Numerical methods in economics

Prof.ssa Renata Bottazzi

  • Date:

    01 APRIL
    30 APRIL 2023
     from 11:00 to 13:00
  • Event location: Aula IV, Via Belle Arti 41 and STAT PhD Classes Virtual Room - In presence and online event

  • Type: Cycle 38 - Short courses and seminars

Aims: The first part of the course is devoted to introducing the theoretical setup: recursive methods are discussed in relation to standard dynamic models, such as a lifecycle model of consumption and savings; and, the numerical methods that are typically used for the computational solution and simulation of such models are introduced. The second part of the course is devoted to the practical implementation in Matlab of the methods acquired in the first part.

Learning outcomes: After completing the course students should have an understanding of how to numerically solve and simulate dynamic optimisation models in economics.

Final exam: Group presentation.

Course contents
- Theory of Dynamic Programming (DP): Bellman equation and recursive solution.
- Numerical methods for DP problems: value function iteration and policy function iteration. Interpolation methods, numerical integration and simulation of the model.
- Analysis of an economic model in finite horizon: solution and estimation methods for a simple life cycle consumption and savings model. Infinite horizon and solution methods.
- Practical implementation of a simple DP model in Matlab.
