This paper examines the adjustments firms make to the composition of their portfolios of technology-sourcing vehicles (i.e., alliance, acquisition, or go-it-alone) in response to poor innovative performance. We advance a behavioral perspective on the make/buy/ally question, suggesting that differences in financial slack will generate different portfolio decisions. Specifically, we posit that firms with greater levels of financial slack are more likely to respond to poor innovative performance by opting for (1) greater vehicle diversification, and (2) new sourcing vehicles, while firms with lessfinancial slack will respond by (1) downscoping their portfolio of sourcing vehicles, and (2) reverting to more familiar vehicles. We find support for our predictions using extensive data from the population of U.S. public pharmaceutical firms from 1992 to 2006.

Purpose – The purpose of this paper is to determine the state-of-the-art in socially responsible sourcing (SRS) research, leading to an agenda for further work; and to evaluate the use of theory in this context. SRS is defined as the upstream social issues within the sustainability literature, where social issues include human rights, community development and ethical issues but exclude environmental concerns. Design/methodology/approach – A systematic literature review of 157 papers that include SRS published in ABS listed journals. The papers have been analysed according to their research content, with a particular focus on the use of pre-existing theories. Findings – Key findings for researchers and managers alike include an analytical discussion of strategies developed to date to embed SRS in an organisation; and key research gaps include a particular need to consider the supplier perspective in developing countries. In terms of the use of theory, a typology is proposed, which (in ascending order of effectiveness) is as follows: theory dressing, theory matching, theory suggesting/explaining and theory expansion. Research limitations/implications – The review is limited to papers published in the ABS list; and the analysis of the use of theory is limited to the SRS literature. The findings suggest that insightful papers can be written without any use of theory but that as a field develops, a greater depth of application of theory is needed to aid understanding. Originality/value – This is the only review that focuses exclusively on social issues SRS, excluding environmental issues, thus allowing for a greater depth of discussion on social issues; and is unique in its detailed critical analysis of the use of theory.

A Class-AB LDO capable of sinking/sourcing current from/to the load is presented. Unlike conventional LDO structures, the input reference voltage of this circuit is adjustable and has a wide adjustment range. The circuit has been demonstrated in a 0.35 um BCD process at a 3.3 V supply voltage. Its low-frequency sourcing 10 mA current, sinking 10 mA current and no-load PSRR are -80.3 dB, -106.1 dB, and -83.4 dB, respectively. The voltage undershoot is 69 mV when the output changes from sinking 10 mA to sourcing 10 mA in 10 us, and the overshoot is 64 mV for the opposite process. The minimum phase margin is 50 degrees at 0.1-10 mA load current. The area of the entire LDO circuit is 0.28 mm 2 , including the protection circuit.

The purpose of this study is to present a rigorous, focused review on how this field of ethical sourcing research has grown and evolved over the decades, providing implications for future research. We combine two research methodologies in this study: a systematic literature review and a citation network analysis. The former is used as a scientific tool to select the most relevant ethical sourcing articles, while the latter is then applied as a research technique to analyse these selected articles. Such a combined approach allows for a rigorous investigation into this field of research in a more scientific and objective way. Based on this approach, we identify (1) distinctive features of ethical sourcing studies such as growth trends and content issues; (2) important articles that have played a significant role in developing this field; (3) evolutionary paths that show how its knowledge has been created and transferred; (4) emerging trends that have received growing attention in the recent literature; (5) main research areas that underlie the entire ethical sourcing studies; and (6) major implications that need to be pursued in future research. The results of this study provide not only the current status of the literature but also the patterns of evolution in this field of research, thus contributing to the existing literature.

