While existing studies regarding organizational vacillation theory have focused on examining how vacillation may lead to ambidexterity, few studies have focused on how vacillation itself happens and whether it happens symmetrically or not. To bridge this research gap, this paper analyzed organizational vacillation over time with two canonical cases while examining patterns of organizational structure over time. Unlike previous studies that only revealed the existence of vacillation between centralization and decentralization, this study revealed that vacillation is observed with an asymmetric ratio of duration in the business world by finding that each company within the same industry spends a greater portion of time in a certain organizational structure than the other. By analyzing these changes throughout the business history, this study found that organizational vacillation happens asymmetrically while alternatively shifting between centralization and decentralization. Based on the case study result, this study draws propositions that can enable future researchers to advance theoretical and empirical understanding toward asymmetric vacillation.

This study examines how NoBrand has faced legal regulations in Korea, and NoBrand's transition to the franchise system to respond to regulatory changes (examined with a case analysis). In 2015, Emart, a Korean retail giant, launched its private brand (PB), NoBrand, to address stagnant sales. With advantages in price and quality due to supply chain management (SCM), NoBrand not only established a successful foothold, but also gained success in the market. Despite the rapid growth of NoBrand, it has faced government regulations that restrict its operations. To respond to these regulations, NoBrand changed its direct operating system to a franchise system that allows an individual owner to run his or her own NoBrand store. However, the transition triggered conflicts with both local stakeholders and other branches of its parent firm, Emart. By analyzing these conflicts, this study finds that Korean retail policy did not effectively protect small business owners as primarily aimed.

AbstractResearch Question/IssueThis paper examines R&D investment decisions in firms under a pyramidal ownership structure in the context of South Korea.Research Findings/InsightsUsing the Monopoly Regulation and Fair Trade Act, which places limits on group affiliates' equity investments, we provide new evidence that controlling owners tend to increase long‐term R&D expenditures more in firms that are largely subject to the equity investment regulation in South Korea. Moreover, this result is more significant for firms for which the owners have low cash‐flow rights, firms located in the lower layers of the pyramid, and firms that hold less equity shares than do other group affiliates.Theoretical/Academic ImplicationsThis study contributes to the literature that focuses on R&D investment decisions by providing empirical support regarding how firms' relative status within their business group influences the firms' R&D investment decisions in South Korea.Practitioner/Policy ImplicationsThis study provides important insight into the positive policy implications of the equity investment regulation on R&D investments for Korean business groups.

This study investigates incumbent firm responses to disruptive innovation in the rapidly evolving South Korean retail industry. The study explores the factors behind an incumbent firm's decision-making processes when responding to disruptive innovation and examines the reasons behind varied incumbent responses. It investigates the agents that influence a firm's decision by conducting the qualitative case study of a South Korean retail giant, Lotte. By collecting archival data from various sources, this paper was able to analyze different interviews and statements of the chief executive officer (CEO). From the analysis, it was determined that the firm's overall actions were aligned with the CEO's assertions. Thus, this paper asserts that Lotte's response to disruptive innovation was directly influenced by the CEO's attention. The results of this study further add to the discourse of disruptive innovation by highlighting the importance of CEO discretion in deciding a firm's direction and by further emphasizing the relationship between managerial leadership and innovation.

This study examines the crucial role of chief executive officers (CEOs) in post-acquisition integration, focusing on Chegg, a prominent ed-tech company in a rapidly evolving industry. Analyzing CEO actions post-acquisition through interviews and metrics, we find that a three-year CEO retention period significantly contributes to successful integration at Chegg. This research emphasizes the importance of understanding ideal CEO retention and their strategic actions, offering insights for more successful post-acquisition integration and long-term economic benefits.

Several studies have shown that some genetic variants associated with COPD have been identified in genome-wide association study (GWAS), especially in patients with moderate to severe COPD; genetic susceptibility for airflow limitation in the early COPD phase has not been widely studied.Objective: We investigated the genetic variants in early COPD.Methods: The present study analyzed Gene-environment interaction and phenotype (GENIE) cohort that included participants who received health screening examination. The association between single nucleotide polymorphism (SNP) and susceptibility to early COPD (FEV1 predicted ≥ 50% and FEV1/FVC < 0.7) was tested.Results: A total of 130 patients with early COPD and 3478 controls (1700 ever smokers and 1778 never smokers) were recruited. When compared with the total controls, certain SNPs (rs2818103, rs875033, rs9354627, rs34552148) on chromosome 6 were included at the top of our list (p= 5.6 × 10– 7 ∼ 9.6 × 10– 6) although they did not reach genome-wide significance. When compared with the never smoker controls, two SNPs (rs2857210, rs2621419) of the HLA-DQB2 gene class were persistently associated with susceptibility to early COPD.Conclusion: Certain SNPs located on chromosome 6 or the HLA-DQB2 gene were the top-scoring SNPs for the association with susceptibility to early COPD in the Korean GENIE cohort.Keywords: early chronic obstructive pulmonary disease, genome-wide association study, single nucleotide polymorphism, SNP, HLA-DQ gene
