The grid search method has often been used to solve models with default risk because the complexity of the problem prevents the use of more efficient but less general tools. In this paper, we propose an extension of the endogenous grid method for default risk models in which price schedules are...

How do defaults and bankruptcies affect optimal health insurance policy? I answer this question,using a life-cycle model of health investment with an option to default on emergency room(ER) bills and financial debts. I calibrate the model to the U.S. economy and compare the optimalhealth...

In the United States, the employment rate is nearly flat across wealth quintiles with the exception of the first quintile. Correlations between wealth and employment are close to zero or moderately positive. However, incomplete markets models with a standard utility function counterfactually...

Recent studies highlight the adverse effects of school closures in terms of average lifetime income loss, cross-sectional inequality, and intergenerational mobility. We use a simple model of human capital formation to compare two policy instruments that can address these negative consequences:...
