One country that tries to reduce greenhouse gas emissions may fear that other countries get a competitive advantage and increase emissions ("leakage"). Estimates from computable general equilibrium (CGE) models such as Elliott et al (2010a,b) indicate that 15% to 25% of abatement might be offset...

We examine entry across 113 national markets in 16 different industries using a comprehensive data set of French manufacturing firms. The data are unique in indicating how much each firm exports to each destination. Looking across all manufacturers: (1) Firms differ substantially in export...

We use a forty-two country model of production and trade to assess the implications of eliminating current account imbalances for relative wages, relative GDP's, real wages, and real absorption. How much relative GDP's need to change depends on flexibility of two forms: factor mobility and the...

A recent literature has introduced heterogeneous firms into models of international trade. This literature has adopted the convention of treating individual firms as points on a continuum. While the continuum offers many advantages this convenience comes at some cost: (1) Shocks to individual...

We examine productivity growth since World War II in the five leading research economies: West Germany, France, the United Kingdom, Japan, and the United States. Available data on the capital-output ratio suggest that these countries grew as they did because of their ability to adopt more...

We explore the determinants of research specialization across countries and its consequences for relative wages. Using a dynamic Ricardian model we examine the effects of faster international technology diffusion and lower trade barriers on the incentive to innovate. In the absence of any...

While policymakers often assume venture capital has a profound impact on innovation, that premise has not been evaluated systematically. We address this omission by examining the influence of venture capital on patented inventions in the United States across twenty industries over three decades....

European countries do less research than Japan and the United States. We use a quantitative multi-country growth model to ask: (i) Why is this so? (ii) Would there be any benefit to expanding research in Europe? (iii) What would various European research promotion policies do? We find that (i)...

Innovative activity is highly concentrated in a handful of advanced countries. These same countries are also the major exporters of capital goods to the rest of the world. We develop a model of trade in capital goods to assess its role spreading the benefits of technological advances. Applying...

We investigate the cause of an unprecedented surge of U.S. patenting over the past" decade. Conventional wisdom points to the establishment of the Court of Appeals of the" Federal Circuit by Congress in 1982. We examine whether this institutional change benefitted patent holders, explains the...
