This paper investigates the spillover effects(co-movements) between korean and U.S stock market by KOSPI and DJIA Index. Especially it compare to the pre- and post period of U.S. financial crisis resulted from sub-prime mortgage loan. The main results are as follows. First, the spillover effects of DJIA(U.S. market) to KOSPI(Korean market) are strong. This result accord with the former researches on this subject. Second, spillover effects are more strong after U.S. financial crisis. A possible reason for this phenomenon is a trend which the major investors such as foreign and institutional investors in domestic stock market have more attention to U.S. stock market. Third, the spillover effects appear in the opposite direction, that is KOSPI(Korean Stock Market) to DJIA(U.S. Stock Market). It seems to be the results of asian stock market's growing infIuences to European and U.S Markets.

This paper considers the problems of martingale measures and risk-minimizing hedging strategies in the market with restricted information. By constructing a general restricted information market model, the explicit relation of arbitrage and the minimal martingale measure between two different information markets are discussed. Also a link among all equivalent martingale measures under restricted information market is given. As an example of restricted information markets, this paper constitutes a jump-diffusion process model and presents a risk minimizing problem under different information. Through $It\hat{o}$ formula and projection results in Schweizer[13], the explicit optimal strategy for different market information are given.

This study analyzed President Park's speeches and the government's industry policy in the field of information security using cognitive map. The relationship analysis between policy tool variables and policy goal variables was employed to derive revitalization strategy of information security. This paper found that entrepreneurship revitalization has very strong causality with expansion of domestic market and global market. But, on the other hand, HR development has very weak causality with job creation and future growth driver because the labor market in the information security industry is poor and its transfer rate to other industry is very high. This study showed that this cognitive map could be characterized by a scarcity of feedback loops and a strong emphasis on the positive loops in the structure of virtuous circle. In this paper, we also constructed a comprehensive cognitive map on the policy vision of information security, showing that there are a risk of cyber threat, an opportunity of new fusion security market, information security reinforcing circle, global economic circle, and domestic market circle.

본 연구에서는 주택시장과 주식시장 간의 가격 및 비대칭적 변동성 이전효과(asymmetric volatility spillover)관계를 살펴보기 위해 주택 및 주식 가격지수를 이용하여 EGARCH 모형으로 분석하였다. 분석기간은 1986년 1월부터 2021년 6월까지 이고, IMF 외환위기 전후기간의 정보 연관성을 살펴보고자 하위기간으로 1986년 1월부터 1997년 12월까지 IMF 외환위기 이전기간과 1998년 1월부터 2021년 6월까지 이후기간으로 구분하여 분석하였다. 주택시장과 주식시장 간의 비대칭 변동성 이전효과 분석에 EGARCH 모형이 적합한 것으로 나타났다. 가격 이전효과는 주식시장에서 주택시장으로 일방향으로 존재하는 것으로 분석되었으나, 반대로 주택시장에서 주식시장으로의 이전효과는 존재하지 않는 것으로 나타났다. 비대칭적 변동성 이전효과는 주택 및 주식시장 양 시장에 존재하는 것으로 나타났다. 주택시장에서는 IMF 외환위기 이전기간에는 비대칭적 변동성이 부(-)의 효과이나 그 외에는 모두 양(+)의 효과를 보였고, 반면 주식시장에서는 IMF 외환위기 전후 모든 기간에서 부(-)의 효과를 보였다. 이는 주택시장은 악재보다 호재에 더 영향을 받고, 주식시장은 호재보다 악재에 더 영향을 받는다는 것이다. 따라서 정보의 유형별로 수익의 변동성을 식별하는 것이 중요하다.

Market integration and prices in pulse crops like black gram play an important role in determining the production decisions of the farmers and diversification towards high value nutritious crops. In this context, the present study explores extent of market integration and price transmission in selected major black gram markets in Andhra Pradesh using Johansen co-integration, Vector Error Correction Model and Granger causality test. The study used monthly prices data of black gram (Rs/quintal) sourced from selected markets of Srikakulam, Krishna and Kurnool spanning January, 1990 to December, 2019. The results of the study strongly buttressed the existence of co-integration and interdependence of selected black gram markets in Andhra Pradesh. However, the speed of adjustment of the prices found to be moderate in Krishna market and quite weaker in Srikakulam market and thereby prices correct a small percentage of the disequilibrium in these markets with the greatest percentage by the external and internal forces. So, it necessitates the need for future research, to investigate the influence of external and internal factors such as market infrastructure, Government policy and self-sufficient production, product characteristics and utilization towards market integration. As there exists only unidirectional causality from Krishna to Kurnool and from Krishna to Srikakulam markets, it calls for strengthening the information technology for flow of market information regularly to help the farmers for increasing their income.
