“…While international river basin management involves social, political, economic, hydrological and ecological dimensions, this study concentrates on those factors that influence the decision to negotiate and sign a treaty regarding the management of the water. There is a sizable body of literature on water rights [e.g., see Ditwiler, 1975;Johnson et al, 1981;Ostrom, 1962;Burness and Quirk, 1980;Cummings and Nercissiantz, 1992;Dudley, 1992] as well as on apportionment and river basin management [see Dinar and Loehman, 1995;Wescoat, 1995;Becker and Easter, 1998;Just and Netanyahu, 1998;Krutilla and Eckstein, 1970;Boisson de Chazournes, 1998;Hirji and Grey, 1998;Dellapenna, 1994;Wolf, 2000], yet no prior quantitative studies of international water treaty formation have been conducted.…”
