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.
