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...

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...

The classical trinity of tests is used to check for the presence of a tremble in economic experiments in which the response variable is binary. A tremble is said to occur when an agent makes a decision completely at random, without regard to the values taken by the explanatory variables. The...
