The study categorizes costs into direct losses for economic agents (540.26 million Euros), indirect losses to the regional economy (358.47 million Euros), and non-market welfare losses (761.95 million Euros). To mitigate the crisis, the Government of Catalonia implemented demand-side restrictions and supply-side measures, including the shipping of water from France and Tarragona. The authors find that demand-side constraints were significantly more cost-efficient than water transport.
