We examine a variant of repeated Prisoner’s Dilemma whose stage game payoffs are subject to vary, and show that a payoff perturbation may strictly reduce the minimum discount factor to sustain mutual cooperation. JEL classification: C 73

Multi-robot systems involve the distribution of robotic resources and information. Being an opportunity, they require cooperation among robots so that potential advantages of distribution become effective. Cooperation requires in turn efficiently sharing information and proper coordination. This article extends previous work, regarding efficient information sharing in the context of volumetric ...

Information technologies in today’s world function as support net for sharing knowledge and information coming more important as well as promoter of mutual cooperation when it comes to development of further education of adults. Because of a passive cooperation between educational institutions and enterprises, society is still in search of approaches and methods, new information systems and tec...

Evolutionary game theory predicts that cooperation in social dilemma games is promoted when agents are connected as a network. However, when networks are fixed over time, humans do not necessarily show enhanced mutual cooperation. Here we show that reinforcement learning (specifically, the so-called Bush-Mosteller model) approximately explains the experimentally observed network reciprocity and...

Abstract The mutual agreement procedure is the main instrument available to both taxpayers and tax administrations for mitigating international double taxation arising from transfer pricing adjustments. Although it may apply cases generated by other topics, this article refers strictly its application in context of pricing. Ensuring mechanism operates as smooth possible one factors contributing...

We show that monetary exchange facilitates the transition from small to large-scale economic interactions. In an experiment, subjects chose to play an “intertemporal cooperation game” either in partnerships or in groups of strangers where payoffs could be higher. Theoretically, a norm of mutual support is sufficient to maximize efficiency through large-scale cooperation. Empirically, absent a m...

This paper examines the role of reconstruction assistance in Cambodia from 1990 to 1994. In terms of international cooperation, the case of Cambodia in the restoration period after a long civil war was an unprecedented success as a whole. This is mainly due to the continuous and consecutive runs of assistance, continuum of effective aids, which was appropriate for each stage from humanitarian a...
