    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.

    The EU dairy sector is facing a crisis, which also affects Dutch dairy farmers. Low milk prices have negatively affected dairy farm profitability. At the same time, the structural adjustment in the Dutch dairy sector has slowed down: the reduction in the rate of farm exits was below normal levels and in contrast with the pattern observed in several other EU Member States. Now the Dutch government would like to consider a temporary support programme aimed at restructuring the dairy sector. The Ministry of Economic Affairs has requested Wageningen Economic Research to provide a background analysis with respect to such a temporary measure. This analysis is requested because the proposed measure would imply state aid to the Dutch dairy sector, which is only allowable in case a number of criteria are satisfied. This research should provide insight into this matter.

    Het project Marktgericht Ondernemen (2012-2015) heeft als doel om de positie van telers en ketenpartners in de tuinbouw te versterken. Via verschillende sporen is er gewerkt aan het creëren van (nieuwe) waarde omdat een lage kostprijs alleen niet meer voldoende is om het verschil te maken. Bijvoorbeeld door het ontwikkelen van onderscheidende producten, productconcepten en duurzame verdienmodellen, het vertalen van markt- en consumententrends naar marktkansen, het versterken van ondernemerschap en het aanjagen van een cultuurverandering. Het project heeft een aantal inzichten opgeleverd. Deze inzichten zijn niet alleen relevant voor tuinbouwondernemers, maar feitelijk voor iedereen binnen de Topsector Tuinbouw & Uitgangsmaterialen die zich betrokken voelt bij het innovatiethema ‘Samenwerkende waardeketens’.1 Dit document is een verslag van vier jaar innoveren en exploreren met ondernemers. Een gezamenlijke ontdekkingstocht die niet stopt na het afsluiten van dit project.

    Key Words: Social Venture Entrepreneurs, Exit, Ownership

    Social Venture Entrepreneurs invest in local and mostly bottom of pyramid (BoPs), and more so in developing economies. Different understanding and meanings given to the term exit and ownership, by social venture entrepreneurs and local communities with varied cultural business practices, are highlighted in this thesis. Results from this thesis show that it is important to factor in local and cultural practices into current social venture business models. This will help to ensure the sustainability and scale up of social ventures.

    The study explores exit options within business and development management literature. There were limited scientific related social entrepreneurship literatures on the subject matter at the inception of this study. The choice to conduct a qualitative case study was made in order to bring to out the forms and meanings of exit, as well as perceived exit, and ownership forms expected or anticipated by both the social venture entrepreneur and related stakeholders, such as communities and local partners, covered in this study

    Moringa trees in Bangladesh and in other developing countries have great potential in terms of nutrition security and income generation, but often seem to be underutilized. The European market does offer opportunities for those suppliers that are willing to, and capable of, meeting EU regulations. However, entering the EU market for some developing countries like Bangladesh seems to be farfetched at the time of writing. Firstly, awareness around the nutritional value and market potential of Moringa products needs to be raised so farmers and households begin to maximise the returns of Moringa trees. Secondly, a detailed cost and benefit analysis around a Moringa production company should be conducted. Thirdly, upcoming suppliers need to get acquainted with the regulations and standards required when targeting the export market. This also means that suppliers should establish, and nurture, trading relationships with EU importers or even intermediaries since the volume supplied is likely to be limited according to European terms.

    This thesis aims to advance the understanding of identities and roles of Alternative Food Networks (AFNs). It focusses on AFNs which operate in contexts where traditional aspects are still dominant within the local agrifood systems, and which act on both food provisioning and raising awareness about civic issues. This research examines the identities and roles of AFNs by shedding light on the dynamics of the organisation and implementation of their activities. For this, the thesis firstly adapts a theoretical and methodological framework – Interaction Ritual (IR) theory - for the investigation of social phenomena, starting by unveiling the functioning of their internal dynamics; secondly, it operationalises and applies the selected theoretical and methodological framework in order to analyse GAS M which is a case of an AFN. Namely it is a case of ‘Gruppo di Acquisto Solidale’ (Solidarity Purchasing Group - GAS).

    Below the main contributions and recommendations of this research are synthesised.

    1) This research contributes to the body of knowledge on AFNs by generating insight into the identity of an AFN which operates in a context of a traditional agrifood system, attributes to both consumers and consumer-based civil society organisations leading roles, and works on both food provisioning and activities of civic relevance. The research demonstrates that the identity of GAS M is not clearly defined. Instead, it is continuously re-shaped in response to the varying combination of material and civic activities and interests. The mentioned activities and interests attract different groups of people. It is especially the small group that manages GAS M that is interested in civic activities. Often people in this group choose the organisational arrangements that are in line with their interests so their interests override other people’s interests. GAS M is undergoing a process of ideological and material selection which, together with the pre-eminence of civic interests, has three main implications: a) the equity of the food provisioning system recreated by GAS M is reduced; b) its role as a creator of occasions where producers and consumers can satisfy their needs of buying and selling products with specific physical features is reduced. Furthermore, while its role in building community and creating spaces for socialising and learning is supported, it only reaches people sharing certain interests; c) the durability of GAS M and its likelihood of expansion are limited.

