We study the effects of varying the confidence level of speculators and the confidence level attributed to them by their competitors, about the precision of their private information in the framework of the model of financial markets with imperfect competition a la Kyle (1989).

We analyze the effects of uncertainty and private information on horizontal mergers. Firms face uncertain demands or costs and receive private signals. They may decide to merge sharing their private information. If the uncertainty parameters are independent and the signals are perfect,...

This paper examines competition in a spatial model of two-candidate elections, where one candidate enjoys a quality advantage over the other candidate. The candidates care about winning and also have policy preferences. There is two-dimensional private information. Candidate ideal points as well...

We show that incentive efficient allocations in economies with adverse selection and moral hazard can be determined as optimal solutions to a linear programming problem and we use duality theory to obtain a complete characterization of the optima. Our dual analysis identifies welfare effects...

We develop a model of insider trading where agents have private information either about liquidation value or about supply and behave strategically to maximize their profits. The supply informed trader plays a dual role in market making and in information revelation. This trader not only reveals...

We propose a model based on competitive markets in order to analyze an economy with several principals and agents. We model the principal-agent economy as a two-sided matching game and characterize the set of stable outcomes of this principal-agent matching market. A simple mechanism to...

A signalling model is developed to investigate the consequences of corporate income taxation in the presence of adverse selection in the equity market. The model obtains a unique, informationally-constrained efficient equilibrium in which a better quality firm retains more inside-equity, and, as...

This paper develops a signaling model to investigate a firm's optimal financial response to corporate income taxation under informational asymmetries. The model obtains informationally constrained efficient equilibria in which a firm's debt level and inside equity position jointly serve as a...

I analyze a market in which a price-taking buyer buys a variable-quality good from a population of sellers, contrasting the case where quality is a seller's private information to that where it is public information. Average quality traded under private information can be either higher (quality...
