Abstract

The thesis addresses two important labor economic issues among the doctoral recipients. The first issue focuses on the impact of visa restrictions on the continual stay and career outcomes of the immigrant doctoral recipients graduating from the U.S. universities. The second issue examines the pay penalty that women with children get compared to women without children among women with Ph.D.

The first issue is analyzed using data from Survey of Earned Doctorates (SED), Survey of Doctoral Recipients (SDR), and U.S. Citizenship and Immigration Services (USCIS). The empirical analysis uses Fixed-Effects regression specification to examine the impact of wait-times for permanent residency (Green Card Status) on the migration decisions, and early and later career outcomes of foreign doctoral recipients graduating from the U.S. universities. The results indicate that for a recent immigrant doctoral recipient an additional year of wait-time decreases the probability he or she continues to stay in the U.S. by 5.5 percentage points. However, this negative impact of wait-time of immigrants’ retention in the U.S. is temporary. The longer wait-times reduce immigrants’ job mobility and probability of working outside the field of research even in the long run.

There are short-term negative effects on post-doc appointments and earnings that dissipate in the long run.

The second issue is examined using Survey of Doctoral Recipients (SDR). The empirical analysis uses Fixed-Effects regression specification to estimate (FWG) among highly skilled scientists and researchers. The results indicate that the family wage gap does exist among women with Ph.D. and is about 6.8 percent. However, most of the existing wage difference can be explained by differences in human capital characteristics and current job characteristics.
