Using machine learning techniques, we construct the Bond News Sentiment Index (BNSI) from news articles on interest rates. Our analysis reveals that the BNSI has a hump-shaped relationship with bond risk premia in the following month. This result suggests that a stronger consensus of news articles on interest rate changes signals decreases in uncertainty, leading to lower bond risk premia. We propose a BNSI-based forecasting factor, which exhibits predictive power beyond existing factors both in- and out-of-sample 2026-12-01T00:00:00Z https://scholarworks.bwise.kr/hanyang/handle/2021.sw.hanyang/212942 Title: How insomnia among frontline service employees drives customer-directed counterproductive work behavior: Mediation of ego depletion and moderation of organizational health climate and health-oriented leadership Authors: Shin, Yuhyung; Hur, Won-Moo; Shin, Gyeongpyo Abstract: Frontline service employees (FSEs) often experience insomnia because of irregular work schedules, emotional labor, and demanding customer interactions. While previous research has mainly portrayed insomnia as a result of negative service encounters, little is known about whether insomnia itself leads to counterproductive service behavior. Using the conservation of resources theory, this study examined the effect of FSEs’ insomnia on customer-directed counterproductive work behavior (CD-CWB), with ego depletion as a mediating mechanism and organizational health climate (OHC) and health-oriented leadership (HoL) as contextual moderators. Three-wave survey data from 293 full-time FSEs in South Korea showed that insomnia was positively and indirectly related to CD-CWB through ego depletion. Moreover, OHC reduced the positive association between insomnia and ego depletion, making this association weaker when OHC was high. Although HoL did not exert a significant two-way moderating effect, the results indicated a significant three-way interaction: the relationship between insomnia and ego depletion was strongest when both OHC and HoL were low. These findings contribute to the service literature by extending sleep/resource-loss research to a frontline service deviance context and highlighting the buffering role of health-supportive organizational practices. 2026-08-01T00:00:00Z https://scholarworks.bwise.kr/hanyang/handle/2021.sw.hanyang/219057 Title: Enablers and inhibitors of word-of-mouth in ridesharing apps: a dual perspective on user involvement Authors: Park, Jungkun; Ye, Christine; Chen, Yuhsuan Abstract: To promote ridesharing as a sustainable transportation innovation, service providers and transport officials must understand the factors influencing users’ involvement intention. This study investigates the drivers of users’ word-of-mouth (WOM) intention toward ridesharing apps using a dual-factor framework (i.e., service quality, information quality, and system quality) and inhibitors (i.e., perceived risk and perceived uncertainty). It also examines the impact of WOM on situational and enduring involvement intentions, and the moderating role of customer citizenship behavior. Data were obtained through an online survey of 286 U.S.-based ridesharing app users. Results highlight service and information quality as key antecedents of WOM, and identify perceived uncertainty as a significant inhibitor. WOM was found to positively influence both forms of involvement intention. By integrating enablers, inhibitors, WOM, and customer citizenship behavior, this study advances understanding of user engagement with ridesharing apps and offers strategic insights for managers in both digital commerce and transportation service sectors. 2026-08-01T00:00:00Z https://scholarworks.bwise.kr/hanyang/handle/2021.sw.hanyang/219069 Title: 질적 연구 논문 투고 전략 Authors: 박태영 2026-07-03T00:00:00Z
