When the Punishment Must Fit the Crime: Remarks on the Failure of Simple Penal Codes in Extensive-Form Games

Mailath, George J.; Nocke, Volker; White, Lucy - C.E.P.R. Discussion Papers - 2004

In repeated normal-form games, simple penal codes (Abreu 1986, 1988) permit an elegant characterization of the set of subgame-perfect outcomes. We show that the logic of simple penal codes fails in repeated extensive-form games. We provide two examples illustrating that a subgame-perfect outcome...

Appropriating the Commons - A Theoretical Explanation

Falk, Armin; Fehr, Ernst; Fischbacher, Urs - C.E.P.R. Discussion Papers - 2001

In this Paper we show that a simple model of fairness preferences explains major experimental regularities of common pool resource (CPR) experiments. The evidence indicates that in standard CPR games without communication and without sanctioning possibilities inefficient excess appropriation is...

Is It Trust we Model? An Attempt to Calculate the Non-Calculative

Rosenkranz, Stephanie; Weitzel, Utz - C.E.P.R. Discussion Papers - 2005

In this paper we characterize a situation in which non-calculative trust has to play a role in the decision to cooperate. We then analyse the given situation in game theoretical terms and distinguish those aspects of players’ decisions that are cooperative from those that may be interpreted as...

Behind the GATE Experiment: Evidence on Effects of and Rationales for Subsidized Entrepreneurship Training

Fairlie, Robert W; Karlan, Dean S.; Zinman, Jonathan - C.E.P.R. Discussion Papers - 2012

We use randomized program offers and multiple follow-up survey waves to examine the effects of entrepreneurship training on a broad set of outcomes. Training increases short run business ownership and employment, but there is no evidence of broader or longer run effects. We also test whether...
