In this dissertation research, we first study how legislations governing nutrients in food production have influenced consumer behaviors and firm choices. Taking margarine and spreads as the product category of choice, Chapter 1 analyzes how consumers and firms responded to the 2006 implementation of the NLEA trans fats labeling guidelines. Our results show that product offerings with "trans fat free" labels increased shortly after 2006, while consumer purchases of products with "trans fat free" labels also surged promptly after the labeling policy was implemented. However, in general, we find the short-term effects of trans fat labeling to be significantly larger than the long-term effects. In Chapter 2, we extend the previous research in estimating consumers' willingness to pay for trans fat using scanner data on purchases of microwavable popcorn from 2006 to 2014, after mandatory labeling was instituted. Product-level multinomial logit model results suggest that trans fat content on average increases consumer demand, with significant regional preference heterogeneity. Consumers in the Northeast have a higher preference for trans fat popcorn than in the other three regions. In addition, we find evidence to show that this positive preference for trans fat has become stronger since the 2006 mandatory labeling rule, implying that consumers value the taste of trans fat over trans fat health concerns. Chapter 3 explores the WIC infant formula rebate program, which awards a single-source contract to the firm that offers the lowest net bid price. We find different spillover patterns by comparing three types of formula: top WIC infant formula, non-WIC infant formula, and toddler formula. In particular, immediately after the contract change, there is a significant increase in market share for all three types of formula for the winning manufacturer due to greater shelf space, better product placement, and the advantages of carrying WIC labels. Our empirical results suggest that losing manufacturers still enjoy a spillover privilege in the toddler formula market from consumers' brand loyalty. Over time, the spillover effect increases the winner's share and decreases the losers' shares for all infant formula, which may reflect a combined impact of recommendations from physicians and WIC participants. Lastly, we observe that winning manufacturers increase the price of top WIC and all other infant formula and decrease the price of toddler formula over time. The spillover effect allows losing manufacturers to increase prices for all three types of formula at least 2 years after a contract change.

This dissertation presents three essays on disruptions along nutritional high-value food supply chains in emerging countries. It extends our understanding of threats to the attainment of food security in emerging countries. With a contribution to agricultural economics, the dissertation relies on value chain, market growth and price transmission theories and applies both panel data and time series econometric techniques to analyse the sources and magnitudes of the disruption of nutritional high-value food chains.The first part of the dissertation examines disruptions in unprocessed and minimally processed nutritional high-value food markets. Chapter 2 examines upstream and downstream disruptions along these food chains. Chapter 3 extends the analysis in Chapter 2 by assessing how disruptions change when nutritional high-value foods are highly processed. For each of the two chapters, disruptions are studied in terms of changes in upstream and downstream quantities and prices, with the disruption of quantity considered primary while that of prices is secondary.Using the São Paulo food market as a case study, Chapter 4 analyses the effect of diesel price shocks on different segments of the nutritional high-value food supply chain. A Vector Error Correction Model (VECM) that takes into account upstream and downstream cross-price effects is estimated to ascertain if diesel price shocks are higher downstream based on price transmission theory.The results of Chapters 2 and 3 show that climatological disasters are the most dominant source of disruption of nutritional high-value food supply chains and the direction of impact is negative for all foods under study. The magnitude of disruption, however, varies by food. From the VECM results in Chapter 4, we see that the price of diesel has a positive and significant effect on food prices, while the effects downstream are lower than those upstream. These results have significant implications for the design and implementation of food policies in emerging countries.As a general introduction, Chapter 1 justifies the need to study upstream and downstream differences in the magnitude of supply chain disruption, by situating the dissertation in the existing supply chain and food price transmission literature. Chapter 5 concludes the study and offers suggestions for future research.

