public enterprise is endogenous and it determines the weight given to...

Vertical integration occurs when a transaction between two consecutive stages of production is carried through an internal organisation rather than the market. For most mineral products that are found in Canada, we can observe a fairly high degree of vertical integration from exploration up to...

Hydro-Quebec's electricity rates within its mandated territory increased at the annual rate of 3.8% from 1980 to 1990 despite the fact that there was no growth in the first three years. The government-owned enterprise is rather pessimistic with respect to the expected electricity demand growth...

This paper surveys the changes since 1972 in the federal tax laws applicable to the Canadian mining industry. Using a partial equilibrium model, we analyse the effect of these changes on the relative prices of the factors of production used by the mining firm. Changes in the provincial tax...

The authors test the statistical significance of Pindyck’s (1999) suggested class of econometric equations that model the behaviour of long-run real energy prices. The models postulate meanreverting prices with continuous and random changes in their level and trend, and are estimated using...

Fluctuations in the prices of various natural resource products are of concern in both policy and business circles; hence, it is important to develop accurate price forecasts. Structural models provide valuable insights into the causes of price movements, but they are not necessarily the best...

À cause du cadre réglementaire et des politiques gouvernementales qui s'appliquent à la demande d'énergie, celle-ci a reçu beaucoup d'attention de la part des développeurs de modèles. Dans cet article, je présente un modèle intégré de la demande totale d'énergie. Les principaux...