Companies that source from emerging economies often face supplier responsibility risks , namely, financial and reputational burdens that the companies have to bear when their suppliers’ engagement in noncomplying labor and environmental practices becomes public. To mitigate such risks, companies can invest in screening mechanisms and design incentive schemes in sourcing contracts. Common mitigation instruments include supplier certification, process audits, and contingency payments. The interactions of these instruments are often not well understood. We first note that the effectiveness of any mitigation instrument depends on how it changes the economic trade-offs faced by a supplier in compliance to social and environmental standard, and hence we develop a model that explicitly captures such trade-offs. As a result, our model endogenizes the supplier’s noncompliance probability and connects it with various factors, including the supplier’s intrinsic ethical level that is unobservable to the buyer. We then study the buyer’s optimal contracting problem under different mitigation instruments. We find that although the process audit and contingency payment instruments can directly lower supplier responsibility risk, they, acting alone, are not as effective as the supplier certification instrument in screening suppliers with different ethical levels. Nevertheless, these instruments are all complementary to each other; when used jointly, they make supplier screening more effective and result in lower sourcing cost. These findings provide explanations for some of the observed practices used in industry to mitigate supplier responsibility risks.

Purpose The aim of this paper is to enhance understanding of the use of sourcing teams (STs) by organisations in their procurement and supply chain management. The paper achieves this by exploring, within the context of the supply chain directorate of a global aerospace manufacturing company (GAMC), both the relationship between sourcing teamwork effectiveness (TE) and sourcing task-work effectiveness (TA) and the relationship between individual team member knowledge, skills and abilities (KSAs) and TE. Design/methodology/approach The authors develop a theoretical model positing positive links between both KSAs and TE and TE and TA. The model is empirically validated using partial least squares structural equation modelling in a survey of 108 ST members from a GAMC. Findings The authors identify that, within GAMC, four of five KSAs drive TE and further discover the direct effects of TE on improved TA. Additionally, the authors observe within GAMC the indirect effects of KSAs on TA cascading through TE. Research limitations/implications Limitations include the use of a single firm and self-report measures for data collection. In spite of this, the paper has numerous research implications. Previous research on STs has combined factors related to TE and TA. In this paper, TE and TA were disaggregated, and the relationships between them were explored. The relationships were found to be positive within GAMC, a finding that strengthens the evidence base supporting the use of STs by organisations in their procurement and supply chain management. In addition, the paper also strengthened the evidence base regarding the importance of KSAs to TE, which complements existing research highlighting the importance of team-level factors and individual technical attributes. Practical implications The findings from GAMC suggest that executives/managers should take an individual as well as a team-level perspective when developing STs and should consider KSAs as well as technical knowledge when judging individuals’ suitability for inclusion within an ST. There are established KSA tests in the literature that could be used by managers for this task. The findings also inform executives/managers that TE matters for TA and needs attention and investment, especially where sourcing tasks concern high-value areas and/or critical incidents within supply chains. Originality/value To the best of the authors’ knowledge, this is the first paper to explore the relationship between TE and TA. Establishing that this relationship is a positive one provides critically important evidence regarding the efficacy of STs, which are widely used within procurement and supply chain management. It is also a rare study looking at TE from the perspective of individual team member KSAs, with further positive relationships revealed. Both findings enhance what is a very limited literature on a widely used practice within procurement and supply chain management.

Facing increased pressure to use renewable energy and achieve energy efficiency, organisations have the complex task of sourcing energy services from energy providers in business-to-business (B2B) contexts. We aimed to explore how customers in such contexts approach the sourcing of energy services. Our theoretical and empirical approach linked energy as a service offering and customer–provider interfaces used in sourcing energy services to elucidate the practices adopted in such sourcing by customers in B2B contexts. To that end, we employed a qualitative research approach using the Gioia methodology and conducted 18 semi-structured interviews with representatives of 18 firms in the B2B market for energy services in Sweden. Our results revealed two central categories of how energy services are sourced: basic and advanced. The theorising of those categories as forms of direct and indirect energy efficiency, combined with four types of energy services—information-, analysis-, improvement- and contract-oriented services, which include a description of energy services exchanged, where the customer uses the energy service, the customer’s sourcing practices and characteristics of sourcing practices—provides important contributions to the literature on energy services. In turn, we propose a four-part typology of interfaces used by providers and customers of energy services that considers the type of services sourced.

