En Guadeloupe, depuis 2008, les autorités locales ont fortement encouragé l’organisation des filières de traitement des déchets. En ce qui concerne les déchets organiques, une voie privilégiée de valorisation est le recyclage en compost. Dans cette thèse nous étudions les conditions d’émergence d’une filière de recyclage des déchets organiques du territoire à travers l'analyse des conditions d'adoption de la pratique d’utilisation de composts par les agriculteurs. Nous nous appuyons sur une approche originale combinant une analyse ex post des pratiques actuelles et des perceptions des agriculteurs et une analyse ex ante par Choice Experiment de leviers visant à favoriser l’adoption des composts. Nous testons donc des leviers d’ordre biotechniques concernant les propriétés des composts et les modalités de leur utilisation, et des leviers d’ordre économiques à travers des Mesures Agro-environnementales et Climatiques (MAEC), afin de proposer aux décideurs politiques des leviers d’actions pertinents. Nous constatons que le taux d’adoption est faible (18%) et dépend fortement de la filière agricole, des caractéristiques socio-économiques des agriculteurs et du manque d'organisation de la filière de recyclage des déchets (p.ex. information, transport, épandage, subventions). Nous montrons que les agriculteurs sont sensibles, sur le plan biotechnique, à une amélioration de la valeur fertilisante des composts ainsi qu’à un accompagnement logistique pour son transport et son épandage et, sur le plan économique, à la mise en place d’un dispositif d’accompagnement administratif et à une incitation collective sous la forme d’un bonus monétaire conditionnel versé individuellement aux agriculteurs. Dans l'ensemble, les résultats de ce travail montrent que les agriculteurs ne sont pas réfractaires à une utilisation conséquente et régulière du compost, à condition que les verrous organisationnels que nous avons identifiés soient levés, et que la valeur agronomique des composts répond aux attentes des filières agricoles. Des plans de développement peuvent maintenant être définis et mis en œuvre à l’échelle du territoire pour développer l’utilisation massive de composts issus du recyclage des déchets organiques du territoire. / Due to the limited availability of landfill sites, local authorities have strongly encouraged since 2008 the structuration of waste treatment channels. As concerns the organic wastes, a special attention has been paid for recycling them through composting. In this study, we focused on the conditions of development of a sector for recycling organic wastes in Guadeloupe through the assessment of the conditions affecting compost adoption by farmers. In order to identify and evaluate the determinants of farmers 'choices, we applied an original approach combining an ex-post analysis of current practices and farmers' perceptions, and an ex-ante analysis using the Choice Experiment method of levers for facilitating the adoption of compost. We test biotechnical levers concerning compost properties and the facilitation of practices with technical support, and economic levers mainly focused on the implementation of new AgroEnvironmental Schemes (AES) to promote economically the composts. We observed that the adoption rate is relatively low (18% of farmers) and highly dependent on the agricultural sector (i.e. banana, sugarcane, vegetables and food crops), the socio-economic characteristics of the farmers and the lack of organization of the waste recycling chain (e.g., information, transport, spreading, subsidies). We demonstrated that farmers are very sensitive to the improvement of compost quality by increasing its fertilizer value, as well as to the logistical, economic and administrative support for its transport and spreading. They are also willing to participate in a collective incentive in the form of a conditional monetary bonus paid individually to farmers. The results of this study indicated that farmers are not reluctant to a regular use of compost provided that organizational barriers identified are removed, and that the agronomic value of the composts meets the expectations of farmers. Regional plans can now be defined and implemented to develop the massive use of compost from the recycling of organic waste in Guadeloupe.

Master of Science / Department of Agricultural Economics / Hikaru H. Peterson / This study investigates consumers’ preferences for organic baby meals. The growth of the U.S organic industry has been notable during the last two decades. The U.S. organic farmers do not produce enough quantity to meet the increasing U.S demand for organic food, and increasingly more organic foods are manufactured from organic ingredients produced outside the U.S. Tensions have emerged in the organic sectors as large-scale companies have seized opportunities to sell products differentiated with the organic label. The study aimed to estimate U.S. consumers’ willingness to pay (WTP) for selected attributes (type of brand, production attributes, and origin of ingredients) of baby meal products using a choice-based conjoint analysis. The organic offerings represent a nontrivial share of this market. In recent years, offerings under store brands have also been increasing. The study identified that consumers preferred a major national brand with a large market share such as Gerber (80%) to the other types of brands including store brands. In terms of product characteristics, pesticide free and non-GMO products were seen as consumers’ top priorities. Consumers would not buy products that did not exhibit these two characteristics. Minimally processed products seemed not to matter for the majority of consumers, and these products (sold frozen) were expected to be a niche market. Besides, a product made with U.S ingredients (organically or non-organically grown) was associated with a higher utility. Firms can run a cost-benefit analysis to see if sourcing U.S. ingredients could increase profit. Running experimental auctions are recommended to firms that want to elicit WTP for U.S grown ingredients and implement an efficient marketing strategy. This study is a preliminary analysis that highlighted consumers’ preferences in the baby food market, and future analysis would complement the findings.

