Abstract
Thai retail stock investors face competing pressures from sustainability criteria, behavioral bias, and volatility typical of an emerging market. The study examines relationships among sustainable investment, heuristic bias, and financial literacy in predicting investment decisions, and tests risk perception as a mediator and investment horizon as a moderator. A primary survey was administered from August 1 to August 31, 2025, using self-administered questionnaires. Data from 580 retail investors across six Thai regions were analyzed in SmartPLS 4.0 using 5,000 bootstrap resamples. The results indicate that heuristic bias (β = 0.428, p < 0.001) and financial literacy (β = 0.401, p < 0.001) emerged as the strongest predictors of risk perception, and sustainable investment also had a positive effect with a smaller magnitude (β = 0.145, p < 0.001). Risk perception had a positive effect on investment decisions (β = 0.439, p < 0.001) and mediated all three predictors, with the largest indirect effect observed for heuristic bias (indirect β = 0.188, p < 0.001). Investment horizon strengthened the association between sustainable investment and investment decision (β = 0.417, p < 0.001). The results confirm policy attention to financial education and bias-awareness initiatives and support efforts to encourage longer holding periods among retail investors. Market stakeholders can also improve the quality of environmental, social, and governance disclosures and promote practical risk-assessment frameworks to enable retail investors to translate sustainability information into more informed investment decisions.

Selection of the right proxy market portfolio for CAPM
Investment Management and Financial Innovations Volume 18, 2021 Issue #3 pp. 16-26 Views: 5289 Downloads: 1988 TO CITE АНОТАЦІЯThe purpose of the paper is to select the right market proxy for calculating the expected return, since critically evaluating proxies or selecting the correct proxy market portfolio is essential for portfolio management because the change in the market portfolio proxy affects returns. In this study, monthly data of equity indices are evaluated to find out the better market proxy. The indices taken are BSE 30 (Sensex), Nifty 50, BSE 100, BSE 200, and BSE 500. The macroeconomic variables used in the study are industrial production index (IIP), consumer price index (CPI), money supply (M1), and exchange rate in India. To avoid the influence of COVID-19, the research period was from January 2013 to December 2019 to critically evaluate these proxies in order to find the most appropriate market proxy. This paper reveals a noteworthy relationship between stock market returns and macroeconomic factors, while suggesting that the BSE 500 is a better choice for all equity indices, as the index also shows a significant relationship with all macroeconomic variables. BSE500 is a composite index comprising all sectors with low, mid and large cap securities, therefore it reflects the impact of macroeconomic factors most efficiently, taking it as a market proxy. This study was carried out in the context of India and can be replicated for other countries.

Investment Management and Financial Innovations Volume 18, 2021 Issue #1 pp. 177-189 Views: 4832 Downloads: 1733 TO CITE АНОТАЦІЯThe biggest challenge facing countries, including India, is creating and managing an LCR (low carbon resilient) economy, which balances the need for high growth rates and is environmentally sustainable. The green bond market provides investors the means to help change the economy into an LCR economy. The study was undertaken to understand the key drivers and the factors influencing the individual retail investor’s decision to invest in green bonds. A survey instrument was designed and administered through the snowball sampling technique to 125 Indian respondents of various age groups who were eligible to invest in the Indian bond market. SPSS software was used to conduct a descriptive analysis followed by regression and conjoint analyses. The study results suggest that the Environmental, Social, and Governance (ESG) rating and credit rating of the green bond issuers are the key factors that influence an individual’s investment decision. The findings also highlight that incentives such as tax exemptions and awareness of green bonds also affect an investor’s decision. This research stands out as one of the first attempts to understand the Indian retail investors’ perception of a green bond.

Impact of audit committee characteristics on firm performance: Evidence from Bahrain
Problems and Perspectives in Management Volume 20, 2022 Issue #1 pp. 247-261 Views: 4822 Downloads: 1751 TO CITE АНОТАЦІЯThe purpose of this study is to analyze the relationship between different audit committee attributes and company performance in Bahrain. This paper investigates the impact of audit committee independence, size, and meeting frequency on company performance (employing ROE, ROA, and Tobin’s Q). Data from all 14 non-financial publicly listed companies on Bahrain Bourse during 2005–2019 were used. The results revealed that companies with independent audit committees and big audit committees in terms of size are performing poorly. It is also shown that the number of audit committee meetings does not affect company performance. Further, this study failed to find any association between the number of audit committee meetings and company performance. The findings show that shareholders might lack knowledge of the importance of corporate governance mechanisms. The results of this study should be of potential interest to different stakeholders, including regulators, investors, and auditors, in their attempts to improve company performance and monitoring mechanisms in emerging economies.
