Research on Socioeconomic Impacts of Chronic Wasting Disease (CWD) in Alberta AgEcon
Adamowicz, Wiktor L.; Arnot, C.; Boxall, Peter C.; Dridi, Chokri; Goddard, Ellen W.; Jordan, M.; Forbes, K.; Laate, K.; Myshaniuk, K.; Parlee, B.; Petigara, M.; Unterschultz, James R.; Zimmer, N..
This report summarizes a series of projects undertaken by staff and students in the Department of Rural Economy which examine various socio-economic aspects of chronic wasting disease and its effect on a range of stakeholders in Alberta. The four projects included exploring impacts on the cervid farming industry, hunters, the general Albertan public, and certain Aboriginal groups. General results from these studies are presented with references that provide a more thorough analysis and discussion.

Modeling Congestion as a Form of Interdependence in Random Utility Models AgEcon
Boxall, Peter C.; Hauer, Grant; Adamowicz, Wiktor L..
This paper develops a theory of interdependent utility functions in examining congestion in recreation demand equilibria. The notion is examined empirically through the development of congestion forecasting functions which individuals use to sort themselves among a set of recreation sites. These forecasts are used in site choice models estimated on revealed preference information. An interesting outcome of this exercise is that recreation site attribute changes, which are projected to provide positive utility, may in fact generate negative utility if the effect of the change on congestion is jointly considered.

Non-market Valuation Biases Due to Aboriginal Cultural Characteristics in Northern Saskatchewan: The Values Structures Component AgEcon
Murray, Eloise C.; Adamowicz, Wiktor L.; Beckley, Thomas M.; MacDonald, Darla Hatton; Just, Lesley; Luckert, Martin K.; Phillips, William.
Current non-market valuation techniques have been developed based on assumptions about values held within the Eurocentred culture. Contentions between cultures over natural resources are hypothesized to occur because of differences in held values resulting in different values being assigned to the resources in question. This study measured the held values of an Aboriginal band in Northern Saskatchewan as the first dimension of a non-market valuation study of natural resources. These held value structures are presented noting differences by age and gender and in comparison with the local Non-Aboriginal community and another Aboriginal group in northern Alberta.

NOT PLAYING THE GAME: NON-PARTICPATION IN REPEATED DISCRETE CHOICE MODELS AgEcon
von Haefen, Roger H.; Adamowicz, Wiktor L..
This paper develops and empirically evaluates alternative econometric strategies for accounting for non-participation - repeated choice of the same alternative or same type of alternative - in data sets that are typically analyzed within the repeated discrete choice framework. Random coefficient single and double hurdle variants of the repeated discrete choice model are developed and applied to stated preference data. The empirical results suggest that significant statistical improvements in fit can arise with the single and double models relative to more traditional models. However, similar to Haab and McConnell's (1996) findings in the context of count data models, these gains are diminished when the analyst accounts for unobserved heterogeneity...

Integrating Routine, Variety Seeking and Compensatory Choice in a Utility Maximizing Framework AgEcon
Adamowicz, Wiktor L.; Swait, Joffre.
Given the large number of choices that consumers make each day it seems likely that they will generally adopt decision strategies that minimize cognitive effort, particularly with low price products such as most items found in a supermarket. One such strategy may be to simply choose what has been chosen in the past, i.e. to fall into a pattern of routine choices or decisions. In contrast, there may be preferences for variety in markets for low price, highly differentiated goods. We develop a conceptual and empirical model of routine choice, and the factors that result in transitions to two strategies other than routine selection, to wit, utility maximizing choice among available alternatives and a variety seeking strategy. The empirical approach we employ...

ANALYSIS OF "DON'T KNOW" RESPONSE TO REFERENDUM CONTINGENT VALUATION QUESTIONS AgEcon
Haener, Michel K.; Adamowicz, Wiktor L..
This paper considers the treatment of "don't know" (DK) responses to referendum contingent valuation questions. The determinants of DK responses are empirically analyzed using a data set from a survey of old growth forest valuation. It is found that DK respondents possess unique characteristics that differentiate them from Yes and No respondents. These findings do not support the most common treatments of DK responses that are currently used. Responses to an open-ended question included in the survey are used to provide further insight into the preferences of DK respondents.

Consumers' Responses to the Potential Use of Bovine Somatotrophin in Canadian Dairy Production AgEcon
Kuperis, Peter; Veeman, Michele M.; Adamowicz, Wiktor L..
The responses of a random sample of consumers to the use of bovine somatotrophin (BST) in milk production were elicited using a stated preference methodology. A multinomial logit model of consumer choice was developed and tested to analyse consumers' choices of milk with varying characteristics of fat content, price, freshness and BST treatment. Welfare calculations for a representative consumer indicate welfare losses with the introduction of BST which are not fully offset by preferred milk attributes such as reduced price or increased freshness levels. Welfare losses were slightly less for a male than a female consumer and were less for consumers with higher levels of income and education. Losses were greatest when a representative consumer was denied...

Are Country of Origin and Non-GM Premiums Invariant to Experimental Auction Structure? AgEcon
Volinskiy, Dmitriy; Adamowicz, Wiktor L.; Veeman, Michele M.; Srivastava, Lorie.
A revealed preference auction experiment is used to elicit values for two attributes, one relating to genetic modification and the other to country of origin of the food product, canola oil. A premium for a non-GM canola oil is found to approximate CA$0.4 to $0.6 per litre. Auction format effects are found and hypotheses as to why these may occur are suggested.