Master of Science / Department of Agricultural Economics / Hikaru H. Peterson / Alexander E. Saak / Notable changes are occurring in the U.S. organic food sector. First, the U.S. organic food system is increasingly relying on imports, because the expansion in the organic production has failed to satisfactorily meet the rapidly growing demand for organic foods. Second, the “locally grown” concept has become appealing to consumers, with some evidence of consumers switching from certified organic foods to local, conventional foods. Third, organic food has penetrated the mass-market channel, and organic foods are no longer being sold exclusively in natural product stores. And fourth, the social and environmental awareness among consumers is increasing. Thus, consumers are also willing to pay a price premium to support small farmers. To understand how these changes are affecting the demand for organic foods, this study used survey data to assess U.S. consumers‟ preferences for fresh organic apples that are sourced from various places and from supply chain operations that vary in scale. The survey was administered via the Internet to a random sample of 285 households across the U.S through a research company. Choice experiment was selected as the valuation method. Results indicate that among the levels of the location attributes, the “locally grown” label was associated with the highest average WTP. The “regionally grown” was the second most preferred, “U.S. grown” the third, and “imported” the least. The “locally grown” label was valued higher than the “certified organic label”. Also, consumers were willing to pay a higher value for apples produced on a small farm compared to those from a large farm. However, they did not distinguish the type of retail outlets where apples were offered. The analysis incorporating the effects of consumer characteristics suggest that the perceived importance of public benefits impacted the values of origin attributes more than the private ones; the type of retail outlet attributes became significant among certain gender and age segments; and the value of small farm attribute increased with consumers‟ income. Finally, results from a theoretical model suggest that the variability in the WTP obtained among the origin attributes could be explained by the reputation of product quality depending on their origin.

Natural disasters are increasing in frequency and intensity and have devastating impacts on individuals, both humanitarian and economic, particularly in developing countries. Microinsurance is seen as one promising instrument of disaster risk management, however the level of demand for respective projects remains low. Using behavioural games and a discrete choice experiment, this paper analyses the demand for hypothetical microinsurance products in rural Cambodia and contributes significant household level evidence to the current research. A general preference for microinsurance can be found, with demand significantly affected by price, provider, requirements for prevention and combinations with credit. Furthermore, financial literacy, risk aversion, levels of trust and previous disaster experience impact the individual demand for flood insurance in rural Cambodia.

As information regarding origin, production method, and environmental certifications characterize a progressing seafood market, scare analysis has been made to understand market responses. This study focuses on consumer preference for wild-caught and farm-raised shrimp with several attributes. These include the Homegrown By Heroes label and Best Aquaculture Practices certification, as well as other existing attributes including the Marine Stewardship Council and each state’s local label. Also considered are hypothetical labels including Community Supported Fishery (CSF) and National Oceanic & Atmospheric Administration (NOAA). This study surveys consumers in Kentucky and South Carolina while utilizing a choice experiment to elicit willingness-to-pay measures for these various product attributes. Both wild-caught and farm-raised shrimp are considered since these species have significant market potential. Like previous studies, a strong preference for fresh as well as local shrimp was found. Furthermore, preference for Homegrown By Heroes was found to be highly valued by consumers, as well as the NOAA label signifying a federally operated ecolabel. Consumers were also found to value BAP and MSC certifications, two third-party agencies currently existent in the seafood market. Marketing and policy recommendations are given based on consumer willingness to pay estimates for these various seafood attributes in both states.

