Incentive Ratios of Fisher Markets


We consider a Fisher market where agents submit their own utility functions and money endowments to the market maker, who, upon receiving every agent‘s report, derives market equilibrium prices and allocations of the items. While agents may benefit by misreporting their private information, we show that the percentage of improvement by a unilateral strategic play, called incentive ratio, is rather limited--it is less than 2 for linear markets and at most 1.445 for Cobb-Douglas markets. We further prove that both ratios are tight.
