This paper offers an analytical narrative based on an assurance game with two separate populations in an evolutionary setting. In our model, Donors and Recipients are two populations; let us call them Europe and Ukraine. The donor population has two types. A proportion of this population wants...

Decentralized matching markets on the internet allow large numbers of agents to interact anonymously at virtually no cost. Very little information is available to market participants and trade takes place at many different prices simultaneously. We propose a decentralized, completely uncoupled...

In this paper I study conditions for the emergence of cooperativebehavior in a dynamic model of population interaction.The model has finitely many individuals located on a circle. The pay-off of each individual is partly based on the (local)interaction with neighbors and partly on (uniform)...

Facing the sanctions from the West since the annexation of Crimea in 2014, Russia quickly converged to a strong counter-sanction strategy. The US and the EU staggered the strengths of sanctions in turns, with the EU first imposing relatively stronger commercial sanctions first and the US...

This paper uses replicator dynamics to compare the steady states arising from two types of common property regimes - one in which over-exploiters are punished by the resource users themselves, and another where enforcement is handled by guards who collect a tax from the users. The use of guards...

We study the coevolution of cooperation, preferences, and cooperative signals in an environment where individuals engage in a signaling-extended prisoner's dilemma. We prove the existence of a cooperative equilibrium constituted by a (set of) limit cycle(s) and stabilized by the dynamic...

The likelihood of cancer emergence is highly dependent on the underlying tissue structure. This article gives evolutionary explanations for why natural selection fails to select for tissue structures that would minimize the likelihood of cancer. In a second step, a mathematical framework is...
