    Buyer-supplier integration and logistics performance in healthcare facilities in Tanzania: the moderating effect of centralised decision control
    (Inderscience Enterprises Ltd, 2018) Salema, Gladness; Buvik, Arnt
    This research concerns logistics performance in public purchasing relationships. It examines the effect of buyer-supplier integration on supplier logistics performance. Particularly focuses on purchasing centralisation in healthcare facilities, and examine whether centralisation of decision control exercised by the health authorities influence the effect of buyer-supplier integration on supplier logistics performance. A survey data of 164 informants from public health facilities in Tanzania was used for analysis. It reveals that buyer-supplier integration improves supplier logistics performance significantly and stronger purchasing centralisation reduces the effect of buyer-supplier integration on supplier logistics performance. It provides a broad and interesting focus on significant antecedents to supplier logistics performance. In the future, the government should focus more on supporting the individual public health facilities in developing and adapting proper governance mechanisms for supporting buyer-supplier integration. Further research in other empirical and cultural settings is desirable to test the external validity of these findings.

    THE EFFECT OF OUTPUT MONITORING ON SUPPLIER LOGISTICS PERFORMANCE AND FLEXIBILITY: THE MEDIATING EFFECTS OF BUYERSUPPLIER INTEGRATION IN THE CONTEXT OF ESSENTIAL MEDICINES SUPPLY
    (Business management Review, University of Dar es salaam, 2019) Salema, Gladness
    This paper examines the relationship between output monitoring and supplier performance. It focuses specifically focuses on buyer-supplier exchange relationships in delivering essential medicines in Tanzania, and examines the mediation effects of buyer-supplier integration on supplier’s flexibility and supplier logistics performance. The resource-based view of the firm was used to frame the relationships by considering output monitoring efforts and the buyer-supplier integration as resources aimed to improve performance. A survey data of 111 public-owned health facilities selected randomly after stratifying them into hospitals, health centres and dispensaries was used for final analysis. Structural equation modelling using Smart PLS3 was employed to ascertain the relationship between output monitoring, buyer-supplier integration and supplier logistics performance and flexibility. The research hypotheses focused on both direct and indirect effects. The results revealed that the buyer-supplier integration partially mediates the effects of output monitoring on supplier logistics performance while fully mediating the effects of output monitoring on supplier flexibility. The results of the study imply that buyersupplier integration is critical for multiple dimensions of performance improvement

    THE MEDIATION EFFECTS OF BUYER-SUPPLIER INTEGRATION ON THE RELATIONSHIP BETWEEN SUPPLIER-SPECIFIC INVESTMENTS AND SUPPLIER-OPPORTUNISM
    (Business management Review, University of Dar es salaam, 2017) Salema, Gladness
    This research concerns opportunism in a buyer-supplier relationship. Based on transaction cost and relational contracting theories, it examines the mediation effects of the buyer-supplier integration on the relationship between supplier specific investment and opportunism. Mediation effects were estimated using structural equation modelling based on a survey of 111 key informants in the public health facilities in Tanzania. The unit of analysis is the exchange relationship between the Medical Supplies Department (MSD) and the public health facility. The analysis revealed that the buyer-supplier integration negatively mediates the effects of supplier-specific investments on opportunism. In this research, external validity is limited due to a highly regulated environment; as such, more studies should be conducted in different contexts, e.g. culture. The findings from this study have both managerial and theoretical implications. First, purchasing managers should exert more efforts in developing closer relationship with the supplier to mitigate opportunistic behaviours. Second, the government should consider enforcing MSD to make specific investments not only as a means for solving moral hazard problems but also as a means for encouraging and enforcing the development of close co-ordination between the actors. Theoretically, this paper has contributed to the transaction cost theory by indicating that specific investments may not always stand as direct control mechanisms towards opportunism; instead, they can also lead to the development of other relational mechanisms which are effective in mitigating opportunistic behaviours
