Influence of generalized trust on Canadian consumers’ reactions to the perceived food risk of three recurring BSE cases
Provedor de dados: 31
Autores: Ding,   Yulian; Veeman,   Michele M.; Adamowicz,   Wiktor L.
Interest in the influence of trust on consumers’ responses to food risk perceptions associated with Canadian instances of BSE motivates this study, in which Canadian households’ expenditures on fresh meat are assessed in the context of the first three recurring risk events in which bovine spongiform encephalopathy (BSE) was found to have affected Canadian cows. Engel Curve analysis focusing on the dynamics of the monthly meat expenditure shares for a selected sample of 437 Canadian households for 2002 through 2005 is applied based on data on household expenditures for meat purchased by a national sample of Canadian households from the Nielsen Homescan® Canadian panel, supplemented by survey responses on BSE risk perceptions and measures of trust. Two sets...

THE INFLUENCE OF ATTRIBUTE CUTOFFS ON CONSUMERS’ CHOICES OF A FUNCTIONAL FOOD
Provedor de dados: 31
Autores: 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...

Consumers' Preferences for GM Food and Voluntary Information Acquisition: A Simultaneous Choice Analysis
Provedor de dados: 31
Autores: 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...

ASSESSING IMPACTS OF ENVIRONMENTAL CHANGE ON ABORIGINAL PEOPLE: AN ECONOMIC EXAMINATION OF SUBSISTENCE RESOURCE USE AND VALUE
Provedor de dados: 31
Autores: Dosman,   Donna; Haener,   Michel K.; Adamowicz,   Wiktor L.; Marois,   Juanita; Boxall,   Peter C.
The report describes the research design, data collection and preliminary analysis of an economic assessment of non-timber resource use by Aboriginal People in Northwest Saskatchewan.  The project is designed to develop methods of valuing resource use by Aboriginal People so that these values can be incorporated into forest resource management decisions and to evaluate the impact of forest management actions on the economic well-being of Aboriginal People living in the region.  Data on non-timber resource use are collected and spatially explicit economic models are developed in order to construct estimates of behavioral change and value associated with changes in the environment and landscape (through forestry, access, or other landscape changes).

THE EFFECTS OF TRADE LIBERALIZATION ON THE ENVIRONMENT: AN EMPIRICAL STUDY
Provedor de dados: 31
Autores: McCarney,   Geoffrey R.; Adamowicz,   Wiktor L.
We seek to contribute to the emerging economic theory on trade, the environment and development.  Using panel data across countries, econometric models are estimated to predict the effects of openness on organic water pollutant (BOD) and carbon dioxide (CO2) emissions.  Results indicate that freer trade significantly increases emissions of both pollutants, thus reducing environmental quality.  Moreover, the panel nature of the data allows heterogeneity across countries to be controlled, so that comparisons can be made of how different national characteristics influence the environmental impact of freer trade. By testing the effects of democratic versus autocratic governance, it is found that while greater democracy can induce significant reductions in BOD...

MODELING RECREATION SITE CHOICE: DO HYPOTHETICAL CHOICES REFLECT ACTUAL BEHAVIOR?
Provedor de dados: 31
Autores: Haener,   Michel K.; Boxall,   Peter C.; Adamowicz,   Wiktor L.
This study examines the ability of revealed preference (RP), site-specific stated preference (SP), transferred SP, and various joint RP-SP models to predict aggregate and individual recreation site choice behavior in a holdout sample.  For two statistical comparisons, the site-specific RP model provided the most accurate predictions of individual choices.  However, the transferred SP model, applied directly or estimated jointly with the RP data, performed best in three aggregate and one individual prediction tests and second best in the other individual prediction comparisons.  In every test examined the transferred SP models outperformed the site-specific SP models.  This result is traced to the method used to collect the hypothetical choice data (mail...

