The first one is to investigate the existence of chaotic structures in the oil prices, expectations of investors and stock returns by combining the Lyapunov exponent and Kolmogorov entropy, and the second one is to analyze the dependence behavior of oil prices, expectations of investors and stock returns from January 02, 1990, to June06, 2017. Lyapunov exponents and Kolmogorov entropy determined that the oil price and the stock return series exhibited chaotic behavior. TAR-TR-GARCH and TAR-TR-TGARCH copula methods were applied to study the co-movement among the selected variables. The results showed significant evidence of nonlinear tail dependence between the volatility of the oil prices, the expectations of investors and the stock returns. Further, upper and lower tail dependence and comovement between the analyzed series could not be rejected. Moreover, the TAR-TR-GARCH and TAR-TR-TGARCH copula methods revealed that the volatility of oil price had crucial effects on the stock returns and on the expectations of investors in the long run.展开更多

We proxyfor negative and positive investor sentiments using the Google Search Volume Indexfor terms related to the coronavirus disease (COVID-19) and COVID-19 vaccine, respectively. Using weekly data from March 2020 to May 2021, we document significantrelationships between positive and negative investor sentiments and stock marketreturns and volatility. Specifically, an increase in positive investor sentiment leads toan increase in stock returns while negative investor sentiment decreases stock returnsat lower quantiles. The effect of investor sentiment on volatility is consistent acrossthe distribution: negative sentiment increases volatility, whereas positive sentimentreduces volatility. These results are robust as they are corroborated by Granger causalitytests and a PVAR model. The findings may have portfolio implications as they indicatethat proxies for positive and negative investor sentiments seem to be good predictorsof stock returns and volatility during the pandemic.展开更多

Results show that investors' buying and selling behaviors are significantly affected by fund performance. The reasons that lie behind such results are mainly related to the non-persistence of fund performance. When fund performance is non-persistent, investors are not clear about the future returns on funds. So, investors, especially individual investors, would have to realize the profits on hand immediately. Meanwhile, fund investors are highly sensitive to fund age and loading fees, but not sensitive to management fees charged by funds when they buy or sell fund shares.展开更多

The study proposes arguments that in economies with high investor protection, managers prefer to manage earnings through real activity manipulation rather than through accrual manipulation because accrual manipulation is more likely to draw auditors or regulators scrutiny than real decisions about pricing and production. The study findings are consistent with prediction. Despite being in economies with high investor protection, managers still have bigger discretion in managing earnings through real activities rather than accrual manipulation.展开更多

The results indicate that the adoption of International Financial Reporting Standards [IFRS] leads to improvement in value relevance, particularly on earnings. We also examine the impact of investor protection and the deviation of local accounting standards from IFRS on the effectiveness of the IFRS adoption. The results show supporting evidence for investor protection but inconclusive evidence for accounting standard deviation. However, additional analysis indicates that the countries which apparently benefit from adopting IFRS are those with high deviation of local accounting standards from IFRS and high investor protection. The findings imply that adopting IFRS alone cannot improve value relevance of accounting information, but standard setters and regulators need to strengthen their investor protection mechanisms in order to improve the quality of accounting information.展开更多

Then the moderating effects of investor relations management on financial restatements are analyzed. The result is that the more dispersed the equity, the higher the probability of financial restatements will be (This includes the government-controlled companies). Also the higher the proportion of independent directors and the higher the level of investor relations management, the lower the probability of financial restatements will be. Furthermore, as a moderating variable, investor relations management can eliminate the negative effects of corporate governance, enhance the effect of independent directors and reduce the probability of financial restatement.展开更多

La Porta showed that there existed a simple linear relationship between corporate valuation and the holding percentage of controlling shareholders. But recent empirical evidence does not support it. A nonlinear relationship is proved between ownership structure and corporate valuaton by relaxing the assumption of La Porta＇s model in this paper. There exists a positive relation between investor protection and corporate valuation. Our empirical research shows that this relation is significantly positive indeed.展开更多

Individual investor sentiment is just like his/her personal feeling depending upon their nature, risk appetite, and market scenario. This research study investigates the investors’ reaction in the stock market for the real estate segment during the massive market crisis in developing countries. Demonetisation of 2016 in India has been taken with the purpose of implementing a pilot study to analyse the overreaction and availability bias. The primary focus was on analysing how the investors react on the information of demonetisation and their pattern of investment in the stock market with a special emphasis on real estate sector where the effect of the event had dramatically changed the stock prices. Therefore, a pre- and post- analysis had been conducted to gauge the prices, sensitivity, and reaction of investors in the stock market. The reaction of the citizens after these events was found to be drastically affected. Five real estate companies had been focused upon in this study to examine the impact of investors’ overreaction owing to the demonetisation and their investment pattern for stocks during pre- and post- demonetisation period at that timeframe. The analysis was done on a shorter period of time so that the impact of overreaction and availability bias can be critically analysed. The paper thus exhibits how investor sentiments and reaction for stock preference had changed over time through statistical study.展开更多

The policy maker should have the level of understanding and competence to blend five different factors related to organizational structure and business model of the Co-ops and the IOFs to the five similarities factors on the managerial approach of them into one marked. The study investigated five similarities factors and included into a conceptual structural model with its six measurement models, economic growth model, general national factor model, market and industry factors model, Co-ops/IOFs opportunities/threat model, Co-ops/IOFs strength /weakness model, and lastly the Co-ops/IOFs firm dynamic/active： sales, profit, and lost model. Reliability of the six similarities measurement models was tested by the Delphi technique with a sample of 33 respondents. The study found that, apart from the six measurement models, it also has two intervening factor variables that will reduce the power and magnitude of the economic growth which will come from mismanagement of policy maker： These factors are the different in intemational culture among countries, and the global warming and natural disaster from the excess consumption and excess production. These selfish, competition and economic greedy of people will lead to economic, social, and natural disaster problems. To reduce the socioeconomic disadvantages and global disaster, board＇s committee, and Co-ops manager as well as chief executive officer （CEO） of the IOFs must have a good understanding on these five similarities factors. Appropriate management of these five similarities factors will lead the firms to reach their high managerial efficiency, customer value, firm value, and finally economic growth.展开更多
