We present a model in which the consumers' capacity to access a service provided on a network depends negatively on the price charged by the network owner per capacity unit. Several scenarios concerning the structure of the downstream service provision market are studied. First, a monopolist...

Two retailers operate in a monopsonistic, oligopolistic environment. They have to buy from spatially dispersed suppliers and use uniform pricing downstream. We characterize prices and location in the two-stage location-then-price game under two different pricing policies in the upstream market:...

One of the most challenging problems to applied industrial economists is the detection of colluding behavior in oligopolistic markets. In this paper we postulate how low market share variability may be used as a primary indicator of cartel success to maintain the agreed upon levels of...

In the context of the recent electricity market reforms in Europe and the US, we evaluate the performance of the Spanish pool. Our method is not based on price-cost estimates but rather on the different behavior of operators with higher market power as compared to the behavior of more...

We study culture and risk aversion as causes of gender differences in ultimatum bargaining. It has often been conjectured in the literature that gender differences in bargaining experiments are partly due to differences in risky decision making. Using the data obtained from our experimental...

Using data obtained from experiments reported in García-Gallego (1998) and García- Gallego and Georgantzís (2001), we estimate a simple model of adaptive behavior which could describe pricing in a market whose demand conditions are unknown to the firms. Divergence between the limit of...