We assess Canadian’s risk perceptions for genetically modified (GM) food and probe influences of socio-economic, demographic and other factors impinging on these perceptions.  An internet-administered questionnaire with two stated choice split-sample experiments that approximate market choices of individual grocery shoppers is applied to elicit purchase behavior from 882 respondents across Canada. Data are collected to assess the influence on respondents’ choices for a specific food product (bread) of 1) product information which varies in content and by source and 2) information provided through labeling.  These data also enable: a) analysis of trade-offs made by consumers between possible risks associated with GM ingredients and potential health or...

Delving into Choice Internals: A Joint Discrete Choice/Attribute Rating Model
Provedor de dados: 31
Autores: Gubanova,   Tatiana; Volinskiy,   Dmitriy; Adamowicz,   Wiktor L.; Veeman,   Michele M.
Multi-attribute modeling has rapidly progressed from being a novelty to becoming a widely used tool of economic research. When both choice and attribute ratings data are available, a model that makes joint use of both offers informative inference opportunities. In the present study we develop a joint model which utilizes both choice and ratings data, allows for scale usage heterogeneity, is robust to violations of utility continuity and completeness. The model is used to obtain WTP estimates for genetically-modified content and country-of-origin attributes in an survey-based study of Canola oil labeling. The median survey respondent's WTP for non-GM Canola oil was found to be CA$0.92/liter. The median WTP for non-specification of GM content was found to be...

NOT PLAYING THE GAME: NON-PARTICPATION IN REPEATED DISCRETE CHOICE MODELS
Provedor de dados: 31
Autores: 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...

GENETICALLY MODIFIED FOODS:  CONSUMERS' ATTITUDES AND LABELING ISSUES
Provedor de dados: 31
Autores: Veeman,   Michele M.; Adamowicz,   Wiktor L.
Consumers' attitudes to genetically modified (GM) food ingredients and their reactions to and preferences for labeling of GM food are topical issues for Canadian food policy and are the subjects of this study. This project included several components. The first of these was an assessment of public attitudes to biotechnology and to GM food based on evidence from polls and other studies. These show increasing awareness and some increase in wariness of GM food, in Canada and elsewhere. In the second component of the project, analysis of   survey data on Alberta consumers' preferences for different policy approaches to GM food was undertaken. This analysis indicates a preference by Alberta residents for GM food policy to emphasize the provision of more...

Economic Uncertainties in Valuing Reductions in Children's Environmental Health Risks
Provedor de dados: 31
Autores: Hoffmann,   Sandra A.; Krupnick,   Alan J.; Adamowicz,   Wiktor L.
The recognition that environmental hazards can affect children differently and more severely than adults has provoked growing concern in industrialized nations about the impact of environmental pollution on children's health. In this paper, commissioned by the OECD, we are charged with examining "economic uncertainties" associated with valuing the benefits of environmental policies that reduce risk to children's health. We examine two sources of uncertainty in benefits estimation: forecasting uncertainty and modeling uncertainty. We explore how these sources of uncertainty affect the use of standard economic and non-economic approaches to the valuation of health benefits. These include willingness-to-pay measures, cost-of-illness and human-capital...

HABIT FORMATION AND VARIETY SEEKING IN A DISCRETE CHOICE MODEL OF RECREATION DEMAND
Provedor de dados: 31
Autores: Adamowicz,   Wiktor L.
The recreational site choice decision modeled in most economic analyses seldom contains previous experience with the site as a characteristic or attribute.  A rational dynamic model is used to incorporate previous experience with the site in a model of the choice of recreation sites.  Based on the comparison of dynamic and static models, it is apparent that dynamic elements influence choice.  The use of previous consumption as an attribute (either in a naïve or rational form) is an improvement over static models of choice.  In welfare analysis, this effect may be a significant factor.  For example, a change in prices or quality attributes may have a much larger impact on those individuals who have developed habits.

BIODIVERSITY AND NATURE-BASED TOURISM: THE POTENTIAL FOR SUSTAINABLE DEVELOPMENT IN UGANDA
Provedor de dados: 31
Autores: 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...

