Existence, properties and connections with another refinement concept, introduced by the authors in a previous paper and which captures an idea of reciprocal altruism, are investigated. Examples and counterexamples are given illustrating concepts, results and links with other classical refinement concepts. <\/jats:p>","DOI":"10.1142\/s0219198908001777","type":"journal-article","created":{"date-parts":[[2008,4,28]],"date-time":"2008-04-28T07:04:25Z","timestamp":1209366265000},"page":"53-72","source":"Crossref","is-referenced-by-count":7,"title":["FRIENDLINESS AND RECIPROCITY IN EQUILIBRIUM SELECTION"],"prefix":"10.1142","volume":"10","author":[{"given":"GIUSEPPE","family":"DE MARCO","sequence":"first","affiliation":[{"name":"Dipartimento di Statistica e Matematica perla Ricerca Economica, Universit\u00e0 di Napoli Parthenope, via Medina 40, 80133 Napoli, Italia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"JACQUELINE","family":"MORGAN","sequence":"additional","affiliation":[{"name":"Dipartimento di Matematica e Statistica, Universit\u00e0 di Napoli Federico II, via Cinthia, 80126, Napoli, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"219","published-online":{"date-parts":[[2012,4,30]]},"reference":[{"key":"rf1","volume-title":"Set Valued Analysis","author":"Aubin J.