The proportion of the world's population that directly interacts with agriculture and natural resources for their daily bread is declining amidst structural transformation (Timmer et al. 2009). Commensurately, the expectations and hopes placed on the remaining food and fiber producers in the world seems to ever increase, not only in terms of the provision of food and fiber, but increasingly in terms of environmental management and the conservation of intersecting natural resources (Blundo et al. 2018, Messerli et al. 2019, Wunder et al. 2020, Baylis et al. 2022). It is not a stretch to declare that there is a lot riding on the welfare of the food and fiber producers of the world (e.g., food security), and on the extent to which conditions that enhance the welfare of the farmer (gatherer) also enhance general welfare in matters beyond the direct provision of food and fiber (e.g., climate change, pollution control, and biodiversity conservation). To manage this state of affairs, the economics underpinning the production behavior of food and fiber producers and associated realized outcomes, are paramount to understand theoretically and to test empirically. In what follows, three applications are studied, each with a focus on a renewable natural resource of concern and an intersecting agricultural production sector where little to no empirical work has be done. The settings and questions are each broadly important and timely: * Do food price shocks cause deforestation, and if so how? * How do farmers decide whether to use managed pollination service markets, and are observed use patterns optimal? * Does the provision of index-based agricultural insurance lead to resource degradation, or improvement? Although on one level these topics are unrelated, the reality is that there are similar archetypal economic problems at the root of each of these questions, where the welfare of an agricultural agent, and the impacts from their production behavior, may or may not coincide with a social optimum. In chapter 2, evidence is presented that food price shocks, particularly for staples, can have significant impacts on deforestation (particularly through increases in price levels), that such shocks can drive smallholders to expand production broadly to address internal shocks to consumption and production, and that such land use change patterns can be casually miss-attributed to cash crop markets. In chapter 3, it is demonstrated that pollination dependent farmer's crop pollination behavior may be less static than has been presumed, that crop pollination behavior and production outcomes are influenced by adjacent land use and landscape heterogeneity, that there are diminishing returns to managed pollination use, and that reliance on pollination service markets is intimately related to the farmers production technology. In chapter 4, the roll-out of a successful index-based agricultural insurance product is studied at-scale, which theoretically might lead to resource degradation, or improvement (in this case for rangeland quality), and evidence is presented that resource degradation concerns may be over-blown, lending credence to the idea that addressing missing financial markets can enhance productivity and agent's welfare without degrading fundamental natural resource stocks.

This dissertation consists of three independent and mostly interrelated studies that focus on consumer behavior in the areas of food and healthcare. In my first paper, my coauthors and I analyze consumers' willingness to pay and preferences for reduced food waste and increased shelf life in relation to refrigerated ready-to-eat meals. We find evidence to suggest that consumers are willing to pay for reduced food waste, but willingness to pay for increased shelf life depends on the group being considered. The groups can be separated into health-conscious and on-the-go shoppers where only the on-the-go shopper is willing to pay a premium for a product with an increased shelf life. My second paper elicits consumers' willingness to pay for a clean label and a novel microwave technology. The results suggest that consumers are willing to pay for a clean label and the magnitude varies by group. There are also groups who are willing to pay a premium for the novel technology, but it is not homogeneous among groups. In my third paper, my coauthor and I present a theoretical model of health care consumption in emergency departments and in outpatient settings as functions of patients' time, market price of health care, and health insurance coverage. Applying our theory to data from the Behavioral Risk Factor Surveillance System (BRFSS), we examine the relationship between health care utilization and health insurance coverage. From the interaction between the price effect and the network effect we find that an insured individual in a rural area has a lower likelihood of a checkup within the last year compared to an insured individual in an urban area.

A significant amount of attention has been focused on both the prevalence of obesity in the United States and the corresponding interest in maintaining a healthy lifestyle. My research concentrates on one aspect of this trend: food access. One perceived component of healthy food is consumption of certified organic produce. However, consumers that purchase organic products may be doing so because of an assumed relationship with local or sustainable production. My first essay teases out these two effects by concentrating on Community Supported Agriculture (CSA) operations in order to measure a consumer's willingness to pay for certified organic produce that is already local. CSA farms differentiate themselves on a variety of characteristics, including certification status, and a hedonic model of CSA share prices is used to find the marginal valuation of each CSA attribute. I find that consumers are willing to pay for certified organic produce, even when food is already local, and that this premium does not hold for competing certification programs. I also adapt a firm entry framework from the industrial organization literature to the local food market and find that the majority of the study regions exhibit perfect competition in the CSA market.
