Empirical evidence indicates a close association between multinational firms and knowledge capital, a public good within the firm. We model a firm which wishes to exploit its knowledge capital abroad, but whose workers learn all the knowledge necessary for production and can defect and produce...

We develop a two-country model of endogenous innovation and imitation in order to study the interactions between these two processes. Firms in the North race to bring out the next generation of a set of technology-intensive products. Each product potentially can be improved a countably infinite...

In this survey, I discuss four sources of growth of knowledge: research, schooling, learning by doing, and training. In trying to disentangle what is important, I emphasize the following facts: (1) even the most advanced countries spend far more on adoption of existing technologies than on...

The Clean Development Mechanism (CDM) is a project-based carbon trade mechanism that subsidizes the users of climate-friendly technologies and encourages technology transfer. The CDM has provided financial support for a large share of Chinese wind projects since 2002. Using pooled...

This paper examines the importance of learning-by-doing that is specific not just to individual firms, but to pairs of firms working together in a contracting relationship. Using new, detailed data from the oil and gas industry, I find that the joint productivity of an oil production company and...

This paper summarizes the main findings of the recent studies that have constructed top incomeand wealth shares series over the century for a number of countries using tax statistics. Most countries experience a dramatic drop in top income shares in the first part of the century due to a...

This paper provides the first systematic analysis of the link between economic, political, and social conditions and the global phenomenon of ISIS foreign fighters. We find that poor economic conditions do not drive participation in ISIS. In contrast, the number of ISIS foreign fighters is...

In 1953 the Western Allied powers implemented a radical debt-relief plan that would, in due course, eliminate half of West Germany's external debt and create a series of favourable debt repayment conditions. The London Debt Agreement (LDA) correlated with West Germany experiencing the highest...

We study how international trade affects manufacturing employment and the relative wage of unskilled workers when goods and services are traded with different intensities. Manufacturing trade reduces manufacturing prices worldwide, which reduces manufacturing employment if manufactures and...

Using data over more than a century, we show that shifts in the location of manufacturing industries are a domestic reflection of what the international trade literature refers to as the product cycle in a cross-country context, with industries spawning in high-wage areas with larger pools of...
