This paper analyzes trader‘s strategic behavior in the KOSPI200 index options market. Using intraday data for various at-the-money options, we obtain the following results : (1) The frequency of trades is a better market statistic than trade size for option price volatility. This may result from the hedging behavior of large traders. This also suggests that the informed traders utilize their informational advantage gradually. (2) The effect of the duration of previous intervals on the expected duration of current intervals is persistent. (3) In the modified ACD model, the standardized distribution of duration is not exponential; rather, it is Weibull with r < 1. (4) There is no specific diurnal pattern of the duration of the duration of the options market. (5) we find a clear maturity effect.

The maritime freight transportation industry has played an important role in the Korean economy. The Korean maritime freight transportation industry is faced with a period of transforming it competitively and efficiently in this global age. This paper, therefore, aims to identify the impact of the maritime freight transportation industry in the Korean national economy. Hence, this paper provides policy-makers with accessible and reliable information regarding the role of the Korean maritime freight transportation industry. This study employs input-output (I-O) analysis to examine the role of the maritime freight transportation industry in the national economy for the period 1995-2003, with specific application to Korea. This study pays particular attention to the maritime freight transportation industry by taking the industry as exogenous variable and then investigates its economic impacts. We identify inter-industry linkage effects in 20 sectors, production-inducing effects, added value-inducing effects, and supply-shortage effects of the maritime freight transportation industry.

This study aims to assess the effect of job insecurity, customer incivility and work–life imbalance on Lebanese bank employee workplace well-being (EWW), while investigating the moderating role that positive and negative affect might have.

Quantitative data was collected from 202 respondents and analyzed using structural equation modeling system through IBM SPSS and AMOS.

Results revealed that each of the independent variables has a negative, statistically significant effect on Lebanese bank EWW. The positive affect and the negative one are shown to have a moderating effect that lessens and boosts, respectively, these negative effects.

The study adds to the literature on EWW while highlighting the high-power distance and collectivist society that the research took place in.

Limitations include the sample size that was hoped to be larger, in addition to the self-reporting issue and what it entails in the data collection process.

The study has many practical implications, including the validation of a questionnaire in a developing Arab country, hence providing a reliable tool for researchers. HR specialists should lean toward applicants with positive affect, ensuring that their workplace is occupied by members with enhanced resilience. Furthermore, employers should support their employees’ professional growth, thus, boosting their employability during turmoil and consequently making them less vulnerable in times of economic recession.

The study’s unique context, depicted in the harsh economic and financial crisis, makes the findings on EWW of a high value.

This paper aims to present the trajectory of corporate family-friendly policies (FFPs) in South Korea, as it evolved from an emerging economy to a developed country. The adoption of FFPs by South Korean corporations since the 1960s has been shaped by a dynamic interplay of cultural, political, economic, legal, social and organizational forces. The authors use the example of South Korea to propose a three-stage conceptual model for the adoption of FFPs in emerging economies.

Adopting the institution-based view, the authors explore the theoretical framework for implementing FFPs in corporations in emerging economies. This paper uses South Korea as a case study, reviewing its economic and corporate transitions from the early 1960s through 2023. The authors analyze cultural and macro-level forces, including political, economic, legal and social contexts to understand their impact on the adoption of FFPs.

The adoption of FFPs in South Korea encompassed three historical stages – embryonic, stagnant and leaping. The embryonic stage brought the birth of social interest in a worker-friendly environment, alongside rapid economic growth. In the stagnant stage, economic growth plateaued, resulting in stalled discussions of FFPs. In the leaping stage, economic recovery raised employee expectations, societal demands for FFPs to address ultralow fertility rates intensified and corporations adopted FFPs. All three stages are apparent in an emerging economy that is undergoing rapid growth and industrialization.

There has been scant investigation into the historical adoption of FFPs by emerging economies. The findings enrich the international literature by proposing a developmental model of the adoption of FFPs in emerging economies.

This paper investigates a retrospective on the Journal of Derivatives and Quantitative Studies (JDQS) on its 30th anniversary based on bibliometric. JDQSs yearly publications, citations, impact factors, and centrality indices grew up in early 2010s, and diminished in 2020. Keyword network analysis reveals the JDQS's main keywords including behavioral finance, implied volatility, information asymmetry, price discovery, KOSPI200 futures, volatility, and KOSPI200 options. Citations of JDQS articles are mainly driven by article age, demeaned age squared, conference, nonacademic authors and language. In comparison between number of views and downloads for JDQS articles, we find that recent changes in publisher and editorial and publishing policies have increased visibility of JDQS.

This paper reconsiders the approaches to measuring Confucian values, and tests their association with workforce performance. The purpose of this paper is to examine how such values and performances are prioritized across three East Asian societies, but more importantly, identifies how variations across societies might result from the way in which Confucianism has been transformed/appropriated differently across history.

A Best-Worst experimental design is used to measure three aspects of Confucianism (relational, pedagogical, and transformative), and three aspects of workforce performance (mindset, organization, and process) to capture the trade-offs by respondents from three East Asian societies: China (n=274), Taiwan (n=264), and South Korea (n=254). The study employs analysis of variance with post-hoc tests to examine differences between societies. A hierarchical cluster analysis using Ward’s method is utilized to identify clusters based on similarities within the data. And last, multiple regression analysis is applied to determine the explanatory power of Confucian values on workforce performance.

Findings confirm the prioritization of three aspects of Confucianism (relational, pedagogical, and transformative) to differ between Mainland Chinese, Taiwan Chinese, and Korean respondents – producing five distinct clusters based on similarities across three societies. Overall, between 7 and 27 percent of the variance in workforce performance could be explained by the Confucian values included in this study.

This study highlights the “different shades of Confucianism” across East Asian societies, which we coin as Confucian Origin, Preservation, and Pragmatism, and demonstrates the need to take a multifaceted perspective in the measurement of Confucian culture. The study provides empirical support for the link between Confucianism and performance at the micro-level, as originally proposed by Baumann and Winzar (2017), and identifies specific antecedents of behavior for research moving forward.

The purpose of this study is to consolidate the state of research in mobile commerce (m-commerce) technology adoption from 2008 to 2017. This study not only reviews the evolution of m-commerce literature but also highlights the significant contribution of authors and their productive collaborations in the development of this area.

A total of 184 peer-reviewed articles focusing on m-commerce adoption were obtained after applying search criteria on Scopus database. After using inclusion and exclusion criteria to achieve the objective of this study, 86 journals were shortlisted. The study further discusses the dispersion of various m-commerce applications being explored in m-commerce literature. In addition, dominating technology adoption theories and the most used keywords have also been identified and discussed in this study.

This study indicates that technology acceptance model and unified theory of acceptance and use of technology are the most exploited technology adoption theories. Moreover, the dominating constructs in literature are perceived usefulness, ease of use social influence/social norm on behavior intention, attitude intention followed by performance expectancy, facilitating condition and effort expectancy influence on intention.

This study presents a detailed association rule mining and community analysis to show the association among constructs such as usefulness, ease of ease, social influence and intention as dominant group in this area. The study also identifies lesser explored constructs and indicates possible future research to validate and strengthen their understanding further.
