This paper examines alternative forms of match bias arising from earnings imputation. Wage equation parameters are estimated based on mixed samples of workers who do and do not report earnings, the latter group being assigned earnings of donors who share some but not all the attributes of the...

Using March Current Population Survey (CPS) data, we investigate married women's labor supply behavior from 1980 to 2000. We find that their labor supply function for annual hours shifted sharply to the right in the 1980s, with little shift in the 1990s. In an accounting sense, this is the major...

Using Michigan Panel Study of Income Dynamics (PSID) data, we study the slowdown in the convergence of female and male wages in the 1990s compared to the 1980s. We find that changes in human capital did not contribute to the slowdown, since women's relative human capital improved comparably in...

College students select their majors for a variety of reasons, including expected returns in the labor market. This paper demonstrates an empirical method that links a census of U.S. degrees and fields of study with measures of the knowledge content of jobs. The study combines individual wage...

Previous findings from experimental and non-experimental studies have demonstrated that teachers differ in their effectiveness. In addition, evidence from non-experimental studies has indicated that teacher effects can last up to five years. This study used high-quality data from a four-year...

Given that previous findings on the social distribution of the effects of small classes have been mixed and inconclusive, in the present study I attempted to shed light on the mechanism through which small classes affect the achievement of low- and high-achieving students. I used data from a...

During the 1930s and 1940s, collective bargaining emerged as the workplace governance norm in much of the U.S. industrial sector. Following its peak in the 1950s, union density in the U.S. private sector fell steadily, to only 7.4 percent in 2006. Governance shifted from a formalized union norm...

Multilevel models are widely used in education and social science research. However, the effects of omitting levels of the hierarchy on the variance decomposition and the clustering effects have not been well documented. This paper discusses how omitting one level in three-level models affects...

The law of one wage does not strictly hold, nor should it be expected to hold, in contemporary labor markets. The law of one wage, however, provides a surprisingly good first approximation of the structure of U.S. wages. This generalization is drawn from research on a diverse set of topics: the...

Using 1995 - 2006 Current Population Survey and 1970 - 2000 Census data, we study the intergenerational transmission of fertility, human capital and work orientation of immigrants to their US-born children. We find that second-generation women's fertility and labor supply are significantly...
