    Impact of financial risk on supply chains: a manufacturer-supplier relational perspective
    (Taylor and Francis, 2020-11-02) Ghadge, Abhijeet; Jena, Sarat Kumar; Kamble, Sachin; Misra, Dheeraj; Tiwari, Manoj Kumar
    This study aims to analyse the manufacturer-supplier relational perspective under the influence of exogenous financial risk. Following corporate finance theory, a multi-objective decision model for supplier selection and order allocation is developed to maximise the total profit of the manufacturer, and minimise the implicit equity stake and financial risk faced by selected suppliers. A two-echelon supply chain is explored under the influence of foreign exchange risk, default risk, market risk and price fluctuation risk, and solved using an NSGA-III algorithm. Three case scenarios are analysed to explore the influence of a set of financial risk on the manufacturer-supplier relationship and the behaviour of suppliers concerning risk profile, both in the short and long-term horizon. The results are analysed from both the manufacturer as well as supplier perspective, and the optimal conditions are discussed under the cascading risk circumstances. The study provides multiple insights into the impact of financial risk on supply chain relationship and will be valuable for dealing with similar uncertain economic environment. The research is likely to be of benefit beyond supply chain managers, like investors and financial risk managers in making informed decisions. The need to focus on systemic risk in supply chains is evident from the study.

    An integrated supply chain – human resource management approach for improved supply chain performance
    (Emerald, 2021-05-11) Jena, Sarat Kumar; Ghadge, Abhijeet
    Purpose Human resource management (HRM) is struggling to cope with the increasingly volatile demand for skilled resources in the logistics and supply chain sector. Thus, this study discovers the possible integration of HRM and supply chain management (SCM) practices for improved supply chain performance. The purpose of this study is to explore the effect of intra HRM–SCM and joint HRM–SCM decisions on the performance of the supply chain. Design/methodology/approach An intra HRM–SCM and joint HRM–SCM model is developed following an empirical study. Survey data collected from 109 supply chain managers from Indian logistics firms are used to test the developed hypotheses. Structural equation modeling is used to analyze and validate the model. Findings The results suggest that supply chain performance is significantly influenced by joint HRM–SCM, compared to intra HRM–SCM practices, especially under volatile demand environments. Training and development, recruitment and selection, and performance management affect joint HRM–SCM significantly compared to the other three factors identified. Moreover, HRM and SCM show strong correlation and mutual support in identifying and fulfilling the demand of the logistics and supply chain sector. Practical implications With a growing trend toward globalization and digitalization, a joint HRM–SCM model will help businesses make robust and informed decisions for improved supply chain performance. Originality/value An empirical relationship between joint HRM–SCM, intra HRM–SCM, supply chain inhibitors and supply chain performance is established in this study. Although some part of this relationship may already exist, the study provides robust evidence to support this complex, collaborative relationship.

    Product bundling and advertising strategy for a duopoly supply chain: A power-balance perspective
    (Springer Verlag, 2020-12-09) Jena, Sarat Kumar; Ghadge, Abhijeet
    The paper studies product bundling in a duopoly supply chain network under the influence of different power-balance structures, bundling decisions and advertising efforts on total supply chain profit. Mathematical models comprising two manufacturers and a single retailer are developed to capture the impact of bundling policy and advertisement strategy under three power-balance structures, namely Manufacturer Stackelberg, Retailer Stackelberg and Vertical Nash. Following game theory models and numerical examples, the study found that the total profit of the supply chain is undifferentiated under the manufacturer Stackelberg and Vertical Nash case in the manufacturer bundling and retailer bundling strategies. However, total supply chain profit under manufacturer bundling strongly dominates under retailer bundling in Retailer Stackelberg and Vertical Nash, and remains valid under multiple settings of market size, price elasticity and advertising elasticity. It is also found that manufacturer bundling is significantly affected by advertising effort compared to retailer bundling. The study contributes to the literature interfacing supply chain and marketing by studying bundling policy and advertising strategy simultaneously for homogenous products, under various power-balance structures and price competition
