We develop an endogenous grid method for models with the option to default in which price schedules are endogenously determined in equilibrium and depend on individuals’ states. The algorithm has noticeable computational benefits in efficiency and accuracy. We obtain these computational...

Default risk models have been widely employed to assess the ability of households and sovereigns to insure themselves against shocks. Grid search has often been used to solve these models because the complexity of the problem prevents the use of faster but less general methods. In this paper, we...

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...

Should public policies address inequality due to heterogeneous life expectancy? Intuitively, taking short life as a disadvantage, such policies should favor those with high mortality. Yet, pension systems implicitly redistribute from low-life-expectancy to high-life-expectancy people. Moreover,...

How do differences in the government’s political and commitment structure affect the aggregate economy, inequality, and welfare? I analyze this question, using a calibrated Aiyagari’s (1994) economy with wealth effects of labor supply wherein a flat tax rate and transfers are endogenously...

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