This article employs the contingent valuation method (CVM) to measure the nonmarket value of preservation of the Ste. Genevieve Academy, a quasi-public good. This study represents a new application of the CVM featuring a historical resource. As such, the authors explore the validity and reliability of this application of the method. Construct validity tests bared on economic theory and the reliability test of internal consistency are conducted. The authors find evidence that the CVM can be a useful approach for measuring the nonmarket value of quasi-public goods such as historical resources. The authors also illustrate how the CVM can be used for policy analysis of preservation of historical sites.
