|
Trang Nguyen & Taha Chaiechi & Lynne Eagle & David Low |
DOI: 10.1108/JABES-01-2019-0009
Abstract
Purpose
Growth enterprise market (GEM) in Hong Kong is acknowledged as one of the world’s most successful examples of small and medium enterprise (SME) stock market. The purpose of this paper is to examine the evolving efficiency and dual long memory in the GEM. This paper also explores the joint impacts of thin trading, structural breaks and inflation on the dual long memory.
Design/methodology/approach
State-space GARCH-M model, Kalman filter estimation, factor-adjustment techniques and fractionally integrated models: ARFIMA–FIGARCH, ARFIMA–FIAPARCH and ARFIMA–HYGARCH are adopted for the empirical analysis.
Findings
The results indicate that the GEM is still weak-form inefficient but shows a tendency towards efficiency over time except during the global financial crisis. There also exists a stationary long-memory property in the market return and volatility; however, these long-memory properties weaken in magnitude and/or statistical significance when the joint impacts of the three aforementioned factors were taken into account.
Research limitations/implications
A forecasts of the hedging model that capture dual long memory could provide investors further insights into risk management of investments in the GEM.
Practical implications
The findings of this study are relevant to market authorities in improving the GEM market efficiency and investors in modelling hedging strategies for the GEM.
Originality/value
This study is the first to investigate the evolving efficiency and dual long memory in an SME stock market, and the joint impacts of thin trading, structural breaks and inflation on the dual long memory.
Keywords
Inflation, Structural breaks, Thin trading, Dual long memory, Evolution towards efficiency

Which formula for corporate risk-taking around the world? Exploring happiness as the “black box”
2023, Journal of Asian Business and Economic Studies
More
Abstract
Purpose
This paper examines how the degree of happiness affects corporate risk-taking and the moderating influence of family ownership of firms on this relationship.
Design/methodology/approach
The authors use an international sample of 17,654 firm-year observations from 24 countries around the world from 2008 to 2016.
Findings
Using the happiness index from the World Happiness Report developed by the United Nations Sustainable Development Solutions Network, the authors show that a country's overall happiness is negatively correlated with risk-taking behavior by firms. The findings are robust to an alternative measure of risk-taking by firms. Further analyses document that the negative influence of happiness on firm risk-taking is more pronounced for family-owned firms.
Practical implications
The paper is consistent with the notion that happier people are likely to be more risk-averse in making financial decisions, which, in turn, reduces corporate risk-taking.
Originality/value
This study contributes to the broad literature on the determinants of corporate risk-taking and the growing literature on the role of sentiment on investment decisions. The authors contribute to the current debate about family-owned firms by demonstrating that the presence of family trust strengthens the negative influence of happiness on corporate risk-taking, a topic that has been unexplored in previous studies.
Corporate governance and remuneration: a bibliometric analysis
2021, Journal of Asian Business and Economic Studies
More
Abstract
Purpose
This study aims to pinpoint gaps in the literature on corporate governance and remuneration by producing a comprehensive bibliometric review for the period 1990–2020.
Design/methodology/approach
Bibliometric analysis is the quantitative study of the bibliographic material in a specific research field. It allows an analyst to classify that material by paper, journal, author, indexation, institution or country, among other possibilities. This study reviews a total of 298 Web of Science–indexed journal articles on corporate governance and top-management remuneration schemes.
Findings
The authors find five distinct research strands: (1) firm performance and remuneration of top management, (2) the remuneration and independence of boards of directors and the efficiency of boards of directors as a governance system, (3) outside-director remuneration and the efficiency of outside directors as a monitoring system, (4) director remuneration and the corporate governance of companies and (5) the role of ownership structure and top managers' compensation schemes as corporate-governance tools. The authors identify gaps in the literature and avenues for future research for each of these strands.
Practical implications
The authors’ findings have implications for board diversity (e.g. gender diversity), remuneration policy for top-level managers and governance issues (independent directors, separation of ownership with control). This study is the only one to summarize the key topics on which top research has been focused and can be broadly used for corporate governance management perspective.
Originality/value
This paper provides an overview of how the literature on corporate governance and remuneration has developed and a synopsis of the most influential and most productive authors, countries and journal sources. It creates an opportunity for other researchers to focus on this area. This study will also serve as a foundation for future meta-analyses.
Board governance quality and risk disclosure compliance among financial institutions in Uganda
2021, Journal of Asian Business and Economic Studies
More
Abstract
"Purpose – This paper aims to examine the impact of board governance quality (BGQ) and its mechanisms, namely board activity, board independence, board communication and board expertise, on the level of risk disclosure compliance (RDC) among financial institutions (FIs) in Uganda.
Design/methodology/approach – The study adopts a cross-sectional design where data are collected through a questionnaire survey and audited financial statements of 83 FIs. The authors employ partial least square structural equation modeling (SmartPLS32.7) to test hypotheses. Findings – The authors find that the level of RDC in Ugandan FIs is low. Further, the study finds the positive relation between BGQ and RDC. Moreover, the authors find that RDC is positively and significantly related with board activity, board independence, board communication and board expertise. Furthermore, the authors find that the level of RDC is positively and significantly related to ownership type, firm size and board size, respectively. Nevertheless, industry type, number of branches and firm age are insignificantly related to RDC.
Practical implications – The study provides relevant insights into regulators and policy makers with early symptoms of potential problems regarding weak board governance in FIs. Policy makers may also use these findings as a guideline tool for improving existing board governance frameworks in place and development of new disclosure policies. In addition, the study provides an input into the review and amendments of existing corporate governance codes for the regulators.
Originality/value – This study offers the empirical evidence on the nexus between BGQ and RDC of FIs in Uganda. Moreover, the study also offers evidence on how BGQ mechanisms impact RDC. The study also further adds theoretical foundations to the RDC literature."
Earnings quality and crash risk in China: an integrated analysis
2021, Journal of Asian Business and Economic Studies
More
Abstract
Purpose - The authors provide a comprehensive empirical examination on the impact of earnings quality on stock price crash risk in China.
Design/methodology/approach - The authors acknowledge and distinguish two-dimensional proxies for earnings quality – accounting-based (earnings management degree) and market-based (earnings transparency) known in accounting and finance literature.
Findings - The authors find that both generally indicate that better earnings quality is associated with less crashes. However, extremely high earnings transparency interacted with insider trading profit can also actually exacerbate stock price crashes.
Originality/value - This study is the first to highlight the pertinence of accounting-based measures to proxy for earnings quality in a fast-growing emerging market environment such as China.
A framework of significant human resource management practices in Vietnam
2020, Journal of Asian Business and Economic Studies
More
Abstract
This paper aims at conceptualizing a framework of human resource management practices (HRMPs) that will work effectively in Vietnam. qualitative research is applied, based on a survey of 388 companies located in Ho Chi Minh city, Vietnam. HRMPs in Vietnam can be measured using seven criteria. Apart from the four traditional HRM functions, which are recruitment selection, training development, performance appraisal and compensation, HRMPs in the Vietnamese context involve three additional criteria: leading change and motivation, both based on traditional soft practices, and talent management, which is based on contemporary hard practice. The validity and reliability of the HRMPs has been confirmed. It was found that the role of HRMPs explains 43 per cent of the variation in a firm’s business performance. The findings imply that HRMPs in Vietnam, despite lagging behind global trends, are on track to catch up with them. The trend of adopting HRMPs in Vietnam continues with the emergence of traditional HRM soft practices and contemporary HRM hard practices. The typical framework of most common HRMPs in Vietnam implies that there is a need to design appropriate training programs for both HR professionals and line managers.
