This study aims to investigate the influence of interpersonal justice, a sub-concept of interactional justice, on information accuracy and logistics performance in the pharmaceutical supply chain.

For this purpose, 600 pharmacies in Korea were surveyed through questionnaires distributed via mail and direct visits and 293 valid responses were used for statistical analysis.

According to the results, the perception of interpersonal justice between buyers and sellers showed a positive effect on information accuracy, which, in turn, had a positive effect on logistics performance within the supply chain. In contrast, interpersonal justice showed an insignificant effect on logistics performance.

This signifies that if buyers treat sellers with respect and politeness, the accuracy of the information provided by the seller will improve, which may ultimately have a positive effect on performance. In addition, ethical behavior by both parties ensures information accuracy in the supply chain, even though it does not directly affect performance.

In contrast to previous research, which has focused on distributive and procedural justice, the study investigates interpersonal justice and its effects on information accuracy and logistics performance in the pharmaceutical supply chain.

This study aims to empirically analyze how the quality of alternatives influences the commitment level in the relationships between companies in supply chains. It also studies how this ultimately influences the associated satisfaction level and logistics performance.

For this purpose, the authors adopted an extended investment model based on interdependence theory. The authors explored the relationships between logistics outsourcing partners based on the components of the investment model. To examine the correlations between variables, the authors surveyed workers in domestic supply chain–related departments and used a total of 300 valid questionnaires for statistical analysis. The hypotheses were verified through structural equation modeling using SPSS 18.0 and AMOS 18.0.

The quality of alternatives had a positive influence on the commitment level. Additionally, the commitment level had a positive influence on the satisfaction level but did not have a significant influence on logistics performance. Finally, the satisfaction level exhibited a proportional relationship with logistics performance.

First, this study examined the effects of the relationships between supply chain parties and psychological factors on logistics outsourcing. Second, this study applied the investment model to a logistics outsourcing-related topic. Finally, under the COVID-19 and the trade war, this study is significant as it shows that the existing commonly accepted hypotheses can be overturned.

This study differs from other studies in that it applied the investment model to a logistics outsourcing-related topic.

The purpose of this study is to verify whether the relationships between supply chain members can maximize supply chain efficiency by adopting an investment model that has been used in family psychology.

Information sharing was added as a link between commitment level and the independent variables of the investment model, and their effect on logistics performance in terms of supply chain operation was examined. The authors surveyed workers involved in supply chain-related work in Korea and collected 300 valid survey responses to verify the findings. The hypotheses were verified through structural equation model using SPSS 18.0 and AMOS 18.0.

This study academically revealed the impacts of intangible efficiency on performance. Satisfaction and investment size had a significant effect on information sharing, but not on the quality of alternatives. Information sharing had a positive effect on the commitment level. Finally, commitment level had a positive effect on logistics performance. Because the effects of satisfaction and investment size are proportional to the degree of information sharing, firms in a supply chain must consider their importance.

Owing to the complexity of today’s supply chains, the existing fragmentary method of analysis limits the evaluation of supply chain performance factors. Accordingly, based on an investment model that is rarely discussed in business administration, this study identified the link of antecedent variables in addition to direct variables that affect supply chain performance.

This study examines the relationship between trust, the investment model and logistics performance and the importance of commitment between companies in the supply chain. Furthermore, it analyzes satisfaction, quality of alternatives, investment size and commitment level, which are the constituent factors of the investment model, and reviews trust and logistics performance to ascertain their causal relationship.

The authors examined employees working in supply chain-related departments in Korean companies and further conducted an online survey for a month in January 2022 through the survey agency Entrust Survey, through which the authors distributed a total of 4,082 questionnaires and collected and used a total of 300 questionnaires for statistical analysis. The authors then validated the hypotheses using SPSS 18.0 and AMOS 18.0 using the structural equation modeling method.

The results showed that trust significantly and positively affects satisfaction levels in the relationship between companies in the supply chain. Trust can lower uncertainty in the transaction process between companies.

In this study, the investment model, which has been predominantly observed in the field of family psychology, was applied to business studies. In addition, the investment model was extended to enable its application to supply chain management research, thereby offering a distinctive research model from preceding studies.

The purpose of this paper is to investigate the mediating role of innovative behavior on the relationships between organizational structure, such as centralization, formalization, integration, and organizational innovation performance.

The authors collected data from 140 functional managers of manufacturing organizations in the Republic of Korea. The authors used structural equation modeling procedure to evaluate the validity of proposed hypotheses.

The results suggest that innovative behavior mediates the links among centralization, formalization, and organizational innovation performance. However, the findings indicate that innovative behavior does not mediate the relationship between integration and organizational innovation performance.

This work is the first to examine the mediating role of innovative behavior on the associations among centralization, integration, and organizational innovation performance.

The purpose of this paper is twofold: first, this work replicates the existing research by examining the links between job autonomy and work-related self-efficacy; and, second, it extends the literature by investigating the relationships between work-related self-efficacy and two forms of voice such as promotive and prohibitive and by measuring the mediating role of self-efficacy on the link between job autonomy and promotive and prohibitive voice.

The authors used a self-administered instrument to conduct a survey among 1,227 highly skilled employees. The researchers received a total of 904 questionnaires. After disregarding the non-usable questionnaires, the authors retained 813 questionnaires for the study. The overall response rate was 66 percent.

The results suggest that work-related self-efficacy has a significant relationship with prohibitive voice and mediates the link between job autonomy and prohibitive voice. Meanwhile, the findings of this study indicate that there is no significant association between work-related self-efficacy and promotive voice.

This work is the first to identify the association between work-related self-efficacy and prohibitive voice and the mediating role of work-related self-efficacy on the association between job autonomy and prohibitive voice.
