This course covers practical numerical techniques to solve single-agent and industry-level quantitative dynamic models. We will cover important topics in both discrete time and continuous time setups. We will touch upon approximate dynamic programming methods in order to overcome the “curse of dimensionality” problems in realistic applications.
The applications of these techniques center around three broad areas: (1) Solving a dynamic discrete choice model: we look at individual learning, firm innovation, and entry/exit. (2) Solving a dynamic continuous choice model: we look at individual consumption/saving and firm investment/borrowing. (3) Solving a basic continuous time dynamic programming problem: consumer search and product innovation. (4) The application to industry evolution bridges models of competitive industry dynamics w/ models where granular firms are important for aggregate outcomes
