We provide evidence that industries' supply curves are convex. To guide our empirical analysis, we develop a model, in which capacity constraints at the plant level generate convex supply curves at the industry level. The industry's capacity utilization rate is a sufficient statistic for the...

We study optimal monetary and fiscal policy in a New Keynesian model where occasional declines in agents' confidence can give rise to persistent liquidity trap episodes. Unlike in the case of fundamental-driven liquidity traps, there is no straightforward recipe for mitigating the welfare costs...

Quantifying the effects of trade policy in the age of "global value chains" (GVCs) requires an enhanced analytical framework that takes the observed international input-output relations in due account. However, existing quantitative general equilibrium models generally assume that industry-level...
