Exploring internal and external supply chain linkages: Evidence from the field

In their pursuit of improved operational performance, organizations in supply chains have sought to develop external information-based linkages with their customers and vendors. Has this course of action been at the expense of developing similar internal information-based linkages? This research explores the specific roles of internal and external information-based linkages in achieving improved operational performance. Based on a single case study that comprises a supply chain containing twenty-four internal and fourteen external linkages this research develops a series of propositions. We find that the individual internal linkages may be useful for extending externally derived visibility, and for addressing to some extent, “structural holes” in the supply chain. Additionally, to extend visibility across the entire supply chain, organizations need to recognize the combining role of internal and external information-based linkages. Finally we offer some thoughts for future research in this area.     

The configuration between supply chain integration and information technology competency: A resource orchestration perspective

Research indicates that deploying appropriate information technology (IT) competency in a manner that fits the supply chain integration (SCI) of a firm induces superior firm performance; however, our understanding of how to empirically conceptualize and assess the performance effect of the fit remains limited. Drawing upon resource orchestration theory and the literature on fit assessment methodologies, our study employs both a contingency and a configuration perspective to conceptualize and operationalize “fit.” The results of a survey of 196 firms in China provide the first empirical evidence for the existence and nature of interrelationships between multiple components of SCI and IT competency and their effects on firm performance. In particular, fit as “moderation” approach indicates that IT competency could strengthen the relationship between SCI and both operational and financial performance. Fit as “profile deviation” approach further reveals that the more similar the IT competency configurations are to those of the top performers in the high-level SCI group, the higher their operational and financial performance are. However, in the medium- and low-level SCI groups, the SCI-IT competency fit is significantly positively associated with financial performance and insignificantly associated with operational performance. The theoretical contributions and managerial implications of the study are discussed.     

The effects of IT-enabled supply chain process change on job and process outcomes: A longitudinal investigation

Prior research on information technology (IT)-enabled supply chain management (SCM) has primarily focused on macro-level issues (e.g., IT capabilities related to SCM, and SCM design and optimization) and outcomes (e.g., firm performance). There has been limited research that focuses on micro-level outcomes related to employees who actually execute SCM processes in organizations. These employee-level outcomes are important because successful implementation of SCM systems and processes hinges on SCM employees’ support and commitment. I develop and test a model positing that SCM employees’ perceptions of changes in their work process characteristics, i.e., process complexity and process rigidity, following a new SCM system implementation will influence their job outcomes, i.e., job performance, job satisfaction, job anxiety, and job security, and their perceptions of process outcomes, i.e., process performance and relationship quality. The model incorporates a holistic appraisal of the extent of change—change radicalness—as a mechanism between work process characteristics and outcomes. The model is supported in three studies conducted in the context of three different SCM system implementations (N = 278, 282, and 304, respectively). In particular, I found that individuals perceived a significant change in their work process characteristics following an SCM system implementation, and changes in work process characteristics had a significant impact on job and process outcomes. These findings contribute to the information systems and operations management literatures and their intersections by offering insights on challenges related to IT-enabled SCM innovation implementation in organizations.     

Evaluating food retailing efficiency: the role of information technology

Information and internet-based technologies have fostered new supply chain initiatives in food retailing but little research has evaluated performance and efficiency impacts. A distance function based on three key performance measures for food retailers is used to evaluate store performance and efficiency. The effects of store format, membership in a chain, unionization, and the adoption of a variety of information technologies. Supply chain technologies are groups into three general categories including data sharing technologies, decision sharing technologies, and technologies that support product assortment, pricing, and merchandising decisions.

Supply chain variability,organizational structure,and performance: The moderating effect of demand unpredictability

Supply chain process variability is the level of inconsistency, or volatility, in the flow of goods into, through, and out of a firm. The research investigates the links among organizational structure (formalization and integration), supply chain process variability, and performance as moderated by environmental uncertainty. We found that in a predictable demand environment, only formal control affects supply chain process variability, leading to improved financial results; but in an unpredictable demand environment, only cross-functional integration affects supply chain process variability, leading to improved financial performance. We also examined whether supply chain process variability is a complete or partial mediator of the relationship between organizational structure and performance, and found that: (1) in a predictable demand environment, supply chain process variability completely mediates the relationship between formal control and performance and (2) in an unpredictable demand environment, supply chain process variability partially mediates the relationship between integration and performance. Supply chain process variability has an inverse relationship with financial performance, regardless of the demand environment; and organizational structure provides managers with the mechanisms to mitigate this variability's detrimental impact on financial performance.     

