This paper uses new confidential Census data to revisit the relationship between firm size, cyclicality, and financial frictions. First, we find that large firms (the top 1 percent by size) are less cyclically sensitive than the rest. Second, high and rising concentration implies that the higher cyclicality of the bottom 99 percent of firms only has a modest impact on aggregate fluctuations. Third, differences in cyclicality are not simply explained by financing, and in fact appear largely unrelated to proxies for financial strength. We instead provide evidence for an alternative mechanism based on the industry scope of the very largest firms. (JEL D22, E32, G32, L25)

Conditions of secular stagnation--low interest rates, below target inflation, and sluggish output growth--now characterize much of the global economy. We consider a simple two-country textbook model to examine how capital markets transmit secular stagnation and to study policy externalities across countries. We find capital flows transmit recessions in a world with low interest rates and that policies that attempt to boost national saving are beggar-thy-neighbor. Monetary expansion cannot eliminate a secular stagnation and may have beggar-thy-neighbor effects, while sufficiently large fiscal interventions can eliminate a secular stagnation and carry positive externalities.
