Abstract: | Examined 3 research paradigms for studying the provision of step-level public goods. In the "fear plus greed" paradigm, each of the players receives a monetary endowment and then may choose independently and anonymously whether to contribute it to a monetary public good. In the "no fear" paradigm, the opportunity to free ride is maintained, but a protection from having one's contribution wasted is provided; in the "no greed" paradigm it is possible to waste one's contribution, but not to free ride. Decision policies maximizing expected utility are derived for all 3 paradigms under homogeneity and heterogeneity assumptions. Testable predictions relating "fear," "greed," and expectations about the decisions of others are derived and discussed. (28 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved) |
