ABSOLUTE VERSUS RELATIVE RISK PERCEPTIONS: AN APPLICATION TO ECONOMIC VALUES OF SEAFOOD SAFETY AgEcon
Huang, Ju-Chin; Haab, Timothy C.; Whitehead, John C..
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 is studied. 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...

MEASURING USE VALUE FROM RECREATION PARTICIPATION AgEcon
Whitehead, John C..
Recreation demand studies have traditionally utilized a two-step valuation method, estimating condtional recreation participation probabilities and then intensity of use decisions. These two steps of analysis are combined to estimate the use value of natural resource recreation sites. The purpose of this paper is to provide a method by which use value can be estimated solely from the participation decision. The one-step resource valuation method allows estimation of use values from coefficients of the logistic regression recreation participation equation. The benefits of the method are the reduced data and effort required to value natural resource areas.

Risk Valuation in the Presence of Risky Substitutes: An Application to Demand for Seafood AgEcon
Huang, Ju-Chin; Haab, Timothy C.; Whitehead, John C..
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...

The Provision Point Mechanism and Scenario Rejection in Contingent Valuation AgEcon
Groothuis, Peter A.; Whitehead, John C..
The provision point mechanism mitigates free-riding behavior in economic experiments. In two contingent valuation method surveys, we implement the provision point design. We ask respondents for their perceptions about the success of the provision point mechanism. We find that respondents who believe that the provision point would not be met are more likely to say no to a contingent valuation dichotomous choice question. The scenario rejection that arises may result in biased willingness-to-pay estimates.

The Welfare Effects of Pfiesteria-Related Fish Kills: A Contingent Behavior Analysis of Seafood Consumers AgEcon
Parsons, George R.; Morgan, Ash; Whitehead, John C.; Haab, Timothy C..
We use contingent behavior analysis to study the effects of pfiesteria-related fish kills on the demand for seafood in the Mid-Atlantic region. We estimate a set of demand difference models based on individual responses to questions about seafood consumption in the presence of fish kills and with different amounts of information provided about health risks. We use a random-effects Tobit model to control for correlation across each observation and to account for censoring. We find that (i) pfiesteria-related fish kills have a significant negative effect on the demand for seafood even though the fish kills pose no known threat to consumers through sea-food consumption, (ii) seafood consumers are not responsive to expert risk information designed to reassure...

WILLINGNESS TO PAY FOR AGRICULTURAL RESEARCH AND EXTENSION PROGRAMS AgEcon
Clifford, William B.; Hoban, Thomas J.; Whitehead, John C..
The North Carolina Agriculture Survey was designed to estimate the willingness to pay for agricultural research and extension programs. We find that North Carolina households are willing to pay between $218 and $401 million for food production programs and between $251 and $698 million for water quality programs annually. We find evidence of divergent validity and differences in the willingness to pay estimates from the single-bound and multiple-bound data.
