We study the effects of a voluntary skill certification scheme in an online freelancing labour market. We show that obtaining skill certificates increases freelancers' earnings. This effect is not driven by increased freelancer productivity but by decreased employer uncertainty. The increase in...

In the Netherlands auditors can be trained in a part-time educational track in which students combine working and studying or in a full-time educational track. The former training is relatively firm-specific whereas the latter training is relatively general. Applying human capital theory, we...

The long-term earnings losses of displaced workers are substantial. We investigate the role of post-displacement occupational matching in explaining the cost of job displacement. We combine German administrative data on the work history of displaced workers with information on the task content...

We estimate the labor market consequences of corporate diversification using worker-firm matched data from the U.S. Census Bureau. We find evidence that workers in diversified firms have greater cross-industry mobility. Displaced workers experience significantly smaller losses when they move to...

We document differences in human capital deployment between diversified and focused firms. We find that diversified firms have higher labor productivity and that they redeploy labor to industries with better prospects in response to changing opportunities. The opportunities and incentives...

While there is a wealth of literature dealing with the spatial nature of knowledge and its transferral, I argue that the underlying mechanisms have not been sufficiently understood. Existing research relating the geography of inflows to firm productivity does not adequately address firm and...

We use a unique data set on employee turnover by industry in Arizona to test competing theories of turnover. We find that industries with lower establishment survival rates have more employee turnover, even after controlling for differences in the distribution of employee tenure. This result is...

We argue that productive firms share rents with workers only in occupations where workers have individual hold-up power. We present a model of wage determination where firms produce using a novel generalization of Kremer (1993)'s O-ring production function. Workers have individual hold-up power...
