Public procurement of goods and services accounts for a significant portion of government budgets. Among contracts awarded annually by the United States federal government, a disproportionate amount of total spend is given to a relatively small number of contractor firms, many of whom have committed government contract misconduct in the past. We leverage insights from the contracting literature and organizational learning theory to understand the relationship between past contract misconduct and the likelihood of a subsequent contract misconduct violation, along with contextual factors that could influence this relationship. Using composite misconduct data captured from a longitudinal dataset of United States Department of Justice (DOJ) public procurement, a probit regression analysis reveals that firms with a history of government contract misconduct violations are increasingly likely to commit a subsequent violation, yet this relationship is not linear. Further empirical analysis reveals characteristics of contracting firms and purchasing relationships which moderate this phenomenon. Our findings contribute to the literature by providing empirical support regarding the relationship between past and future contract misconduct violations within public procurement relationships. We also offer several implications to practitioners and policymakers to support the identification and management of repeat contract misconduct violators.

In 2018, the United States imposed numerous tariffs with the stated intent of protecting U.S. firms from international competitors. These tariffs have had a substantial impact on supply chains which were not well understood. While tariffs can provide some protection to certain industries, they can also create inefficiencies for the industries they were designed to protect, as well as for their supply chain partners. We analyze the impacts of the tariffs imposed by the United States in 2018, on the industries they were intended to protect (steel, semiconductors, agricultural equipment, and chemicals industries) as well as on their suppliers and customers. We perform an event study to analyze the effects of four discrete suites of tariffs on the firm value of 691 publicly traded U.S. firms. We utilize resource dependence theory (RDT) to better understand the net impact of tariffs on protected industries and their supply chains. The results demonstrate that the implementation of the 2018 tariffs had an overall negative impact on firm value, leading to a decrease in the value of domestic producers within the protected industries and mixed financial effects on firms in their supplier and customer industries. These findings demonstrate the ripple effect of unintended consequences that tariffs can lead to throughout supply chains, motivating further theoretical development and informing trade policy.

With the increasing level of supply chain complexity, the mechanisms of emergence and control have become essential for achieving superior performance. To operationalize the relationships between the two mechanisms, we develop the dimensions of balance emergence-control (BEC) and combined emergence-control (CEC). While BEC highlights the need to match two mechanisms that are substitutes, CEC treats emergence and control rather as complements that reinforce one another. Additionally, we also develop the construct of supply chain ambidexterity as a conglomerate of exploitation and exploration practices performed within service triads. In this study, we investigate the effects of supply chain ambidexterity on emergence and control, and their resulting effects on triadic relational performance.

To develop the research model and test hypotheses, hypothetic-deductive logic was employed to underpin the quantitative survey-based methodology. The data for the analysis was derived from 350 service triads operating in Europe. To ensure the robustness of the results, Confirmatory Factor Analysis was carried out, followed by hierarchical regression analysis and path analysis. The findings show that while supply chain ambidexterity has a positive effect on emergence, it has a negative effect on control. The results also demonstrate that when applied independently, balance emergence-control and combined emergence-control have a respective positive and negative effect on triadic relational performance. Interestingly however, when applied collectively, balance emergence-control and combined emergence-control demonstrate a positive effect on triadic relational performance.

In this paper, we state and debate the use and usefulness of text similarity and network analytics using natural language processing for our field. While previous reviews of Purchasing and Supply Management have relied on manual coding and classification, the large scale and variety of the field calls for new approaches. In this Notes and Debates article, we therefore review different approaches from bibliometric and scientometric studies to explore literature using (semi)automated approaches. We exemplify one approach, leveraging text similarity and network visualization, to complement earlier analysis. Along the way, we discuss the researcher’s role at critical vantage points in reviews that are augmented by natural language processing. We compare and contrast the results of this exploration to previous manual reviews and sketch opportunities and provide recommendations for future use.

A firm's CSR controversies can affect not only the firm itself but also its supply chain partners. However, existing studies have predominantly focused on the influence of a firm's own CSR controversies; the spillover effect along supply chains has received insufficient attention. This study examines the impact of suppliers' CSR controversies on buyers' market value, as well as the moderating role of buyers' social capital. Using data from 462 buyer-supplier dyads of Chinese listed firms from 2008 to 2019, we find that suppliers' CSR controversies are significantly negatively related to buyers' market value, and that environmental controversies have a stronger negative effect than social controversies. This negative association can be alleviated by buyers' social capital in the forms of political, business, and financial capital. Our study has significant implications for both research and practice in the increasingly important domain of CSR management in supply chains.
