Abstract

In an online multilevel public goods experiment, we implement four treatments where we gradually increase the marginal per capita return of the global public good. First, we find evidence of an increase in the contribution to the global good (levelling-up effect). Secondly, subjects fund their higher contribution to the global good by reducing their contribution to the local good (substitution effect) rather than by increasing total contribution, i.e., the sum of their contributions to the local and the global good (marginal crowding-in effect). Moreover, we observe that total contribution increases as a consequence of the mere introduction of the global good (categorical crowding-in effect). Finally, we observe that subjects continue to contribute to both public goods even when they are dominated in terms of costs and returns.

多层次公共物品博弈:升级、替代与挤入效应
在一个在线多级公共产品实验中,我们实施了四种处理方法,逐步提高全球公共产品的边际人均回报。首先,我们发现了对全球利益贡献增加的证据(升级效应)。其次,主体通过减少对本地商品的贡献(替代效应)而不是通过增加总贡献(即对本地商品和全球商品贡献的总和)来为其对全球商品的更高贡献提供资金(边际挤入效应)。此外,我们观察到,总贡献增加的结果仅仅是全球利益的引入(分类拥挤效应)。最后,我们观察到,即使在成本和回报方面占主导地位,主体也会继续为这两种公共产品做出贡献。

期刊介绍: The Journal aims to present research that will improve understanding of behavioral, in particular psychological, aspects of economic phenomena and processes. The Journal seeks to be a channel for the increased interest in using behavioral science methods for the study of economic behavior, and so to contribute to better solutions of societal problems, by stimulating new approaches and new theorizing about economic affairs. Economic psychology as a discipline studies the psychological mechanisms that underlie economic behavior. It deals with preferences, judgments, choices, economic interaction, and factors influencing these, as well as the consequences of judgements and decisions for economic processes and phenomena. This includes the impact of economic institutions upon human behavior and well-being. Studies in economic psychology may relate to different levels of aggregation, from the household and the individual consumer to the macro level of whole nations. Economic behavior in connection with inflation, unemployment, taxation, economic development, as well as consumer information and economic behavior in the market place are thus among the fields of interest. The journal also encourages submissions dealing with social interaction in economic contexts, like bargaining, negotiation, or group decision-making. The Journal of Economic Psychology contains: (a) novel reports of empirical (including: experimental) research on economic behavior; (b) replications studies; (c) assessments of the state of the art in economic psychology; (d) articles providing a theoretical perspective or a frame of reference for the study of economic behavior; (e) articles explaining the implications of theoretical developments for practical applications; (f) book reviews; (g) announcements of meetings, conferences and seminars.
