A VALUATION OF PUBLIC DEMAND FOR THE PARTICIPATION OF NONGOVERNMENTAL AGENCIES IN MONITORING AND ENFORCING FOOD SAFETY REGULATIONS AgEcon
He, Senhui; Fletcher, Stanley M.; Rimal, Arbindra.
Lack of consumer trust in governmental food safety regulators hinders the promotion of consumer confidence in the safety of their food supply. One possible way to boost consumer trust is to allow nongovernmental agencies to participate in monitoring and enforcing food safety regulations. This study identifies factors affecting consumer desire for the participation of nongovernmental agencies. The information obtained from this study can be used in further valuation of the feasibility of the participation of nongovernmental agencies.

THE EFFECTS OF IRRATIONAL RESPONSES IN CONTINGENT VALUATION SURVEY AND THE APPROPRIATE TREATMENT AgEcon
He, Senhui; Fletcher, Stanley M.; Rimal, Arbindra.
This paper investigates the effects of irrational responses on stated willingness-to-pay (WTP) in a contingent valuation study. A significant portion of the respondents stated that they were willing to pay a higher price for irradiated beef which they would avoid consuming due to their concerns about the side effects of irradiation. Such responses may not reflect true WTP and may cause bias in WTP estimate. Excluding these responses from estimation may result in sample selection bias. Whereas setting the bid values presented to these responses close to zero both helped to improve the estimation model and to reduce the potential bias in WTP estimate.

CONSUMPTION OF REDUCED-FAT PEANUT BUTTER IN ADDITION TO THE CONSUMPTION OF REGULAR PEANUT BUTTER AgEcon
He, Senhui; Fletcher, Stanley M.; Rimal, Arbindra.
A set of factors has been identified to affect consumption of reduced-fat peanut butter in addition to regular peanut butter. We found that consumption of reduced-fat peanut butter, which is an imperfect substitute for regular peanut butter, may expand total demand for peanut butter. Interestingly, for those who usually buy the same brand of peanut butter, their consumption of reduced-fat peanut butter is more likely in addition to consumption of regular peanut butter, implying promotion of a specific brand of reduced-fat peanut butter tend to increase total demand for the same brand of peanut butter.

British Columbia Consumers' Preferences for Italian Wines: Reputation and Vintage Effects on Wine Quality and Prices AgEcon
Florkowski, Wojciech J.; Carew, Richard; He, Senhui.
Italian wines have been enjoyed by Canadian consumers for decades and the consumption is not limited to the ethnic Italian population. The study examines effects of wine characteristics and the brand associated with the designation of geographic origin estimating five hedonic price equations for Barbaresco; Barbera; Veneto (Valpolicella, Amarone and Reecioto); Soave; and, Chianti and uses weekly sales data from British Columbia retail outlets. Results indicate that, in general, a premium was paid for higher alcohol content, but the effects of individual brands within each area of origin varied and the range of price premia and discounts was from 14% to -12% suggesting that small price changes with regard to the baseline wine price could affect purchase.

Irrational Responses in Contingent Valuation and Their Potential Impacts on Mean Stated Willingness-to-pay AgEcon
He, Senhui; Florkowski, Wojciech J.; Jordan, Jeffrey L..
This paper addresses the issue of rationality of responses in contingent valuation. We found a significant portion of respondents stated a positive willingness-to-pay for a project they perceived to be worthless. The irrational responses had a significant impact on the mean stated willingness-to-pay and the effect can not be removed by simply excluding the those observations from estimation. The dichotomous-choice elicitation format helps to mitigate the effect of the irrational responses, but can not completely solve the problem.

CONSUMER CHARACTERISTICS INFLUENCING THE CONSUMPTION OF NUT-CONTAINING PRODUCTS AgEcon
He, Senhui; Florkowski, Wojciech J.; Elnagheeb, Abdelmoneim H..
The study estimates the influence of consumer characteristics on the consumption of four nut-containing products, that is, the consumption of nuts as a snack, in salads, covered in chocolate, and in ice cream. Gender, age and education are among the characteristics that frequently influence nut consumption. Female, older, and non-white respondents consumed nuts as a snack more often than male, younger, and white consumers did. Chocolate-covered nut consumption was associated with higher income and rural consumers while nut-flavored ice cream was consumed more frequently by older rather than younger respondents and respondents from larger households.

FACTORS AFFECTING CONSUMER NEGATIVE PERCEPTIONS ABOUT BEEF IRRADIATION AgEcon
He, Senhui; Fletcher, Stanley M.; Rimal, Arbindra.
This study has identified several important factors affecting consumer negative perceptions about beef irradiation. The effects of these factors boil down to two main points: lack of trust in the adequacy and enforcement effectiveness of food safety regulations and consumer ignorance about the irradiation process. This implies dissemination of information about food irradiation and enhancement of consumer trust in the mechanism of food safety regulation can be effective instruments to increase consumer acceptance of beef irradiation.

THE EFFECTS OF RESEARCH ON WHEAT YIELDS AND YIELD VARIANCES AgEcon
He, Senhui; White, Fred C.; Fletcher, Stanley M..
This paper investigates the impacts of research investment on wheat production. A two-way error component random effect model was estimated using panel data to examine the effects of research investment on mean yield and yield variance. Results show that, for the time period between 1974 and 1995, research investment enhanced yield stability but had no significant impact on mean yield. Key words: yield, yield variance, research investment.

RESEARCH SPILLOVERS AND RETURNS TO WHEAT RESEARCH INVESTMENT AgEcon
He, Senhui; White, Fred C.; Fletcher, Stanley M..
This study evaluates the rates of return to US wheat research investment, focusing on research spillovers. Results show that research spillovers exist among various classes of wheat. Due to the spillover effects, social rates of return to research investment are substantially higher than the corresponding private rates of return.

INCOME REMINDER AND THE DIVERGENCE BETWEEN WILLINGNESS-TO-PAY ESTIMATES ASSOCIATED WITH DICHOTOMOUS CHOICE AND OPEN-ENDED ELICITATION FORMATS AgEcon
He, Senhui; Jordan, Jeffrey L.; Florkowski, Wojciech J..
This study investigates whether an income reminder can reduce the divergence between the willingness-to-pay (WTP) estimates associated with the open-ended (OE) and dichotomous choice (DC) elicitation formats. Results show that without an income reminder, WTP estimate associated with DC elicitation format is about 1.66 times as large as that associated with OE elicitation format. With an income reminder, the WTP estimate associated with DC format decreased while the WTP estimate associated with OE format increased, and the divergence between the WTP estimates was almost eliminated.
Tipo: Conference Paper or Presentation Palavras-chave: Dichotomous choice; Open-ended; Income reminder; Water quality improvement; Willingness-to-pay; Research Methods/ Statistical Methods.
