This paper examines how investments in health, through spending on preventive care, affect subsequent spending on medical care among the retired population.Augmenting a traditional dynamic consumption-savings model with two medical care goods, I estimate a structural life cycle model using data...

The method of endogenous gridpoints (ENDG) significantly speeds up the solution to dynamic stochastic optimization problems with continuous state and control variables by avoiding repeated computations of expected outcomes while searching for optimal policy functions. While the method has been...

In dynamic optimization problems with multiple continuous state variables and multiple continuous controls, the method of endogenous gridpoints (ENDG) generates an irregular collection of gridpoints for which standard interpolation techniques do not apply, while alternative interpolation methods...

We present a macroeconomic model calibrated to match both microeconomic and macroeconomic evidence on household income dynamics. When the model is modified in a way that permits it to match empirical measures of wealth inequality in the U.S., we show that its predictions (unlike those of...
