註釋Agricultural producers make investment decisions based on beliefs about future returns. This article investigates how changes in beliefs about input availability affects the adoption of conservation practices. We develop a theoretical model to examine how a producer's beliefs about water shortages influence investment in more efficient irrigation technologies. We then use publicly available data on water rights and irrigated cropland to empirically identify the impact of changing beliefs about water availability on conservation decisions. We leverage a natural experiment in Colorado in which a period of severe drought and institutional change in the early 2000s led to an exogenous shock to expectations for some water right holders. We estimate that producers who experience unprecedented increases in the curtailment of their water right convert 11% more land to a more efficient irrigation technology on average. We also present evidence that adoption rates are driven more by changes in surface water availability than groundwater. This analysis provides useful insight into the role of beliefs in incentivizing adaptation to increasing water scarcity in irrigated agriculture.
