We report on an experiment designed to explore whether a written expression of disapproval affects future levels of cooperation. In between two identical public goods games, participants play a mini dictator game that, depending on the treatment, either gives or does not give the recipient the...

Abundant evidence suggests that high levels of contributions to public goods can be sustained through self-governed monitoring and sanctions. This experimental study investigates the effectiveness of decentralized sanctioning institutions where punishment opportunities are restricted to agents...

We explore in an experiment what leads to the breakdown of partnerships. Subjects are assigned a partner and participate in a repeated public good game with stochastic outcomes. They can choose each period between staying in the public project or working on their own. There is excessive exit as...

Norms play an important role in establishing social order. The current literature focuses on the emergence, maintenance and impact of norms with regard to coordination and cooperation. However, the issue of norm-related conflict deserves more attention. We develop a general theory of "normative...

This paper concerns the regional innovation system approach. It deals with the characteristics of three regional systems, Northern Hesse, Alpes-Maritime and Jena, and focusses on each regional network of innovators. In this context the importance of the size and homogeneity of a regional pool of...

Studies analyzing the importance of intra- and inter-regional cooperation for regional innovation performance are mainly of qualitative nature and focus strongly on the positive effects that high levels of cooperation can yield. For the case of the German labor market regions and the Electrics +...

A key issue of different streams of economic literature is to determine the impact of certain dimensions of proximity on the cooperative behavior of actors and, thus, on interactive learning processes. This paper is a quantitative study on the impact of technological and geographical proximity...

This paper provides empirical tests of hypotheses of cooperative behavior provided by evolutionary approaches in the resource-based view of the firm. The influences of "technological proximity", individual incentives to cooperate and managerial tools to the choice of research partner are...

This paper investigates the possible presence of three problems in regional innovation systems (RIS): intermediation, reciprocity and compatibility. Based on ï¬rm data gathered for three different regions, Northern Hesse, Jena and Sophia Antipolis, we can show that a low propensity to...

Why is it that well-intentioned actions can create persistent conflicts? While norms are widely regarded as a source for cooperation, this article proposes a novel theory in which the emergence of norms can be understood as a bargaining process in which normative conflicts explain the finally...
