Strategies for Developing an Environmentally Sustainable Supply Chain: Differences Between Manufacturing and Service Sectors

This research illuminates the debate on whether there are differences between the manufacturing and service sectors in the matter of developing a sustainable environmental supply chain. Over the past 5 years a survey has been conducted with 800 large European companies, of which half are in the manufacturing sector and half in the service sector. The hypotheses within the survey are related to strategies for developing an environmental supply chain. They were derived from a literature review and were tested by means of a chi‐square test. The survey questionnaire enabled the respondents to give some viewpoints about the hypotheses. In this way, strategies for developing the supply chain such as ISO 14001, the Eco‐Management and Audit Scheme (EMAS), Life Cycle Assessment (LCA), auditing, waste management systems, reverse logistics, environmental indicators, remanufacturing and reuse have been investigated. Results show interesting and unexpected differences between manufacturing and service sectors that can lead to further research, practical implications and even suggestions for the surveyed companies. For instance, the viewpoints of manufacturing and service industries differ over ISO 14001 and EMAS implementation in the supply chain. In addition, service industries approach the implementation of auditing, reverse logistics, reuse and remanufacturing in a way different from that of manufacturing. Other strategies are considered essential by both sectors. Copyright © 2013 John Wiley & Sons, Ltd and ERP Environment.     

Shock and volatility spillovers among equity sectors of the Gulf Arab stock markets

The major objectives of this study are twofold. The first objective is to examine the dynamic volatility and volatility transmission in a multivariate setting using the VAR(1)–GARCH(1,1) model for three major sectors, namely, Service, Banking and Industrial/or Insurance, in four Gulf Cooperation Council (GCC)’s economies (Kuwait, Qatar, Saudi Arabia and UAE). The second is to use the models’ results to compute and analyze the optimal weights and hedge ratios for two-sector portfolio holdings, comprised of the three sectors for each country. The results suggest that past own volatilities matter more than past shocks and there are moderate volatility spillovers between the sectors within the individual countries, with the exception of Qatar. Moreover, the values for ratios of hedging long positions with short positions in the GCC sectors are smaller than those for the US equity sectors. The optimal portfolio weights favor the Banking/financial sector for Qatar, Saudi Arabia and UAE and the Industrial sector for Kuwait.     

A case study of kanban implementation within the pharmaceutical supply chain

This study explores the implementation of the kanban system, which is a Lean technique, within the pharmaceutical supply chain (PSC). The case study provides insights on the benefits and challenges arising from the application of this technique, within a group of cooperative pharmacists, in Greece. The research questions developed from the review of the literature were tested using evidence from field-based, action research within a pharmaceutical organisation. The reported case study contributes to the longer term debate on assessing the Lean maturity level within the health-care sector. There are two primary findings: (i) that the adoption of kanban system provides a strategic benefit and improves the quality of services. (ii) It also provides a basis for a strategy of operational change; it gives the opportunity to the organisation to move away from the current push delivery and logistics systems towards improved logistics strategy models.     

Industrial Property and Structural Change of Manufacturing: a Relative-Cost Analysis

Structural change in manufacturing is gaining momentum in many developed as well as developing cities due to an emerging phenomenon of international division of production. As an advanced developing city-state, Singapore has had the same experience. Labor cost has been an obvious major factor responsible for the structural change in manufacturing since the 1970s. However, having seen that industrial property as a vital factor in manufacturing production is neglected in research, this paper explores the role of the industrial property market in the process of structural change in Singapore's manufacturing sector. On a background of land scarcity and rapid growth, it is found that Singapore industrialists must invest more in premises than previously. There are indications that changing industrial property prices have affected manufacturing groupings unevenly and thus led to structural changes in the use of industrial properties. Space has been transferred from less competitive sectors to more competitive ones due to comparative advantages in its utilization enjoyed by efficient sectors. Therefore, the general trend of rising land costs has contributed, to a certain extent, to the restructuring of Singapore's manufacturing sector.     

Information flows within and across sectors in Chinese stock markets

We examine the patterns of information flows within and across sectors of the two Chinese stock exchanges in Shanghai and Shenzhen during 1994–2001. Using the generalized forecast error variance decomposition, we find a high degree of interdependence, indicating that the sectors are highly integrated and sector prices reflect information from other sectors. Industry is the most influential sector in both exchanges, while Finance in Shenzhen is the least integrated with other sectors. Implications of the findings for investors and policymakers are also discussed.     

WHICH INDUSTRIES TO BAIL OUT FIRST IN ECONOMIC RECESSION? RANKING US INDUSTRIAL SECTORS BY THE POWER-OF-PULL

There have been intense debates regarding which industrial sectors should be prioritized for receiving bailout in economic recessions. This paper takes a network perspective to rank sectors according to the Power-of-Pull (PoP), i.e. a sector's power to pull the overall economy. An eigenvector method is employed to assess the PoP of sectors in the USA, using input–output data from 1998 to 2010. The results support bailout to the motor vehicle sector, but argue against bailout to public infrastructure, health care and information technologies design and service sectors, and also reveal the continual decline of PoP ranking of computer and electronics manufacturing sector over time. These results confirm some but also show little support to some other economic revival policies of the Obama Administration in the USA.     

