Using internal and public use March Current Population Survey data, we analyze trends in US income inequality (19752004). Using a multiple imputation approach where values for censored observations are imputed using draws from a Generalized Beta distribution of the Second Kind, we find that the...

We examine differences in the value of statistical life (VSL) across potential wage levels in panel data using quantile regressions with intercept heterogeneity. Latent heterogeneity is econometrically important and affects the estimated VSL. Our findings indicate that a reasonable average cost...

"Mirroring the railroad industry of the 1940's and 1950's, the trucking industry today appears to be achieving impressive productivity gains. But it is easy to confuse true productivity advances in transportation industries with changes in ton-miles per unit of input that are due simply to...

Hours worked is an important economic indicator. In addition to being a measure of labor utilization, average weekly hours are inputs into measures of productivity and hourly wages, which are two key economic indicators. However, the Bureau of Labor Statistics' two hours series tell very...

In common with many countries, the substantial United States investment in R&D is characterized by limited documentation of the nature and results of those investments (MacIlwain 2010, Marburger 2005). Despite the increased calls for reporting by key stakeholders, current data systems cannot...

This paper documents that rotation group bias - the tendency for labor force statistics to vary systematically by month in sample in labor force surveys - in the Current Population Survey (CPS) has worsened considerably over time. The estimated unemployment rate for earlier rotation groups has...

This note argues that nonparametric regression not only relaxes functional form assumptions vis-a-vis parametric regression, but that it also permits endogenous control variables. To control for selection bias or to make an exclusion restriction in instrumental variables regression valid,...

Studies of transition economy labor markets have typically relied on standard, publicly available employment and unemployment statistics. This paper analyzes microdata on detailed labor force survey responses in Russia, Romania, and Estonia to measure nonstandard, boundary forms and alternative...
