This paper develops a simple framework for examining human capital accumulation, unemployment, and relative wages in a global economy. It builds on the models of Davis (1998a, b) of trade between a flexible-wage America and a rigid-wage Europe. To this it adds a model of human capital...

We show how the ability to accumulate human capital through formal education and through a learning-by-doing process that occurs on the job affects the dynamic behavior of the human capital stock under a liquidity-constrained and a non-constrained case. When there are alternatives to formal...

This paper demonstrates that considering alternative means of human capital accumulation, such as learning-by-doing, overturns the presumption that formal education is unconditionally beneficial for economic growth. It analyzes a model in which the average level of human capital creates...

This paper considers the impact of endogenous human capital accumulation on optimal tax policy in a life cycle model. Including endogenous human capital accumulation, either through learning-by-doing or learning-or-doing, is analytically shown to create a motive for the government to use...

We distinguish learning in a static environment from that in a dynamic environment to show the existence of an important interaction between the development of new technologies and human capital accumulation. Since technological progress creates a more dynamic and uncertain environment, it not...

This paper develops an economic growth model with endogenous fertility. In doing so, it provides a new explanation for the relation between fertility, economic development and human capital accumulation. The model emphasizes the role returns on human capital play in economic development through...

I develop a new measure of human capital stock that has two advantages over previous measures. First, it allows for varying costs of education across time, countries, and level of education. Second, the unit of measurement is dollars, which allows comparison of human capital stocks with other...

It is well known that turnover rates fall with employee tenure and employer size. We document a new empirical fact about turnover: Among surviving employers, separation rates are positively related to industry-level exit rates, even after controlling for tenure and size. Specifically, in a...

Entrepreneurial human capital plays a relatively more important role in intermediate income countries, but professional human capital is relatively more abundant in richer economies. Because the return to entrepreneurship is risky, individuals devote less time to the accumulation of...
