Abstract

Purpose

The purpose of this study is to explore the mortgage affordability problem in Ghana, an issue that has been associated inter alia with high mortgage rates, which results from the high cost of capital, an unstable macroeconomy and unfavourable borrowers’ characteristics. Concurrent improvements in both the macroeconomy and borrowers’ characteristics have rendered the identification of the most problematic mortgage pricing determinant difficult, consequently making the targeting of policy interventions problematic.

Design/methodology/approach

This research sought to resolve this aforementioned difficulty by providing empirical evidence on the relative importance of mortgage pricing determinants. A data set of mortgage rates of selected Ghanaian banking financial institutions from 2003 to 2013 was examined and analysed by applying Fisher’s model of interest rates and an ex post analysis of the standard regression coefficients.

Findings

The risk premium factor emerged as the most important determinant in Ghana compared with the inflation premium and the real risk-free rate, although all are statistically significant and strongly correlated with mortgage rates.

Originality/value

This study provides an insight on the relative importance of mortgage pricing determinates and subsequent macro-economic guidance to support policy interventions which could reduce mortgage rates/enhance mortgage affordability. The paper specifically aims to engender wider debate and provide guidance to the Ghanaian Government and/or private enterprises that seek to provide affordable mortgages. Further research is proposed which could explore ways of reducing mortgage rates as a means of engendering social equality and adopt innovative international best practice that has already been tried and tested in countries such as South Africa and the USA.

Abstract

Purpose

In this paper, the authors introduce supply disruption ambiguity as the inability of a sourcing firm to attach probability point estimates to the occurrence of and to the magnitude of loss from supply disruptions. The authors drew on the “ambiguity in decision-making” literature to define this concept formally, connected it to relevant supply disruption information deficit, positioned it relative to supply chain risk assessment and hypothesized and tested its negative associations with both supply base ties and inventory turnover.

Design/methodology/approach

The authors analysed survey data from 171 North American manufacturers and archival data for a subset (88 publicly listed) of these manufacturers via Ordinary Least Squares (OLS) estimation after ensuring that methodological concerns with survey research have been addressed. They used appropriate controls and employed the heteroskedasticity-based instrumental variable (HBIV) approach to ensure that inferences from our results are not unduly influenced by endogeneity.

Findings

Strong supply base ties decrease supply disruption ambiguity, which, in turn, increases inventory turnover. Moreover, strong supply base ties and data integration with the supply base have indirect and positive effects on inventory turnover. As sourcing firms strengthen ties and integrate data exchange with their supply base, their inventory turnover improves from access to information relevant to detect and diagnose supply disruptions effectively.

Originality/value

Research on supply disruption management has paid more attention to the “disruption recovery” stage than to the “disruption discovery” stage. In this paper, the authors add novel insights regarding the recognition and diagnosis aspects of the “disruption discovery” stage. These novel insights reveal how and why sourcing firms reduce their overall ambiguity associated with detecting and assessing losses from supply disruptions through establishing strong ties with their supply base and how and why reducing such ambiguity improves inventory turnover performance.

Abstract

Purpose

Catastrophic supply chain disruptions can significantly damage the operational and financial performance of firms. While a growing body of literature on supply network structures has studied what influences supply networks' vulnerability to supply chain disruptions and capability to recover from them, it remains unclear how supply network structures change after major supply chain disruptions. We aim to provide an understanding of how these changes occur.

Design/methodology/approach

Using a natural experiment approach and supply network data from Factset, this study investigates how firms' supply network structures change after experiencing the catastrophic supply chain disruptions caused by the 2011 Tohoku earthquake and tsunami in Japan. We capture post-earthquake supply network changes using the measures of degree centrality and ego network density.

Findings

The results of the analysis suggest that compared to unaffected firms, the affected firms experience changes in their supply network structures tending toward lower complexity measured by in-degree centrality, out-degree centrality and ego network density.

Originality/value

This study contributes to social network theory and the complex adaptive supply network literature by providing empirical evidence of structural changes in supply networks after catastrophic supply chain disruptions. A managerial contribution is made by providing a reflection on why these changes might be occurring and alert firms to the challenges of managing complexity in their supply networks.

