Product development within and across community-based and geographically dispersed virtual organizations is becoming an increasingly important mechanism through which individual knowledge holders create and disseminate knowledge in joint efforts to generate products. Without the benefits of...

This paper studies the role of internal migration in income convergence across regions in Japan. Neoclassical theory predicts that migration should have been an important source of convergence, but regression results suggest otherwise. The paper investigates the possibility that this discrepancy...

The Paper studies determinants of internal migration in Russia. Using panel data on gross region-to-region migration flows in 1992-99, we estimate the effect of economic, political and social factors. Although overall migration is rather low, it turns out that its intensity does depend on...

We study barriers to labor mobility using panel data on gross region-to-region migration flows in Russia for 1995-2010. We find that barriers that hindered internal migration in 1990s have been generally eliminated by the end of 2000s. In 1990s many poor Russian regions were in poverty traps:...

This paper studies the role of strong versus weak ties in the rural-to-urban migration decision in China. We first develop a network model that puts forward the different roles of weak and strong ties in helping workers to migrate to the city. We then use a unique longitudinal data that allows...

This Paper examines city formation in a country whose urban population is growing steadily over time, with new cities required to accommodate this growth. In contrast to most of the literature there is immobility of housing and urban infrastructure, and investment in these assets is taken on the...

Empirical studies consistently report that labour productivity and TFP rise with city size. The reason is that cities attract the most productive agents, select the best of them, and make the selected ones even more productive via various agglomeration economies. This paper provides a...

We develop a new methodology for quantifying the tasks undertaken within occupations using 3,000 verbs from around 12,000 occupational descriptions in the Dictionary of Occupational Titles (DOTs). Using micro-data from the United States from 1880-2000, we find an increase in the employment share...