‘Pocket and Pot’: Hypothetical Bias in a No-Free-Riding Public Contribution Game
Provedor de dados: 31
Autores: Gubanova,   Tatiana; Adamowicz,   Wiktor L.; McMillan,   Melville.
Hypothetical bias arises when values which people say they place on a good or service differ systematically from the values people reveal for the same good or service through actual, binding economic transactions. Studies of hypothetical bias with respect to public goods often use charitable contributions or other relatively unique goods and these studies employ a variety of mechanisms to elicit the stated and revealed values. This study proposes the inclusion of a free-rider barring random dictatorship mechanism in the standard public contribution game to investigate the issue of bias when a public good involves immediate monetary returns to subjects. Steps are taken to make the game have the look and feel of a real-world tradeoff between private...

CHOICE AND TEMPORAL WELFARE IMPACTS: DYNAMIC GEV DISCRETE CHOICE MODELS
Provedor de dados: 31
Autores: 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...

Consumers' Responses to the Potential Use of Bovine Somatotrophin in Canadian Dairy Production
Provedor de dados: 31
Autores: 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...

IMPLICATIONS OF A MARKET FOR CARBON ON TIMBER AND NON-TIMBER VALUES IN AN UNCERTAIN WORLD
Provedor de dados: 31
Autores: McCarney,   Geoffrey R.; Armstrong,   Glen W.; Adamowicz,   Wiktor L.
Despite considerable interest in the potential for forests to sequester carbon, the impact of carbon management on the provision of timber and non-timber resources has received relatively little attention in the literature. The introduction of value for stored carbon may result in modifications to traditional forest management objectives, generating trade-offs with other forest resources depending on the incentives provided by carbon markets. This paper investigates these issues by examining the impact of a particular form of carbon market on timber and non-timber values in a managed forest. An integrated modeling framework, developed for the incorporation of carbon management into operational timber management modeling tools, is also described. There is...

CONSUMER'S PERCEPTIONS OF ENVIRONMENTAL RISKS AND THE DEMAND FOR FOOD SAFETY
Provedor de dados: 31

Public concern regarding food safety has emerged as a major policy issue. Chemicals and biotechnological processes are perceived as risks of food safety despite their contribution to an efficient, low cost agriculture and food industry. Increases in uses of biotechnological processes for foods are expected to be a major potential source of productivity improvements for Alberta and Canadian agriculture in future years. However, the demand for food safety involves increasing awareness and concern by consumers of chemical inputs and biotechnological processes in the agriculture and food industries. Nonetheless, there is a lack of basic economic and agricultural economic theory and methodology to analyze these issues and a need for policy, socioeconomics and...

Provedor de dados: 31
Autores: Dosman,   Donna; Adamowicz,   Wiktor L.
The behavior of households has traditionally been explained by assuming that a single decision maker maximizes utility over all members of the household subject to a budget constraint. This unitary model of household behavior has been questioned and compared to models that assume that household decisions are made in a bargaining process. We examine household behavior in a bargaining framework by combining stated preference information from individual members of the household with revealed preference information on the household's actual choices.  The context of the decision is determining the location of family recreation vacation choice. The resulting model, based on a bargaining framework, provides information on the factors affecting bargaining power as...

Integrating Routine, Variety Seeking and Compensatory Choice in a Utility Maximizing Framework
Provedor de dados: 31
Autores: 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...

Choice Environment, Market Complexity and Consumer Behavior: A Theoretical and Empirical Approach for Incorporating Decision Complexity into Models of Consumer Choice
Provedor de dados: 31
Autores: Swait,   Joffre; Adamowicz,   Wiktor L.
Most empirical models of consumer choice assume that the decision-maker assesses all alternatives and information in a perfect information processing sense. The complexity of the choice environment, the ability of the individual to make complex decisions and the effect of choice context on the decision strategy, are generally not considered in statistical model development. One of the reasons for this omission is that theoretical literature on choice complexity and imperfect ability to choose has not been translated into empirical methods that permit such considerations in econometric analysis. In this paper we outline a theoretical model that considers task complexity, effort applied by the consumer, ability to choose, and choice. We then construct a...