Purpose This paper aims to set out the development, based on the extant literature, an integrated conceptual framework for the emergent field of sustainable global sourcing (GS) that synthesizes its antecedents, GS practices and sustainable performance. Design/methodology/approach Conceptual theory building combined with content analysis is used to develop a framework and propositions representing a middle-range theory of sustainable GS. A literature review of the 89 most influential papers is followed by a further discussion based on the resource orchestration perspective (ROP) to advance an integrated conceptual framework. Findings Three main themes are identified from the literature as antecedents, GS practices and sustainable performance, with each theme being detailed in a variety of constructs. Based on the ROP, the relationships between these constructs are revealed, and therefore, an integrated conceptual framework is advanced via three sets of propositions in recourse orchestration breadth, recourse orchestration depth and resource orchestration evolution, respectively. Eight directions for future research are further proposed. Originality/value First, this study provides a comprehensive framework for future study in the emergent field of sustainable GS. Second, the authors contribute to theory development by proposing a ROP to explore the GS practices towards sustainability. Third, the future research directions we proposed can benefit scholars interested in the overlapping areas of GS and sustainability.

We analyze the sourcing decision of a buyer choosing between two supplier types: responsible suppliers are costly but adhere to strict social and environmental responsibility standards, whereas risky suppliers are less expensive but may experience responsibility violations. A segment of the consumer population, called socially conscious, is willing to pay a higher price for a product sourced from a responsible supplier and may not purchase in the event of a responsibility violation from a risky supplier. We identify four possible sourcing strategies that a buyer might employ: low cost sourcing (sourcing from the risky supplier), dual sourcing, responsible niche sourcing (sourcing from a responsible supplier and selling only to socially conscious consumers), and responsible mass market sourcing (sourcing responsibly and selling to all consumers). We determine when each strategy is optimal and show that efforts to improve supply chain responsibility that focus on consumers (by increasing their willingness to pay for responsibility or increasing the number of consumers that are socially conscious) or increasing supply chain transparency may lead to unintended consequences, such as an increase in risky sourcing. Efforts that focus on enforcement and penalizing the buyer, however, never backfire and always lead to more responsible sourcing and less risky sourcing.

Recent work has shown that a firm’s plural sourcing strategy, which determines how much it chooses to make versus how much it chooses to buy, requires consideration of the complementarities and constraints that affect the differential advantages of making and buying. Elaborating on this perspective, we theorize how (mis)fit between a firm’s plural sourcing strategy of simultaneously making and buying and its development of information technology (IT) enabled interfirm and intrafirm process integration capabilities influences firm performance in deregulated markets. We position our theory development and empirical tests in the context of the power-generation segment of the U.S. electric utility industry (EUI), an asset-intensive industry that has been deregulated to promote the separation of key value chain activities (i.e., generation, transmission, and distribution) and the development of wholesale energy markets. We draw on the transaction cost economics, coordination costs, and IT capabilities perspectives to theorize that a firm achieves fit (realizing performance benefits) by increasing market sourcing intensity (MSI)—or, how much it buys relative to how much it makes—and developing IT-enabled interfirm process integration capability for external coordination with the market, or misfit (realizing performance penalties) by increasing MSI and developing IT-enabled intrafirm process integration capability for coordinating internal production. We collated data from archival sources for 342 utility firms in the power-generation segment to construct a panel dataset for the period 1994–2004 on (1) firms’ MSI from wholesale electricity markets, (2) firms’ IT investment decisions to develop interfirm and intrafirm process integration capabilities, (3) measures of firm performance, and (4) several control variables related to exogenous shocks (i.e., regulatory change, oil crisis), region of operation, and firm-level factors. Our results suggest that fit between MSI and the development of IT-enabled interfirm process integration capability improves firm profitability, assessed by return on assets, and misfit between MSI and the development of IT-enabled intrafirm process integration capability extracts penalties in firm profitability. We also find evidence that fit between MSI and the development of IT-enabled interfirm process integration capability improves market valuation, assessed by Tobin’s Q, and asset turnover, assessed by operating revenue/total assets. We discuss the implications of our findings for the development of IT capabilities to accompany a firm’s plural sourcing strategy and the literature on IT business value.
