I construct and analyze an example of an economy with production and money under conditions of uncertainty, asymmetric information, and an incomplete asset market. For alternative scenarios, which differ in the information available to consumers and firms, I compute the equilibrium prices and...

Markets are incomplete when the assets available to the agents do not span the space of future contingencies. Efficiency is then assessed by the weak criterion of "constrained efficiency" (efficiency relative to the set of allocations compatible with the asset structure). That criterion requires...

The present note highlights the seminal contributions of Diamond, Drèze and Radner towards the integration of financial markets into general equilibrium modeling.

In this paper we illustrate the possible normative relevance of the links between human capital and financial assets via an example related to growth. When the financial structure is complete, growth is indeterminate because individual allocations between human capital and a tradable asset are...

Profit maximization is not a well defined objective when markets are incomplete. Several criteria of investment choice have therefore been put forward in the literature, some of which crucially hinge upon aggregation of shareholders' preferences, as is the case with the criteria proposed by...

We propose an objective for the firm in a model of production economies extending over time under uncertainty and with incomplete markets. We derive the objective of the firm from the assumption of initial-shareholders efficiency. Each shareholder is assumed to communicate to the firm her...

In an open economy, outside money in positive supply does not eliminate the real indeterminacy which arises under uncertainty and incomplete asset markets. If money supply is subject to shocks or is not perfectly credible in all countries, the level of a fixed exchange rate matters. Analogous...

We consider a general equilibrium model with incomplete financial markets and nominal assets. Asset prices are given. Let D be the number of "missing" assets. If the number of agents is greater than 2(D+ 1) and the number of period zero commodities greater than (2D + 1), there is a dense,...

The paper analyzes the process of market selection of investment strategies in an incomplete market of short-lived assets. In the model under study, asset payoffs depend on exogenous random factors. Market participants use dynamic investment strategies taking account of the available information...

In this paper, we provide a characterization of interim inefficiency in stochastic economies ofoverlapping generations under possibly sequentially incomplete markets. With respect to the established body of results in the literature, we remove the hypothesis of two-period horizons,by considering...