Modeling Congestion as a Form of Interdependence in Random Utility Models
Provedor de dados: 31
Autores: 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.

This research explores the factors that influence the commitment of members to their cooperative organization. Previous empirical and theoretical research is reviewed. The cooperative members' decisions regarding patronage are then described in terms of a random utility model. Logit analysis, with data from member surveys of a large grain marketing cooperative. indicates that the factors that influence member patronage are: the ability to share in profits through dividends. The ability to purchase chemicals and fertilizers at the grain elevator, and the percentage of the total farm income obtained from grain operations. There is some evidence that farmers' patronage is positively associated with competitive grain pricing and negatively associated with the...

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...

These effects are compared with those of conventional agriculture and mixed agriculture (where alternative agriculture and conventional agriculture are practised on the same farm). The chosen research projects and areas in Chiang Mai province, Thailand were the government alternative agriculture project at Village Three in Pong Yang, and the nongovernmental organisations alternative agriculture project at San Pay Yang and the neighbouring San Lueng. The government and non-governmental organisations involved in the extension and marketing of alternative agriculture are outlined and...

The Effects of Trade Liberalization of the Environment: An Empirical Study
Provedor de dados: 31
Autores: McCarney,   Geoffrey R.; Adamowicz,   Wiktor L.
We seek to contribute to the emerging economic theory on trade, the environment and development. Using panel data across countries, econometric models are estimated to predict the effects of openness on organic water pollutant (BOD) and carbon dioxide (CO2) emissions. Results indicate that freer trade significantly increases emissions of both pollutants, thus reducing environmental quality. Moreover, the panel nature of the data allows heterogeneity across countries to be controlled, so that comparisons can be made of how different national characteristics influence the environmental impact of freer trade. By testing the effects of democratic versus autocratic governance, it is found that while greater democracy can induce significant reductions in BOD...

Bayesian Analysis of Consumer Choices with Taste, Context, Reference Point and Individual Scale Effects
Provedor de dados: 31
Autores: Hu,   Wuyang; Adamowicz,   Wiktor L.; Veeman,   Michele M.
This paper adopts an approach based on the concepts of random utility maximization and builds on the general theoretical framework of Lancaster and on the conceptual and econometric innovations of McFadden.  Recent research in this area explores models that account for context effects, as well as methods for characterizing heterogeneity, response variability and decision strategy selection by consumers.  This makes it possible to construct much richer empirical models of individual consumer behavior.  A Bayesian approach provides a useful way to estimate and interpret models that are difficult to accomplish by conventional maximization/minimization algorithms.  The application reported in the paper involves analysis of reference dependence and product...

A SEQUENTIAL CHOICE MODEL OF RECREATION BEHAVIOR
Provedor de dados: 31
Autores: Adamowicz,   Wiktor L.; Jennings,   Sarah; Coyne,   Alison.
The travel cost model is the standard model used in the recreation demand literature. This model assumes that the decision on the number of trips to a particular site in a given period (a season, for example) is determined at the beginning of the period. For certain types of recreation activity, this decision may be more appropriately modeled as a sequential process, in which the decision of whether or not to take each additional trip is made after previous trips have occurred.  This decision is dependent on the realization of random variables on previous trips as well as travel costs.  A model is developed in which the choice of a discrete number of sequentially chosen trips to a given site is specified as function of site-specific variables and variables...

