multiplier) at equilibrium of a class of static economies (complete and incomplete information and with different social structures, eg. overlapping groups, simple networks) of social interactions, derive comparative statics analysis of such properties and study identification with respect to...

We study the wealth distribution in Bewley economies with idiosyncratic capital income risk (entrepreneurial risk). We find, under rather general conditions, a unique ergodic distribution of wealth which displays fat tails (a Pareto distribution in the right tail).

This paper analyzes a class of competitive economies with production, incomplete financial markets, and agency frictions. Firms take their production, financing, and contractual decisions so as to maximize their value under rational conjectures. We show that competitive equilibria exist and that...

We study the wealth distribution in Bewley economies with idiosyncratic capital income risk. We show analytically that under rather general conditions on the stochastic structure of the economy, a unique ergodic distribution of wealth displays a fat tail; more precisely, a Pareto distribution in...

We study procrastination in the context of a field experiment involving students who must exert costly effort to complete certain tasks by a fixed deadline. Students display a strong demand for commitment in the form of self-imposed deadlines. However, deadlines appear not to increase task...

This paper analyzes a class of competitive economies with production, incomplete financial markets, and agency frictions. Firms take their production, financing, and contractual decisions so as to maximize their value under rational conjectures. We show that competitive equilibria exist and that...

We develop a dynamic model of identity formation that explains why ethnic minorities may choose to adopt oppositional identities (i.e. some individuals may reject or not the dominant culture) and why this behavior may persist over time. We first show that the prevalence of an oppositional...

Social interactions arguably provide a rationale for several important phenomena, from smoking and other risky behavior in teens to e.g., peer effects in school performance. We study social interactions in dynamic economies. For these economies, we provide existence (Markov Perfect Equilibrium...

We study financial markets where agents share risks, but have incentives to default and their financial positions might not be transparent, that is, might not be mutually observable. We show that a lack of position transparency results in a counterparty risk externality, that manifests itself in...
