This volume consists of seven articles on the role of trust in business-to-business relationships and how it impacts decisions. Business and other researchers from Europe, South Africa, Australia, and the US address the topic in emerging, developing, and developed countries, including the determinants and outcomes of cognitive trust during the expansion phase in buyer-supplier relationships in the US, China, and Brazil; factors that influence initial and future trust for sellers of natural essential oils on e-marketplaces in South Africa; online trust signals used by buyers to assess providers' trustworthiness in the context of industrial services in Austria; how inter-organizational and interpersonal trust are created and how these trust levels can be balanced to create positive outcomes in high-involvement customer-supplier relationships; loyalty strategies used by agri-food industries to maintain distributors; and case-based models of firms' marketing strategies within different context configurations, using the principles of complexity theory.