DECOMPOSING UNOBSERVED CHOICE VARIABILITY IN THE PRESENCE OF CONSUMERS' TASTE HETEROGENEITY
Provedor de dados: 31
Autores: Hu,   Wuyang; Adamowicz,   Wiktor L.; Veeman,   Michele M.
Heterogeneous tastes across consumers can be captured by random coefficients in a mixed logit (ML) model.  However, other types of factors that may not directly affect taste could cause choices to vary, such as choice context, choice task complexity, and demographic characters. This paper jointly considers taste heterogeneity around reference-dependent attributes and other choice variability through inclusion of a scale function, based on data from a stated preference experiment for bread.  Results demonstrate that modeling other sources of choice variability in addition to taste heterogeneity increases the model fit, although the improvement is not dramatic.

An Experimental Investigation of the Impact of Fat Taxes: Prices Effects, Food Stigma, and Information Effects on Economics Instruments to Improve Dietary Health
Provedor de dados: 31
Autores: 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,...

MEASURING FOREST RESOURCE VALUES: AN ASSESSMENT OF CHOICE EXPERIMENTS AND PREFERENCE CONSTRUCTION METHODS AS PUBLIC INVOLVEMENT TOOLS
Provedor de dados: 31
Autores: Shapansky,   Bradford; Adamowicz,   Wiktor L.; Boxall,   Peter C.
Human values arising from forests include market and non-market values.  Timber values and values of non-timber forest products traded in markets (berries, wild rice, etc.) are considered market values.  Among non-market values are recreation values and values associated with wildlife harvesting by Aboriginal People. These are considered non-market because participation in these activities does not require the purchase of market based permits; prices do not function as rationing devices in these activities. In addition to non-market values arising from activities, individuals may also have values associated with forest conditions (biodiversity, etc.).  These are referred to as passive use values since the value is not associated with any specific use of...

Choice Task Complexity and Decision Strategy Selection
Provedor de dados: 31
Autores: Swait,   Joffre; Adamowicz,   Wiktor L.
The psychology, the marketing consumer behavior and, to a much smaller extent, the economics literature have long reported evidence that decision makers utilize different decision strategies depending upon many factors (person-specific, task-specific, etc.). Such observations have generally failed to affect the specification of choice models in commercial practice and academic research, both of which still tend to assume an utility maximizing, full information, indefatigable decision maker. This is true whether the models deal with Stated Preference (SP - from hypothetical elicitations) or Revealed Preference (RP - from actual market decisions) choice data. This paper, which deals only with SP data, addresses the following issues: (1) does task complexity...

Non-market Valuation Biases Due to Aboriginal Cultural Characteristics in Northern Saskatchewan: The Values Structures Component
Provedor de dados: 31
Autores: 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.

What's it worth? An examination of historical trends and future directions in environmental valuation
Provedor de dados: 31
Autores: Adamowicz,   Wiktor L.
The present paper reviews activity in environmental valuation by examining trends in publication rates over the past three decades. It also provides an overview of the demand for environmental valuation by academic markets and by policy markets. The results of this historical analysis suggest that there is not as much use of environmental valuation in policy analysis as could be expected given the academic efforts on this topic. The paper also provides an overview of the future directions that environmental valuation research is likely to take given current research efforts.

ANALYSIS OF "DON'T KNOW" RESPONSE TO REFERENDUM CONTINGENT VALUATION QUESTIONS
Provedor de dados: 31
Autores: 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.

FINANCIAL AND HEALTH COSTS OF PESTICIDE USE IN GROWING CONVENTIONAL AND GENETICALLY MODIFIED POTATOES IN PRINCE EDWARD ISLAND
Provedor de dados: 31
Autores: Adamowicz,   Wiktor L.; Veeman,   Michele M.; White,   Elspeth.
The majority of potato farming in Canada occurs in tightly clustered geographic locations and requires substantial chemical inputs.  The possibility of pesticide drift, pesticide residues on food and the effect of pesticides on the environment, leads to interest in quantifying the different effects that pesticides may have on human health and the environment.  This study focuses on the potential use of genetically modified potatoes, the associated issue of pesticide residues in the air, and the potential impact of this on the health of farmers, their families, and others in the context of Prince Edward Island.  Reductions in costs of potato farming and reduced health costs that may be associated with lower pesticide applications in growing genetically...

