We develop a fairly general and tractable model of investment when workers can invest in multiple skills and different jobs put different weights on those skills. In addition to expected findings such as that younger workers are more likely than older workers to respond to a demand shock by...

In this paper we develop a model capturing key features of the Roy model, a search model, compensating differentials, and human capital accumulation on-the-job. We establish which features of the model can be non-parametrically identified and which can not. We estimate the model and use it to...

The paper studies human capital accumulation over workers' careers in an on the job search setting with heterogenous firms. In renegotiation proof employment contracts, more productive firms provide more training. Both general and specific training induce higher wages within jobs, and with...

The growing use of on-line educational content and related video services has changed the way people access education, share knowledge, and possibly make life decisions. In this paper, we characterize how video content affects individual decision-making and willingness to share in the context of...

Exploiting variation in welfare reform across states and over time and using relevant comparison groups, this study estimates the effects of welfare reform on an important source of human capital acquisition among women at risk for relying on welfare: vocational education and training. The...

In this paper, we survey non-competitive theories of training. With competitive labor markets, firms never pay for investments in general training, whereas when labor markets are imperfect, firm-sponsored training arises as an equilibrium phenomenon. We discuss a variety of evidence which...

In the standard model of human capital with perfect labor markets general training. When labor market frictions compress the structure of wages in the general skills of their employees. The reason is that the distortion in the wage structure" turn technologically' general skills into specific'...

This paper examines the degree to which the learning by doing externality [LBD] calls for an undervalued exchange rate, a policy suggested by recent empirical studies which concluded that mildly undervalued real exchange rate may enhance growth. We obtain mixed results. For an economy where LBD...

A key tenet of the theory of human capital is that investment in skills results in higher productivity. The previous literature has estimated the degree of investment in human capital for individuals by looking at individual wage growth as a proxy for productivity growth. In this paper, we have...
