The paper presents a computationally efficient method to solve overlapping gener- ations models with asset choice. The method is used to study an OLG economy with many cohorts, up to 3 different assets, stochastic volatility, short-sale constraints, and subject to rather large technology shocks....

We propose a new welfare criterion that allows us to rank alternative financial market structures in the presence of belief heterogeneity. We analyze economies with complete and incomplete financial markets and/or restricted trading possibilities in the form of borrowing limits or transaction...

Workers might change jobs for many reasons. They might fall out with the boss and so decide to change employer, or learn that the job is not really for them, or they might accept a poorly paid job as being preferable to being unemployed - say gathering work experience improves one's CV - and...

This paper provides a systematic analysis of identification in linear social interactions models. This is both a theoretical and an econometric exercise as the analysis is linked to a rigorously delineated model of interdependent decisions. We develop an incomplete information game that...

A long tradition suggests a fundamental distinction between situations of risk, where true objective probabilities are known, and unmeasurable uncertainties where no such probabilities are given. This distinction can be captured in a Bayesian model where uncertainty is represented by the agent's...

We study the gains from trade in a model with endogenously variable markups. We show that the pro-competitive gains from trade are large if the economy is characterized by (i) extensive misallocation, i.e., large inefficiencies associated with markups, and (ii) a weak pattern of cross-country...

The implications of status preference in a simple open economy model will be investigated in this paper. The open economy is modeled as a continuum of identical representative agents who have preferences over consumption and status. In the paper status is identified as relative wealth, which...

This paper presents a characterization of a welfare index for the evaluation of primary goods (to be understood as those goods that all agents should enjoy equally). The welfare associated with a given distribution of n primary goods among m agents is measured as the sum of n real-valued...

This paper analyzes the role of nominal assets in ranking intertemporal budget policies in a growing open economy. The budget policies are ranked in terms of the public's intertemporal stock of tax liabilities. Our main result is that, in a small open economy, the valuation of private and public...

In the empirical literature, monetary policy shocks are commonly measured as an innovation to a short-term nominal interest rate. In contrast, the majority of monetary business cycle models treats a broad monetary aggregate as the central bank's policy measure. We try overcome this disparity and...
