Punishment credibility and cooperation in public good games

Dataset from a public good experiment with punishment opportunities. It consists of three treatment conditions that vary the probability with which punishment decisions are carried out (p). The treatment variable takes "P100" (p=1), "P80" (p=0.8), and "P20" (p=0.2). The dataset records contribution decisions, punishment decisions, first-stage and final-period payoffs, and socioeconomic variables extracted from subjects.
