The diversity of social interaction within economic communities affects productivity and growth, and is itself shaped by economic conditions. These reciprocal effects raise the possibility of multiple equilibria, of setting a socially polarized economy stagnating in poverty on a new path of...

We study the importance of linguistic diversity in the workplace for workplace productivity. While cultural diversity might improve productivity through new ideas and innovation, linguistic diversity might increase communication costs and thereby reduce productivity. We apply a new measure of...

We empirically investigate the relationship between a country's economic complexity and the diversity in the birthplaces of its immigrants. Our cross-country analysis suggests that countries with higher birthplace diversity by one standard deviation are more economically complex by 0.1 to 0.18...

We use recent immigration data from 195 countries and propose an index of population diversity based on people's birthplaces. This new index is then decomposed into a size (share of foreign born) and a variety (diversity of immigrants) component and is available for 1990 and 2000 disaggregated...

What is the role of international migrants and, specifically, migrant networks in shaping political attitudes and behavior in migrant sending countries? Our theoretical framework proposes that migration might change individual social identities and thus stimulate intrinsic motivation for...

Institutions are now widely believed to be important in explaining performance. In this paper, we analyze whether commonly used measures of institutions have any significant, measurable impact on performance, whether of countries or firms. We look at three 'levels' of institutions and associated...

We construct an endogenous growth model that includes a cultural variable along the dimension of individualism-collectivism. The model predicts that more individualism leads to more innovation because of the social rewards associated with innovation in an individualist culture. This cultural...

An emerging economic literature over the past decade has made use of international tests of educational achievement to analyze the determinants and impacts of cognitive skills. The cross-country comparative approach provides a number of unique advantages over national studies: It can exploit...

We conceptualise social entrepreneurship as a source of social capital which, when present in the environment, enhances commercial entrepreneurship. We also argue that social entrepreneurship should be recognised as a second form of Baumol's (1990) productive entrepreneurship and that it will...

This paper investigates the determinants of economic growth emphasizing the role of institutional quality, social fragmentation, and increasing global integration on recent growth experience. Our longitudinal data consists of 103 countries covering the period 1992-2005. We find that democracies...
