Dietetics and Human Nutrition Faculty Publications

Prior work suggests that actual, but not estimated, energy density drives the reinforcing value of food and that energy from fat and carbohydrate can interact to potentiate reward. Here we sought to replicate these findings in an American sample and to determine if the effects are influenced by body mass index (BMI). Thirty participants with healthy weight (HW; BMI 21.92 ± 1.77; M ± SD) and 30 participants with overweight/obesity (OW/OB; BMI 29.42 ± 4.44) rated pictures of common American snacks in 120-kcal portions for liking, familiarity, frequency of consumption, expected satiety, healthiness, energy content, energy density, and price. Participants …

Travellers’ Willingness To Pay And Perceived Value Of Time In Ride-Sharing: An Experiment On China, Jamie M. Chen, Jesper De Groote, James F. Petrick, Tracy Lu, Peter Nijkamp

Retailing and Tourism Management Faculty Publications

Rapid development of the ride-sharing economy has led to a rising need to better understand travellers’ decision making regarding their travel time and cost. The present study conducted a travel choice experiment using smartphone applications, based on data collected from 532 respondents and 2128 stated-preference surveys in China. Based on prospect theory, the experiment utilized a coupon reward policy to analyze how much ride-sharing platforms might influence travellers’ choices in both work and leisure contexts. The results of an ordered logit model revealed that older residents were likely to pay more to reduce waiting time. It was further found that …

Reducing Survey Hypothetical Bias Through Revealed Behavior Priming: A Case Of Student Preference For Beef Served By University Dining, Gaby De Nascimento Mandlhate

Theses and Dissertations--Agricultural Economics

Economists are still searching for methods to reduce/eliminate Hypothetical Bias (HB). Different methods have been previously applied some with success and others without. In this study, we aimed to further test the cognitive dissonance approach (CD) through a learning design method to estimate the WTP for five beef attributes: Non-quality, Kentucky Proud, Appalachian, Grass Fed and a mix of 25% Non-quality and 75% Kentucky Proud, using a one and one half bounded model. To test the CD, 881 participants from the University of Kentucky, were randomly assigned to a real/hypothetical market for a battery recycling project at first and afterwards …

Point-Of-Sale Specific Willingness To Pay For Quality-Differentiated Beef, Kar Ho Lim, Michael Vassalos, Michael R. Reed

Agricultural Economics Faculty Publications

Despite the growing interest of producers and consumers toward grass-fed, local, and organic beef, the supply chain for these products to reach consumers is not always clear-cut. Among the available options are direct-to-consumers and the conventional food supply chain. Although consumers may pay a premium for beef differentiated by quality attributes, the willingness to pay (WTP) difference across point-of-sales is unclear. In this study, we contrast the WTPs for conventional, grass-fed, local, and organic beef by brick-and-mortar supermarkets (B&Ms), farmers’ markets, and via online stores. We conduct a choice experiment with a nationwide online sample of American consumers. The findings …

Agricultural Economics Faculty Publications

Sustainable tourism management plans rely on relevant and consistent information about factors that can influence the decision to visit a protected area. This paper uses the choice experiment method to investigate tourists’ preferences with regard to recreational trip characteristics in national and natural parks in Romania. An on-site survey questionnaire was administered to visitors. The multinomial logit model was employed to investigate the preference orderings of the identified groups of recreational users. Overall, results indicate that tourists gain benefits after visiting the parks. Main preference differences were found for information sources and location of campsites. Visitors who stated that the …

Selection Of Breeding Stock By U.S. Meat Goat Producers, Narayan Nyaupane, Jeffrey Gillespie, Kenneth Mcmillin, Robert Harrison, Isaac Stienei

Community & Leadership Development Faculty Publications

Using nationwide survey data, we investigate U.S. meat goat producer preferences and willingness to pay for meat goat breeding stock attributes. Discrete choice experiments were employed, and mixed logit and latent class models were used for analysis. Results showed that producers preferred animals that were highly masculine/feminine, had good structure and soundness, and were of the Boer breed, whereas they preferred fewer animals that were older, of Kiko and Spanish breeds, and priced higher. Significant preference heterogeneity was found among the respondents. Larger-scale producers had greater preference for high masculinity/femininity, good structure and soundness, and Boer bucks.

