WebIncentive ratio is de- fined as the factor of the largest possible utility gain that a participant can achieve by behaving strategically, given that all other participants have their strategies unchanged. Incen- tive ratio characterizes the extent to which utilities can be in- creased by strategic manipulations. WebMoreover, it can be pinned down to in Cobb-Douglas markets. For the Leontief markets in which products are complementary, we show that the incentive ratio is at most two as well. KW - Fisher market. KW - Incentive ratio. KW - Market equilibrium.

Webcommodities, but it may exceed the upper bound from Fisher markets, which we show by means of an example. The results obtained show a sharp contrast with the findings in [7], [6]: in the Fisher market setup, incentive ratios are bounded by the small constants 2, 2 and e1/e ≈ 1.44 for linear, Leontief and Cobb–Douglas markets, respectively. Websizes. Potentially, the concept incentive ratio can have applications in other strategic settings as well. 1 Introduction Market equilibrium is a vital notion in classical economic theory. Understanding its properties and computation has been one of the central questions in Algo-rithmic Game Theory. For the Fisher market model [7], we consider ...
