The condition for when a price control increases consumer welfare in perfect competition is tighter than often realised.  When demand is linear, a small restriction on price only increases consumer surplus if the eleasticity of demand exceeds the elasticity of supply; with log-linear or...

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...

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...

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,...

Through an experiment this study investigates the effects that verification has on honest traders. This paper demonstrates that by reducing the scope for trust verification can have a negative effect on the behaviour of honest individuals. Specifically, the analysis shows that trustworthy agents...

In the workhorse  model of welfare economics, the elasticity of marginal utility, often denoted as η, serves simultaneously to represent aversion to risk, aversion to spatial inequality, and preferences for intertemporal substitution.  While Kreps-Porteus-Selden and Epstein-Zin preferences...

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",...

Although much research has been devoted to the impact of seller structure on market outcomes, considerably less is known about the influence of buyer structure. We examine the impact of buyer concentration on the pricing of a monopolist. Markets with both two and four buyers achieve prices well...

This paper introduces a non-parametric binary classification tree approach to inferring unobserved strategies from the observed actions of economic agents. The strategies are in the form of possibly nested if-then statements. We apply our approach to experimental data from the repeated ultimatum...
