VALUING THE PROTECTION OF MINIMUM INSTREAM FLOWS IN NEW MEXICO

Currently, New Mexico law does not provide any legal avenue of protecting instream flows. A change in the status quo requires that a prima facie case be made— establishing sufficient evidence of the public benefits from maintaining instream flows to warrant consideration, or standing, in future water policy deliberations. Using the contingent valuation (CV) method, we investigate the nonmarket benefits of protecting minimum instream flows in New Mexico. Results from a dichotomous choice CV telephone survey show significant nonmarket values for protecting instream flows that are sensitive to a change in scope and insensitive to a group-size reminder.Resource /Energy Economics and Policy,

Testing for Budget Constraint Effects in a National Advisory Referendum Survey on the Kyoto Protocol

In contrast to providing standard reminders about remembering household budgets, does asking survey respondents about their discretionary income and its use affect their voting responses in a national advisory referendum survey? We explore this question using U.S. household data from a unique set of multi-mode random samples (telephone and Internet surveys), and an advisory referendum concerning the Kyoto Protocol. The contingent valuation method is applied to estimate household willingness to pay (WTP) for a split-sample treatment: respondents who only received a standard reminder of household budgets (control group) versus respondents who received two mental accounting-type questions on discretionary income and its uses (treatment group). Results indicate that the treatment significantly influences voting responses and lowers estimated household WTP.budget constraint, contingent valuation, Kyoto Protocol, mental accounts, referendum, Environmental Economics and Policy,

Exploring the Beta Model Using Proportional Budget Information in a Contingent Valuation Study

Using a set of random telephone and Internet (web-based) survey samples for a national advisory referendum, we implement Beta models to handle proportional budget information, and allow for consistency in modeling assumptions and the calculation of estimated willingness to pay (WTP). Results indicate significant budget constraint effects and demonstrate the potential for Beta models in handling mental-accounting type information.Beta model

Geoengineering and the Science Communication Environment: A Cross-Cultural Experiment

We conducted a two-nation study (United States, n = 1500; England, n = 1500) to test a novel theory of science communication. The cultural cognition thesis posits that individuals make extensive reliance on cultural meanings in forming perceptions of risk. The logic of the cultural cognition thesis suggests the potential value of a distinctive two-channel science communication strategy that combines information content (“Channel 1”) with cultural meanings (“Channel 2”) selected to promote open-minded assessment of information across diverse communities. In the study, scientific information content on climate change was held constant while the cultural meaning of that information was experimentally manipulated. Consistent with the study hypotheses, we found that making citizens aware of the potential contribution of geoengineering as a supplement to restriction of CO2 emissions helps to offset cultural polarization over the validity of climate-change science. We also tested the hypothesis, derived from competing models of science communication, that exposure to information on geoengineering would provoke discounting of climate-change risks generally. Contrary to this hypothesis, we found that subjects exposed to information about geoengineering were slightly more concerned about climate change risks than those assigned to a control condition

Public Willingness to Pay for Continuous and Probabilistic Hazard Information

Investments in new weather forecasting technologies and communication products can be costly and serve the ultimate purpose of protecting life and property. The Forecasting a Continuum of Environmental Threats (FACETs) paradigm attempts to improve technology and communication through the provision of probabilistic hazard information (PHI). The research and technology necessary to produce this information requires a substantial resource investment, but the societal value of the information may outweigh the costs. This study provides an initial estimate of this value by exploring public willingness to pay (WTP) for an app that provides continuously updated, geographically situated PHI that could be utilized during a tornado event. Findings indicate that the mean WTP, in a one-time payment, for this precise hazard information product is $7.53 per person. Aggregated to the US population, the estimated value is between$901 million and $1.56 billion. These findings indicate that federal agencies and private companies are likely to generate a substantial surplus by developing these products and will contribute to improving informed decision-making and protecting lives and property

From Experts' Beliefs to Safety Standards: Explaining Preferred Radiation Protection Standards in Polarized Technical Communities

Public policy debates often involve complex, high-stakes issues in which the views of experts within scientific and technical communities play a prominent role. Disputes over appropriate governmental actions concerning global climate change, genetically modified organisms, nuclear waste disposal, cloning, and stem cell research highlight the political importance that can be attached to debates within scientific communities. Not only do these debates influence the kinds of assumed causal relationships that underlie policy alternatives (e.g., the link between CO2 concentrations in the atmosphere and global temperatures, or the dispersal patterns of pollens from genetically modified corn), but also those appointed to advisory and technical policy making positions are often chosen from the participating scientific communities. The appointment to such positions has become an increasingly contentious process; some critics contend that experts’ policy positions have trumped their scientific standing in determining appointments to important science policy boards (Revkin 2004; Mooney 2005)

Internet Versus Telephone in Contingent Valuation: Application to the Kyoto Protocol

Abstract only with list of additional readings:.ABSTRACT: Estimating the values individuals place on passively consumed goods, such as the existence of unique natural resources, can only be done by posing hypothetical questions intended to elicit statements about their willingness to pay (or be paid) for changes in these goods. These questions are administered through contingent valuation (CV) surveys. Recent years have witnessed both an expansion of the use of CV surveys, and the development of ever more sophisticated methods for conducting them. Nevertheless, a number of fundamental methodological issues remain. One barrier to faster progress in resolving them is the high cost of administering CV surveys through person-to-person, mail, or telephone interviews, which hinders the use of alternative CV instruments within a single study to determine which instruments are more reliable. This study reports on an NSF-funded research project that takes advantage of the relatively low cost of administering CV surveys through the Internet to address several methodological issues. The specific context is an examination of household willingness to pay for ratification of the Kyoto Protocol on global climate change, using a national advisory referendum format. Additionally, this study investigates the extent to which the Internet can be a replacement technology for the telephone in survey research. The experimental design includes a variety of split-sample informational treatments. Initial empricial results report on the extent to which the Internet sample (13,034 completed questionnaires) replicates a national random sample of American households conducted through random digit dialing (1,392 completed questionnaires). Comparisons are made both in terms of willingness-to-pay estimates, under different treatment conditions, and responses to a variety of background questions. For example, within the Internet sample, comparisons are made between respondents who received surveys identical to the telephone respondents, and those who were given access to a massively larger quantity of information on the science of global climate change and the Kyoto Protocol. Although the research deals specifically with contingent valuation, and therefore is of most direct interest to environmental valuation researchers, it should be of general interest to policy analysts and researchers who gather information through surveys
