Title: Willingness to pay for a clear night sky: use of the contingent valuation method
Author: Simpson, Stephanie N.
Abstract: A clear night sky is a public good, and as a public good government intervention to regulate it is justifiable. Light pollution decreases the ability to view a clear, unobstructed night sky and can have biological, human health, energy related, and scientific consequences. In order for governments to intervene more effectively, an economic analysis of light pollution with regards to costs and benefits needs to be performed. This thesis demonstrates the use of the contingent valuation method to place an economic value on light pollution. Students in the RIT community were surveyed regarding their willingness to pay for a clear night sky. The mode WTP was $0; consequently the regression analysis focuses on use of the Tobit model. The most significant factors affecting WTP were whether or not the student thought sky glow is a problem on RIT’s campus, how many years the student had been at RIT, the amount of the student’s personal income, and the amount of time the student spent outside on RIT’s campus at night. The results of this research are then applied to policy making at the local, state, and federal level. This research concludes that the contingent valuation method is applicable to the study of light pollution and development of light pollution related policies by local, state and federal policymakers, and the appropriateness of the contingent valuation method is enhanced both when respondents are informed about light pollution and its consequences, as well as with improvements in survey methodology and analysis.
