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.

Characterizing Spatial Pattern in Ecosystem Service Values when Distance Decay Doesn’t Apply: Choice Experiments and Local Indicators of Spatial Association AgEcon
Johnston, Robert J.; Ramachandran, Mahesh; Schultz, Eric T.; Segerson, Kathleen; Besedin, Elena Y..
Stated preference analyses commonly impose strong and unrealistic assumptions in response to spatial welfare heterogeneity. These include spatial homogeneity or continuous distance decay. Despite their ubiquity in the valuation literature, global assumptions such as these have been increasingly abandoned by non-economics disciplines in favor of approaches that allow for spatial patchiness. This paper develops parallel methods to evaluate local patchiness and hot spots in stated preference welfare estimates, characterizing relevant patterns overlooked by traditional approaches. The analysis draws from a choice experiment addressing river restoration. Results demonstrate shortcomings in standard treatments of spatial heterogeneity and insights available...

Context Similarity and the Validity of Benefits Transfer: Is the Common Wisdom Correct? AgEcon
Johnston, Robert J..
Choice experiments are designed to account for variations in environmental resources and site characteristics, as well as potential implications of these variations for willingness to pay. This may render choice experiment results highly suitable for benefits transfer. It is unclear, however, whether the flexibility of choice experiments renders the similarity of study and transfer sites less critical for transfer validity. Drawing from identical choice experiments conducted in different Rhode Island communities, this model assesses the extent to which error in function-based benefits transfer is related to the similarity of communities across a variety of observable dimensions. Results suggest that site similarity, at least across some dimensions,...

CONTINGENT VALUATION FOCUS GROUPS: INSIGHTS FROM ETHNOGRAPHIC INTERVIEW TECHNIQUES AgEcon
Johnston, Robert J.; Weaver, Thomas F.; Smith, Lynn A.; Swallow, Stephen K..
Despite the many important uses (and potential abuses) of focus groups in survey design, the CV literature presents few guidelines to aid moderators in their interaction with focus group participants. This paper draws on the theory and practice of ethnographic interviewing to introduce general guidelines that can improve focus groups as an aid to CV research. The proposed guidelines illustrate types of questions that should reduce speculation and moderator-introduced bias in focus group responses, and improve the correspondence between focus group responses and actual behavior. The paper illustrates these ethnographic guidelines through a CV application concerning watershed resources.

Farmland Preservation and Differential Taxation: Evaluating Optimal Policy Under Conditions of Uncertainty AgEcon
Johnston, Robert J..
Differential property tax policy for farmland is often set under conditions of uncertainty and limited information regarding landowners' objective functions. This study examines optimal differential tax policy for a parcel of agricultural land facing uncertain development, identifying instances in which common farmland taxation policies may be non-optimal. Optimal tax rates are characterized given three possible causes of uncertain development: exogenous offers from developers, tax-related reductions in landowner wealth, and a combination of these factors. Model results indicate that underlying causes of uncertain development are critical when seeking to assess the optimality of differential taxation policies, and the use of a single, time-invariant...

Is Willingness to Pay for Farmland Preservation Transferable Across States? Evidence from a Choice Experiment AgEcon
Johnston, Robert J.; Duke, Joshua M..
In stated preference assessments of farmland preservation programs, respondents are often told that preservation will occur within a given scale-e.g., community, state, county-but do not know the specific location of parcels in question. Hence, welfare estimates may be available for different scales, providing numerous avenues for benefit transfer. This paper provides a systematic assessment of transfer error, contrasting methods for the transfer of farmland preservation values across states and jurisdictional scales. The data are drawn from choice experiments conducted simultaneously in two different states and at two different scales. Results suggest that transfers across state outperform transfers across scale, and that simpler methods often...

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...

Optimizing Farmland Preservation Choices Across Communities and Jurisdictional Scales: To What Extent are Amenity Values and Selection Criteria Transferable? AgEcon
Johnston, Robert J.; Duke, Joshua M.; Kukielka, Jessica B..
This paper assesses the potential for function based benefit transfer to inform farmland preservation policy, with emphasis on distinctions between welfare estimation and policy prioritization. Data are drawn from a parallel choice experiments implemented in six communities and statewide in Connecticut. The analysis provides a range of empirical results of potential significance for policy, but two findings are of particular relevance. First, results suggest that transfer errors in WTP for farmland preservation are comparable to those found in other policy contexts, even across similar sites. Results also suggest, however, that welfare based policy rankings are strongly correlated across sites, even when dollar denominated transfer errors are substantial....

Preferences for Residential Development Attributes and Support for the Policy Process: Implications for Management and Conservation of Rural Landscapes AgEcon
Johnston, Robert J.; Swallow, Stephen K.; Bauer, Dana Marie; Anderson, Christopher M..
The rural public may not only be concerned with the consequences of land management; residents may also have systematic preferences for policy instruments applied to management goals. Preferences for outcomes do not necessarily imply matching support for the underlying policy process. This study assesses relationships among support for elements of the policy process and preferences for management outcomes. Preferences are examined within the context of alternative proposals to manage growth and conserve landscape attributes in southern New England. Results are based on (a) stated preferences estimated from a multi-attribute contingent choice survey of rural residents, and (b) Likert-scale assessment of strength of support for land use policy tools....