Abstract

The impact of COVID-19 on the lives of people and businesses across the globe was devastating. While governments across the world had undertaken a slew of measures to control the spread of the COVID-19 virus within their geography, many of these measures had long and unintended consequences. The restrictions imposed by the governments on the movement of people and goods across the world brought supply chains to a grinding halt. This study identifies the cascading effects of supply chain disruptions (SCDs) on the energy sector and thereby on the security of supply of energy from a European Union perspective. Since these systems are closely integrated and the impact of COVID-19 needs to be analysed at a much broader level, this study uses a systems-thinking approach to study the effect of SCDs on energy services. The study develops a causal loop model to gain further insight into how SCDs caused by COVID-19 affected the coping capabilities of society and how critical services were affected. Furthermore, the study puts forth certain policy recommendations for both businesses and governments to prepare for and protect against a similar situation in the future.

Abstract

Purpose

Organizations increasingly rely on cross-functional teams to deal with supply chain (SC) disruptions. These teams may use their broad range of connections and expertise to gather or scout relevant information, enabling them to develop integrative countermeasures and increase their organization’s resilience. Despite their potential, cross-functional teams often struggle to attain information scouting’s prospective benefits for effectively resolving disruptions. By drawing from group information-processing theory, this study aims to explore when and how cross-functional teams can realize information scouting’s full potential for ensuring their organization’s resilience.

Design/methodology/approach

Multisource, multi-informant data were collected from 80 cross-functional teams exposed to SC disruptions in a realistic SC management simulation.

Findings

The results show that a cross-functional team’s ability to effectively use information scouting for ensuring its organization’s resilience is contingent upon the degree to which the team’s members share information and align decisions internally (i.e. internal integration). The findings further reveal that this moderating role of internal integration is strengthened when the cross-functional team faces a volatile environment in which multiple SC disruptions are likely to occur (i.e. higher SC vulnerability).

Originality/value

This study contributes by advancing a more complete perspective on how a cross-functional team may contribute to its organization’s resilience. Specifically, the present research reveals how the benefits of a cross-functional team’s information scouting for dealing with SC disruptions are critically dependent upon internal conditions within the team, as well as external conditions related to its organization’s overall SC (i.e. beyond individual dyadic relationships).

Abstract

This paper explores sustainability within supply chain management and its link towards resilience through the lens of ethics. The wicked problem of sustainability impacts supply chains and society at large, and the ability of supply chains to remain viable in the future is based on the sustainability of business practices. The paper argues that a substantive proportion of sustainability mechanisms (such as the Triple Bottom Line approach and codes of conducts) can be viewed within the ethical paradigm of deontology, whereby the morality of an action is based on adherence to rules. However, there are numerous critiques of such approaches and their success in creating more sustainable practices. Therefore, the paper proposes there is a need for systems thinking approaches to be incorporated into the exploration of the link between ethics, sustainability and supply chain resilience. Using two examples of social sustainability issues in Australia – modern slavery legislation and horticultural1 worker exploitation – the paper demonstrates the utility of various systems thinking methodologies to explore the complexity of these issues. The paper sets out a conceptual call to arms for researchers and practitioners to apply a holistic lens towards how the morality of actions is shaped and influences supply chain sustainability practices.

Abstract

Purpose

The purpose of this paper is to algorithmically and objectively investigate the previous literature on supply chain resilience (SCR) and advance theory by synthesizing new research domains.

Design/methodology/approach

A two-staged analysis approach, integrating systematic literature review (SLR) with VOSviewer co-occurrence analysis, was applied to the articles published between 2003 and 2018.

Findings

The authors find exponential growth in the literature on SCR over the last decade; however, there is still a gap for empirical research on numerous drivers, barriers, theories, moderators, mediators and research methods intertwined in building SCR.

Research limitations/implications

The review identifies major clusters in which SCR research is conducted and devises a future research agenda based on the findings of co-occurrence analysis.

