| We attempt to value health risks by combining traditional demand impact analysis with direct elicitation of individuals’ risk perceptions of food safety. We examine the impact of multiple risks of related goods on consumption of a risky good. We argue that the consumption of a risky good depends on both its absolute risk level and its relative risks to other risky goods. Seafood consumption in eastern North Carolina was studied. We elicited, in a survey, individual perceived risks as reference points to derive the economic value of reducing health risk in seafood consumption. Revealed and stated data were combined to trace out demand changes in response to absolute and relative risk reductions. Our results show that seafood consumption is affected by the... |

| This paper argues that the widespread belief that discrete contingent valuation (CV) questions yield substantially larger estimates of the mean (and the median) willingness to pay (WTP) for nonmarket environmental resources in comparison to estimates from open-ended CV questions is unfounded. A set of Monte Carlo experiments estimate the factors influencing the performance of WTP estimates based on discrete response models. Most of the error in the WTP estimates arises from the specification errors that are common in most of the empirical models used in the literature. These experiments suggest models based on choices where WTP is dominated by non use (or passive use) values are likely to have smaller errors than where large use values influence these... |

| Policy makers often face the problem of evaluating how water quality affects a region's economic well-being. Using water clarity as a measure of the degree of eutrophication levels (as a lake becomes inundated with nutrients, water clarity decreases markedly), analysis is performed on sales data collected over a six-year period. Our results indicate that water clarity has a significant effect on prices paid for residential properties. Effects of a one-meter change in clarity on property value are also estimated for an average lake in four real estate market areas in New Hampshire, with effects differing substantially by area. Our findings provide state and local policy makers a measure of the cost of water quality degradation as measured by changes in... |

We elicit, in a survey, the individual perceived risks as the reference points to derive the economic value of reducing health risk in seafood consumption. Revealed and stated data are combined to trace out demand changes in response to absolute and relative risk reductions. Our results show that seafood consumption is affected by the perceived absolute risk and by the relative risk to poultry, which confirms that individuals react to the multiple risks in a nonlinear way--as... |

| New policy is being developed that incorporates not only innovative means of disposal, including the integration of source reduction and recycling, but also innovative approaches to funding disposal of municipal solid waste (MSW). This study was conducted to determine if a higher marginal price for MSW disposal affected per capita waste generation in New Hampshire towns, how the existence of a pay-as-you-throw (PAYT) program influenced per capita MSW generation, and to attempt to determine which towns were most likely to adopt a PAYT program in the future. The results showed that average household size, existence of a capital improvement plan, and marginal price to dispose of waste were statistically significant influences, regardless of the variation of... |
