The data files have the following format:

1. For the Walker mechanism

Data files: 331wb, 331wr, 401wb, 401wr, 508wb, 508wr, 508wy

2. For the Groves-Ledyard mechanisms:

Data files:

(1) gamma=1: 404glib, 404glir, 405glib, 405glir, 506glib, 506glir, 506gliy
(2) gamma=100: 408glcb, 405glcr, 406glcb, 406glcr, 507glcb, 507glcr, 507glcy


3. Variables in the beginning of the data files are self-explanatory. The important ones are:

contrib1 - contrib5: contributions of subjects 1 to 5 in each round.

tax1 - tax5: taxes paid by subjects 1 to 5 in each round.

payoff1 - payoff5: net payoff to subjects 1 to 5 in each round.
