Such a model captures a major form of modern online advertising where an advertiser is concerned with her\/his expected utility over a time period and her\/his type may change over time. We are interested in the incentive compatibility (IC) problem of such Bayesian mechanism. Under very mild conditions on the mechanism environments, we give a full characterization of IC via the taxation principle and show, perhaps surprisingly, that such IC mechanisms are fully characterized by the so-called auto-bidding mechanisms, which are pervasively fielded in the online advertising industry.<\/jats:p>","DOI":"10.1609\/aaai.v36i5.20450","type":"journal-article","created":{"date-parts":[[2022,7,4]],"date-time":"2022-07-04T09:21:51Z","timestamp":1656926511000},"page":"5156-5163","source":"Crossref","is-referenced-by-count":0,"title":["Characterization of Incentive Compatibility of an Ex-ante Constrained Player"],"prefix":"10.1609","volume":"36","author":[{"given":"Bonan","family":"Ni","sequence":"first","affiliation":[]},{"given":"Pingzhong","family":"Tang","sequence":"additional","affiliation":[]}],"member":"9382","published-online":{"date-parts":[[2022,6,28]]},"container-title":["Proceedings of the AAAI Conference on Artificial Intelligence"],"original-title":[],"link":[{"URL":"https:\/\/ojs.aaai.org\/index.php\/AAAI\/article\/download\/20450\/20209","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/ojs.aaai.org\/index.php\/AAAI\/article\/download\/20450\/20209","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,7,4]],"date-time":"2022-07-04T09:21:51Z","timestamp":1656926511000},"score":1,"resource":{"primary":{"URL":"https:\/\/ojs.aaai.org\/index.php\/AAAI\/article\/view\/20450"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,6,28]]},"references-count":0,"journal-issue":{"issue":"5","published-online":{"date-parts":[[2022,6,30]]}},"URL":"https:\/\/doi.org\/10.1609\/aaai.v36i5.20450","relation":{},"ISSN":["2374-3468","2159-5399"],"issn-type":[{"value":"2374-3468","type":"electronic"},{"value":"2159-5399","type":"print"}],"subject":[],"published":{"date-parts":[[2022,6,28]]}}}
