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...

We use panel data from local authorities in England between 1998 and 2004 to examine the differential impact of increased access for teenagers to emergency birth control (EBC) at pharmacies on teenage pregnancies and sexually transmitted infections (STIs). We estimate both...

Robert Axelrod's seminal round-robin computer tournaments for the repeated prisoner's dilemma have been hailed as the explanation of the evolution of cooperation. In this paper, Axelrod's results are systematically re-examined in the light of new insights about computer simulations. In...

A significant body of theoretical literature has argued that popular interest in sporting contests between teams is heavily influenced by how difficult it is to predict the result <italic>ex-ante</italic>. Empirical research has, however, been unable to reach a consensus on the magnitude of uncertainty of...

Although trading in securities in conventional financial markets on the basis of inside information is restricted by law, the rules against such trading in better markets are rather more ambiguous. It is argued in this paper that, since insider trading in betting markets imposes a cost on the...

This paper analyses investments by firms into areas of corporate social responsibility, focussing on the decision by firms whether or not to invest in compliance with voluntary environmental standards. Theoretical predictions of the compliance decision are tested using discrete time survival...
