“…Esteban and Dinar [] used a cooperative game theory framework to evaluate the value of cooperation in groundwater management, accounting for externalities on both the environment and other users' pumping costs. Generally, game theoretical models of groundwater exploitation represent shared aquifers as bath tubs, where changes in water levels are immediately disseminated to all users [ Negri , ; Gardner et al ., ; Rubio and Casino , ; Nakao et al ., ; Esteban and Dinar , ], or assume extremely idealized groundwater flow systems [ Loáiciga , ; Madani and Dinar , ; Dixon , ] or well‐field layouts [ Saak and Peterson , ; Saleh et al ., ; Saak and Peterson , ]. The three latter studies have shown that the hydrogeological characteristics of the aquifer and the spatial layout of the wells strongly affect common‐pool overdraft.…”
