Power is a central element and salient research topic within supply chain management, and it is also regarded as a key attribute influencing innovation in the supply chain. However, there are still disputes about the consequences of power and whether it should be used. Given this, we examine the relationship between power and innovation, and attempt to explore how to use power to improve innovation performance. In order to better understand power and its influence, we distinguish between possessed and realized power. Using the panel data collected in the Chinese high-technology companies (2014–2018) and controlling for contingencies, we found that there are positive relationships between possessed power and exploitation, exploration, especially the collaborative innovation of them, and these relationships are negatively moderated by financial slack. Surprisingly, we find inverted U-shaped relationships between realized power and exploitative, explorative and collaborative innovation. That is, the excessive use of power begins to show diminishing innovation returns. These findings offer new insights into power and its use in supply chain relationships by distinguishing possessed and realized power, and enrich the literature on supply chain management and innovation.

Extant agency theory addresses dyads consisting of a principal and an agent. It informs us about how to overcome agency problems in the buyer-supplier relationship. In this conceptual paper, we propose a theoretical argument that if we expand the boundary conditions from dyads to triads, we find new solutions to dealing with agency problems. To the buyer-supplier dyad, we add the supplier’s supplier, the buyer’s other supplier, the supplier’s other customer, and the buyer’s customer. As such, we consider four types of triads in supply chains and propose that the buyer as the principal could reframe agency problems with the focal supplier by moving to one of these triads. In particular, we investigate alternative mechanisms that may reduce the level of goal incongruence, information asymmetry, and power asymmetry in the buyer-supplier relationship. Our conceptualization suggests that supply managers should look outside the buyer-supplier dyad for additional opportunities to resolve agency problems.

Purchasing and supply management (PSM) has faced unprecedented disruption over the past two years due to COVID-19 pandemic, input shortages, extended supplier lead times, record international transportation costs, and commodity price increases. Studying such phenomena is often best completed using archival data, such as data from government agencies or international organizations. This manuscript emphasizes how leveraging archival data often necessitates an iterative research process whereby researchers must first familiarize themselves with the data to ensure their scientific hypotheses can be appropriately tested. We further provide recommendations regarding how researchers should formulate generalized linear models (GLMs) to test theoretical predictions. Our approach emphasizes mapping scientific hypotheses to statistical hypotheses, as opposed to centering on issues of omitted variable bias (OVB). An illustrative example is provided where Census Bureau trade data are compiled to test whether the insurance and freight costs for waterborne containerized imports from Asian nations that enter through West Coast ports have risen more than the same products imported through East Coast ports. The research suggests the need to reorient how GLMs are formulated to better ensure researchers structure them to appropriately test their theory, in contrast to the current zeitgeist that overly emphasizes OVB.

A variety of contract typologies that exist in the literature are helpful in the exploration of different approaches in contractual relations, but only when measured with the right instruments. Although Transaction Cost Economics (TCE) has a distinct, high-level, and abstract typology for contracts, it still lacks a measurement scale. In this paper, a measurement scale for the TCE contract typology (classical, neo-classical, and relational contracts) was developed and validated, using systems thinking approach and experimental design to contribute to the empirical tests of TCE within the contracting realm. First, the antecedents of contract selection within the TCE literature were analyzed using the systemigram technique to visualize and parse out complex relationships that lead to contract selection. The analysis of the TCE Systemigram helped the development of the scale and revealed the need to revisit the risk neutrality assumption embedded in TCE. Second, a measurement scale for the TCE contract typology (classical, neo-classical, and relational contracts) was developed adhering to the original texts of seminal papers and reviews from the TCE literature. Third, the 14-item measurement scale was validated using a series of three vignette-based experimental studies.

Key message

This research explores the antecedents of the TCE contract typology and develops a measurement scale for essential characteristics of classical, neo-classical, and relational contracts, as defined in TCE, using systems thinking approach and a novel vignette-based experimental design.

