We use panel data from 1983 to 1997 for the 42 police force areas in England and Wales to test the hypothesis that legalizing abortion contributes to lower crime rates. We provide an advance on previous work by focusing on the impact of possible endogeneity of effective abortion rates with...

In this study, we use enterprise-level data to calculate estimates of labour productivity growth in the UK broadcasting sector between 1999 and 2004 and TFP growth between 1998 and 2004. We present estimates using both gross output and gross value added. We also present TFP estimates separately...

Since April 1998, the only public health clinic in McHenry County, Illinois, has required minors to obtain parental consent before receiving prescription contraceptives. This study uses data on the number of births and abortions to compare changes in birth and abortion rates among minors in the...

This paper examines potential explanations for recent declines in teenage pregnancy in England. We estimate panel data models of teenage conception, birth and abortion rates from regions in England. Although point estimates are consistent with the promotion of long acting reversible...

In this paper, we demonstrate how matching estimators can be used to evaluate policy interventions which are implemented in relatively few regions at different times. Our technique is based on translating calendar time into 'experimental time' to provide a common starting point for entry by...

Previous work based on conjectural responses of minors predicted that the 2003 Texas requirement for parental consent for state-funded birth control to minors would lead to a large increase in underage pregnancies. We use state- and county-level data to test this prediction. The latter allow us...

This paper examines potential explanations for recent declines in teenage pregnancy, in particular, the promotion of long acting reversible contraception (LARCs). We estimate models of teenage conception, birth and abortion rates using panel data from England which allows us to control for...
