A Battle of Taste and Environmental Convictions for Ecolabeled Seafood: A Choice Experiment AgEcon
Roheim, Cathy A.; Johnston, Robert J..
This paper describes a choice experiment addressing preferences for ecolabeled seafood, in which the experimental design allows for choices among various fresh seafood products. The primary emphasis is the potential trade-off between taste (i.e., a favored species) and the presence of an ecolabel, when multiple seafood products are available.

A Battle of Taste and Environmental Convictions for Ecolabeled Seafood: A Contingent Ranking Experiment AgEcon
Johnston, Robert J.; Roheim, Cathy A..
Consumers face pressure from environmental groups to modify their seafood purchase decisions based on concerns about fisheries' production practices. Existing research provides little information indicating whether seafood consumers are willing to change purchasing behavior based on a product's environmental attributes, to the exclusion of other attributes. We describe a contingent ranking experiment addressing preferences for fresh seafood, allowing for choices among different species, some displaying an ecolabel. Results suggest consumers consider overfishing sufficiently important to contemplate changing the species of fish they buy; however, they are unwilling to choose a less-favored species based solely on the presence of an ecolabel.

Import Demand Estimation and the Generalized Composite Commodity Theorem AgEcon
Asche, Frank; Guttormsen, Atle G.; Kristofersson, Dadi; Roheim, Cathy A..
A frequently encountered problem in import demand estimation is how to account for competition between imports and domestic production. Traditionally, use of the Armington model has been a way to handle this problem. This is a disaggregate model which distinguishes commodities by country of origin with import demand determined in a separable two-step procedure. The model appears frequently in analysis of international agricultural markets. However, the Armington model relies on a set of weak separability assumptions, which several authors have shown to be highly questionable. In this paper, a new aggregation theorem, the Generalized Composite Commodity Theorem (GCCT), is applied to test whether imports can be treated as a separate group. An advantage with...

MEASURING CONSUMER PREFERENCES FOR ECOLABELED SEAFOOD: AN INTERNATIONAL COMPARISON AgEcon
Johnston, Robert J.; Roheim, Cathy A.; Donath, Holger; Asche, Frank.
An analysis of consumer preferences for seafood labeled with information about environmental production attributes is introduced into the food labeling literature. International seafood ecolabeling programs have proposed to create market-based incentives for fisheries managers to promote sustainable fisheries. We investigate differences in consumer preferences for ecolabeled seafood across the United States and Norway. Using a contingent-choice telephone survey of random households in each nation, a wide range of factors is found to influence consumers' likelihood of purchasing ecolabeled seafood. Consumer preferences differ by price premium, species, consumer group, and certifying agency. The effect of these factors often differs between the United...

PREDICTING CONSUMER PREFERENCES FOR FRESH SALMON: THE INFLUENCE OF SAFETY INSPECTION AND PRODUCTION METHOD ATTRIBUTES AgEcon
Holland, Daniel S.; Roheim, Cathy A..
A rank-ordered logit model is estimated using data collected by a mail survey of consumers in the northeastern and mid-Atlantic United States. The methodology, based on conjoint analysis, determines the average relative importance and value of three product attributes for fresh salmon (seafood inspection, production method, and price), and estimates the relative attractiveness of particular products to consumers. When used in combination with demographic data and responses to questions on perceptions, the analysis suggests market segmentations and potential marketing strategies based on the heterogeneity in preferences among consumers.

SEAFOOD SAFETY PERCEPTIONS AND THEIR EFFECTS ON ANTICIPATED CONSUMPTION UNDER VARYING INFORMATION TREATMENTS AgEcon
Roheim, Cathy A.; Kline, Jeffrey D.; Anderson, Joan Gray.
This paper identifies factors that influence consumers' seafood safety perceptions and examines how these perceptions affect consumers' anticipated consumption when consumers are provided with additional information relevant to seafood. A recursive system of equations is specified describing consumers' safety perceptions as a function of past experience with seafood, recreational harvest activities, and risk-taking behavior, and describing the influence of safety perceptions on consumers' anticipated demand response to hypothetical information concerning seafood. A telephone survey of randomly selected Rhode Island consumers provided data for the analysis.

TESTING SEPARABILITY OF JAPANESE DEMAND FOR MEAT AND FISH WITHIN DIFFERENTIAL DEMAND SYSTEMS AgEcon
Eales, James S.; Roheim, Cathy A..
The separability of meat products from fish products is investigated to gain a better understanding of Japanese consumer choices in protein demand. Rather than view fish as a single homogeneous commodity, fish and seafood are categorized into several groups of products. Separability is investigated using a demand system approach in which a generalized system of demand equations is specified and used, first to identify if any of the alternative demand structures nested within the general system are appropriate for these data, and then, conditional on those results, to test separability of meats from fish products following Moschini, Moro, and Green. Results indicate that meats and fish were separable prior to 1990; however, when examined over the entire...
