Investor mood from social media is gaining increasing attention for leading a price movement in stock market. Based on the behavioral finance theory, this study argues that sentiment extracted from social media using big data technique can predict a real-time (short-run) price momentum in Chinese stock market. Collecting Sina Weibo posts that related to COVID-19 using keyword method, a daily influential weighted sentiment factors is extracted from the sizable raw data of over 2 millions of posts. We examine one supervised and 4 unsupervised sentiment analysis model, and use the best performed word-frequency and BiLSTM mdoel. The test result shows a similar movement between stock price change and sentiment factor. It indicates that public mood extracted from social media can in some extent represent the investors' sentiment and make a difference in stock market fluctuation when people are concentrating on a special events that can cause effect on the stock market.

This study is to examine the linkage of volatility between changes in the stock market of India and other countries through the integration of the world economy. The results were as follows: First, autocorrelation or serial correlation did not exist in the classic RS model, but long-term memory was present in the modified RS model. Second, unit root did not exist in the unit root test for all periods, and the series were a stable explanatory power and a long-term memory with the normal conditions in the ARFIMA model. Third, in the multivariate asymmetric BEKK and VAR model before the financial crisis, it showed that there was a strong influence of the own market of Taiwan and UK in the conditional mean equation, and a strong spillover effect from Japan to India, from Taiwan to China(Korea, US), from US(Japan) to UK in one direction. In the conditional variance equation, GARCH showed a strong spillover effect that indicated the same direction as the result of ARCH coefficient of the market itself. Asymmetric effects in three home markets and between markets existed. Fourth, after the financial crisis, in the conditional mean equation, only the domestic market in Taiwan showed strong influences, and strong spillover effects existed from India to US, from Taiwan to Japan, from Korea to Germany in one direction. In the conditional variance equation, strong spillover effects were the same as the result of the pre-crisis and asymmetric effect in the domestic market in UK was present, and one-way asymmetric effect existed in Germany from Taiwan. Therefore, the results of this study presented the linkage between the volatilities of the stock market of India and other countries through the integration of the world economy, observing and confirming the asymmetric reactions and return(volatility) spillover effects between the stock market of India and other countries.

다양한 신재생에너지의 확대와 에너지 프로슈머의 등장으로 소비자가 직접 신생에너지 발전 설비를 설치하고, 생산한 전력을 소비, 저장, 판매까지 할 수 있도록 전력거래 시장이 빠르게 변화되고 있다. 특히 미국, 독일, 호주, 중국 등에서 전력거래에 대한 다양한 시도들이 진행 중이며, 국내에서도 에너지 신산업의 일환으로 다양한 시범 사업들이 추진되어왔다. 하지만 해외와 달리 국내에서는 그동안 추진되어왔던 대부분의 전력거래 시범 사업들이 제기능을 다하고 있지 못한 실정이다. 시장 성숙도나 시장의 저변 확대 미흡 등 많은 이유가 있겠지만, 전력거래에 대한 적극적인 활성화 지원 의지 부족과 관련 법·제도 등의 부가적인 문제들도 많은 것이 사실이다. 따라서 본 연구에서는 지금까지 많은 전력거래 시범 사업들이 추진되어 왔음에도 불구하고 외국에 비해 전력거래 시장이 활성화되지 못한 이유를 법·제도 측면에서 고찰해보고, 전력거래를 활성화 시키기 위한 법·제도 측면에서의 개선 방향과 규제완화에 대해 논의해 보고자 한다.

This paper examines what factors contribute to the entry of foreign investors to Chinese commercial banks from 1996 to 2008. Empirical results show that using survival analysis, size, liquidity ratio and non-interest incomes are important to foreign investors. This indicates that as Chinese banking system opened, foreign investors invest in bigger but financially weak banks. For Joint-Stock commercial banks, foreign investors invest in banks whose asset qualities and non-interest incomes are low. But for City commercial banks, foreign investors invest in banks that are big but have low liquidity ratios. This results indicate that because City commercial banks operate in only one city, foreign investors require minimum bank size to operate in that city.

This study examines the role of economic uncertainty in stock price determination in the domestic stock market. To this end, we analyzed the relationship between economic uncertainty indices at home and abroad (USA, China) and stock returns for non-financial companies in Korea from January 2000 to 2017. For the analysis model, the 3-factor model of Fama and French (1992) and the 5-factor model including momentum and liquidity were used. As a result of the analysis, a portfolio with a high beta of economic uncertainty showed higher stock returns than a portfolio with a low beta. This was the same as the US analysis result. Also, the analysis results using the US uncertainty index were more significant than the regression analysis results using the Korean economic uncertainty index.
