    This dissertation analyzes the market effects of the coexistence of genetically modified organism (GMO) and conventional production, labeling policies, and strategic firm interactions through vertical product differentiation. Although we focus on GMOs, the applied frameworks can be adopted and extended to other differentiated products where similar concepts apply.

    The main body of the dissertation consists of four chapters. In the first chapter, we estimate the perceived costs of legal requirements (‘coexistence measures’) for growing genetically modified (GM) Bt maize in Germany using a choice experiment. The costs of the evaluated ex-ante and ex-post coexistence measures range from zero to more than 300 euros per hectare per measure, and most of them are greater than the extra revenue the farmers in our survey expect from growing Bt maize or than the estimates in the literature. The cost estimates for temporal separation, which were the highest in our evaluation, imply that the exclusion of this measure in Germany is justified. The costliest measures that are currently applied in Germany are joint and strict liability for all damages. Our results further show that neighbors do not cause a problem and that opportunities for reducing costs through agreements with them exist. Finally, we find that farmers’ attitudes toward genetically modified crops affect the probability of adoption of Bt maize. Our results imply that strict liability will deter the cultivation of Bt maize in Germany unless liability issues can be addressed through other means, for example, through neighbor agreements.

    The coexistence costs have implications for the supply of products in which GMOs are excluded from the production process (i.e., non-GM labeling). This is the topic of the second chapter. In that chapter, we discuss and illustrate the complexity of non-GM food labeling in Germany. We show how a multi-stakeholder organization that sets a voluntary private production and certification standard can combine the opposing and agreeing interests of its members. This cohesion reduces the fears of retailers of NGO pressure in the case of mislabeling. Whereas non-GM labeling in Germany started as a niche for farmer-to-consumer direct marketing and small processors, it was further driven by anti-GMO organizations. Today, retail chains label some of their store brands and are now the drivers. We also discuss how informing consumers through non-GM labeling addresses imperfect information, but at the same time, can create new information imperfections if consumers are not well informed about the labeling system itself.

    Non-GM labeling, together with the EU-wide mandatory labeling of GMOs and their requirements on coexistence, have implications for the potential regulation of crops derived by new plant breeding techniques (NPBTs). In the third chapter, we analyze the market and welfare effects of regulating crops derived by NPBTs as genetically modified or conventional products. We consider the mandatory scheme for labeling GM products and a voluntary non-GM scheme for labeling livestock products derived from non-GM feed. We develop a partial equilibrium model that explicitly takes into account both the coexistence costs at the farm level and the segregation and identity preservation costs at the downstream level. By applying the model to EU rapeseed, we find that regulating NPBTs as GM (as compared to non-GM) in combination with mandatory and voluntary labeling increases prices and therefore makes producers better off. We also show that higher coexistence costs make the price increasing effect even stronger. Voluntary non-GM labeling applied to feed makes consumers in this sector overall worse off, but it benefits farmers and rapeseed oil consumers overall as long as segregation costs are low. Consumers of biodiesel and industrial products, such as lubricants produced from GM rapeseed, benefit from high segregation costs. We show that the effects of farm-level coexistence costs largely differ from the effects of downstream market segregation costs.

    In the last of the four chapters, we consider the effects of market power and analyze the decision of investing in quality updating when high-quality product demand is growing. We model a decision of a duopoly that initially offers a product perceived as lower quality (e.g., GM product) to invest in an emerging high-quality (e.g., labeled non-GM) product. We investigate whether the smaller or the larger firm invests first. Either preemption or a war of attrition can result, depending on demand and cost factors. For each case, we derive the unique Nash equilibrium. We show that a firm’s timing to invest in high-quality production (e.g., implement a voluntary production standard) depends on several factors, such as the difference in firm size between competing firms and the level of vertical differentiation, growth and discount rate, demand parameters, and per-unit production costs. We show that institutions, which set private or public certification standards, can affect firms’ investment in differentiated products because the standard stringency affects the production and compliance costs as well as the level of product differentiation. Hence, through the setting of these standards, private and governmental institutions can impact the market structure as well as the growth of an emerging market. Finally, we discuss policy implications and how an adjustment of the EU-regulatory framework from a process- to a product-based system can make several issues discussed in this thesis problems of the past.

    Adding value through health claims: an empirical analysis of the Italian yogurt market
    Bimbo, Francesco - \ 2017

    In recent years policymakers have aimed to increase the general awareness regarding the link between diet and health, providing food companies with an opportunity to add health-enhancing features in order to differentiate their products. The European market of these products, referred to here as functional foods, is regulated according to the European regulation 1924/2006 on nutrition and health claims on foods.

