This paper proposes a simple method for guiding researchers in developing quantitative models of economic fluctuations. We show that a large class of models, including models with various frictions, are equivalent to a prototype growth model with time varying wedges that, at least on face value, look like time-varying productivity, labor taxes, and capital income taxes. We label the time varying wedges as efficiency wedges, labor wedges, and investment wedges. We use data to measure these wedges and then feed them back into the prototype growth model. We then assess the fraction of fluctuations accounted for by these wedges during the great depressions of the 1930s in the United States, Germany, and Canada. We find that the efficiency and labor wedges in combination account for essentially all of the declines and subsequent recoveries. Investment wedge plays at best a minor role.

The fiscal year and the calendar year coincide for a large fraction of firms traded in the New York and American Stock Exchanges. It is therefore possible that part of the large positive abnormal return earned by stocks as a group during the first week of trading in January may be due to temporal resolution of uncertainty accompanying the end of the fiscal year. We study this hypothesis by examining whether stocks of firms with fiscal years ending in months other than December also realize positive abnormal returns, following the end of their fiscal years. We find that there are no excess returns for such firms in the first five trading days following the end of the fiscal year.
