We develop a method that uses second order approximations of the policy functions to the planner's Bellman equation to obtain expressions for the unconditional and conditional moments of debt and taxes in closed form such as the mean and variance of the invariant distribution as well as the speed of mean reversion. Lucas, Robert, and Thomas Sargent. The hypothesis holds that people make unbiased forecasts.