Values For Recreational Beach Quality In Oahu, Hawaii, Jerrod M. Penn, Wuyang Hu, Linda Cox, Lara Kozloff

Agricultural Economics Faculty Publications

Pristine coastal environments are the key to Hawaii’s worldwide fame and attraction to tourists, yet their economic value remains understudied. This article examines preferences for characteristics associated with beach recreation in Oahu, Hawaii, among residents and tourists. Consideration is given to sand quality, water quality, congestion levels, and swimming safety conditions in the context of a choice experiment. The choice experiment conveys attribute levels almost entirely through pictures, and results suggest that this novel portrayal is well understood by respondents. Excessive congestion and water quality are regarded as the most important beach attributes, specifically the avoidance of poor water quality …

Economic Considerations Of Aggressively Treating The Influenza Virus In Equines, Charlotte R. Hansen

Theses and Dissertations--Agricultural Economics

The equine influenza virus is a significant cause of respiratory disease in horses. Even though horses generally recover from this virus, sometimes horses with equine influenza develop secondary bacterial infections which can cause severe pneumonia, thereby increasing recovery times. Owners and managers are faced with the decision of whether to delay preventative treatment in hopes of the horse avoids contracting a secondary bacterial infection (“wait and see”) or aggressively treat the horse with an antibiotic in hopes of avoiding a serious infection (“treat now”). From a decision making standpoint, the economic considerations include explicit treatment costs as well as nonmonetary …

A Conjoint Analysis Study Of Preferences And Purchasing Behavior Of Potential Adopters Of The Bureau Of Land Management Wild Horses, Omotoyosi O. Adekunle

Theses and Dissertations--Agricultural Economics

This study uses conjoint analysis to examine the preferences of buyers for Bureau of Land Management (BLM) wild horses based on physical attributes of wild horses and individual characteristics of the buyers. Generalized ordered logit models and multinomial logit models are used to study the impact of the buyers’ demographic characteristics such as age, gender, knowledge about wild horse care, and number of wild horses previously adopted on physical attributes of the horses such as color, age, height, training status, temperament, conformation, and unique markings. Using a choice experiment, taken together, these attributes determine buyer’s preferences for a wild horse. …

Farmers’ Willingness To Pay For Breeding Sow Insurance: Evidence From China’S Hubei Province, Wei Wan

Theses and Dissertations--Agricultural Economics

China is the world’s largest pork producer and consumer, and Hubei Province is one of the top pork production provinces in China. Since problems and risks have led to large-scale reduction of pork production and farmers’ income, Chinese government offers various policy measures to help farmers. Breeding sow insurance is considered as one of the most effective measures started in 2007. To better understand farmer’s need for breeding sow insurance and make proper policy insights, our research is the first empirical study in Hubei Province and one of the pioneer studies investigate farmer’s willingness to pay(WTP) for breeding sow insurance …

Thoroughbred Farm Managers' Willingness-To-Pay For Alternative Deworming Regimens In Horses, Marion Angélique Robert

Theses and Dissertations--Agricultural Economics

Parasite control is important to horse health and horse owners should feel highly concerned about the proper treatment of parasites. In the past 30 years, veterinary science has made important advances in treating parasites and provided new products and strategies to optimize treatment and prevention. However, horse owners and managers have been slow to adopt these new recommendations.

This study investigates why the transition has not occurred as expected. It examines issues related to the decision-making process of horse owners and managers as they relate to deworming strategies. In addition, it investigates current deworming approaches as well as attitudes towards …

Valuation Of Recreational Beach Quality And Water Quality Management Strategies In Oahu, Jerrod M. Penn

Theses and Dissertations--Agricultural Economics

Hawaii’s pristine ocean and tropical environment is a keystone of Hawaii tourism and the state economy. Water pollution from stormwater and development threatens the beach quality to both residents and tourists. In order to understand the lost nonmarket value, we assess changes in quality of beach characteristics including water and sand quality, swimming safety conditions, and congestion using a Discrete Choice Experiment of recreational beach users. Further, we study willingness to pay (WTP) for water management strategies in Hawaii using another discrete choice experiment, including structural and nonstructural Best Management Practices, testing, monitoring, and educational efforts.
