This paper links empirical literature on the use of price as an entry deterring mechanism with literature on the effect of multi-market contact on competition. The analysis uses a dataset of cable TV system prices to provide evidence that incumbent cable TV firms use price to deter entry by...

We consider some two dynamic models of entry in mobile telephony, with and without strategic pricing, and taking into account market penetration at entry, locked-in consumers and tariff-mediated network externalities. We show that on/off-net differentials may reduce the possibility of entry if...

The literature on information aggregation predicts that market growth unambiguously reduces uncertainty about the value of traded goods. The results were developed within the classical model, which assumes that traders’ values for the exchanged good are determined by fundamental (common)...

As online information availability for products and services is increasing and as buyers engage in more online search prior to purchase decisions, it is becoming more important for firms to know when to invest to reduce buyer uncertainty. This article argues that today's firms should view...

Although we have many tools to understand the effect of regulation on competition, we know little about the importance of enforcement in explaining the impact of regulation. For this purpose, this paper uses data from Spanish local television industry in Spain from 1995 through 2001, which...

We examine the effects of mobile termination rate regulation in asymmetric oligopolies. We do this by extending existing models of asymmetric duopoly and symmetric oligopoly where consumer expectations about market shares are passive. We first calibrate product differentiation parameters using...

In Portugal, the telecommunications incumbent o®ers broadband access to the Inter- net, both through digital subscriber line and cable modem. In this article, we estimate the impact on broadband access to the Internet of the structural separation of these two businesses. We use a panel of...

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 oligopolistic firms' incentives to share customer information about past purchase history in a situation where firms are uncertain about whether a particular consumer considers the product offerings complements or substitutes. By addressing this new type of behavior-based price...

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...
