Artigo Científico How do transaction costs, capabilities and networks influence the procurement strategies of small agri-food firms? Evidence from the wine industry(2022) BRUNO VARELLA MIRANDA; Ross, Brent; Franken, Jason; Gómez, MiguelPurpose – The purpose of this study is to disentangle the drivers of adoption of procurement strategies in situations where small agri-food firms deal with constrained organizational choices. More specifically, the authors investigate the role of transaction costs, capabilities and networks in the definition of feasible “make or-buy” choices in emerging wine regions. Design/methodology/approach – This article analyzes a unique dataset of small wineries from five US states: Illinois, Michigan, Missouri, New York and Vermont. The reported results derive from both a hurdle model (i.e. a probit model and a truncated regression model) and a tobit model. Findings – The results suggest the importance of trust as a replacement for formal governance structures whenever small firms deal with highly constrained sets of organizational choices. On the other hand, the level of dependence on a limited mix of winegrape varieties and the perception that these varieties are fundamental in building legitimacy help to explain higher rates of vertical integration. Originality/value – This study is important because it sheds light on organizational constraints that affect millions of farmers across the globe. The study of “make-or-buy” decisions in agri-food supply chains has mostly relied on the implicit assumption that all organizational choices are available to every firm. Nevertheless, limited capabilities and the participation in low-density networks may constrain the ability of a firm to adopt a governance mechanism. Stated organizational preferences and actual organizational choices may thus differ.Artigo Científico Plural forms and differentiation strategies in the agri-food sector: Evidence from the U.S. wine industry(2022) BRUNO VARELLA MIRANDA; Ross, Brent; Franken, Jason; Gómez, MiguelThis article investigates how measurement ability, trust, and the pursuit of differentiation strategies influence the adoption of plural forms in an agri-food system. We analyze a unique dataset of 314 winegrape sourcing choices from 74 wineries located in five U.S. states, investigating how the pursuit of differentiation influences the likelihood of adoption of a plural form—that is, the simultaneous adoption of a formal arrangement (i.e., vertical integration or long-term formal contract) and an informal arrangement (i.e., informal contracts or spot-market transactions). Consistent with previous studies, measurement ability and the existence of trust are both associated with a higher likelihood of adoption of informal arrangements in comparison to formal arrangements. Moreover, we show that the likelihood of adoption of a plural form increases as the differentiation potential of a winegrape variety also increases. Finally, we find that the use of plural forms is associated with a reduction in the importance of trust in the relationships with external suppliers. This study is important because it sheds light on the role of plural forms in the pursuit of competitive advantage in an agri-food system. Overall, it suggests that the current interpretations of the idea of “vertical coordination” may be enlarged to encompass a greater deal of organizational diversity.
