ItemComitês de Resolução de Disputas (Dispute Boards) nos contratos da administração pública: análise de eficiência, potencialidades e melhores práticas(2022-02-15) Domingues, Igor Gimenes AlvarengaThe present dissertation seeks to analyze the efficiency, potential and best practices in the use of Dispute Boards in Public Administration contracts. Therefore, the work is based on international experience to point out the origin, basic characteristics, and modeling of the use of the mechanism, which is recommended by the main international organizations and associations that are dedicated to its study. Next, an analysis of a vast database with several infrastructure projects that adopted the Dispute Board is carried out, in order to ascertain the concrete results proven by its use. In the second part, the study focusses at the national reality, pointing out the reasons that justify the use of the Dispute Board by the Public Administration, in addition to the estimated costs and types of contract in which its use makes sense. It also assesses the history of its implementation in national contracts, the supporting legislation that currently exists and on-going bills in the National Congress. Closing this part, the study evaluates some real cases in which courts and control agencies analyzed the mechanism. The third part of the work addresses the structuring of Dispute Board clauses in public contracts, with propositional recommendations. Finally, some points with a high potential for dissent are highlighted, suggesting actions to minimize risks. The dissertation follows a hybrid research model based on problem solving and best practices. ItemPower, governance, and value in collaboration: differences between buyer and supplier perspectives(Wiley, 2017-04) Brito, Renata Peregrino de; Miguel, Priscila Laczynski de SouzaEarly research on buyer-supplier relationships was based on two cornerstones: relational governance mechanisms and superior value creation for the whole supply chain. Relational governance mechanisms, based on trust and informal safeguards, can lead to higher value creation, while lack of trust and opportunism can be controlled by contractual governance mechanisms. To date, however, few studies have investigated the role of power asymmetry in collaboration and how the total value is distributed between buyer and supplier. The amount each partner appropriates depends on their relative power in the relationship, which has further implications in governance and relationship continuation, yet that has not been thoroughly explored in the literature. To fill this gap, this study investigates the influence of power asymmetry on governance and value appropriation in collaborative relationships, from both the buyers' and suppliers' perspectives. This article contributes to the buyer-supplier literature by exploring the gains of both the stronger and weaker partners in the dyad. Based on in-depth case studies with buyers and suppliers of the personal care and cosmetics (PC&C), and food and beverage (F&B) industries in Brazil, we found insights concerning the influence of power asymmetry and interdependence on governance mechanisms, as well as the complementarity of value appropriation inside and outside the dyad. We also propose a framework to represent the interplay between perceived justice and power asymmetry in long-term relationships.
