Extending Milgrom and Roberts (1982) we present an infinite horizon entry model, where the incumbent(s) may use the current price to signal its strength to deter entry. We show that, due to the importance of entrants' types on the post-entry duopoly/oligopoly profits, the incumbent(s) may want...

This paper considers a vertically separated industry with an upstream monopolist who supplies an essential input to two downstream Cournot firms. This situation is relevant to a number of sectors, including the telecommunications industry where trunk operators must have access to the local...

The problem of a monopolist firm that supplies an essential input to other firms that compete in the final downstream market is crucial in many utility industries that use a network. When downstream firms have different degrees of efficiency, then it could be feasible to charge them different...

Generalizing the idea that price momentum can be explained by different levels of uncertainty inherent in the information structure, we implement signal-specific differences in uncertainty in a Kyle type model of strategic trading. We derive the equilibrium in a single-auction setting as well as...

The digital revolution of pricing enables retailers to change their prices more frequently than ever before. While the industry endorses this development, critics fear it could foster excessive price fluctuations. This paper studies price fluctuations in the context of brick-and-mortar retailing...

Emerging tracking data allow precise predictions of individuals' reservation values. However, firms are reluctant to conspicuously implement personalized pricing because of concerns about consumer and regulatory reprisals. This paper proposes and applies a method which disguises personalized...

In this paper, we develop a model in which overconfident market participants and rational speculators trade against trend-chasers. We show that the growth and the burst of a financial bubble stem from positive feedback trading. However, the presence of overconfident traders and the risk aversion...

We analyse a Kyle-type continuous-time market model in which liquidity trading is correlated with a noisy public signal that is released continuously. We show that, in contrast to the previous literature, Kyle's lambda, the price sensitivity to the order flow, can even be nonmonotonic, depending...

We study a duopoly where the two price setting firms have symmetric information. The firms produce substitute goods with a state dependent common value. The information that is available to both firms about the unknown state of nature is also available to the consumers, who also have access to...
