    Buyer-Supplier Integration and Logistics Performance in Health Care Facilities in Tanzania
    (2015) Salema, Gladness; Buvik, Arnt
    Purpose This research concerns logistics performance in public purchasing relationships, and explores the effect of buyer-supplier integration on supplier logistics performance. The research focuses in particular on purchasing centralization in health care facilities, and examine whether centralization of purchasing decision control exercised by the health authorities will influence the effect of buyer-supplier integration on supplier logistics performances at the firm level in health care facilities. Design/methodology/approach This research is based on basic organization theory, inter-organizational theory, and supply chain management literature, and examines the combined effect of purchasing centralization and supplier integration on supplier logistics performance based on survey data from 164 key informants from public health institutions in Tanzania. Findings The analysis reveals that stronger buyer-supplier integration improves supplier logistics performance significantly, and that stronger centralization of purchasing decision control by the health authorities reduces the effect of more extensive buyer supplier integration on supplier logistics performance at the firm level. Research limitations/implications Public health institutions in Tanzania are highly regulated and controlled by public authorities, and this might limit the external validity of this study. Possible effects of opportunistic behaviour among public agents might also influence the outcome of the analyses, and further research in other empirical settings and cultural settings is desirable to test the external validity of the empirical findings. Practical implications The local government should focus more on supporting the individual public health facilities in developing and adapting proper governance mechanisms for their supplier integration, and be aware of the advantages associated to the alignment of independent and local supplier coordination at the institutional level. Social implications Strong bureaucratic decision control and possible opportunistic behaviour among public agents and employee in public medicine institutions might represent a threat against a smooth and effective organization of the medicine supplies in the public sector. Original/value The study provides a valuable theoretical contribution to the supply chain management research. In particular, the combination of significant contributions from basic organization theory, principal-agent theory and supply chain management literature provides a broad and interesting focus on significant antecedents to supplier logistics performance.

    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 product quality uncertainty on quality-screening efforts: does the purchase frequency and procurement channel choice matter?
    (Inderscience Publishers, 2018) Kanani, Renger; Buvik, Arnt
    Product quality uncertainty is one of the major concerns for buyers in online transactions. In fact, research into the consequences and control of this uncertainty in online transactions has increased considerably in recent years. However, product quality uncertainty poses challenges not only to online buyers, but also to offline buyers. Therefore, the objectives of this empirical study were to examine the effect of product quality uncertainty on quality-screening efforts in offline transactions, and whether the frequency of purchase from the same source and the choice of procurement channel may be used as control mechanisms to reduce this effect. Empirical evidence from 239 small food-processing firms shows that product quality uncertainty has a positive effect on quality-screening efforts. Moreover, our findings demonstrate that this effect decreases significantly when food processors purchase frequently from the same source, and when they buy directly from the farm rather than through intermediaries.

    Effects of product perishability, supplier geographical distance and supplier quality performance on Buyer control in agriculture supply chains
    (InderScience Publishers, 2020) Kanani, Renger; Buvik, Arnt
    The purpose of this study is to investigate the effect of the degree of produce perishability on buyer control and examine this effect across different levels of supplier distance and supplier quality performance. This study was motivated by the vulnerability of quality of perishable agricultural produce to various logistical and transportation activities, including packaging of products, loading, and offloading activities. Three hypotheses capturing our research variables were developed and tested by using data obtained from the owner managers and decision makers in the food processing industry. Empirical evidence from 239 food processing firms revealed that the degree of produce perishability positively influences buyer decision to control food supply chain factors that are likely to affect the quality of agricultural produce. The findings demonstrated further that the effect of produce perishability diminished as supplier geographical distance and quality performance increased.

    The impact of buyer-supplier integration on supplier logistics performance in the hospital sector in Tanzania: the moderation effect of buyers’ cross functional integration
    (Inderscience Enterprises Ltd, 2016) Salema, Gladness; Buvik, Arnt
    Based on the resource-based view (RBV) theory, this study examines the association between buying firms’ cross functional integration, buyer-supplier integration and supplier logistics performance in buyer-supplier relationships. RBV considers these two organisational dimensions of supply chain integration as strategic resources which play an important role in improving logistics performance. This research examines the effects of both intra-firm integration and inter-firm integration on supplier logistics performance with survey data from key informants in the public medicine supply system in Mainland, Tanzania. The unit of analysis is the purchasing relationships between public health facilities and focal suppliers acting as public agents of the national medical stores department (MSD). The empirical analysis is based on data reported by 166 purchasing managers, and demonstrates that stronger buyer-supplier integration improves supplier logistics performance significantly. There is no main effect of the buying firm’s cross functional integration on supplier logistics performance, but more extensive cross functional integration in the buying firms enforces the effect of buyer-supplier integration on supplier logistics performance significantly, and these findings indicate that extensive cross functional integration in the buying firms provides an administrative infrastructure that enhance the effectivity of extensive supplier-buyer integration.
