Does Participating in a Collective Decision Affect the Levels of Contributions Provided? An Experimental Investigation

From a purely theoretical perspective, there is no reason to expect that different levels of contributions in public goods games are associated with the same sanctioning/rewarding rule. The efficiency of a norm should be independent of its enactment procedure. On the contrary, multidisciplinary and empirical considerations suggest that individuals may behave differently, according to the level of their direct involvement. The question whether participation in norm enactment results in more contributory gap than when the same norm is received, has not been addressed in public good literature so far. Our three experiments show a behavioural regularity: participating in a normative enactment generates different contributory effects, with respect to the case when the sanctioning norm is merely received.participation, public good games, free riding