The link between supply chain fit and financial performance of the firm

The bottom-line financial impact of supply chain management has been of continuing interest. Building on the operations strategy literature, Fisher's (1997) conceptual framework, a survey of 259 U.S. and European manufacturing firms, and secondary financial data, we investigate the relationship between supply chain fit (i.e., strategic consistencies between the products’ supply and demand uncertainty and the underlying supply chain design) and the financial performance of the firm. The findings indicate that the higher the supply chain fit, the higher the Return on Assets (ROA) of the firm, and that firms with a negative misfit show a lower performance than firms with a positive misfit.     

The impact of supply chain integration on performance: A contingency and configuration approach

This study extends the developing body of literature on supply chain integration (SCI), which is the degree to which a manufacturer strategically collaborates with its supply chain partners and collaboratively manages intra- and inter-organizational processes, in order to achieve effective and efficient flows of products and services, information, money and decisions, to provide maximum value to the customer. The previous research is inconsistent in its findings about the relationship between SCI and performance. We attribute this inconsistency to incomplete definitions of SCI, in particular, the tendency to focus on customer and supplier integration only, excluding the important central link of internal integration. We study the relationship between three dimensions of SCI, operational and business performance, from both a contingency and a configuration perspective. In applying the contingency approach, hierarchical regression was used to determine the impact of individual SCI dimensions (customer, supplier and internal integration) and their interactions on performance. In the configuration approach, cluster analysis was used to develop patterns of SCI, which were analyzed in terms of SCI strength and balance. Analysis of variance was used to examine the relationship between SCI pattern and performance. The findings of both the contingency and configuration approach indicated that SCI was related to both operational and business performance. Furthermore, the results indicated that internal and customer integration were more strongly related to improving performance than supplier integration.     

The growth of information workers in the US economy, 1950–2000: the role of technological change,computerization, and structural change

Using data from the decennial US Censuses of 1950, 1960, 1970, 1980, 1990, and 2000, I construct matrices of employment by 267 occupations and 64 industries and then aggregate the occupations into four categories: (i) knowledge producers; (ii) data processors; (iii) service workers; and (iv) goods-processing workers. I find that information workers (the sum of the first two categories) increased from 37% of the workforce in 1950 to 59% in 2000. Then, using an input–output decomposition analysis, I find that the growth in information workers was driven not by a shift in tastes toward information-intensive goods and services (as measured by the composition of final demand) but rather by a roughly equal combination of the substitution of information workers for goods and service workers within the structure of production of industries and the unbalanced growth effect (from differential rates of industry productivity growth). Finally, on the basis of regression analysis, I find that R&D expenditures and computer investment are positively associated with the growth in knowledge workers but negatively associated with the growth of data workers.     

The effect of cross-organizational governance on supply chain resilience: A mediating and moderating model

This study examines the effect of a novel antecedent, namely cross-organizational governance (which can be further divided into contractual and relational governance), on supply chain resilience. Additionally, it explores the mediating and moderating effects of supply chain collaboration and institutional environment, respectively, on the relationship between cross-organizational governance and supply chain resilience. Accordingly, a research model, together with four hypotheses, is constructed based on institutional theory. These are further tested based on data collected from a single-respondent survey of 358 Chinese manufacturing companies. The results reveal that contractual and relational governance have significant positive effects on supply chain resilience; supply chain collaboration plays a partially mediating role and institutional environment plays a moderating role in the effects of contractual and relational governance on supply chain resilience. This study enriches the understanding of the relationships between cross-organizational governance, supply chain collaboration, supply chain resilience, and institutional environment. It also provides a reference for supply chain managers’ decision-making activities.     

Governing buyer–supplier relationships through transactional and relational mechanisms: Evidence from China

Building on economic and social exchange theories, this study investigates the different roles transactional and relational mechanisms have in hindering opportunism and improving relationship performance in an emerging economy. Our study applied to manufacturer–distributor dyads in China and used matched survey data (225 paired sample firms) to test our hypotheses. Our hierarchical multivariate regression and semipartial correlation analyses suggest that transactional mechanisms are more effective in restraining opportunism while relational mechanisms are more powerful in improving relationship performance. This performance is improved more significantly when both contracts and relational norms are used jointly than when used separately. Likewise, opportunism is curbed more effectively when both contracts and trust are used jointly than when used individually.     

