We apply a recently proposed method to disentangle unobserved heterogeneity from risk in returns to education. We replicate the original study on US men and extend to US women, UK men and German men. Most original results are not robust. A college education cannot universally be considered an...

We consider the problem of testing for a structural break in the spatial lag parameter in a panel model (spatial autoregressive). We propose a likelihood ratio test of the null hypothesis of no break against the alternative hypothesis of a single break. The limiting distribution of the test is...

This paper studies the labor supply contributions to individual and family earnings inequality during the period of rising wage inequality in the early 1980's. Working couples have positively correlated labor market outcomes, which are almost entirely attributable to permanent factors. An...

This study examines the extent and influence of occupational licensing in the U.S. using a specially designed national labor force survey. Specifically, we provide new ways of measuring occupational licensing and consider what types of regulatory requirements and what level of government...

Obesity is a rising epidemic. This research study shows that the scale of such a phenomenon is due to the effects of peers on individual weight-related behaviour, as well as to the limits on dynamic behavior imposed by habits. We estimate a dynamic linear-in-means model to analyse the importance...
