This class of games is a useful abstraction for a number of realistic settings and economic situations, such as modeling relationships in social networks. To date, two main extensions of the Shapley value have been proposed for generalized characteristic function games: the Nowak-Radzik [1994] value and the S\u00e1nchez-Berganti\u00f1os [1997] value. In this context, the present article studies generalized characteristic function games from the point of view of implementation and computation. Specifically, the article makes two key contributions. First, building upon the mechanism by Dasgupta and Chiu [1998], we present a non-cooperative mechanism that implements both the Nowak-Radzik value and the S\u00e1nchez-Berganti\u00f1os value in Subgame-Perfect Nash Equilibria in expectations. Second, in order to facilitate an efficient computation supporting the implementation mechanism, we propose the Generalized Marginal-Contribution Nets representation for this type of game. This representation extends the results of Ieong and Shoham [2005] and Elkind et al. [2009] for characteristic function games and retains their attractive computational properties.\n          <\/jats:p>","DOI":"10.1145\/2665007","type":"journal-article","created":{"date-parts":[[2014,10,28]],"date-time":"2014-10-28T12:40:29Z","timestamp":1414500029000},"page":"1-35","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":6,"title":["Implementation and Computation of a Value for Generalized Characteristic Function Games"],"prefix":"10.1145","volume":"2","author":[{"given":"Tomasz P.","family":"Michalak","sequence":"first","affiliation":[{"name":"University of Oxford and University of Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Piotr L.","family":"Szczepa\u0144ski","sequence":"additional","affiliation":[{"name":"Warsaw University of Technology and Hewlett-Packard GD Poland, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Talal","family":"Rahwan","sequence":"additional","affiliation":[{"name":"Masdar Institute of Science and Technology, UAE"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Agata","family":"Chrobak","sequence":"additional","affiliation":[{"name":"University of Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Simina","family":"Br\u00e2nzei","sequence":"additional","affiliation":[{"name":"Aarhus University, Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael","family":"Wooldridge","sequence":"additional","affiliation":[{"name":"University of Oxford, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nicholas R.","family":"Jennings","sequence":"additional","affiliation":[{"name":"University of Southampton, UK and King Abdulaziz University, Saudi Arabia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2014,10,28]]},"reference":[{"volume-title":"Proceedings of the 12th International Conference on Autonomous Agents and Multiagent Systems (AAMAS). 1121--1122","author":"Aadithya K.
