We describe a sparse-grid collocation method to compute recursive solutions of dynamic economies with a sizable number of state variables. We show how powerful this method can be in applications by computing the non-linear recursive solution of an international real business cycle model with a...

We compare the performance of perturbation, projection, and stochastic simulation algorithms for solving the multi-country RBC model described in Den Haan et al. (this issue). The main challenge of solving this model comes from its large number of continuous-valued state variables, ranging...

Previous research suggests that, in partial equilibrium, individuals whose decision-making exhibits a present-bias--such as hyperbolic discounters who tend to over-consume--will be in favor of having a floor imposed on their savings. In this paper, I show it is quite difficult for the...
