Dynamics of Cooperation: Israeli Kibbutzim

Project summary: This project is aimed at understanding the dynamics of cooperation on Israeli secular and religious kibbutzim. We also sought to compare cooperation on the kibbutz with cooperation elsewhere in Israel, and how kibbutz members cooperated with fellow members and non-kibbutz members. Over 1000 common-pool resource experiments designed to measure cooperation were conducted in over 30 kibbutzim and 7 Israeli cities. I have also lived and conducted fieldwork on three kibbutzim in northern Israel.