    2) The second result and contribution of this research is theoretical and methodological.

    First of all, the study contributes to refining IR theory. It represents a first attempt to apply the IR model in a study of AFN activities. The research reinterprets IR theory in an explorative and strictly dynamic-centred way. It operationalises the guidelines of IR theory for the collection and analysis of data that result naturally from normal everyday AFN interactions. Furthermore, this approach provides analytical tools to ascertain the intensity of AFNs’ activities, what attracts attention in these activities, which sort of attention, and what its significance is. 

    Secondly, this research has contributed towards advancing the existing body of research into AFN dynamics. Previous studies have focussed on processes of negotiating meaning in order to understand AFN identities and roles. Following IR theory, this research goes beyond the negotiation of meaning by analysing not only the content of interaction but also its intensity. In doing so the study shows not only which issues influence AFN identities and roles, but also which activities play an important role. In addition, the study provides insight into the dynamics of power and inclusivity in AFN interaction that is, among others, reflected in decision making about activities. Unlike previous studies which have looked into these questions by interviewing actors and relying on their rationalisations, this study explores these questions through the analysis of normal every day activities and interactions, and what is also being indicated as ‘natural data’. In this way, this research contributes to overcoming actors’ personal preferences and ideas, which may bias their rationalisations about these matters.

    3) Finally, this research gives some recommendations for further research. It advises to study more cases of AFN in order to check to what extent the results of this case-study may be generalizable.  Furthermore, it offers some inputs on how the approach can be used so as to consider a broader variety of cases in the analysis. Secondly, this research invites future researchers look into what influences the intensity of AFNs’ activities and contributes to their stabilisation, and to explore the causal relationship between civic and material activities and interests.

    In this report the impact of reducing or removing import tariffs on the competitiveness of the EU egg sector is studied. The results show that the offer price of whole egg powder in 2013 of some third countries is close to the average EU price. Despite the current import tariffs on whole egg powder, the third countries can be competitive on the EU market. In a scenario with a 50% lower import tariff, all third countries have a lower offer price of whole egg powder compared to the EU egg sector. In a scenario with zero import tariffs, all third countries have a considerably lower offer price of whole egg powder compared to the EU egg sector.

    Farmers, traders and a commodity exchange -

    institutional change in Ethiopian sesame markets

    Gerdien W. Meijerink

    When one thinks of Ethiopia, sesame is not the first that comes to mind. Sesame, however, is Ethiopia’s second most important agricultural export, and an important income source for many small-scale farmers. Ethiopia’s government established the Ethiopian Commodity Exchange (ECX) to improve the marketing of sesame.

    This study explores the impact of the ECX on the institutions undepinning sesame markets, by interviewing farmers and traders before and after the ECX became mandatory for sesame trade in 2009. It finds that the ECX improved transparency in sesame markets, and as a result improved farmers’ beliefs about opportunistic behaviour of traders, and farmers’ willingness to establish long-term relational contracting with traders. It finds however, that the ECX deteriorated the social capital relations between traders, resulting in a decrease in trade credit between traders.

    Boeren, handelaren en een goederenbeurs -

    Institutionele cerandering in Ethiopische sesam markten

    Gerdien W. Meijerink

    Denkend aan Ethiopië, is sesame niet het eerste dat opkomt. Toch is sesam het twee na belangrijkste export product van Ethiopië en een belangijkre bron van inkomsten voor veel kleinschalige boeren. De overheid van Ethiopië heeft de Ethiopische Goederen Beurs (ECX) opgericht om de marketing van sesame te verbeteren.

    Deze study verkent de invloed van de ECX op de instituties die sesam markten ondersteunen, door boeren en handelaren te interviewen voor en na het verplicht worden van de ECX voor sesamenhandel in 2009. Het vindt dat de ECX de transparantie in sesam markten heeft verbeterd, waardoor het beeld dat boeren hebben over opportunistich gedrag door handelaren verbeterde, en waardoor boeren sneller geneigd zijn op langere termijn een contractrelatie met handelaren aan te gaan. Het vindt daarentegen ook dat de ECX sociaal kapitaal relaties tussen handelaren heeft doen verslechteren, waardoor er minder handelskrediet tussen handelaren verstrekt wordt.
