Differences between experimental conditions of predicted cooperation probability, predicted earnings (excluding punishment endowment), and predicted probability to punish an observed defector.

Based on the fixed segments of multilevel logistic (cooperation and punishment) and linear (earnings) regression models with decisions nested in subjects and sessions. The actual models are displayed in Table B in S1 Additional analyses and study material (7,955 punishment decisions, 7,560 PDs, 252 subjects).