An Assessment of the Performance of Indian State-Owned Enterprises

We examine the determinants of performance of 68 Indian state-owned enterprises in the manufacturing sector for a five-year period: 1987 to 1991. Relative performance is determined using data envelopment analysis, with variations in performance patterns subsequently explained using regression analysis. We note that the performance of firms in the Indian state-owned sector is characterized by both, low performance, as well as significant and systematic variations in the performance parameters. Size is positively associated and age negatively associated with efficiency. Further, economic liberalization and reforms aimed at improving the performance of state-owned firms induces efficiency gains over time. This heterogeneity within the state-owned sector has policy implications, which we discuss. In countries which have privatized large numbers of their state-owned firms, it is often the larger establishments which have been sold to the public. The state-owned firms in the manufacturing sector that can be candidates for privatization are the smaller and older manufacturing firms. These firms may also be easier to dispose of to private investors. This finding reinforces our central thesis that firm-level analysis within the state-owned sector is useful and important for generating pragmatic policy guidelines.     

Incidence and duration of unemployment spells: Implications for the male–female wage differentials

We demonstrate in this paper that the incidence of unemployment and duration of unemployment spells affect the male–female gender wage differential. The results indicate that after controlling for sample selectivity bias in the wage equation, the incidence of unemployment and duration of unemployment spells account for about 14.2% and 39.6%, respectively, of the wage differential that exists between males and females. We observed that while the duration of unemployment accounts for a substantial portion of the wage differential in both the service (48.8%) and the manufacturing (17.0%) sectors, the impacts of the incidence of unemployment and duration of unemployment spells variables on the wage differential are rather small in the service (0.07%) and the manufacturing (1.6%) sectors. Also, high incidence of unemployments is associated with low wages for males and females in all samples. In contrast, longer durations of unemployment spells tend to increase males’ wages and decrease females’ wages in the full and service sector samples. At the macro level, the results seem to suggest that promotion of gender wage equality should be associated with policies that will minimize the female's incidence of unemployment and duration of unemployment spells.     

Information technologies, embodiment and growth

This paper studies the conditions under which an IT revolution may occur and have permanent effects on long-term growth. To this end, we construct a multi-sectoral growth model with endogenous embodied technical progress. The R&D sector expands the range of softwares. The capital sector produces efficient capital combining hardware with available softwares. Technological progress is therefore embodied: New softwares can only be run on the most recent generations of hardware. The new softwares are copyrighted during a fixed period of time. First, we analytically characterize the balanced growth paths of the model. Then we focus on the dynamic response of the economy to technological shocks. Substitution effects favorable to the IT sectors are shown to arise when positive supply shocks affect the production of efficient capital and/or the creation of new softwares. Positive shocks specific to the capital sector are unable to produce effects on long-term growth, in contrast to the shocks specific to the R&D sector.     

Manufacturing linkages, industrial dynamics and the transmission of growth

In order to identify the ‘propulsive’ industries of Perroux and the industrial hierarchy of Aujac, an interindustry connectivity matrix is set up using interindustry transactions data from the United Kingdom national input-output matrix. By powering this binary matrix a measure of the connectivity of each industrial sector is created. The best-connected industries are found to lie largely within the metal manufacture and engineering sectors. At the same time key industrial sectors which though small in output occupy critical positions within the matrix and the industrial core are identified. The implications of the findings for regional policy are then discussed.     

Foreign direct investment,labour relations and sector effects: US investment outflows to Europe

This paper analyses the impact of national labour relations on foreign direct investment (FDI), with emphasis on macro-markets and sector properties. Since there are sector-specific differences between industries in transferability, labour-relations effects on FDI probably vary across sectors. The paper finds that labour costs dampen FDI, while the impact of national market potential remains inconclusive. Collective labour institutions have a significantly adverse impact on FDI in manufacturing, and a relatively beneficial one on FDI in services. While investment in manufacturing seeks to minimize labour costs at given skill levels, investment in services maximizes skills at given levels of cost.     

Managing ambiguity: merger activity in the nonprofit housing sector

Merger behaviour in the nonprofit sector has been relatively neglected, yet has considerable marketing implications. This paper draws on a range of sources to explore the nature of merger activity in the nonprofit housing industry. It locates mergers within debates about inter-organisational strategies, and explores the context, extent, motivations for and regulation of mergers in the housing industry. While there are many similarities in environmental stimuli to and processes of negotiating mergers between the profit-distributing and nonprofit sectors, there are some distinctive features. This research explores the ambiguous nature of the merger activity among housing organisations. This ambiguity infects the terminology and record-keeping systems and helps to explain a significant gap between rhetoric and activity. Such ambiguity may be more than a negotiating strategy. It may represent the attempt to manage conflicting pressures to market nonprofit organisations as ‘sensitively serving the needs of society’ by on the one hand being competitive and efficient while on the other remaining value based and locally accountable.

