In this paper we study how aggregate output responds to the arrival of a new General Purpose Technology (GPT) by looking at adjustment mechanisms that operate through labour markets. We show that under a wide set of circumstances the arrival of a new GPT that raises long-run output can trigger a...

We study budget formation in a model featuring separation of powers. In our model, the legislature designs a budget bill that can include a cap on total spending and earmarked allocations to designated public projects. Each project provides random benefits to one of many interest groups. The...

This Paper builds a multi-country, multi-sector general equilibrium model that explains the decision of heterogeneous firms to serve foreign markets either through exports or local subsidiary sales (FDI). These modes of market access involve different relative costs, some of which are sunk while...

New developments in the world economy have triggered research designed to better understand the changes in trade and investment patterns, and the reorganization of production across national borders. Although traditional trade theory has much to offer in explaining parts of this puzzle, other...

We study the politics of intergenerational redistribution in an overlapping-generations model with short-lived governments. The successive governments – who care about the welfare of the currently-living generations and possibly about campaign contributions – are unable to pre-commit the...

We generalize the Antràs and Helpman (2004) model of the international organization of production in order to accommodate varying degrees of contractual frictions. In particular, we allow the degree of contractibility to vary across inputs and countries. A continuum of firms with heterogeneous...

We develop an equilibrium model of industrial structure in which the organization of firms is endogenous. Differentiated consumer products can be produced either by vertically integrated firms or by pairs of specialized companies. Production of each variety of consumer good requires a unique,...

During the last two decades new research has greatly advanced our understanding of the structure of world trade. This article reviews the empirical literature that grew out of this effort. I emphasize the interplay between theory and empirical research that was an important driving force behind...

The empirical analysis in "International R&D Spillovers" [Coe, D., Helpman, E., 1995. International R&D Spillovers. European Economic Review, 39, 859-887] is first revisited on an expanded data set that we have constructed for the purpose of this study. The new estimates confirm the key results...
