How Well Do U.S. Western Water Markets Convey Economic Information?
利用资产定价模型评估美国西部水权市场的效率，检验永久水权转让价格是否充分反映了长期回报、利率和风险溢价。
An efficient market implies that potential gains from trade are fully captured. Achieving this requires a well-functioning market where prices reflect all available information. In the case of water rights markets, this implies that the permanent water rights transfer price reflects the sum of discounted returns to this asset (i.e., the lease price), the market interest rate, and a risk premium that reflects potential future water scarcity. The purpose of this study is to assess the efficiency of western U.S. water markets by using the asset pricing model to measure how well prices reflect long-run returns to permanent water rights.
