This article examines how …rms facing volatile input prices and holding some degree of market power in their product market link their risk management and their production or pricing strategies. This issue is relevant in many industries ranging from manufacturing to energy retailing, where risk...

This article examines imperfectly competitive investment in electric power generation in the presence of congestion on the transmission grid. Under simple yet realistic assumptions, it precisely derives the technology mix as a function of the capacity of the transmission interconnection. In...

This article is the first to examine electric power producers' investment decisions when com- petition is imperfect and the transmission grid congested. This analysis yields numerous original insights. First, congestion on the grid is transient, and may disappear when demand is highest. Second,...

Price caps are often used by policy makers to "regulate markets". Previous analyses have focussed on the "supply side" impact of these caps, and derived the optimal price cap, which maximizes investment and welfare. This article expands the analysis to include the "demand side" impact of price...

This article formally analyzes the causes of underinvestment in electric power generation, and the various corrective market designs that have been proposed and implemented. It yields four main analytical findings. First, using a simple numerical example, (a linear demand function, calibrated on...

The advent of "smart meters" will make possible Real Time Pricing of electricity: customers will face and react to wholesale spot prices, thus consumption of electric power will be aligned with its opportunity cost. This article determines the marginal value of a fraction of demand (or a...

This paper develops a dynamic risk management model to determine a firm's optimal risk management strategy. The risk management strategy has two elements: first, until leverage is very high, the firm fully hedges its operating cash how exposure, due to the convexity in its cost of capital. When...

Using an exhaustive database on academic publications in mathematics, we study the patterns of productivity by world mathematicians over the period 1984-2006. We uncover some surprising facts, such as the absence of age related decline in productivity and the relative symmetry of international...
