Gamba, Astrid - 2011

A common feature of the literature on the evolution of preferences is that evolution favors nonmaterialistic preferences only if preference types are observable at least to some degree. We argue that this result is due to the assumption that in each state of the evolutionary dynamics some...

All but one free ride when wealth effects are small

Silvestre, Joaquim - In: SERIEs : Journal of the Spanish Economic Association 3 (2012) 1/2, pp. 201-207

Quasilinear preferences on a public good and a numeraire good are limits of preferences where both goods are normal. The set of equilibria of the voluntary contribution (or private provision) game is easily characterized under quasilinearity by: top valuators aggregately contribute their common...

Stochastically stable implementation

Cabrales, Antonio; Serrano, Roberto - In: SERIEs : Journal of the Spanish Economic Association 3 (2012) 1/2, pp. 59-72

Restricting attention to economic environments, we study implementation under perturbed better-response dynamics (BRD). A social choice function (SCF) is implementable in stochastically stable strategies of perturbed BRD whenever the only outcome supported by the stochastically stable strategies...

Giving versus taking : a "real donation" comparison of warm glow and cold prickle in a context-rich environment

Grossman, Philip Johnson; Eckel, Catherine C. - 2012

This paper revisits the question of framing and the provision of public goods. It also addresses the question, is giving in Dictator Games an expression of altruism or an artefact of experimentation? What is unique about this paper is that we employ a real donationʺ lab experiment in a...

The refined best-response correspondence in normal form games

Balkenborg, Dieter; Hofbauer, Josef; Kuzmics, Christoph - 2012

This paper provides an in-depth study of the (most) refined best reply correspondence introduced by Balkenborg, Hofbauer, and Kuzmics (2012). An example demonstrates that this correspondence can be very different from the standard best reply correspondence. In two-player games, however, the...

Robustness to strategic uncertainty

Andersson, Ola; Argenton, Cédric; Weibull, Jörgen W. - 2012

In games with continuum strategy sets, we model a player's uncertainty about another player's strategy, as an atomless probability distribution over the other player's strategy set. We call a strategy profile (strictly) robust to strategic uncertainty if it is the limit, as uncertainty vanishes,...

Approximation results for discontinuous games with an application to equilibrium refinement

Carbonell-Nicolau, Oriol; MacLean, Richard P. - 2011

We provide approximation results for Nash equilibria in possibly discontinuous games when payoffs and strategy sets are perturbed, and compare these conditions to those considered in the related literature. We then prove existence results for a new "finitistic" infinite-game generalization of...
