This paper presents a convenient shortcut method for implementing the Heckman estimator of the dynamic random effects probit model using standard software. It then compares the three estimators proposed by Heckman, Orme and Wooldridge based on three alternative approximations, first in an...

The issues of persistence in the observed labour market status of men are investigated using the British Household Panel Survey for the period 1991-97. The paper extends previous work in many directions. In particular, problems of endogenous initial conditions, and unobserved heterogeneity, are...

This paper examines the extent of state dependence in individual unemployment and low paid employment and the inter-related dynamics between the two. Evidence is presented that (after controlling for unobserved heterogeneity and initial conditions) the low paid are more likely to become...

We use a quantile regression framework to investigate the degree to which work-related training affects the location, scale and shape of the conditional wage distribution. Human capital theory suggests that the percentage returns to training investments will be the same across the conditional...

Data from a range of different environments indicate that the incidence of death is not randomly distributed across families but, rather, that there is a clustering of death amongst siblings. A natural explanation of this would be that there are (observed or unobserved) differences across...
