We study learning in perfect competition. A representative price-taking firm sells a good whose quality is unknown to some buyers. The uninformed buyers use the price to infer information about quality. Even though the firm is a price-taker, information is disseminated though the price. It is...

We study the issue of integrating real and financial decisions in a monopoly firm with risk-averse decision-makers. To that end, we combine the decisions of the firm and of the shareholders in a very simple but robust model, with uncertainty in the real market and CARA preferences. We show the...

We study the influence of the financial market on the decisions of firms in the real market. To that end, we present a model in which the shareholders portfolio selection of assets and the decisions of the publicly-traded firms are integrated through the market process. Financial access alters...

Building on Kihlstrom and Mirman (1974)’s formulation of risk aversion in the case of multidimensional utility functions, we study the effect of risk aversion on optimal behavior in a general consumer’s maximization problem under uncertainty. We completely characterize the relationship...

We consider the original Arrow-Lind framework in which a government undertakes a risky project to be shared among many taxpayers. In our model, the taxpayers decide the level of participation in the risky project. Moreover, the amount of taxes collected by the government fully finances the...

We study the effect of an asymmetric environment on risk sharing. In our model, entrepreneurs consider undertaking risky projects in the real sector as well as selling part of their projects to investors. To capture the idea of an asymmetric environment, the returns on the alternative risk-free...

We study the effect of changing income on optimal decisions in the multidimensional expected utility framework with strongly separable preferences. Using the Kihlstrom and Mirman (1974) (KM) utility representation, we show that the effect of changing income can be decomposed into a modified...

We introduce learning in a Brock-Mirman environment and study the effect of risk generated by the planner's econometric activity on optimal consumption and investment. Here, learning introduces two sources of risk about future payoffs: structural uncertainty and uncertainty from the anticipation...

We study the influence of the financial market on the decisions of firms in the real market. To that end, we present a model in which the shareholders’ portfolio selection of assets and the decisions of the publicly-traded firms are integrated through the market process. Financial access...

We study the informational role of prices. To that end, we consider the framework of a dominant firm with a competitive fringe. When the competitive fringe is large enough, there exists a unique fully revealing equilibrium, in which the price conveys full information about the quality of the...