Demand chain management: an integrative approach in automotive retailing

Recent reviews of the ‘operations management’ (OM) research literature have shown a surprising little shift towards empirical methodologies from traditional modelling solution methods. In addition, there is generally a lack of empirical testing and validation of manufacturing strategies. Coupled to this fact is that empirical work is rarely carried out in an inter-disciplinary manner, with the complete combination of OM, marketing, strategy, lean thinking and accounting approaches particularly poorly researched. Fully cross-functional integrative empirical research is required to help support the understanding of the applicability of OM practices within industry. This paper explores such an integration of approaches developed within the ‘lean thinking, strategic cost management, marketing and policy deployment areas’. In order to investigate the approach a single automotive retailer is used as an instrumental case. The results of the study show that the new approach stands up well as an integrative approach that can prove highly beneficial results. However, the pilot work also identified a number of limitations that are the basis of further refinement and testing of the method.     

The economy of Portugal within the European Union: 1990–2002

This article analyzes the impact of the EU on Portugal’s economy, how the EU rules and regulations have affected the country’s policy-making style, and the impact of EU’s transfer of resources. It shows that Portugal has greatly benefitted from joining the EU: the rapid exposure to foreign competition has forced modernization of many sectors; there was a retreat of the state from direct involvement in economic activities and the creation of a number of new export-oriented sectors, and EU transfers were effectively applied in modernizing the country’s infrastructure. However, increased productivity has not improved equity from both an income distribution point of view and from regional income concentration.

EFFECTS OF SECTOR AGGREGATION ON CO2 MULTIPLIERS IN MULTIREGIONAL INPUT–OUTPUT ANALYSES

The past few years have seen the emergence of several global multiregional input–output (MRIO) databases. Due to the cost and complexity of developing such extensive tables, industry sectors are generally represented at a rather aggregate level. Currently, one of the most important applications of input–output analysis is environmental assessments, for which highly aggregate sectors may not be sufficient to yield accurate results. We experiment with four of the most important global MRIO systems available, analyzing the sensitivity of a set of aggregate CO₂ multipliers to aggregations in the MRIO tables used to calculate them. Across databases, we find (a) significant sensitivity to background system detail and (b) that sub-sectors contained within the same aggregate MRIO sector may exhibit highly different carbon multipliers. We conclude that the additional information provided by the extra sector detail may warrant the additional costs of compilation, due to the heterogeneous nature of economic sectors in terms of their environmental characteristics.     

Improving the Sustainable Development of Firms: The Role of Employees

Stakeholders have been found to be an important driver of organizations' sustainable development. In particular, customers, governments and non‐governmental organizations push firms towards sustainability. But to what extent is sustainability really and deeply embedded within an organization's structures and processes? And what is the role of an important, but frequently neglected, stakeholder group for successful sustainability implementation: employees? The objective of this research is to better understand the impact that organizational change for sustainability has on firm performance. Also, this study seeks to understand how the consideration of employees into the process of organizational change for sustainability moderates the organizational change and performance relationship. Using data from 92 German companies from the manufacturing and services sector, the study finds that the structural implementation of sustainability is positively related to firm performance and that employee integration moderates this relationship to some extent.

A multiregional planning and forecasting model with special regard to the public sector

Despite the magnitude of the public sector and its rapid growth most multiregional economic models are lacking public sector content. The present paper aims at incorporating some of the roles of the public sector in the regional development. It is done within the framework of a multiregional optimization model for the allocation of private and public investment, production, employment (and population) over economic sectors and regions. By choosing appropriate objective functions, the model may be used for either planning or forecasting purposes. In the model the focus is on the public sector as a service and provision body and as a provider of public infrastructure. Its role as an agent for transfer payments is not stressed. The capacities of the model are illustrated by means of an example concerning Swedish regional development 1977–1983.     

Robotic Process Automation in purchasing and supply management: A multiple case study on potentials,barriers, and implementation

Robotic Process Automation (RPA) has received growing attention within the digital transformation as this cutting-edge technology automates human behavior and promises high potentials. However, the adoption in purchasing and supply management (PSM) is still in its infancy and has hardly been explored, particularly in the public sector. Based on a multiple case study including 19 organizations of the public and private sector, this paper narrows that gap and presents comprehensive insights into potentials, barriers, suitable processes, and best practices and components for RPA implementation. The findings indicate that adoption depends on the organizations’ digital procurement readiness and maturity. Application areas of RPA enlarge with increasing experience and range from transactional and operative tasks within the procure-to-pay process to more strategic use cases in sourcing and supply relationship management. Potentials mainly comprise employee reliefs, cost savings, and increased operational efficiency and quality. We uncover multiple technical, organizational, and environmental barriers related to IT infrastructure and human resources, internal communication, financial resources, top management support, organizational structures, supplier-related issues, and government regulations. Furthermore, our study indicates several differences between the private and public sectors for RPA implementation. We outline implications for the emerging research on RPA and pivotal directions for organizational practice.
