Workshop: Advances in Numerical Methods for Economics
June 28, 2013
In the aftermath of the crisis, DSGE modeling using perturbation-based methods has been challenged, as the objective of fine-tuning business cycle fluctuations has been (temporarily) postponed. In addition, models with non-linear constraints have attracted considerable interest as the zero-lower bound on interest or downward nominal rigidities became prominent features of the macroeconomic environment in advanced countries. This has renewed interest from academia and institutional partners toward global, nonlinear, solution methods as a powerful tool to investigate the theory of nonlinear models and to draw quantitative conclusions.
Global methods are also used for a wide range of models where decision rules need to be solved for a large state space, for instance models in which policymakers cannot commit to future policies, dynamic games, etc.
For this reason, the IMF and the Chaire Banque de France at Paris School of Economics are organizing a specialized workshop about recent advances in computational economics. The workshop will focus on the following topics:
- (i) Advances in global methods;
- (ii) Dealing with nonlinearities, and occasionally binding constraints;
- (iii) Delaying the curse of dimensionality (sparse grids, heterogeneous agents);
- (iv) Advanced computational techniques (algorithmic improvements, parallel computing, gpu programming);
- (v) Alternatives to classic rational expectation models (learning, heterogeneous beliefs, agent-based models); and
- (vi) Relations with other computational fields (physics, biology, applied mathematics).
