Several papers have tested the empirical validity of the migration models proposed by Borjas (1987) and Borjas, Bronars, and Trejo (1992). However, to our knowledge, none has been able to disentangle the separate impact of observable and unobservable individual characteristics, and their...

This paper investigates the long-term implications of climate change on local, interregional, and international migration of workers. For nearly all of the world's countries, our micro-founded model jointly endogenizes the effects of changing temperature and sea level on income distribution and...

This paper studies the link between gender-biased technological change in the agricultural sector and structural transformation in Norway. After WWII, Norwegian farms began widely adopting milking machines to replace the hand milking of cows, a task typically performed by women. Combining...

This paper offers a reappraisal of the impact of migration on economic growth for 22 OECD countries between 1986-2006 and relies on a unique data set we compiled that allows us to distinguish net migration of the native-born and foreign-born by skill level. Specifically, after introducing...

This paper describes the theoretical underpinnings and provides empirical evidence for a model that predicts a positive impact of immigration on entrepreneurial activity. Immigrants, we hypothesize, facilitate innovation and entrepreneurship by being willing and able to invest in new skills. At...

In this paper we investigate the nexus between firm labor diversity and innovation using a linked employer-employee data from Denmark. Specifically, exploiting information retrieved from this comprehensive database and implementing proper instrumental variable strategies, we are able to identify...

This paper examines the effects of foreign- and native-born STEM graduates and non-STEM graduates on patent intensity in U.S. metropolitan areas. I find that both native and foreign-born STEM graduates significantly increase metropolitan area patent intensity, but college graduates in non-STEM...

We develop a theoretical model to investigate whether short-term mobility differentially affects innovation in product or process and carry out an empirical analysis with a focus on Africa using firm-level data from the World Bank Enterprise Survey, as well as complementary country level...

We present a novel theory that immigrants facilitate innovation and entrepreneurship by being willing and able to invest in new skills. Immigrants whose human capital is not immediately transferable to the host country face lower opportunity costs of investing in new skills or methods and will...

Creativity is often highly concentrated in time and space, and across different domains. What explains the formation and decay of clusters of creativity? In this paper we match data on thousands of notable individuals born in Europe between the XIth and the XIXth century with historical data on...
