The decision when to provide services by the public sector and when to use the private sector is a fundamental one. The economic literature emphasises that the efficiency of the mechanisms of delivery will depend on the contractual nature of what can be achieved by the parties and the political...

Much of the literature on diversity assumes that individuals have an exogenous "taste for discrimination". In contrast with this approach, we build a model where preferences over the nature of one's community are derived indirectly, and arise because the composition of the community determines...

The glass ceiling is one of the most controversial and emotive aspects of employment in organisations. This paper provides a model of the glass ceiling that exhibits the following features that are frequently thought to characterise the problem: (i) there is a lower number of female employees in...

This paper discusses proposed governance reforms of legal services markets. The model distinguishes between a status quo position supported by a system of professionally enforced collective reputation and forms of governance based more squarely on market mechanisms. We identify a number of...

In the 'glass ceiling' debate there appear to be two strongly held and opposing interpretations of the evidence, one suggesting it is really the result of gender differences and the other that there is discrimination by gender. This paper provides an economic theory of the glass ceiling and one...

We study Nature's trade-off when endowing people with the cognitive ability to distinguish between different time periods or different prizes. Our key premise is that cognitive ability is a scarce resource, to be deployed only where and when it really matters. We show that this simple insight...

We consider a society with informed individuals (adults) and naive individuals (children). Adults are altruistic towards their own children and possess information that allows to better predict the behavior of other adults. Children benefit from adopting behaviors that conform to the social norm...

We build a model where introspection matters - i.e., people rationally form expectations about others using the lens of their own attitudes. Since trustworthy individuals are more "optimistic" about people than opportunists, they are less afraid to engage in market-based exchanges, where they...

We consider a model of securities issues where the quality of securities is private information to the issuer, and firms of higher quality are more reluctant to issue securities than low quality firms. We show that, when the issuer directly trades with investors, market breakdown may occur. This...
