Description: Prior work suggests that, unlike air pollution regulation, the marginal cost of ambient water pollution regulation in the United States often exceeds its marginal benefit. This paper provides some intuition, theory and empirical evidence suggesting that the typical hedonic property model -- a common revealed-preference approach in the literature valuing environmental amenities -- may tend to understate MWTP for the improved recreational opportunities that better water quality affords to local homeowners. Using the case of nutrient pollution in Tampa Bay, Florida, we estimate MWTP for water quality improvements by combining a recreation demand model with a hedonic housing model, allowing households to optimize over regional aquatic recreation opportunities (influenced by pollution in recreational waters) as well as ambient water quality very close to homes. Results indicate that homeowners have significant MWTP for both improvements in local ambient water quality and improvements in regional recreational waters. Our recreational benefit estimates are much larger than those we estimate for local amenity values, suggesting that prior hedonic studies may underestimate the value of water pollution control.
