This paper provides a systematic analysis of the welfare effects of vertical integration by a monopolistic input supplier into a monopolistically competitive downstream industry. We give sufficient conditions on consumer preferences that lead to Pareto improving vertical integration. We...

This paper studies the price dynamics induced by strategic firm behaviour in the presence of consumer learning about the uncertain quality differential of the products offered by a duopoly. It is found that consumers learn slowly and also that prices converge slowly to full-information levels. A...

We compare steady states of open loop and locally stable Markov perfect equilibria (MPE) in a general symmetric differential game duopoly model with costs of adjustment. Strategic incentives depend on whether an increase in the state variable of a firm hurts or helps the rival and on whether...

For Bayesian games of strategic complementarities, we provide a constructive proof of the existence of a greatest and a least Bayes-Nash equilibrium - each one in strategies monotone in type - if the payoff to a player displays increasing differences in own action and the profile of types, and...

A version of the herding prediction model with a rational expectations flavor is reexamined in the light of incentive theory. The welfare loss at the market solution with respect to the incentive efficient solution can be decomposed into an information externality term minus an incentive cost...

When is the modeller introducing more error when analysing a Cournot market with private cost information - when ignoring market power or when ignoring the impact of incomplete information? Is the welfare loss at the market outcome driven by private information or by market power? The answer,...

We assess how banking competition will be affected by the process of deregulation and integration in European financial markets, drawing on the lessons of recent research in finance, banking and industrial organization. Our central thesis contends that the main effect of integration will be to...

We provide sufficient conditions in finite-horizon multi-stage games for the value function of each player, associated to extremal Markov perfect equilibria, to display strategic complementarities and for the contemporaneous equilibrium to be increasing in the state variables.

Central bank policy suffers from time-inconsistency when facing a banking crisis: A bailout is optimal ex post but ex ante it should be limited to control moral hazard. Dollarization provides a credible commitment not to help at the cost of not helping even when it would be ex ante optimal to do...

A finite number of sellers (n) compete in schedules to supply an elastic demand. The costs of the sellers have uncertain common and private value components and there is no exogenous noise in the system. A Bayesian supply function equilibrium is characterized; the equilibrium is privately...
