In this note, we present a novel computerized real effort task based on moving sliders across a screen which overcomes many of the drawbacks of existing real effort tasks.  The task was first developed and used by us in Gill and Prowse (2009).  We outline the design of our "slider task",...

Ultimatum games have been extensively used in experimental studies. By studying the consequences that restrictions shared by ultimatum games have in subject`s behaviour, this paper argues that some results are falsified by design constraints. This paper also presets a taxonomy of certification,...

This paper provides a positive theory about the contractual form of procurement contracts under cost uncertainty. However, while the cost of manufacture is uncertain it can be reduced by an amount depending on the extent of effort exerted by the agent. The effort exerted by the agent is not...

This paper examines experimental evidence relating to herd behaviour in situations when subjects can learn from each other, and can delay their decision. Subjects acted rationally, gaining from observational learning, despite penalties for delay. Cascades were ubiquitous and reverse-cascades...

We experimentally investigate the extent to which social obervability of one's actions and the possibility of social non-monetary judgment affect the decision to engage in rule breaking behavior.  We consider three rule bfeaking scenarios - theft, bribery and embezzlement - in the absence of...

This paper is empirical study, using new experimental data, of repeated game strategies in trust games; its goal is to identify strategies that people use in repeated games. We develop a strategy inference method that maps observed actions to a set of best fitting unobserved repeated game...
