Oyster Demand Adjustments to Counter-Information and Source Treatments in Response to Vibrio vulnificus AgEcon
Morgan, O. Ashton; Martin, Gregory S.; Huth, William L..
A web-based contingent behavior analysis was developed to quantify the effect of both negative and positive information treatments and post harvest processes on demand for oysters. Results from a panel model indicate that consumers of raw and cooked oysters behave differently after news of an oyster-related human mortality. While cooked oyster consumers take precautionary measures against risk, raw oyster consumers exhibit optimistic bias and increase their consumption level. Further, by varying the source of a counter-information treatment, we find that source credibility impacts behavior. Oyster consumers, and in particular, raw oyster consumers, are most responsive to information provided by a not-for- profit, nongovernmental organization. Finally, post...

Disentangling Access and View Amenities in Access-Restricted Coastal Residential Communities AgEcon
Morgan, O. Ashton; Hamilton, Stuart E..
In coastal communities with uniform flood risk, amenity value is comprised of two components – view and access. Having controlled for view, it is assumed that any residual amenity value represents the benefit derived from accessing the beach for leisure/recreational purposes. However, as properties closer to the beach typically have improved viewsheds, the two amenities are highly correlated, and disentangling view and access is problematical. A spatial autoregressive hedonic model captures ease of beach access via a network distance parameter that varies independently from property viewshed, collinearity effects are mitigated, and access and view can be disentangled.
Tipo: Journal Article Palavras-chave: Beach access; Property viewshed; Spatial hedonic model; Willingness to pay; Environmental Economics and Policy; Land Economics/Use; Q51; R12; R21; R23.
