Abstract Online experiments have become a valuable research tool for researchers interested in the processes underlying cooperation. Typically, online are asynchronous, participants complete an experiment individually and matched with partners after data collection has been completed. We conducted registered report to compare asynchronous synchronous designs, where interact receive feedback rea...

A collective-risk social dilemma arises when a group must cooperate to reach a common target in order to avoid the risk of collective loss while each individual is tempted to free-ride on the contributions of others. In contrast to the prisoners' dilemma or public goods games, the collective-risk dilemma encompasses the risk that all individuals lose everything. These characteristics have poten...

We consider some classical games and show how they can arise in the context of the Internet. We also introduce some of the basic solution concepts of game theory for studying such games, and some computational issues that arise for these concepts. 1.1 Games, Old and New The Foreword talks about the usefulness of game theory in situations arising on the Internet. We start the present chapter by ...

This paper introduces a new equilibrium concept for normal form games called dependency equilibrium; it is defined, exemplified, and compared with Nash and correlated equilibria in Sections 2–4. Its philosophical motive is to rationalize cooperation in the one shot prisoners' dilemma. A brief discussion of its meaningfulness in Section 5 concludes the paper. 1. Introduction. In this note I woul...

The digital revolution of the information age and in particular the sweeping changes of scientific communication brought about by computing and novel communication technology, potentiate global, high grade scientific information for free. The arXiv for example is the leading scientific communication platform, mainly for mathematics and physics, where everyone in the world has free access on. Wh...
