Experimental studies of the WTP-WTA gap avoid social trading by implementing an incentive compatible mechanism for each individual trader. We compare a traditional random price mechanism and a novel elicitation mechanism preserving social trading, without sacrificing mutual incentive...

We define and experimentally test a public provision mechanism that meets three basic ethical requirements and allows community members to influence, via monetary bids, which of several projects is implemented. For each project, participants are assigned personal values, which can be positive or...

Based on an axiomatically derived provision rule allowing community members to endogenously determine which, if any, public project should be provided, we perform experiments where (i) not all parties benefit from provision, and (ii) the projects' "costs" can be negative. In the tradition of...

We experimentally manipulate the efficiency of trust and reciprocity in a modified Investment Game. The aim of our manipulation is to test whether reciprocity is mainly affected by payoff consequences of trust or by intentions underlying it. We find that intentions matter and that consequences...

We experimentally investigate how affective processes influence proposers' and responders' behaviour in the Ultimatum Game. Using a dualsystem approach, we tax cognitive resources through time pressure and cognitive load to enhance the influence of affective processes on behaviour. We find that...
