Bringing Macroeconomics into the Lab

This paper reviews experiments in macroeconomics, pointing out the theoretical justifications, the strengths and weaknesses of this approach. We identify two broad classes of experiments: general equilibrium and partial equilibrium experiments, and emphasize the idea of theory testing that is behind these. A large number of macroeconomic issues have been analyzed in the laboratory: monetary economics, fiscal policy, international trade and finance, growth, lifecycle consumption, labor markets, search models and macroeconomic imperfections. In a large number of cases results give support to the theories tested. We also highlight that experimental macroeconomics has increased the number of tools available to experimentalists.
