This paper deals with credit market imperfections and idiosyncratic risks in a two-sector heterogeneous agent dynamic general equilibrium model of occupational choice. We focus especially on the effects of tightening financial constraints on macroeconomic performance, entrepreneurial...

This paper examines the consequences of international financial integration in a two-sector heterogeneous-agent dynamic general equilibrium model of occupational choice with financial constraints and idiosyncratic risks. We discuss the macroeconomic and distributional effects of financial market...

This paper considers the macroeconomic implications of a set of empirical studies finding a high degree of dispersion in preference heterogeneity. It develops a model with both uninsurable idiosyncratic income risk and risk aversion heterogeneity to quantify their effects on wealth inequality....

Is the Spanish economy positioned at its optimal progressivity level in personal income tax? This article quantifies the aggregate, distributional, and welfare consequences of moving toward such an optimal level. A heterogeneous households general equilibrium model featuring both life cycle and...

We develop a general equilibrium model of earnings, income and wealth heterogeneity in continuous time. We extend existing analytical and numerical methods to solve the model. We calibrate the model to U.S. data and find that stochastic interest rates provide a mechanism to link earnings, income...

What determines wealth inequality and mobility and how can the policy maker influence it? This paper quantifies in closed form the bottom and the top (Pareto) tail of the distribution in a continuous-time heterogeneous agent model. Financial market imperfections play a key role, for which...
