This course is devoted to the analysis of economic fluctuations and macroeconomic policies. We present the stylized facts of business cycles and present methods to estimate the sources of fluctuations. We start by the traditional aggregate-supply aggregate demand model to account for the fluctuations. We then lay down the basic real-business cycle models with intertemporal choices of saving, consumption and labor supply under uncertainty and shocks. We present methods to solve these stochastic models and estimate their empirical relevance. We then analyze the role of money, nominal rigidities and real rigidities in new Keynesian models to explain the effect of demand shocks and supply shocks on output and unemployment. This framework will be used to explain the effect of monetary and fiscal policies and discuss the credibility of public policy.
