Profile
In my research, there are four lines that are to some degree interwoven:
- Earnings of and migration among wage employees in less developed countries
- Non-farm self-employment in less developed countries
- Econometric analysis of selectivity models
- Education, job structure, and risk in labor markets in U.S. and the Netherlands
The overarching theme is a focus of the sorting mechanism that generates labor market outcomes in the form of earnings and jobs (or economic activities).
Many papers deal with a developing country labor market, using data from India, Malaysia, Cote d’Ivoire, Ghana, Peru, Tanzania, and Vietnam, but the techniques developed in these papers extend to industrial country labor markets as well.
Plans for future research deal with econometric modeling of labor market sorting models; limited dependent variable models; and a study of U.S. job-related data.
