Solving the Stochastic Growth Model by Using a Recursive Mapping Based on Least Squares Projection.
A method to solve a standard version of a stochastic growth model is decribed. The method uses the equilibrium first-order condition (a Euler equation) and the linear least squares projection operator to construct a recursive mapping to compute the solution. At the solution, the marginal valuation of the end-of-period state (a dual price) satisfies certain orthogonality conditions.
