By studying average variable costs, researchers examining the California energy crisis were sure to find examples of market power - even if that power may not have existed.

Several interconnected power systems worldwide have largely thermal and hydro production along with carbon cap-and-trade (C&T) systems and variable renewable energy sources (VRES). C&T policies increase VRES generation, and socially optimal storage deployment could integrate VRES output....

Although market concentration is one of the main impediments to productivity growth globally, data constraints have limited its analysis to developed countries or cross-country studies based on definitions of market concentration across nations and industries. This paper takes advantage of a...

In this paper we examine whether foreign banks presence has helped reduce concentration in the Indian banking market and thus increased competition among banks. Concentration has been measured using the Herfindahl-Hirschman Index of concentration and regressed on a set of explanatory variables...

Over their two years of existence since deregulation began, the electricity markets operated by the California Power Exchange [PX] and Independent System Operator [ISO] have often seen wide price fluctuations and numerous episodes of prices clearly above marginal costs of generation. Both...

In this article I develop a model of an infinitely repeated procurement auction with one buyer and several sellers. The buyer can accumulate a backlog of unfilled orders which, similar to a boom in demand, forces the sellers to collude on a low price to prevent undercutting. If the buyer's cost...

The Panzar-Rosse H statistic is a commonly used measure of market power in banking. It is widely believed that H0 is inconsistent with significant market power. The theoretical part of this study rigorously disproves this perception. Instead, the possibility of H0 under conditions of substantial...
