This paper demonstrates that insiders can erect barriers to entry and skim rents by sinking costs in human capital when labour markets are otherwise perfectly contestable. The sunk costs nature of human capital investments may result from the need to satisfy ever increasing specialised skill...

Firms may be reluctant to provide general training if workers can quit and use their gained skills elsewhere. "Training contracts" that impose a penalty for premature quitting can help alleviate this inefficiency. Using plausibly exogenous contractual variation from a leading trucking firm, we...

There is an increasing economic literature considering personality. This paper provides an overview on the role of these skills regarding three main aspects of economic analysis: measurement, theoretical modeling, and empirical estimates. Based on the relevant literature from different...

There is an increasing economic literature considering personality traits as a source of individual differences in labor market productivity and other outcomes. This paper provides an overview on the role of these skills regarding three main aspects: measurement, development over the life...

Policy debates about the balance of vocational and general education programs focus on the school-to-work transition. But with rapid technological change, gains in youth employment from vocational education may be offset by less adaptability and thus diminished employment later in life. To test...

As an alternative to traditional academic schooling, vocational schooling in South Africa may serve as a safety valve for students encountering difficulty in the transition from school to work. Yet if ineffective, vocational schooling could also be a sinkhole, offering little chance for success...

In this paper, human capital investments are evaluated by assuming heterogeneous returns to schooling. We use the potential outcome approach to measure the causal effect of human capital investments on earnings as a continuous treatment effect. Empirical evidence is based on a sample of West...

We propose an original model of human capital investments after leaving school in which individuals differ in their initial human capital obtained at school, their rate of return, their costs of human capital investments and their terminal values of human capital at a fixed date in the future....

We derive a tractable nonlinear earnings function which we estimate separately for each individual in the NLSY79 data. These estimates yield five important parameters for each individual: three ability measures (two representing the ability to learn and one the ability to earn), a rate of skill...

We investigate the role of training in reducing the gender wage gap using the UK-BHPS which contains detailed records of training. Using policy changes over an 18 year period we identify the impact of training and work experience on wages, earnings and employment. Based on a lifecycle model and...
