Words Speak Louder Than Money
This paper reports on an experiment studying the effectiveness of two types of mechanisms for promoting trust: pecuniary and non-pecuniary as well as their mutual interaction. Our data provide evidence that both mechanisms significantly enhance trust in comparison to the standard investment game. However, we find that the pecuniary mechanism performs significantly worse than the non-pecuniary one. Our results also point to the fact that pecuniary mechanism, which depends on monetary incentives, can be counterproductive when combined with mechanism which relies primarily on psychological incentives.
