In the context of supply function competition with private information, we test in the laboratory whether — as predicted in Bayesian equilibrium — costs that are positively correlated lead to steeper supply functions and less competitive outcomes than do uncorrelated costs. We find that the...

In a laboratory experiment with supply function competition and private information about correlated costs we study whether cost interdependence leads to greater market power in relation to when costs are uncorrelated in the ways predicted by Bayesian supply function equilibrium. We find that...

This paper considers cost-reducing R&D investment with spillovers in a Cournot oligopoly with overlapping ownership. We show that overlapping ownership leads to internalization of rivals' profits by firms and find that, for demand not too convex, increases in overlapping ownership increase...

The liberalization of the electricity sector increases the need for realistic and robust models of the oligopolistic interaction of electricity firms. This paper compares the two most popular models: Cournot and the Supply Function Equilibrium (SFE), and tests which model describes the observed...

This paper considers cost-reducing R&D investment with spillovers in a Cournot oligopoly with overlapping ownership. We show that overlapping ownership leads to internalization of rivals profits by firms and find that, for demand not too convex, increases in overlapping ownership increase...

We examine the effects of overlapping ownership in a Cournot oligopoly with free entry. If firms develop overlapping ownership only after entering, then an increase in the degree of overlapping ownership spurs entry but causes price to increase and total surplus to fall. Also, entry is never...

We develop a tractable general equilibrium framework in which firms are large and have market power, with respect to both products and labor, and in which a firm's decisions are affected by its ownership structure. We characterize the Cournot--Walras equilibrium of an economy where each firm...

This paper sets up a general oligopolistic equilibrium model with unionized labor markets. By accounting for productivity differences, the model features pro t and wage differentials across industries. We use this setting to study the impact of trade liberalization on employment, welfare, and...

This paper sets up a general oligopolistic equilibrium model with two countries that differ in the centralization of union wage setting. Being interested in the consequences of openness, we show that, in the short-run, trade increases welfare and employment in both locations, and it raises...
