A corrupt transaction is often the result of bargaining between the parties involved.  This paper models bribery as a double auction where a private citizen and a public official strategically interact as the potential buyer and the potential seller of a corrupt service.  Individuals differ in...

I describe a new static (sealed-bid) auction for multiple substitute goods.  As in a two-sided simultaneous multiple round auction (SMRA), bidders bid on multiple assets simultaneously, and bid-takers choose supply functions across assets.  The auction yields more efficiency, revenue,...

This paper explores the extent and nature of gender differences, by age, in household health expenditure allocation.  Using South African data, we adopt a hurdle methodology, constructing a sequence of decision stages (reporting sickness, consulting medical practitioner, incurring positive...

This paper presents a wage series for unskilled English women workers from 1260 to 1850 and compares it with existing evidence for men.  Our series cast light on long run trends in women's agency and wellbeing, revealing an intractable, indeed widening gap between women and men's remuneration...

In this paper, we consider the identification problem arising in the age-period-cohort models, as well as in the extended chain ladder model.  We propose a canonical parametrization based on the accelerations of the trends in the three factors.  This parametrization is exactly identified.  It...

This paper examines the relationship between norm enforcement and in-group favouritism behaviour.  Using a new two-stage allocation experiment with punishments, we investigate whether in-group favouritism is considered as a social norm in itself or as a violation of a different norm, such as...
