Cooperation under risk and ambiguity
(2016-12)

Is there a hidden cost of imposing a minimum contribution level for public good contributions?

Social preferences in childhood and adolescence - A large-scale experiment

(2010-08)
We experimentally investigate, using a dictator game, if the effects of windfall and earned
endowments on behavior differ between men and women genders. In line with previous