    Even though the European functional foods’ market has grown steadily over the last 20 years, more than 3 out of 4 new functional products are withdrawn from the market within two years from launch. Indeed, firms have to overcome three main obstacles to market health-enhancing products successfully. First, consumer-related factors, such as the heterogeneity of consumer acceptance of, and preferences for, new functional products; second, firms' difficulties in selecting the optimal attribute profiles to meet consumer demand for health features and; third, firms' difficulties to target consumers with a high enough willingness to pay to ensure the profitability of those investments needed to develop and market functional products.

    The general objective of this thesis is to assess quantitatively the implicit price of health claims as well as to generate new knowledge that will inform firms on how to target consumers with higher WTP for functional products.

    This thesis uses the Italian yogurt market as a case study for three reasons. First, yogurt is considered intrinsically healthy and it is one of the most credible carriers of functional ingredients: the category of fermented functional dairy accounts for nearly 43 per cent of the total functional products’ market. Second, among European countries, Italy saw the launch of the highest number (592) of new healthy products in the period 2005-2009; the majority of the new products introduced were functional yogurts benefiting digestive health (336), the immune system (99) and cardiovascular health (65). Third, the Italian yogurt market is characterized by a high level of differentiation with respect of health attributes, with manufacturers offering a variety of products carrying health claims, appearing suitable to analyze the problem at hand.

    The results of this thesis show that in the Italian yogurt market the implicit prices of “risk reduction” claim is higher than that of “general function” ones (respectively, +222.6% vs +85.5% of the baseline alternative’s price in the case of cholesterol reduction health claim), and in three out of four cases, health claims supported by familiar brands have higher implicit price than those supported by less-familiar ones. Those results confirm findings collected in the systematic literature review which highlights a consensus that claims supported by familiar brands as well as “risk reduction” (vis-à-vis “general function”) ones increase consumers’ acceptance of functional dairy products. The results also point out that “natural” and “organic” claims lead to implicit prices which are (approximately) +46.6% and +102.0% over the price of the baseline alternative, comparable to those of some of the health claims. Other results indicate that manufacturers operating in the Italian yogurt market investing in credence attributes (health claims, organic and natural) gain the ability to target consumers with higher WTP by including two or more products carrying credence attribute in their portfolio. Lastly, the findings of this thesis reveal that consumers’ body image dissatisfaction, along with not reading food labels and lower knowledge about leading functional yogurt brands, are associated with lower number of functional yogurt packages purchased by Italian yogurt consumers using a virtual shelf setting.

    The twenty-first century has witnessed a fundamental reform of food law in the European Union, to the point where modern EU food law has now come of age. This book presents the most significant elements of these legal developments with contributions from a highly qualified team of academics and practitioners. Their analysis is based on a shared vision of the structure and content of EU food law. The book takes the perspective of food law embedded within general EU law. It highlights the consequences of this combination and provides insights into both substantive and procedural food law. Taking the General Food Law as a focal point, this handbook analyses and explains the institutional, substantive and procedural elements of EU food law. Principles are discussed as well as specific rules addressing food as a product, the processes related to food and communication about food to consumers through labelling. These rules define requirements on subjects like market authorisation for food additives, novel foods and genetically modified foods, food hygiene, tracking & tracing, withdrawal & recall. The powers of public authorities to enforce food law and to deal with incidents are outlined. Attention is given to the international context (WTO, Codex Alimentarius) as well as to private standards. In addition to the systematic analysis, the book includes selected topics such as nutrition and health policy, special foods, food import requirements, food contact materials, intellectual property and animal feed.

    The transition from domestic to market economy in rural areas of Europe is an ongoing process that affect and is affected by local and global dynamics. The outcome of this process is unique, but if we analyse and compare each case, it is possible to find patterns and common tendencies. This book highlights the unique and common elements of these transitions, and in order to do so, it takes as reference one case from the south of Europe, the attempt to achieve a PDO certification for local cured sheep cheese, and other from Western Europe, the design and unfold of a Regional Label for local lamb meat. The thesis of this book underline is the existence of a “quality turn” in Europe, and analyse how Origin Food Labels can instruments to institutionalise new forms of co-production and co-evolution that enhance sustainable territorial development. At the same time, the ethnographic nature of this research highlights that these are controversial and political processes, where local and non-local actors with different interests find each other and try to unfold their own projects. The use of a comparative strategy highlights how these transitions are influenced by local institutional frameworks and cultural patterns, but it also shows how collective action can change them.

    By stating the origin of a foodstuff, producers can provide consumers with information about where the food comes from. Country of origin labelling is the subject of debate from two different policy areas. One debate takes place in the framework of EU quality policy for agricultural products, the other in the framework of EU consumer policy. In one debate, origin labelling is regarded as a trade norm, while the other considers it part of food information which allows consumers to make well-founded choices between foodstuffs.

