Contributions to public goods simulated in economists' laboratoryexperiments have two peculiarities from the perspective ofstatistical modelling. There is a variety of contributor behaviours(Ledyard, 1995), suggestive perhaps of separate classes ofindividuals, and contributions are doubly...

Lying to participants offers an experimenter the enticing prospect of making "others' behaviour" a controlled variable, but is eschewed by experimental economists because it may pollute the pool of subjects. This paper proposes and implements a new experimental design, the Conditional...

Since homo sapiens is a social animal, one might expect human nature - the set of psychological propensities with which our species is naturally endowed - to equip human beings to live in social groups. In this chapter, we consider the implications of this idea for economics and game theory. We...

In public goods experiments, stochastic choice, censoring, and motivational heterogeneity allow experimentalists to differ over the extent of unselfishness, and whether it is reciprocal or altruistic. These problems are addressed econometrically by estimating a finite mixture model to isolate...

Experimental dictator games have been used to explore unselfish behaviour. Evidence is presented here, however, that subjects’ generosity can be reversed by allowing them to take money from a partner. Dictator game giving therefore does not stem from orthodox social preferences. It can be...

Coordination on focal points in one shot games can often be explained by team reasoning, a departure from individualistic choice theory. However, a less exotic explanation of coordination is also available based on best-responding to uniform randomisation. We test the team reasoning explanation...

We apply propensity score matching (PSM) to the estimation of household motor fuel purchase quantities, to tackle problems caused by infrequency of purchase. The results are compared to an alternative, regression-based, imputation strategy using the infrequency of purchase model (IPM). Using...

Lying to participants offers an experimenter the enticing prospect of making “others' behaviour†a controlled variable, but is eschewed by experimental economists because it may pollute the pool of subjects. This paper proposes and implements a new experimental design, the Conditional...

A neglected critique of social science laboratories alleges that they implement phenomena different to those supposedly under investigation. The critique purports to be conceptual and so invulnerable to a technical solution. I argue that it undermines some economics designs seeking to implement...
