\documentstyle[portada,11pt]{article} This paper shows that the presence of private information in an economy can be a source of market incompleteness even when it is feasible to issue a set of securities that completely eliminates the informational asymmetries in equilibrium. We analyze a...

We use CEX repeated cross-section data on consumption and income, to evaluate the nature of increased income inequality in the 1980s and 90s. We decompose unexpected changes in family income into transitory and permanent, and idiosyncratic and aggregate components, and estimate the contribution...

The paper proposes a numerical solution method for general equilibrium models with a continuum of heterogeneous agents, which combines elements of projection and of perturbation methods. The basic idea is to solve first for the stationary solution of the model, without aggregate shocks but with...

Any electoral system has an electoral formula that converts vote proportions into parliamentary seats. Pre-electoral polls usually focus on estimating vote proportions and then applying the electoral formula to give a forecast of the parliament's composition. We here describe the problems...

In this paper we explore the accumulation of capital in the presence of limited insurance against idiosyncratic shocks, borrowing constraints and endogenous labor supply. As in the exogenous labor supply case (e.g. Aiyagari 1994, Huggett 1997), we find that steady states are characterized with...

Dubey and Geanakoplos [2002] have developed a theory of competitive pooling, which incorporates adverse selection and signaling into general equilibrium. By recasting the Rothschild-Stiglitz model of insurance in this framework, they find that a separating equilibrium always exists and is...

We examine the effects of extracting monetary policy disturbances with semi-structural and structural VARs, using data generated by a limited participation model under partial accommodative and feedback rules. We find that, in general, misspecification is substantial: short run coefficients...

This paper investigates the properties of an international real business cycle model with household production. We show that a model with disturbances to both market and household technologies reproduces the main regularities of the data and improves existing models in matching international...