STATED PREFERENCES AND LENGTH OF RESIDENCY IN RURAL COMMUNITIES: ARE DEVELOPMENT AND CONSERVATION VALUES HETEROGENEOUS? AgEcon
Johnston, Robert J.; Swallow, Stephen K.; Bauer, Dana Marie.
Newer residents of rural, urban-fringe communities are often assumed to have preferences for the development and conservation of rural lands that differ from those of longer-term residents. The existing literature offers little to verify or quantify presumed preference shifts. This paper provides a systematic, quantitative examination of whether stated preferences for development and conservation tradeoffs differ according to length of residency in a rural community, and explores implications of these findings for assumptions regarding development and conservation preferences. Results are based on stated preferences estimated from a multi-attribute contingent choice survey of Rhode Island rural residents. Heterogeneity-according to length of town...

Systematic Influences of Policy Implementation and Conservation Agents on Willingness to Pay for Land Preservation AgEcon
Duke, Joshua M.; Johnston, Robert J..
Economists frequently assess willingness to pay (WTP) for land preservation outcomes independent of information regarding policy implementation. The public, however, may not only be concerned with the consequences of land management, but also may have systematic preferences for policy procedures applied to achieve management goals. This paper examines relationships between WTP for land preservation outcomes and attributes of the policy process, considering stated preferences for farm and forest preservation in two Northeastern states. The approach departs from traditional welfare assessments in that it does not constrain attributes of the policy process to be utility-neutral. Results indicate that utility is influenced by policy process attributes, even...

Systematic Variation in Willingness to Pay for Agricultural Land Preservation and Implications for Benefit Transfer: A Meta-Analysis AgEcon
Kukielka, Jessica B.; Johnston, Robert J.; Duke, Joshua M..
Despite prior studies examining willingness to pay for farmland preservation there has been no quantitative, systematic analysis of findings across the literature. This paper presents the first statistical meta-analysis of farmland preservation values. Results confirm systematic variations in willingness to pay, with value surfaces corresponding to theoretical expectations. Findings also provide significant insight into the potential for valid meta-analytic, function based benefit transfer. Results suggest, for example, that transfer validity is critically dependent on jurisdictional scale. Transfer errors are modest for community scale farmland preservation, but large for state scale preservation policies in which per acre welfare estimates are small.

THE INFLUENCE OF SPATIAL LAND USE PATTERNS ON RURAL AMENITY VALUES AND WILLINGNESS TO PAY FOR GROWTH MANAGEMENT: EVIDENCE FROM A CONTINGENT CHOICE SURVEY AgEcon
Johnston, Robert J.; Bauer, Dana Marie; Swallow, Stephen K..
This paper reports on a contingent choice study in which residents of a rural Rhode Island community were asked to express their preferences for packages of growth management outcomes, where surveys presented both spatial and non-spatial attributes of growth management outcomes. Survey results provide insight on the extent to which estimated willingness to pay (WTP) for marginal changes in specific landscape features or land uses may be influenced by spatial considerations. Results also characterize the potential impact of spatial context on public preferences and WTP for coordinated packages of growth management outcomes.

Validating Hypothetical Surveys Using Binding Public Referenda: Implications for Stated Preference Valuation AgEcon
Johnston, Robert J.; Joglekar, Deepak P..
This study presents a criterion validity test in which stated choices are compared to subsequent binding referendum votes. The study is distinguished by identical hypothetical and actual choice contexts, and results that show no evidence of hypothetical bias. Results suggest a number of possibilities for amelioration of hypothetical bias.

Valuing Farmland Protection with Choice Experiments That Incorporate Preference Heterogeneity: Does Policy Guidance Depend On the Econometric Fine Print? AgEcon
Johnston, Robert J.; Bergstrom, John C..
Although mixed logit models are common in stated preference applications, resulting welfare estimates can be sensitive to minor changes in specification. This can be of critical relevance for policy and welfare analysis, particularly if policymakers are unaware of practical implications. Drawing from an application to agricultural conservation in Georgia, this paper quantifies the sensitivity of welfare estimates to common variations in mixed logit specification and assesses practical implications for policy guidance. Results suggest that practitioners may wish to reevaluate modeling and reporting procedures to reflect the welfare and policy implications of common but often unnoticed variations in model specification.

WHO ARE RESOURCE NONUSERS AND WHAT CAN THEY TELL US ABOUT NONUSE VALUES? AN APPLICATION TO COASTAL WETLAND RESTORATION AgEcon
Johnston, Robert J.; Opaluch, James J.; Mazzotta, Marisa J.; Magnusson, Gisele.
This paper assesses the potential for incomplete definitions of resource use to influence estimates of nonuser WTP, and whether uses underlying certain use values may escape measurement using standard mechanisms applied to distinguish resource users from nonusers. Empirical results are drawn from a stated preference analysis involving coastal wetland restoration.

Willingness to Pay for Water Quality Improvements in the United States and Canada: Considering Possibilities for International Meta-Analysis and Benefit Transfer AgEcon
Johnston, Robert J.; Thomassin, Paul J..
This paper presents a multinational meta-analysis estimated to identify systematic components of willingness to pay for surface water quality improvements, developed to support benefit transfer for Canadian policy development. Metadata are drawn from stated preference studies that estimate WTP for water quality changes affecting aquatic life habitats—a type of study with few Canadian examples. The goals of this paper are to assess the properties of a multinational (United States/Canada) meta-analysis compared to a single-country (U.S.) analog; illustrate the potential information that may be derived as well as the analytical challenges; and assess the performance of resulting meta-functions for benefit transfer.
