We study how the output gap affects potential output over time-i.e., the dynamic hysteresis effect. To do so, we introduce novel unobserved components (UC) models that consider hysteresis as a sequence of lagged effects, thus separating the long-run recession-induced adverse effects from other...

We study the aggregate implications of (S,s) inventory policies in a dynamic general equilibrium model with aggregate uncertainty. Firms in the model's retail sector face idiosyncratic demand risk, and (S,s) inventory policies are optimal because of fixed order costs. The distribution of...

In a 1957 paper, Robert Solow exploited the mathematical properties of the aggregate production function to isolate the role of disembodied “technical change” in economic growth. Solow's method allowed to disentangle the role of technical change from that of production factors, with the...
