“…This paper connects the literature about water-infrastructure investment, water-inventory management, and conservation-technology adoption. To our knowledge, our two-period, stochastic model is the first capacity-choice model for water projects in literature (e.g., Miltz and White, 1987;Tsur, 1990;Fisher and Rubio, 1997;Schoengold and Zilberman, 2007;Haddad, 2011;Houba et al, 2014;Xie and Zilberman, 2014) to incorporate water-use efficiency and stochastically, dynamic control of water inventories, which allows us to answer the two questions. We are therefore the first to identify water-use efficiency as a potential factor affecting water-storage investment.…”
