We juxtapose the effects of trade and technology on employment in U.S. local labor markets between 1990 and 2007. Labor markets whose initial industry composition exposes them to rising Chinese import competition experience significant falls in employment, particularly in manufacturing and among...

We distinguish the impact of information technology adoption on information processing costs and agency costs by conducting a randomized control trial with a bank that adopts a new credit-scoring tool. The availability of scores significantly increases credit committees' effort and output on...

This paper presents empirical evidence that the growth of export manufacturing in Mexico during a period of major trade reforms, the years 1986-2000, altered the distribution of education. I use variation in the timing of factory openings across municipalities to show that school dropout...

This paper directs attention at the globalization of knowledge and knowledge creation as the fundamental global driver of economic outcomes in today's information economy. It documents the globalization of knowledge and spread of scientific research from advanced to developing countries and...

We use a comprehensive dataset of French manufacturing firms to study their internal organization. We first divide the employees of each firm into `layers' using occupational categories. Layers are hierarchical in that the typical worker in a higher layer earns more, and the typical firm...

This paper studies the relation between human capital of suicide bombers and outcomes of their suicide attacks. We argue that human capital is an important factor in the production of terrorism, and that if terrorists behave rationally we should observe that more able suicide bombers are...

Existing learning models attribute failures to learn to a lack of data. We model a different barrier. Given the large number of dimensions one could focus on when using a technology, people may fail to learn because they failed to notice important features of the data they possess. We conduct a...

We report a puzzling pair of facts concerning the organization of science. The concentration of research output is declining at the department level but increasing at the individual level. For example, in evolutionary biology, over the period 1980 to 2000, the fraction of citation-weighted...

Union membership displayed a ∩-shaped pattern over the 20th century, while the distribution of income sketched a ∪. A model of unions is developed to analyze these phenomena. There is a distribution of firms in the economy. Firms hire capital, plus skilled and unskilled labor. Unionization...
