Aggregation technology of common goods and its strategic consequences: Global warming,biodiversity, and siting conflicts

Abstract. The analysis of common goods needs to look closely at the characteristics of the goods in question and the social situations in which they are provided. Different characteristics lead to different strategic constellations and therefore to different opportunities for institutional solutions to the problems of provision. Basic differences in strategic constellations can be shown clearly by employing matrix games. In this paper a particular attribute of common goods, their aggregation technology, is systematically analyzed. Three variations in this dimension are exemplified by cases from environmental policy. It becomes clear that the analysis of one specific attribute of a good will seldom suffice to predict empirical behavior. Nevertheless, rigorous game theoretic analysis provides valuable insights into the links between the characteristics of common goods and the need for institutions.
