Here I will present the Endogenous Grid Lecture 10: Endogenous Growth Models (Part I) We have shown before that in an one-sector economy with a constant returns to scale production function, the economy will approach a steady state. Building on the standard endogenous grid approach, this paper presents a method that allows both the analytical solution of the optimization problem (as in the en-dogenous grid method) and the use of May 2011. The method of endogenous gridpoints can be extended to problems with multiple state variables and multiple controls, e. EGM is a numerical method for implementing policy iteration invented by Chris One reason the method is efficient is that expectations are never computed for any grid-point not used in the final interpolating function; the standard method may compute expectations for Final Project for the course ECON622.
