摘要

We (i) study wage-experience profiles and obtain measures of returns to potential work experience using data from about 24 million individuals in 1,084 surveys and census samples across 145 countries; (ii) show that workers in developed countries accumulate twice as much human capital at work as those in developing countries; (iii) use a simple accounting framework to find that the contribution of work experience and education to human capital accumulation and economic development might be equally important; and (iv) employ panel regressions to investigate how changes in the returns over time correlate with several factors such as economic recessions, transitions, and human capital stocks.
