We investigate the interactions between optimal regulation and external credit constraints. When part of a regulated firm is owned by foreign investors, a credit-constrained country who wants to send profits abroad has to generate enough surplus in the trade account in order to compensate...

We study optimal linear income taxation in a model with heterogeneous agents where earnings potentials are endogenously determined through human capital accumulation. Agents differ in initial conditions and ability to learn. Capital market imperfections prevent poor agents to invest optimally in...

We study the accumulation of human capital and the behavior of consumption and earnings in a life cycle equilibrium model with endogenous borrowing constraints. Constraints arise endogenously from the inalienability of human capital and the limited punishments that creditors are able to impose...

How do firms' financial constraints, which restrict their borrowing, dynamically impact exports? This paper finds that after controlling for the endogeneity of financial constraints, constrained firms are less likely to export, and relaxing financial constraints leads to an increase in exports....

This paper investigates the determinants of inequality in human capital with an emphasis on the role of the credit constraints. We develop and estimate a model in which individuals face uninsured human capital risks and invest in education, acquire work experience, accumulate assets and smooth...

About 20% of U.S. households are credit constrained. This research analyzes credit constraints among those who have applied for credit and controls for the effects of past credit behavior on being credit constrained. It is the first to identify the impact on being credit constrained of being...

This paper builds a banking DSGE model with endogenous loan-to-value ratios which capture complex relationships between banks and firms. Reflecting the relationship between banks and enterprises, the loan-to-value ratio for state-owned enterprises is endogenously greater than that for private...
