Self-protection by well owners from potential nitrate contamination is modeled as an optimal stopping problem, where an owner sequentially tests the well and uses the test results to update his or her subjective probability that the well is contaminated. Because nitrate concentrations in a well...

Sample nonresponse and selection biases that may occur in survey research such as contingent valuation applications are discussed and tested. Correction mechanisms for these types of biases are demonstrated. Results indicate the importance of testing and correcting for unit and item nonresponse...
