Precipitation is higher in one river-basin while water productivity is higherin the other. Water transfer increases productivity in the recipient basin, but may causeenvironmental damage in the donor basin. The recipient faces a trade-off between payingthe price of the water transfer, or investing in alternative water supplies to achieve ahigher usable water capacity. We analyze the design of this transfer using a dynamicmodeling approach, which relies on non-cooperative game theory, and compare solutionswith different information structure (Nash open-loop, Nash feedback, Stackelberg) withthe social optimum. We first assume that the equilibrium between supply and demanddetermines the optimal transfer price and amount. We show that, contrary to the staticcase, in a realistic dynamic setting in which the recipient uses a feedback informationstructure the social optimum will not emerge as the equilibrium solution. We then studydifferent leadership situations in the water market and observe that the transfer amountdecreases towards a long-run value lower than the transfer under perfect competition,which in turn lays below the social optimum. In consequence, the water in the donor’sriver-basin river converges to a better quality in the presence of market power. Finally, wenumerically compare our results to the Tagus-Segura water transfer described in Ballestero(2004). Welfare gains are compared for the different scenarios. We show that in all dynamicsettings, the long-run transfer amount is lower than in Ballestero’s static model. Further,we show that the long-run price settles at a lower level than in Ballestero’s model, but isstill higher than the average cost-based price determined by the Spanish government.
