We document a novel role of heterogeneity in price rigidity: It strongly amplifies the capacity of idiosyncratic shocks to drive aggregate fluctuations. Heterogeneity in price rigidity also completely changes the identity of sectors from which fluctuations originate. We show these results both...

This paper investigates the implications for the nominal exchange rate of a Border Tax Adjustment (BTA) when there is BTA neutrality. A border tax adjustment is a change from an origin-based system of taxation, that taxes exports but exempts imports to a destination-based system that taxes...

The paper analyzes the effects of disembodied technological progress on steady state hours worked in the workhorse New-Keynesian model, which features a neoclassical labor market, and its extension that allows for equilibrium unemployment. Both versions of the model are shown to imply a positive...
