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",...

Tenured public officials such as judges are often thought to be indifferent to the concerns of the elctorate and, as a result, potentially lacking in discipline but unlikely to pander to public opinion.  We investigate this proposition empirically using data on promotion decisions taken by...

Economies are so high dimensional and non-constant that many features of models cannot be derived by prior reasoning, intrinsically involving empirical discovery and requiring theory evaluation.  Despite important differences, discovery and evaluation in economics are similar to those of...

Even in scientific disciplines, forecast failures occur.  Four possible states of nature (a model is good or bad, and it forecasts well or badly) are examined using a forecast-error taxonomy, which traces the many possible sources of forecast errors.  This analysis shows that a valid model can...

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,...

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...

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...

Why is it that couples who have a son or whose last child is a son earn higher conditional income?  To solve this curious case we tell a detective story: evidence of a phenomenon to be explained, a parade of suspects, a process of elimination from the enquiry, and then the denouement.  Given...
