Institutions and Behavior: Experimental Evidence on the Effects of Democracy
通过新颖实验发现，民主选择的政策比外生强加的政策更能促进合作，且排除了选择效应，表明民主制度本身会直接影响行为，对政策干预的可推广性有启示。
A novel experiment is used to show that the effect of a policy on the level of cooperation is greater when it is chosen democratically by the subjects than when it is exogenously imposed. In contrast to the previous literature, our experimental design allows us to control for selection effects (e.g., those who choose the policy may be affected differently by it). Our finding implies that democratic institutions may affect behavior directly in addition to having effects through the choice of policies. Our findings have implications for the generalizability of the results of randomized policy interventions.
