We investigate the speed at which clusters of invention for a technology migrate spatially following breakthrough inventions. We identify breakthrough inventions as the top one percent of US inventions for a technology during 1975-1984 in terms of subsequent citations. Patenting growth is signi…cantly higher in cities and technologies where breakthrough inventions occur after 1984 relative to p...

Individuals with disabilities face greater challenges in the labor market than able-bodied individuals and a growing body of research is finding that their children also tend to have more developmental problems than the children of able-bodied parents. Can transfer payments help reduce this gap? In this paper, we present the first evidence on how parental disability benefits affect the well-bei...

Grime and Punishment: Job Insecurity and Wage Arrears in the Russian Federation Using information from two complementary household survey data sets, we show that the dominant form of labor market adjustment in the Russian transition process has been the delayed receipt of wages. More than half the workforce is experiencing some form of disruption to their pay. Wage arrears are found across the ...

Estimates of the natural rate of unemployment are important in many macroeconomic models used by economists and policy advisors. This paper shows how such estimates might benefit from closer attention to regional developments. Regional business cycles do not move in lockstep and greater dispersion among regions can affect estimates of the natural rate of unemployment. There is microeconomic evi...

Does Employment Protection Help Immigrants? Evidence from European Labor Markets High levels of employment protection reduce hiring and firing and have a theoretically ambiguous effect on the employment level. Immigrants, being new to the labor market, may be less aware of employment protection regulations and less likely to claim their rights, which may create a gap between the costs for emplo...

Numerous studies document, on the one hand, a positive correlation between crime and unemployment and, on the other hand, a negative correlation between the crime rate and educational attainment levels within given communities. We study this phenomenon in the context of a search-equilibrium model, in which agents choose between formal employment and pursuing crime related activities (theft). Pr...

Head-content or Headcount? Short-term Skilled Labour Movements as a Source of Growth This paper contributes a theoretical model to study the effects of short-term movements of skilled labour on a country’s economic growth.
