This paper provides a general formulation of the regression discontinuity (RD) design and applies this method to analyse the effects of the 1995 UK pill scare. We show that in the five months following a health warning on the third generation pill, conception rates rose by more than 7%, abortion...

We provide a critical discussion of the concept drug-related crime and review methods for estimating its volume, emphasising the importance of an appropriately defined counterfactual. We then construct new estimates for England and Wales in 2003-6, combining data from the Arrestee Survey and...

In this paper we explore the impact of birth weight on childrens cognitive and behavioural outcomes using data from the UK Millennium Cohort Study. In order to deal with the endogeneity of birth weight we propose an eliminant estimator, which exploits the availability of multiple outcomes for...
