Course Content
This is a course in quantitative macroeconomics with heterogeneous households. Its main thematical focus is on the interaction between inequality on the micro level and aggregate economic outcomes on the macro level. The course will have five modules. First, it will discuss the empirical motivation and household level data sets with the study of household heterogeneity in macroeconomics, and will review the complete markets-representative agent paradigm. The second module will study single household’s intertemporal consumption and labor supply allocation decisions in partial equilibrium under various assumptions about the life horizon and labor income process of the household as well as the capital market structure. In the third module we will discuss the existence, uniqueness and computation of stationary general equilibria of the models analyzed in the second module, and apply it to evaluate the long-run consequences of fiscal policy reforms. The fourth model will be devoted to the analysis aggregate shocks in the class of models from module 2 and 3, both completely unanticipated (so-called MIT) shocks as well as partially anticipated. Applications to recent crises (the financial crisis of 2007-2009 as well as the COVID-19 health crisis) will be presented. The course will conclude, in a fifth module, with an introduction to dynamic models with enforcement and private information frictions, including the evaluation of the empirical predictions of these class of models for consumption and wealth inequality.