THE INFLUENCE OF ATTRIBUTE CUTOFFS ON CONSUMERS’ CHOICES OF A FUNCTIONAL FOOD AgEcon
Ding, Yulian; Veeman, Michele M.; Adamowicz, Wiktor L..
This study investigates evidence of non-compensatory preferences by incorporating attribute cutoffs into the modeling of consumer choices in the context of food with health-related attributes (omega-3 content) that may be associated with fortification or may result from genetic modification (GM). Data for this study were collected through a nation-wide internet-based survey drawn from a representative panel of Canadian households maintained by a major North American marketing firm. In addition to querying respondents on their perceptions and attitudes regarding food and health, choices of canola oils are elicited using a stated choice experiment in which product alternatives are identified based on attributes of price, country of origin, omega-3 content...

BIODIVERSITY AND NATURE-BASED TOURISM: THE POTENTIAL FOR SUSTAINABLE DEVELOPMENT IN UGANDA AgEcon
Naidoo, Robin; Adamowicz, Wiktor L..
The benefits of nature-based tourism to biodiversity conservation are often presumed but rarely quantified. The relative value placed on attributes of nature parks is unknown, as is the contribution of biodiversity to tourists' willingness to visit a particular protected area. We surveyed tourists and foreign residents in Uganda to determine how preferences for particular protected areas are formed. We evaluated tourists' demand for elevated biodiversity levels (increased numbers of bird species seen), relative to other protected areas attributes. As the number of bird species increased, tourists demonstrated increased willingness to visit a protected area, independently of all other factors. We used these results to evaluate a revenue-maximising park...

An Economic Evaluation of Woodland Caribou Conservation Programs in Northwestern Saskatchewan AgEcon
Tanguay, Mark; Adamowicz, Wiktor L.; Boxall, Peter C..
The purpose of this study was to identify the values Saskatchewan residents place on their Woodland Caribou conservation programs. Using contingent valuation methods, individual values for maintaining caribou numbers within Millar Western-NorSask Forest Management Licence agreement area were estimated. Using these value estimates, societal benefits were estimated for the implementation of a woodland caribou maintenance program within the forest licence agreement area. The data used in this study were collected using a mailout survey to Saskatchewan residents. Two contingent valuation formats were used, the opened ended willingness to pay and the dichotomous choice. A number of question structures were employed in order to judge the sensitivity of the...

BSE and the Dynamics of Beef Consumption: Influences of Habit and Trust AgEcon
Ding, Yulian; Veeman, Michele M.; Adamowicz, Wiktor L..
This study relates habit persistence and trust to recurring food safety incidents in the context of a series of three BSE incidents in Canada. We examined the dynamics of monthly beef expenditure shares of a sample of Canadian households for monthly time periods during year 2002 through 2005 using micro level panel data which followed meat expenditures by Canadian households before and after the first three BSE cases which were discovered in 2003 and 2005. Our results suggest that households’ reactions to the first three BSE events followed a similar general pattern: households reduced beef purchase expenditures following the discovery of BSE but these expenditures subsequently recovered, suggesting that concern diminished over time. Following the first...

Consumers' Preferences for GM Food and Voluntary Information Acquisition: A Simultaneous Choice Analysis AgEcon
Veeman, Michele M.; Hu, Wuyang; Adamowicz, Wiktor L..
Previous research studies directed at the influence of information on consumers' preferences and choices of food in the context of genetically modified (GM) food assume that information is exogenous, in that this is provided to consumers from external sources. Information made available to consumers is also typically treated as being received and processed. Other literature and observation suggests that these two features tend not to apply in practice. Using data from a choice experiment on consumers' choices for genetically modified food in which respondents were able to voluntarily access information, this study allows information to be endogenous; consumers' product choices and information access decisions are examined within a simultaneous choice...

An Experimental Investigation of the Impact of Fat Taxes: Prices Effects, Food Stigma, and Information Effects on Economics Instruments to Improve Dietary Health AgEcon
Cash, Sean B.; Lacanilao, Ryan D.; Adamowicz, Wiktor L.; Raine, Kim.
There is currently no published research on how food taxes may affect consumer behaviour when the imposition of the tax itself may be considered a source of consumer information. The work undertaken here seeks to address this gap in the literature by using experimental methods to enhance understanding on the joint effects of price changes induced by a fat tax and the stigma associated with the application of the tax. First, we conduct an interdisciplinary literature review (drawing from economics, psychology, and health promotion) and theoretical investigation of the impact of stigma on economic choice behaviours. We then employ Attribute-Based Stated Choice Methods (ABSCM) to elicit consumer response to fat tax scenarios that rely only on price changes,...

CHOICE AND TEMPORAL WELFARE IMPACTS: DYNAMIC GEV DISCRETE CHOICE MODELS AgEcon
Swait, Joffre; Adamowicz, Wiktor L.; van Bueren, Martin.
Welfare economics is often employed to measure the impact of economic policies or externalities. When demand is characterized by discrete choices, static models of consumer demand are employed for this type of analysis because of the difficulty in estimating dynamic discrete choice models. In this paper we provide a tractable approach to estimating dynamic discrete choice models of the Generalized Extreme Value (GEV) family that addresses many of the problems identified in the literature and provides a rich set of parameters describing dynamic choice. We apply this model to the case of recreational fishing site choice, comparing dynamic to static versions. In natural resource damage assessment cases, static discrete choice models of recreational site...
