The empirical analysis in "International R&D Spillovers" (Coe and Helpman, 1995) is first revisited by applying modern panel cointegration estimation techniques to an expanded data set that we have constructed for the purpose of this study. The new estimates confirm the key results reported in...

The Helpman-Razin model of international trade under uncertainty is extended to allow for country-specific productivi ty shocks. It is shown that, for the multiple-sector multiple-factor case, there exists a set of interesting sufficient conditions under w hich it is possible to predict the...

We develop a model of common agency with complete information and general preferences with non-transferable utility, and prove that the principals’ Nash equilibrium in truthful strategies implements an efficient action. We apply this theory to construct a positive model of public finance,...

Polities differ in the extent to which political parties can pre-commit to carry out promised policy actions if they take power. Commitment problems may arise due to a divergence between the ex ante incentives facing national parties that seek to capture control of the legislature and the ex...

The paper first describes a number of political economy approaches that have been developed to explain trade policies. All approaches are presented in a unified framework that helps to identify the key differences between them. These comparisons revolve around tariff formulas that are predicted...

We review the literature on the links between technology and international trade. The older literature assumed exogenous technologies and focused on their effects on the structure of foreign trade and on welfare. Recently much of the effort has been on explaining technological change. As a...

We study the determinants of the extent of outsourcing and of direct foreign investment in an industry in which producers need specialized components. Potential suppliers must make a relationship-specific investment in order to serve each prospective customer. Such investments are governed by...

The authors construct a model of the product cycle featuring endogenous innovation and technology transfer. Competitive entrepreneurs in the industrialized North introduce new products whenever the expected present value of oligopoly profits exceeds the cost of product development. In the...
