摘要：When do dynamic nonconvexities at the disaggregate level translate into dynamic nonconvexities at the aggregate level? We address this question in a framework where the production of differentiated intermediate inputs is subject to dynamic nonconvexities, and we show that the answer depends on the degree of Hicks-Alien complementarity (substitutability) between differentiated inputs. In our simplest model, a generalization of judd (1985) and Grossman and Helpman (1991) among many others, there...