Practical implications

The findings provide managers with a broad spectrum of factors that are indispensable to build resilience and inform business policy.

Originality/value

While some SLRs exist in the current literature of SCR, the authors undertake a unique analytical perspective, resulting in an idiosyncratic set of research domains for further investigation in the area.

Abstract

Purpose

The lean and global character of supply networks today opens supply chains to potential disruptions, especially in volatile environments. Most disruptions are of relatively low potential impact; however, firms also occasionally face high-impact disruptions that may even threaten survival. This study applies and extends absorptive capacity concepts to organize resilience capabilities identified in the literature and to examine whether capabilities that provide low-impact resilience are different from those that provide high-impact resilience. A second and related objective is to evaluate whether low-impact resilience supports high-impact resilience through “learning by experience.”

Design/methodology/approach

Survey and industry data are used to understand capabilities involved with achieving both low-impact resilience and high-impact resilience.

Findings

The results of our analysis of survey and industry data uncover significant complex interactions in the effects of capabilities and volatility on resilience; suggesting that different absorptive capacity capabilities are related to low-impact resilience and high-impact resilience, respectively, and these effects depend on industry context. Moderating influences of exploitation capability and environmental volatility are consistent with a “learning by experience” explanation of the association of low-impact resilience to high-impact resilience.

Originality/value

This study thus provides a unifying framework with which to consider resiliency capabilities. Further, it answers a question raised in prior research, and it extends our understanding of important relationships between capabilities for different levels of resilience.

Abstract

Purpose

The study of supply chain disruption (SCD) and supply chain resilience (SCR) remains to be studied deeply in the field of business management. The purpose of this paper is to showcase a framework of SCR strategies to reduce the adverse effects of SCD using systematic literature review and data visualization.

Design/methodology/approach

Using a systematic literature review approach, the paper explores the concepts of supply chain disruption and supply chain resilience. Through rigorous systematic screening, authors studied papers on both the concepts and have proposed a framework for the same. The authors also have used data visualization and network diagram approaches for better understanding of the topic.

Findings

The systematic literature review of both the concepts brings out some exciting results which give a new direction to supply chain field. The outcome of this research also outlines numerous future research direction, which will be useful for the research community.

Practical implications

The numerous strategies of SCR should be implemented by manufacturing as well as a service organization. The framework reported in this research help academician and practitioners to understand SCR and to easily overcome any level of disruption. Supply chain managers must also formulate strategies accordingly and make plans to continually expand the system.

Originality/value

This research is the first such attempt to showcase a formal systematic framework and co-occurrence networks as well as overlay networks of SCR and SCD.

Abstract

Purpose

The study analysed the aerospace industry, a traditionally important sector for the topic of risk management, from three complementary perspectives: the supply chain risks present in the sector, the mitigation strategies adopted to face them, and the characteristics (dimensions) observed in the SCRM process of aerospace companies.

Design/methodology/approach

The research employed a quali–quantitative method: a survey was carried out, followed by interviews with professionals from companies belonging to different tiers of aerospace supply chains. Interviews helped to interpret the survey data and understand in more detail risk management in aerospace companies.

Findings

The study presents a panorama of the aerospace industry in terms of risk management. The sector’s turbulent environment is described as well as the strategies to prevent, minimise or postpone the impact of supply chain risks. In particular, ten dimensions that have been identified in the SCRM process of aerospace firms are discussed. These characteristics influence the objectives of this process and are related to resources, roles and responsibilities, incentives, development of competences and skills, scope (internal and external) and approaches to integrate decisions and actions in the context of the supply chain.

Originality/value

Articles that address the SCRM process usually focus on the process steps, whereas this study investigated dimensions that transcend these steps but whose discussion in the literature is still fragmented. It also analysed a reference sector for the topic from a broader perspective than others available in the literature (supply chain risks, mitigation strategies and characteristics of the SCRM process). Supply chain members with relationships with each other were investigated, a desirable approach for SCRM but still under-explored. The study also answers calls for industry-specific studies and research on emerging countries.
