We study network formation with <em>n players</em> and link cost <em>α </em> 0. After the network is built, an adversary randomly deletes one link according to a certain probability distribution. Cost for player <em>ν</em> incorporates the expected number of players to which <em>ν</em> will become disconnected. We focus on...</em>

The replicator-mutator dynamics is a set of differential equations frequently used in biological and socioeconomic contexts to model evolutionary processes subject to mutation, error or experimentation. The replicator-mutator dynamics generalizes the widely used replicator dynamics, which...

We report experimental results on the minority of three-game, where three players choose one of two alternatives and the most rewarding alternative is the one chosen by a single player. This coordination game has many asymmetric equilibria in pure strategies that are non-strict and...

The paper presents a complete information model of bidding in second price sealed-bid and ascending-bid (English) auctions, in which potential buyers know the unit valuation of other bidders and may spitefully prefer that their rivals earn a lower surplus. Bidders with spiteful preferences...

This paper reports an experiment evaluating the effect of gift giving on building trust. We have nested our explorations in the standard version of the investment game. Our gift treatment includes a dictator stage in which the trustee decides whether to give a gift to the trustor before both of...

This paper introduces a model of social preferences featuring a single parameter representing an individual's disposition to share resources with others. The parameter reacts to observed behavior of others in a clearly defined manner. Therefore, the model allows the numerical analysis of...

This paper provides experimental evidence on how players predict end-game effects in a linear public good game. Our regression analysis yields a measure of the relative importance of priors and signals on subjects’ beliefs on contributions and allows us to conclude that, first, the weight of...

The World's nations have yet to reach a truly effective treaty to control the emission of greenhouse gases.  The importance of compatibility with private incentives of individual countries has been acknowledged (at least by game theorists) in designing climate policies for the post-Kyoto...

<em></em> <em>Games</em> has received help from many individuals since its inaugural issue in 2009. We are especially grateful to the following 146 referees for their great support of <em>Games</em> during the past two years. [...]

Negli ultimi tempi, fra gli studiosi dei processi di formazione delle scelte pubbliche è in corso un interessante dibattito volto ad individuare le tecniche più appropriate per gestire in maniera efficace (ovvero in tempi rapidi e garantendo la stabilità e la durevolezza delle decisioni o...
