Value chain governance and determinants of governance patterns: an integrated approach The global value chain approach (GVC) draws on Transaction Cost Eco- nomics (TCE) and Network theories, while focusing on the internal logics of sectors, such as industrial structure and production-process characteristics (Bair 2005). The TCE framework pro- vides insights into the factors that deter- mine value chain governance patterns by convening the effect of transaction characteristics (asset specificity, uncer- tainty and transaction frequency) and the associated transaction costs (both ex-ante and ex-post costs of contract- ing) (Williamson 1979). This approach argues that increases in uncertainty and the risks of opportunism result in greater use of complex contracts or vertical integration (Williamson 1991). Complementarily, Network theorists propound that problems as contractu- al hazards need to be managed at the inter-firm level through social mecha- nisms, i.e. trust, trustworthiness, rep- utation, norms, mutual dependence and information exchange (Powell 1989; Jones et al. 1997) that are called ‘mundane’ transaction costs (Gereffi et al. 2005). Institutional economists also suggest that such formal and informal institutions are “embedded” in their cultural and social environment. Hence, they underline historical processes and path-dependency by which specific in- stitutional arrangements emerge in a given context (North 1990). Different forms of social embeddedness raised by network theory refer to the concept of ‘proximity’ which valorizes the re- T he emergence of governance in economics is linked to integra- tion of international trade and disintegration of production (Feenstra 1998). As production is increasingly fragmented across geographical space and between firms, many studies focus on how these fragmentations are coor- dinated and exchanged (Gereffi et al. 2005). While some economists see mar- ket coordination in governance pat- terns, Humphrey and Schmitz (2000) refer to governance as any coordina- tion of economic activities “through non-market relationships”. This relates to various ways of steering activities that are embedded in value chains, not only networks but also more hierarchi- cal forms. Between the two extremes of market and hierarchical governance, three governance modes are identified: “modular”, “relational” and “captive” (Gereffi et al. 2005). In these three gov- ernance modes, lead firms exert their power by coordinating production vis- à-vis suppliers without direct owner- ship of the firms. In agribusiness value chains, such patterns include out-grow- er schemes, contract farming, category management by supermarket suppliers, marketing contracts, and farmer coop- eratives (Humphrey and Memodovic 2006; Moustier 2010). These forms of coordinatio
