| The governance of food markets is a crucial element for efficiency and distributional effects. In this paper, we use a conceptual model to show that this governance itself is endogenous in an environment of weak contract enforcement and imperfect markets, and importantly depends on the value in the chain. We relate the predictions of the theory to empirical evidence on differences in supply chain governance in Africa across different commodity types. In doing so we offer an explanation as why private sector governance systems with interlinked market transactions have emerged for higher value crops but not for staple food crops. We discuss the efficiency and equity effects and the implications for policy. |

| This paper studies the welfare effects of high-value FFV exports from Senegal to the EU. We analyze how the structure of the export supply chain has changed in response to tightening food standards and investigate the impact for the local population. The study yields four important findings. First, we find that public and private food standards in the EU have lead to increased consolidation and increased vertical coordination in the FFV supply chain with a shift away from smallholder contract-based production to integrated estate production. Second, these structural changes have increased the participation of rural households, and especially poorer households, in the supply chains through wage employment on FFV estates. Third, we find that household... |

| Agricultural supply chains are changing globally with pervasive food standards and increased vertical coordination. The impact of these changes for developing countries and for small farmers in those countries is not yet well understood. We analyze the developments in high-standards FFV supply chains and the effects for small farmers and rural households in Senegal. We use a unique dataset derived from company level interviews and household surveys in the main horticulture zone in Senegal. Supply chain restructuring resulted in a shift from contract-farming with small-scale producers to large-scale vertically integrated estate-farming. A comprehensive econometric analysis shows that the restructuring of the value chain has enhanced an equitable... |

| The importance of food standards in global agricultural trade has increased strongly, but the effects are uncertain. Several studies argue that these standards imposed by high-income countries diminish the export opportunities for developing countries and concentrate the benefits of trade with processing and retailing companies and large farms, thereby casting doubt on the development impact of international agricultural trade. Other argue that the standards can be catalysts for growth. In this paper we critically review the arguments and empirical evidence on the link between increasing food standards, developing country exports and welfare in those countries. We conclude that the evidence is often weaker as claimed. We also provide new insights from... |

| Peasant households, especially African rural households, can hold very diversified portfolios of economic activities. Portfolio diversification is often seen as a risk-reducing mechanism and linked with lowering risk at the cost of a lower income. A simple theoretical model of activity choice reveals that factors other than risk might influence the desire to diversity. In addition, binding entry-constraints might exist for certain off-farm activities. An empirical analysis of Ethiopian rural households suggests that entry-constraints are important in explaining portfolio and that diversification can actually result in increasing income. |

| Food and agricultural commodity value chains in developing and transition countries have undergone tremendous changes in the past decades. Companies and property rights have been privatized, markets liberalized, and economies integrated into global food systems. The liberalization and privatization initially caused the collapse of state-controlled vertical integration. More recently, private vertical coordination systems have emerged and are growing rapidly as a response to consumer demand for food quality and safety on the one hand and the farms' production constraints caused by factor market imperfections. In this paper we (a) demonstrate the importance of these changes, (b) discuss the implications for efficiency and equity and (c) provide empirical... |

| There exists a huge agrifood potential in Ethiopia. However, the country's agrifood supply chains are underdeveloped to deliver quality supply to traders and supplement household livelihoods from the sector. The key factors that determine the proper functioning of supplier-trader chains were not rigorously investigated, at least in the case study area. This paper aims at examining the key determinants in choosing vertical coordination for agrifood products in Tigray, Northern Ethiopia. Structured questionnaires were administered to 247 traders in 10 towns in Tigray. Probit model was employed to identify the key determinants of vertical coordination. Model results show that market information, product characteristics, firm characteristics, and product... |

| This paper uses the framework of subjective wellbeing in order to analyze the welfare implication of rural households involved in modern agri-food supply chain in Senegal. It is argued that small farmers are increasingly excluded from high value commodities chain. There is also evidence that despite increasing standards, vegetable export chain can improve rural households’ welfare through contract farming or by the creation of employment. As an alternative and complementary framework, this paper uses self reported happiness instead of the commonly income-based measure to assess the household welfare. We deal with the potential selection bias of participation. We find that participation in modern agri-export chain as contract farming is not related to... |
