Invariably across a cross-section of countries and time periods, wealth distributions are skewed to the right displaying thick upper tails, that is, large and slowly declining top wealth shares. In this survey we categorize the theoretical studies on the distribution of wealth in terms of the...

This paper attempts to quantitatively identify the factors that drive wealth dynamics in the U.S. and are consistent with its observed skewed cross-sectional distribution and social mobility. We concentrate on three critical factors: a skewed and persistent distribution of earnings, differential...

Furthermore, equilibria may display specialization on the part of identical firms and, when equilibria are constrained inefficient, may exhibit excessive aggregate risk. Financial decisions of the corporate sector are determined at equilibrium and depend not only on the nature of financial...

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 a general class of models with social interactions that might display multiple equilibria. We propose an estimation procedure for these models and evaluate its efficiency and computational feasibility relative to different approaches taken to the curse of dimensionality implied by the...

We model the opacity of over-the-counter (OTC) markets in a setup where agents share risks, but have incentives to default and their financial positions are not mutually observable. We show that this setup results in excess "leverage" in that parties take on short OTC positions that lead to...

Cultural transmission arguably plays an important role in the determination of many fundamental preference traits (e.g., discounting, risk aversion and altruism) and most cultural traits, social norms, and ideological tenets ( e.g., attitudes towards family and fertility practices, and attitudes...

We propose a theoretical framework to study the determinants of ethnic and religious identity along two distinct motivational processes which have been proposed in the social sciences: cultural conformity and cultural distinction. Under cultural conformity, ethnic identity is reduced by...

We study the dynamics of the distribution of overlapping generation economy with finitely lived agents and inter-generational transmission of wealth. Financial markets are incomplete, exposing agents to both labor income and capital income risk. We show that the stationary wealth distribution is...

We study risky behavior of adolescents. Concentrating on smoking and alcohol use, we structurally estimate a dynamic social interaction model in the context of students' school networks included in the National Longitudinal Study of Adolescent Health (Add Health). The model allows for...