Reshoring has gained a lot of attention recently by academics and practitioners alike, and is promising to become even more relevant in the aftermath of the COVID-19 pandemic. Building on earlier research on the effects of reshoring announcements on the short-term market value of the firm, this work employs an event-study methodology and aims to understand under which circumstances the market perceives reshoring as potentially more (or less) value-creating. The analysis of a sample of 64 reshoring instances from 2005 to 2019, announced by 54 firms from eight developed economies, suggests that investors are more confident in the firm's future cash-flow potential when: a) it invests in productive activities at home, instead of overseas, i.e. ‘kept-from-offshoring’ (as opposed to actual relocations of activities, i.e. ‘back-reshoring’); b) the reshoring instance is communicated as a ‘plan’ (rather than a fixed ‘decision’); c) no state- or government-induced financial incentives are involved; d) the motivations are primarily ‘cost-efficiency seeking’ (rather than ‘customer perceived value seeking’).

This paper analyses the uptake of a voluntary green public procurement policy in Sweden. The policy, decided in 2006, stated a national goal for the public sector to increase its share of organic food purchases to 25% by 2010. The overall purpose was to increase organic farming. Municipalities, which are highly independent authorities with self-determination, were encouraged to formulate own political goals. Based on survey data on organic food purchases for the period 2003–2016, supplemented with data on municipality characteristics, we analyse the determinants of the local uptake of the national policy, accounting for potential selection bias. The main finding is that local political goals are set and that these have in turn, a significant and positive effect on the share of organic food purchases. This suggests that there is an uptake of the voluntary policy. Also, we find that the increase in expenditures per capita devoted to organic food is quite substantial following the adoption of a local policy.

Bringing innovative products to markets is essential for companies, especially in competitive environments. One of the driving forces for successful new product development (NPD) is the inclusion of the functions that form part of the process such as purchasing and supply management (PSM). While extensive research has been conducted on the role of procurement in promoting innovation, insufficient research on the future of the PSM function in NPD has been conducted. This study addresses this gap, considering increasing digitalization and its effect on the future PSM function managing purchasing and innovation. To explore the future of PSM in NPD, a Delphi survey with 91 experts from industry, academia, and politics or associations was performed. The results reveal that digitalization will influence the PSM function in NPD across different time horizons and forms depending on the subject area. While in many areas, an interplay between digital technologies and human PSM professionals is expected, in certain domains the PSM function is likely to lose added value compared to digital technologies. Furthermore, digitalization is expected to be a potential enabler of a stronger key innovation role for PSM in NPD but to also introduce new requirements such as data science capabilities.

This paper introduces the special topic forum (STF) on purchasing and innovation. Presenting the findings from a systematic literature review, we take stock of the current state of the field, delineating themes, theories and methods, and identifying key trends over time. Our study shows a take-off in research on purchasing and innovation during the last decade. This has predominantly focused on private sector manufacturing firms although a recent expansion into public sector research is evident. Large-scale surveys and case studies are still the dominant research methods where the unit of analysis is typically the ‘firm’ or ‘project’. The findings also show how in the past the field was driven by questions on how purchasing can facilitate different types of innovation projects, seeking to derive practical implications, and rarely making explicit statements regarding theories applied; this still characterises much of the research but we find an increasing focus on theory development. We also see a shift in the type of technological innovation being investigated: past studies tended to focus on the role of purchasing in new product development (NPD) projects, which reflected a relatively low degree of technological uncertainty, but we see a trend towards innovation projects facing technological uncertainty. Research shows how this requires new ways of sourcing innovations and therefore new ways for purchasing to facilitate innovation sourcing. On the basis of the review, we offer our guidance for future research avenues to 1) carry out more research on procurement of innovation in the public sector; 2) consider new theories and research methods, and 3) go beyond firm-level or dyadic analysis to research networks and ecosystems. We conclude by introducing the papers in the STF.
