Perturbation Methods for Heterogeneous Agent Models

The following lecture is a short-course on how to use perturbation methods to solve heterogeneous agent models. https://github.com/ralphluet/KS_Perturbation_vs_MIT/blob/master/Slides_BayerLuetticke.pdf

You can find the codes to implement this on GitHub as well:
