Recent high natural gas prices have focused attention on competition in European gas markets. In response to anti-trust pressures, many long-term pipeline gas contracts in Europe have shifted from oil-linked indexation to pricing based on traded European gas hub indices. In this short paper I...

Building on a model of the interaction of risk-averse frms that compete in forward and spot markets, we develop an empirical strategy to test whether oligopolistic frms use forward contracts for strategic motives, for risk-hedging, or for both. An increase in the number of players weakens the...

Europe's dependence on Russian gas imports has been the subject of increasing political concern after gas conflicts between Russia and Ukraine in 2006 and 2009. This paper assesses the potential impact of Russian unreliability on the European gas market, and how it affects European gas import...

Three decade ago, federal policymakers - Republicans and Democrats - embarked on a general strategy of deregulation in the electricity, gas delivery, and telecommunications industries. The strategy called for restructuring to separate production from the transmission and distribution, followed...

This paper characterizes the Nash equilibrium in a pay-as-bid (discriminatory), divisible-good, procurement auction. Demand by the auctioneer is uncertain as in the supply function equilibrium model. A closed form expression is derived. Existence of an equilibrium is ensured if the hazard rate...

In most wholesale electricity markets generators must submit step-function offers of supply to a uniform price auction, and the market is cleared at the price of the most expensive offer needed to meet realised demand. Such markets can most elegantly be modelled as the pure-strategy, Nash...

This paper explores the implications of price-dependent demand in spatial models of product differentiation. We introduce consumers with a quasi-linear utility function in the framework of the Salop (1979) model. We show that the so-called excess entry theorem relies critically on the assumption...

In the homogenous good case, the relationship between market structure and efficiency was studied extensively. Assuming a standard quadratic utility with quantity competition, this paper carries on the analysis in a differentiated good context. It can be shown that there is a positive...
