A theoretical model is adopted in order to explain incentives and actual safety behaviour for drivers, pedestrians and other road users which do not utilise motorised vehicles. A road user's outcome is supposed to be dependent on her individual actions and cares decided upon by other individuals...

Previous research has highlighted the importance of strong heterogeneity for the successful evolution of cooperation in games governed by pairwise interactions. Here we determine to what extent this is true for games governed by group interactions. We therefore study the evolution of cooperation...

Established already in the Biblical times, the Matthew effect stands for the fact that in societies rich tend to get richer and the potent even more powerful. Here we investigate a game theoretical model describing the evolution of cooperation on structured populations where the distribution of...

The aim of this paper is to interpret the relationships between information networks and the armed conflict in Colombia. Over a period of paramilitary violence networks of informants were used with a strategic purpose. In fact, the paramilitaries were preparing each slaughter counting...

This paper analyses the optimal combination of costly and costless messages that a Sender uses in a signaling game if he is able to choose among all equilibrium communication strategies. We provide a complete characterization of the equilibrium that maximizes the Sender's ex ante expected...

We consider a signaling game where White students and Black students compete for college admissions. All students have psychic costs that vary with their intrinsic ability and the level of performance. But Black students in addition face a cultural or psychological cost which varies with...

The efficiency of institutionalized punishment is studied by evaluating the stationary states in the spatial public goods game comprising unconditional defectors, cooperators, and cooperating pool-punishers as the three competing strategies. Fine and cost of pool-punishment are considered as the...

Public participation ranging from information sharing to decision-making remains central to equitable and effective water management. Involving directly and indirectly affected individuals in decision-making facilitates trust and can establish partnerships. It also helps ensure that vital...

We show that, in a multi-agent contract setting, the principal can effectively rule out tacit collusion among agents (i.e., “bad” equilibrium) by posting permanent job openings to an external labor market. That is, a simple “market-like” employment mechanism can yield collusion-proof...

Collaborators often invest unequal resources towards a common good. Without agreement on sharing that good, collaboration might devolve into parallel, possibly competitive, individual efforts. Reaching agreement requires bargaining. Before bargaining, collaborators independently decide how much...
