- 주제 : Price Randomization and Favor Exchange in Imperfect Cartels

- 장소 : 다산경제관 32211호

- Abstract : We analyze the sustainability of collusion in infinitely repeated symmetric first-price procurement auctions with complete information. We show that strategies combining on-path price randomization and continuation payoff rewards for losers enable collusion in this canonical model for a wider range of discount factors than previously recognized. Our theory can explain imperfect collusive bid rotation schemes as well as observed cartel behavior in which seemingly deliberate deviations from collusive pricing happen and are followed by internal reallocations of future business rather than cartel breakdown.