As the world's most populous country, with more than 16 million births every year, China has emerged as a large importer of baby formula. China's relaxation of the one-child policy, which was announced in 2015, is expected to increase the number of births significantly and therefore increase the demand for Chinese and imported baby formula. While information on parent preferences for baby formula is very important for understanding and predicting China's import demand for baby formula and other products used to produce baby formula, like milk powder, there are very limited empirical studies on Chinese parent preferences for baby formula in the literature due to data limitation and other reasons. This research collects primary data from China through a parent survey, uses the data to analyze parent preferences and willingness to pay (WTP) for selected baby formula attributes, and derives implications for U.S. dairy product exports. Specifically, with detailed data from a total of 433 respondents, this study first examines parent purchase behavior of baby formula through descriptive analysis, then assesses parent preferences and WTP for selected baby formula attributes through the estimation of a random utility model, and finally derives implications for U.S. exports of milk powder, whey, and other dairy products. The descriptive analysis suggests that education level and income play an important role in parent purchase behavior of baby formula. The estimation results of the random utility model differed according to whether the survey was administered online or as a hardcopy. The results from the online survey indicate that imported, organic, and more reputable brands of baby formula are more attractive to respondents than domestic, non-organic, and less reputable brands. While respondents who completed the hardcopy survey also indicated a preference for organic baby formula from a reputable brand, they preferred domestic baby formula to imported formula. Further analysis of the WTP from the online survey for baby formula showed that parents have a strong preference and are willing to pay significantly more for baby formulas produced in Australia and the U.S. as compared to that produced in China. They are willing to pay more for organic baby formula and baby formula with an excellent reputation. The WTP results from the hardcopy survey indicate that parents are willing to pay more for domestic baby formula. They are also willing to pay more for organic baby formula and baby formula with an excellent reputation. China's emerging demand for imported baby formula, milk powder, and whey may bring more opportunities for the U.S. dairy industry, but U.S. dairy products are also facing increasing competition from similar products from other nations in the Chinese market. More studies are needed to identify the comparative advantages of U.S. baby formula and other dairy products in the Chinese market and to develop effective trade policies for enhancing U.S. exports to China.

Master of Science / Department of Agricultural Economics / Glynn Tonsor / Recent predictions estimate that the global population will reach more than 9 billion by the year 2050 (Kochhar, 2014). Coupled with this challenge, environmental issues and climate change influence agricultural production over the globe (Jacobsen et al., 2013). Changes in the food chain have been in response to consumers becoming interested in how their food is produced as it relates to food safety. Some of these changes have come in the form of labeling of production methods and the increasing volume of organic products in the marketplace. In the livestock sector, production methods include administration of antibiotics and hormones to prevent disease, increase gains and increase the health of animals (Allen et al., 2013; Thornton, 2010). A potential solution of decreasing the amount of antibiotics and hormones in the future is the use of ribonucleic acid interference (RNAi). RNA interference is a method of silencing a targeted gene and suppressing expression (Bradford et al., 2016). The focus of this research is to explore the determinants of acceptance and willingness to pay for beef products utilizing RNAi technology in the food system. Through the means of a national survey, consumers were asked their demographic, food purchasing habits, and food safety concerns to identify potential acceptors of the technology. Respondents received information treatments and external articles regarding RNAi technology as well as information about governmental labeling regulations of the beef steaks. Choice experiment questions, and a dichotomous choice sequence were utilized to determine willingness to pay estimates of beef steak attributes by consumers. Results showed that respondents likely require a discount for beef steaks produced with RNAi technology. In some instances, some consumers would be willing to pay a premium for beef steaks with RNAi in certain label settings. These results of this study could be used in the realm of animal science to help with the introduction of this technology in the food system. The survey results could assist with future promotion and framing of the technology to a wide variety of consumers.

Background: As rural hospitals in Kentucky face insolvency, stakeholders must assess the value of rural hospitals as well as alternatives such as rural clinics and private physician offices. Objective: To identify the value of attributes of healthcare facilities based on Kentucky’s rural residents’ willingness-to-pay (WTP). Methods: A survey instrument was created and distributed to ten counties in rural Kentucky. A conditional logit model was used to obtain baseline values and then a mixed logit model was used to address heterogeneity among consumers in estimating WTP. WTP values incorporated respondents’ demographic characteristics and their health status from self-reported frequency of use of medical services and distance from these services. Results: The results indicate that on average respondents were willing to pay $69.90 each year for the attribute of a facility that treats patients whether they have health insurance or not, compared to a facility that only accepts patients with private health insurance. Uninsured residents were willing to pay $81.15 for this attribute level. Conclusion: The study suggests that uninsured residents value this attribute level of a facility that grants them access to care. Stakeholders may justify such welfare benefit amounts in support of the establishment or maintenance of such a facility.
