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...

In public goods experiments, stochastic choice, censoring and motivational heterogeneity give scope for disagreement over the extent of unselfishness, and whether it is reciprocal or altruistic. We show that these problems can be addressed econometrically, by estimating a finite mixture model to...

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...
