초록
본 연구는 글로벌 경제통합화를 통한 인도의 주식시장과 다른 주식시장의 변동성간에 연관성을 파악하고자 하였다. 본 연구의 결과, 첫째, 분산비검정에서 모든 기간의 주식시장은 자기상관이 존재하지 않았고 또한 고전적 RS모형에서 모든 기간이 자기상관이 존재하지 않았으나, 수정된 RS모형에서도 거의 모든 기간에서 장기기억이 존재하였다. 둘째, 단위근검정에서 모든 기간이 단위근이 존재하지 않아 시계열이 안정적이고, 모든 수정
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.
