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...

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...

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,...

We exploit a rich administrative panel data-set for cohorts of Economics students at a UK university in order to identify causal effects of class absence on student performance. We utilise the panel properties of the data to control for unobserved heterogeneity across students and hence for...

We examine the link between a mother's autonomy – the freedom and ability to think, express, act and make decisions independently – and the nutritional status of her children. We design a novel statistical framework that accounts for cultural and traditional environment, to create a measure...

In the context of the UK Government’s ambitious programme of medical school expansion, it is important to have an understanding of how the medical school admissions process works, and with what effects. The issue is also relevant for the Schwartz Review (2004) into higher education admissions....

From individual-level data for nine entire cohorts of undergraduate students in UK universities, we estimate the probability that an individual will drop out of university during their first-year. We examine the 1984-85 to 1992-93 cohorts of students enrolling full-time for a three or four-year...

From individual-level longitudinal data for two entire cohorts of medical students in UK universities, we analyse the probability that an individual student will "drop out" of medical school prior to the successful completion of their studies. We examine the cohort of students enrolling for a...
