Empirical research on the relationship between market congestion and the market competitive level largely falsifies the positive relationship predicted by theoretical models. In this paper, I exploit the airline industry network structure and focus on the level of congestion during periods in...

How did the diffusion of the Internet affect performance and product quality in the airline industry? We argue that the shift to online distribution channels has changed the way airlines compete for customers - from an environment in which airlines compete for space at the top of travel agents'...

We approach the issue of the value of a platform to a seller in a two-sided market where both buyers and sellers multi-home. A seller that loses access to a major buyer platform can potentially incur substantial financial losses. We exploit a recent conflict between American Airlines and two...

We study how organizational boundaries affect pricing decisions using comprehensive data provided by a large U.S. airline. We show that contrary to prevailing theories of the firm, advanced pricing algorithms have multiple biases. To quantify the impacts of these biases, we estimate a structural...

In this article, we estimate the price elasticities of demand for subscription and consumer switching costs for mobile telephony. We use a panel of Portuguese consumer level data to estimate a series of multinomial and mixed logit models. The demand for subscription is elastic. Switching costs...

This article assesses the unilateral effects on prices of a merger in the Portuguese mobile telephony market. We use aggregate quarterly data from 1999 to 2005 and a nested logit model to estimate the price elasticities of demand and the marginal costs of subscription of mobile telephony. Given...

This paper uses a unique individual transactions data set to investigate the effects of internet purchase on the prices paid for airline tickets. The analysis also investigates the effects of changes in the percentage of online transactions on both online and offline prices and on price...

There is a substantial number of cases where the a priori relationship between products is not at all clear in the sense that although apparent to be clear substitutes may turn out to be in fact complements, or vice-versa. This paper aims to study the relationship between fixed and mobile...

We present experimental results from a series of sessions organized using the Power Market simulator; a software designed to realistically replicate the Spanish Electricity Market. In the experiments reported here we compare the status quo to two alternative treatments which represent...

We study a retail benchmarking approach to determine access prices for interconnected networks. Instead of considering fixed access charges as in the existing literature, we study access pricing rules that determine the access price that network i pays to network j as a linear function of the...
