Climate cooperation increasingly looks like individuals reaching out beyond traditional interactions to expand new networks, work with others to spot patterns, and take initiative to learn new complex systems; adapt these shared insights into new solutions; develop empathy, patience, and...

In everyday life, individuals interact with relatives, friends and colleagues, share ideas and passions and cooperate with others to pursue common goals. Within each social domain, individuals recognize themselves as a group member with rights and duties to observe. Understanding the importance...

Decline and break-up of institutionalized cooperation, at all levels, has occurred frequently. Some of its concomitants, such as international migration, have become topical in the globalized world. Aspects of the phenomenon have also become known as failing states. However, the focus in most...

Communication is a well-known tool to promote cooperation and pro-social behavior. In this study, we examine whether minimal communication in form of public consent with a pre-defined cooperation statement is sufficient to strengthen cooperation in groups. Within the controlled environment of a...

Conditions for the emergence of cooperation in a spatial common-pool resource game are studied. This combines in a unique way local and global interactions. A fixed number of harvesters are located on a spatial grid. Harvesters choose among three strategies: defection, cooperation, and...

We study the conditions for the emergence of cooperation in a spatial common-pool resource game. We consider three types of agents: cooperators, defectors and enforcers. The role of enforcers is to punish defectors for overharvesting the resource. Agents are located around a circle and they only...

It is well known that communication often serves as a facilitator for cooperation in static games. Yet, communication can serve entirely different purposes in dynamic settings as communication during the game may work as a means for renegotiation, potentially undermining the credibility of...

This paper introduces a two-sided methodological framework for studies on cooperation based on a new game design. Presented games are continuous prisoner's dilemma games with positive and negative presentations of an identically structured decision problem. Decision makers can choose an...

This paper investigates the impact of game presentation dependent on ethnical affiliation. Two games representing the same logical and strategical problem are introduced. Presented games are continuous prisoner’s dilemma games where decision makers can choose an individual level of cooperation...

Economic and social interactions often take place in open communities but the dynamics of the community choice process and its impact on cooperation of its members are yet not well understood. We experimentally investigate community choice in social dilemmas. Participants repeatedly choose...