The impact of bullwhip on supply chains: Performance pathways,control mechanisms,and managerial levers

Even though few empirical studies have tried to actually explicate the relationship between the bullwhip effect and performance of the supplier firm, there exists a common perception for over 30 years among both practitioners and academics that the bullwhip effect naturally results in decreased firm profitability. Anecdotal evidence further suggests that this decline in profitability arises from a decline in operational performance. However, the results of our study, which empirically examines the bullwhip effect across supply chain partners through an analysis of 383 actual customer base-supplier dyads, challenge this commonly held position by suggesting that while traditional bullwhip often yields reduced ROA, it ultimately has no relationship with the firm's operating margin. Additionally, our results also call into question whether or not production coordination between customers and suppliers can minimize the need for inventory and capacity buffers, which are the two commonly utilized methods for battling the bullwhip effect. Thus the relationship between bullwhip and firm performance is far more nuanced and complicated than previously believed. We also show how the managerial bullwhip levers of coordinating production across supply chain partners, or deploying inventory and capacity buffer control mechanisms, can help maximize a firm's performance along different dimensions.

Demand chain management in manufacturing and services: web-based integration, drivers and performance

This paper investigated the relationship between Internet-enabled supply chain integration strategies and performance in manufacturing and services. It summarizes the literature on demand and supply integration and describes four web-based strategies. A stratified random sample was collected from UK manufacturers and services, and there was strong evidence that demand chain management (DCM) led to the highest performance in manufacturing, but few signs of DCM in services. Manufacturers and services relying on only web-based demand or supply integration outperformed their low integration counterparts, but lagged DCM in manufacturing. The study also investigated DCM adoption drivers and found that rational efficiency and bandwagon effects drove change. The findings have some important implications for theory as well as for manufacturing and service companies interested in improving their performance.     

Supply chain agility: review,classification and synthesis

Supply chain agility (SCA) has emerged as an important capability to remain competitive in this era of business uncertainty and turbulence. This study aims to gain knowledge of the current state of research on SCA, specifically to have conceptual clarity and synthesise future research avenues. To achieve these goals, we have carried out a systematic review of 118 research papers on SCA published from 1999 to 2016. The findings suggest that the domain has witnessed steady growth since its inception, but little consensus has been observed around its definition and boundaries. To counter these definitional ambiguities, we have presented a comprehensive definition of SCA. The paper further discusses SCA along three thematic categories: the first considers SCA from the strategic perspective, the second considers SCA as a capability and focuses on its enablers and the third explores the impact of SCA on performance. Finally, towards the conclusion, a holistic framework summarising the findings is presented.     

Small firms and e-business: cautiousness, contingency and cost-benefit

This paper examines how e-business affects small firms in supply chains. Research in four UK supply chain cases, assistive/medical technology, construction, computer consumables and apparel, indicate widening gaps between large and small firm investment and strategy for exploitation of e-business. Existing models of e-business operationalisation are critically evaluated; and their appropriateness in providing insight and guidance is reflected on. While each model individually provides some useful insights, none are appropriate for examining small firm take up of e-business. Therefore a new framework is developed based on three key issues—cautiousness, contingency and cost-benefit.

Strategic supply management: The relationship between supply management practices, strategic orientation and their impact on organisational performance

A theoretical model is presented for conceptualising the relationship between the management of supply, strategic orientation at the business-unit level and their proposed link with firm performance. The shortcomings of existing approaches in accounting for the wide variety of purchasing practices in a comprehensive supply management framework are discussed as well their alignment with strategic orientation. The paper concludes by presenting a model and propositions concerning firm-level supply management, strategic orientation and firm performance.     

The contingency effects of environmental uncertainty on the relationship between supply chain integration and operational performance

This paper extends prior supply chain research by building and empirically testing a theoretical model of the contingency effects of environmental uncertainty (EU) on the relationships between three dimensions of supply chain integration and four dimensions of operational performance. Based on the contingency and organizational information processing theories, we argue that under a high EU, the associations between supplier/customer integration, and delivery and flexibility performance, and those between internal integration, and product quality and production cost, will be strengthened. These theoretical propositions are largely confirmed by multi-group and structural path analyses of survey responses collected from 151 of Thailand's automotive manufacturing plants. This paper contributes to operations management contingency research and provides theory-driven and empirically proven explanations for managers to differentiate the effects of internal and external integration efforts under different environmental conditions.     

The empirical linkages among market returns,return volatility,and trading volume: Evidence from the S&P 500 VIX Futures

The purpose of this study is to examine the relationships between return and trading volume as well as between return volatility and trading volume by analyzing the asymmetric relationships of contemporaneity and lead-lags between these factors for the S&P 500 VIX Futures Index. We apply the threshold model with the GJR-GARCH framework for empirical analysis herein. The main findings demonstrate that the threshold effects exist in both the contemporaneous and lead-lag relationships between return-volume and volatility-volume. Moreover, the delayed effects of a one-trading-day lag through to three-trading-day lags exist from trading volume to returns and return volatility. Larger trading volume is beneficial for investors to gain returns, but it also leads to higher volatility. The implication of our findings offers a suggestion as to the opportune timing for investors to buy S&P 500 VIX Futures.
