1) Standard bargaining protocols are vulnerable to "curious" agents who seek to obtain information through negotiation rather than reach an agreement. 2) The authors propose three extensions to bargaining to address this: agents must declare reserve prices to a third party beforehand, negotiations are limited to a set number of rounds, and cancelling results in agents receiving/paying their reserve prices. 3) These extensions incentivize agents to be honest about their reserve prices and reach agreements before deadlines to avoid costs, making the protocol more robust to curiosity. Experiments show the extensions improve outcomes for secretive agents while limiting benefits to curious ones.
