The course is devoted to the analysis of business cycle fluctuations. This analysis is based on stochastic dy-namic general equilibrium models. The first objective is a good understanding of firms and households's in-tertemporal behaviors, and of the mechanisms by which economic shocks may generate business cycle fluctuations. The role of nominal and real rigidities should be clearly understood. Students should also learn how to assess the quantitative implications of these models by the means of calibration and simulation tech-niques.
Main themes
More specifically, the main topics should include:
- households and firms's intertemporal behaviors;
- Pareto optimality and first welfare theorem;
- adjustment mechanisms in the open economy;
- real business cycle models;
- nominal rigidities and New Keynesian models;
- effects of monetary and fiscal policies.