Tradeoffs Between Forestry Resource and Conservation Values Under Alternate Forest Policy Regimes: A Spatial Analysis of the Western Canadian Boreal Plains
Provedor de dados: 31
Autores: Hauer,   Grant; Cumming,   Steve; Schmiegelow,   Fiona; Adamowicz,   Wiktor L.; Weber,   Marian; Jagodzinski,   Robert.
An important element of resource management and conservation is an understanding of the tradeoffs between marketed products such as timber and measures of environmental quality such as biodiversity. In this paper, we develop an integrated economic – ecological spatial optimization model. The integrated model incorporates dynamic forest sector harvesting, oil and gas sector development, coarse filter or habitat based old-forest indicators, and a set of empirical forest bird models that predict bird abundance. Using our integrated model, economic tradeoff curves, or production possibility frontiers, are developed that illustrate the cost of achieving coarse filter targets by a set time (50 years) within a 100 year time horizon. We explore the production...

Conserving Water in Irrigated Agriculture: The Economics and Valuation of Water Rights

Autores: Veeman,   Terrence S.; Veeman,   Michele M.; Adamowicz,   Wiktor L.; Royer,   S.; Viney,   Bruce; Freeman,   Ruth; Baggs,   J.
The effective management of water resources in Alberta is crucial to sustainable agriculture, industrial development, and environmental management. The historical water allocation mechanism, administrative apportionment, has been viewed in recent years as ineffective and cumbersome. Accordingly, the revision of the Water Act in 1996, included an attempt to improve the efficiency of water allocation. By making the transfer of water rights possible, the revised Act provides many new options for water use and flexibility. The implications of transferable water rights in Alberta water policy must be carefully considered in order to determine the viability and suitability of such a system in the provincial context. This project examines some of the economic...

An Economic Evaluation of Woodland Caribou Conservation Programs in Northwestern Saskatchewan
Provedor de dados: 31
Autores: 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...

Provedor de dados: 31
Autores: 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.

NONPARAMETRIC ANALYSIS OF  ATTITUDES TOWARD RISKY CROPS: A PLANT MOLECULAR FARMING CASE STUDY
Provedor de dados: 31
Autores: Veeman,   Michele M.; Volinskiy,   Dmitriy; Adamowicz,   Wiktor L.
Research on plant molecular farming (PMF) is supported by public and private sectors in Canada. This may lead to benefits of new or cheaper medicines, industrial products and foods, but also be the source of appreciable risks to food safety from contamination by PMF materials, as well as potential environmental risks and costs. This study uses data from a 2005 nation-wide Canadian survey to gain insights into citizens’ perceptions of PMF benefits and risks. A series of nonparametric tests are conducted on ordinal survey data on risk and benefit assessments of respondents.  PMF is not seen as a major threat to food safety or the environment, but as a moderate indirect risk. The use of PMF to produce better and cheaper medical drugs appears to have the best...

AN ECONOMETRIC ANALYSIS OF DONATIONS FOR ENVIRONMENTAL CONSERVATION IN CANADA
Provedor de dados: 31
Autores: Yen,   Steven T.; Boxall,   Peter C.; Adamowicz,   Wiktor L.
As provincial governments in Canada trim budgets, fewer funds are available for environmental conservation programs. Many jurisdictions are letting private interests and/or users of the resource base help fund conservation projects. Thus funding for conservation is becoming more dependent on donations to environmental causes either through direct giving of funds or through memberships in organizations. This study explores some determinants of private contributions to environmental conservation activities through an econometric analysis of donations and memberships relating to wildlife habitat protection and enhancement. We use data from a 1991 survey conducted in the three prairie provinces that provides information on donation behavior, income,...
