This paper presents a convenient shortcut method for implementing the Heckman estimator of the dynamic random effects probit model and other dynamic nonlinear panel data models using standard software. It then compares the estimators proposed by Heckman, Orme and Wooldridge, based on three...

Using retrospective work history data for over 50,000 men and women in Great Britain surveyed in 1975-76, the authors document the amount of vocational training occurring in a ten-year period and discuss its effects and determinants. The effects of training on occupational status are estimated...

Employees in workplaces with a closed shop get paid more than their counterparts in comparable workplaces without a closed shop. Is this pay differential a consequence of high union density or the institution of the closed ship itself? The authors' results indicate that a post-entry closed shop...

This paper presents evidence on the impact of the introduction of the National Minimum Wage using specially designed questions added to wave 9 of the British Household Panel Survey. New direct information on the basic hourly wage rate of hourly paid employees demonstrates the almost complete...

This paper evaluates the impact on employment of the UK's introduction of a minimum wage in 1999 by exploiting the geographical variation in wages, which meant that the minimum wage's 'bite' into an area's wage distribution differed considerably across the country. The results indicate that,...

This paper describes simple methods for testing various hypotheses of proportionality between the cause-specific hazards in competing risks models. It provides methods for estimating competing risks models with equality restrictions across the cause-specific hazards as single risk models. Thus,...

This note points out to applied researchers what adjustments are needed to the coefficient estimates in a random effects probit model in order to make valid comparisons in terms of coefficient estimates and marginal effects across different specifications. These adjustments are necessary because...
