In the long run, mechanisms that enable bene\u0002cial stable strategies for information exchange can be found. This paper presents such mechanisms and speci\u0002es under which conditions it is bene\u0002cial to the agents to answer queries. We analyze a model of repeated encounters in which two agents ask each other queries over time. We present different strategies that enable information exchange, and compare them according to the expected utility for the agents, and the conditions required for the cooperative equilibrium to exist.","doi":null,"url":"https://ijcai.org/proceedings/2001/150","pdf":"https://ijcai.org/proceedings/2001/0150.pdf","markdown":"https://ijcai.org/proceedings/2001/150.md","bibtex":"https://ijcai.org/proceedings/2001/bibtex/150","volume":{"slug":"2001","title":"Proceedings of the Seventeenth International Joint Conference on Artificial Intelligence","short_title":"IJCAI 2001","url":"https://ijcai.org/proceedings/2001/","year":2001,"location":"Seattle, Washington, USA","dates":"","editors":"","isbn":"","publisher":"International Joint Conferences on Artificial Intelligence","doi_prefix":""},"section":null,"track":"","number":150,"pages":{"first":1128,"last":1133},"keywords":[],"videos":[],"references":[],"license_note":"Copyright International Joint Conferences on Artificial Intelligence."}
