This study presents a modified version of the repeated discounted prisoners’ dilemma with long and short-run players. In our setting a short-run player does not observe the history that has occurred before he was born, and survives into next phases of the game with a probability given by the current action profile in the stage game. Thus, even though it is improbable, a short-run player may liv...

This supplement contains extended formal results for Daley and Sadowski (2016) (henceforth DS16). Specifically, §S.1 establishes that in Prisoners’ Dilemma (PD) games, the model of DS16 is logically distinct from three models that employ well-known forms of other-regarding preferences: altruism (Ledyard, 1995; Levine, 1998), inequity aversion (Fehr and Schmidt, 1999), and reciprocity (Rabin, 19...

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

A prior signalling stage is added to the prisoner’s dilemma and the overall population involved is divided into a number of subpopulations. Evolution involves both local and global imitation—so that the process is formally one of “group selection.” A subpopulation that is not signalling and defecting against one and all can be invaded by two “secret handshake” mutants. A subpopulation that is c...

The recent literature on oligopolistic third-degree price discrimination has been primarily concerned with rival firms' incentives to acquire customer-specific information and the consequences of such information on firm profitability and welfare. This literature has taken mostly a static view of the interaction between competing firms. In contrast, in this paper we investigate the impact of cu...

s the criminal justice system grew, attention began to focus on the fact that many of the people being placed nder criminal justice supervision were parents. Throughout the 1990s, researchers, child and prisoner dvocates, practitioners, and policy makers scrambled to learn what happens to children when their parents are rrested and incarcerated. It was during this period that the Child Welfare ...
