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,...

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

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...

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...

A long-standing question in biology and economics is whether individual organisms evolve to behave as if they were striving to maximize some goal function. We here formalize the \as if" question in a patch-structured population in which individuals obtain material payoffs from (perhaps very...

In this paper, we evaluate the impact of foreign fees, paid by consumers when they withdraw cash at banks that are not their own, on their withdrawals. We take advantage of a natural experiment whereby (non linear) payment fees for withdrawing cash at foreign ATMs were introduced at one point in...

We study the political determination of the level of social long-term care insurance when voters also choose private insurance and saving amounts. Agents di§er in income, probability of becoming dependent and of receiving family help. Social insurance redistributes across income and risk...
