In open platforms, every firm connects to every market, while discriminatory platforms limit connections between firms and markets to improve social welfare. We provide tight bounds on the efficiency loss of both platforms; (i) that the efficiency loss at a Nash equilibrium under open access is bounded by 3\/2, and (ii) for discriminatory access platforms, we provide a greedy algorithm for optimizing network connections that guarantees efficiency loss at a Nash equilibrium is bounded by 4\/3, under an assumption on the linearity of cost functions.<\/jats:p>","DOI":"10.1145\/3152042.3152048","type":"journal-article","created":{"date-parts":[[2017,10,12]],"date-time":"2017-10-12T12:52:50Z","timestamp":1507812770000},"page":"15-17","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":7,"title":["Networked Cournot Competition in Platform Markets"],"prefix":"10.1145","volume":"45","author":[{"given":"Weixuan","family":"Lin","sequence":"first","affiliation":[{"name":"Cornell University, Ithaca, NY"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"John Z.F.","family":"Pang","sequence":"additional","affiliation":[{"name":"California Institute of Technology, Pasadena, CA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eilyan","family":"Bitar","sequence":"additional","affiliation":[{"name":"Cornell University, Ithaca, NY"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Adam","family":"Wierman","sequence":"additional","affiliation":[{"name":"California Institute of Technology, Pasadena, CA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2017,10,11]]},"reference":[{"key":"e_1_2_1_1_1","volume-title":"The Economist (US)","year":"2016"},{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-319-13129-0_2"},{"key":"e_1_2_1_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jet.2011.11.003"},{"key":"e_1_2_1_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1756-2171.2006.tb00037.x"},{"key":"e_1_2_1_5_1","doi-asserted-by":"publisher","DOI":"10.1145\/2600057.2602882"},{"key":"e_1_2_1_6_1","unstructured":"D.