    Met het vermelden van de herkomst op een levensmiddel kunnen producenten informatie geven aan consumenten over de plaats waar het voedsel vandaan komt. Herkomstetikettering staat vanuit twee verschillende beleidsterreinen ter discussie. De ene discussie vindt plaats in het kader van het EU-kwaliteitsbeleid voor landbouwproducten; de andere in het kader van het EU-consumentenbeleid. In de ene discussie wordt herkomstetikettering als handelsnorm gezien; in de andere als onderdeel van voedselinformatie waardoor consumenten doordachte keuzes tussen levensmiddelen kunnen maken.

    The impact of food allergy on household level

    Adverse reactions to food can be caused by food hypersensitivity. Prominent examples include food allergy or food intolerance. Patients suffering from food hypersensitivity have inappropriate autoimmune system reactions to potentially harmless food components. Symptoms can vary from uncomfortable skin rashes to cardiovascular problems such as anaphylactic shock. To date, no general cure is available. As a consequence, the management of food allergy consists of allergen avoidance, which may cause negative consequences in terms of patient anxiety and their experience of quality of life. Furthermore, implementation of dietary restrictions can have a negative effect on the quality of life and economic functioning of not only the food allergic patient but also their family members.
    An important issue in the assessment of the impact of food hypersensitivity and food allergy is the assessment of the economic costs that accrue to afflicted consumers. This information will contribute to the prioritising of healthcare resources, as well as developing effective policies to insure consumer protection. It is also important to evaluate whether wellbeing and welfare are affected. If this is indeed the case, a question arises as how to best manage dietary avoidance strategies. The aim of the research reported in this thesis is to provide information salient to the assessment of the impact of food hypersensitivity and allergy on households with respect to costs (time and money), welfare, well-being, and information search strategies.
    A systematic review of the existing literature revealed that researchers had not yet developed and validated an instrument to measure the individual and household costs of food hypersensitivity and/ or allergy. This thesis describes the development of the “household costs of food allergy” questionnaire and the exploratory analyses applied to validate the instrument. Thereafter, the “household costs of food allergy” questionnaire was used on a large sample of clinician-diagnosed food hypersensitive patients to confirm these cost effects. This study was part of an epidemiological study to investigate the prevalence of food allergy and food intolerance in four European countries, data were collected in The Netherlands, Poland, Spain and the United Kingdom. The respondents in this study were either diagnosed with food allergy or food intolerance. For the purposes of this discussion, the term food hypersensitivity will be used to indicate both diseases. Contrary to expectation, households with food hypersensitive respondents had significantly lower direct and indirect costs across all countries compared to households without food hypersensitive members. In addition, no differences in welfare between food hypersensitive respondents and respondents asymptomatic to foods were found. However, adult food hypersensitive respondents and their spouses reported significantly less happiness than respondents, or their spouses, who were asymptomatic. Thus, the results presented in this thesis do not support the commonly held belief of clinical researcher and patient organisations that all food allergies incur high costs to the individual.
    Given that an individual’s experience of quality of life is negatively impacted by food hypersensitivity, it is feasible that this might be improved by the implementation of more effective management strategies. As the primary viable management strategy involves avoidance of problematic foods, facilitating consumer choice in the retail environment may optimise risk management. The labelling preferences of food allergic consumers were investigated in two European countries, The Netherlands and Greece. At the time the research was conducted, food legislation had been developed to facilitate management of food allergens in order to protect food allergic consumers, rather than food intolerant consumers. For this reason, the research was confined to the study of the information needs of food allergic patients, and how this related to the current legislative situation. The research utilised ethnographic interviews with food allergic consumers during the course of shopping in a supermarket. The results suggest that current labelling practice is perceived to be inadequate for food allergic consumers if safe food choices are to be made. This is due to inappropriate use of fonts, colours with low contrasts and inconsistencies in the different languages, application of precautionary labelling, and lack of European and international harmonisation in labelling legislation. Based on these results, new information scenarios, such as uniform labelling, information booklet and ICT solutions, were developed and tested through an online survey. The results were used to develop prototype information delivery tools. An experiment was conducted to understand if the information delivery was in fact optimal, and to confirm if the additional attributes of the prototype tools were sufficient to facilitate allergen avoidance. The results suggested that the label should show the percentages of the allergens in the food product, as well as provide specific details about allergy management in the food chain, and use standardised symbols and standardised location of allergy information on the package. Additional visual and auditory warnings were also treated as being important for the ICT driven information delivery approaches, the results indicated that ICT methods are not appropriate replacements for effective food labelling on packaging, but may be used to supplement information provided by labels.
    To conclude, this thesis provides insight in the financial impact of food hypersensitivity, as well as the welfare and well-being. The “household costs of food allergy” questionnaire can be used by regulators and policy makers to prioritise healthcare resources, as well as to test the effectiveness of policy interventions. Limitations in current risk management strategies based on consumer information were also identified. The results of the consumer preferences studies can be used by policy makers and food industry to optimise the information delivery to food allergic consumers and therewith improve their quality of life. The combination of economic research and consumer research is relevant to investigate the dynamic impact of food allergy on individuals and their families.
