This paper studies how competition between groups affects cooperation. In the control condition, pairs of subjects play an indefinitely repeated Prisoner's Dilemma game without external competition. In the treatment, two pairs compete against each other. No monetary rewards are tied to winning,...

Experiment participants in a social dilemma game choose cooperation over defection, even though neither is more beneficial. High levels of cooperation cannot be explained by favorable labels for actions, collusion, k-level reasoning, quantal response behavior, or misplaced optimism about others'...

We characterize 'Games of Altruistic Cooperation' as a class of games in which cooperation leaves the individual and the group of decision-makers worse off than defection, but favors individuals outside the group. An example is climate change mitigation. In this context, we experimentally...

We explore a broad class of values for cooperative games in characteristic function form, known as compromise values. These values efficiently allocate payoffs by linearly combining wellspecified upper and lower bounds on payoffs. We identify subclasses of games that admit nontrivial efficient...

The Taxation Game is a cooperative game played between a set of countries I = {1, . . . , n} admitting the operation of a multinational enterprise (MNE, "the firm" ) within their jurisdiction. The firm, when operating within the territory of a subgroup S ⊆ I of countries (a coalition) will...

This study explores the dynamics of international strategic learning alliances through the lens of game theory, incorporating complexity and cooperative game theories to develop a model of organizational evolution. Using simulations and network resources, we examine 1200 cases to assess the...

An effective way to foster cooperation is to monitor behaviour and sanction freeriding. Yet, previous studies have shown that cooperation quickly declines when sanctioning mechanisms are removed. We test if explicitly expressing trust in players' capability to maintain cooperation after the...

Two consistent findings from the experimentally literature on public good games are that cooperation declines over time and cooperation is lower in countries with weak institutions. These findings, however, are primarily based on experiments in Europe, North America and Asia. There is little...

The prisoner's dilemma (PD) is arguably the most important model of social dilemmas, but our knowledge about how a PD's material payoff structure affects cooperation is incomplete. In this paper we investigate the effect of variation in material payoffs on cooperation, focusing on one-shot PD...

Algorithms play an increasingly important role in economic situations. These situations are often strategic, where the artificial intelligence may or may not be cooperative. We study the deter-minants and forms of algorithmic cooperation in the infinitely repeated prisoner’s dilemma. We run a...

We propose and characterize weighted-egalitarian values for cooperative transferable utility games. Each weighted-egalitarian value divides the worth of the grand coalition into two parts and allocates them through equality and proportionality based on exogenous player weights. We characterize...
