본 연구에서는 GARCH 모델과 이동평균법을 이용한 국내 외환 시장에 있어서의 변동성 척도가 비교 분석되었다. 즉 두가지 알고리듬을 통하여 정보의 내용과 외환시장 변동성의 변통성 예측력을 비교하였다. 그 결과 GARCH 모형에 의할 변동성 추정치는 예측력에 있어서는 이동평균 추정치 보다 낮은 수준이지만 정보내용의 측면에서 성과가 더 좋은 것으로 나타났다. 그리고 GARCH모형에 의한 추정치는 이동평균 추정치 보다 편의성(Bias)이 낮은 것으로 나타났다. 또한 변동성의 가치에 대해서 논의하고, 이러한 변통성 추정치를 통해서 실제 환율변동을 헷지하기 위한 옵션매매에 어떻게 적용할 수 있는지를 언급하였다.

In 1970, direct overseas investment in Korean fisheries started to sell the frozen marine products to Singapore with establishing local subsidiary. Direct overseas investment in China has carried out since Korea and China established diplomat relationship in 1992. the former day, The Korea invested indirectly in China via Hong Kong. It has reported that 253 local subsidiaries applied to China government permit at the end of 2004. The results will make a decision on whether to invest continuously. The results of actual proof analysis has announced that a successful investment of fishery company is mainly influenced in its own government policy. Many advantages of tax and administration for foreign company in China have been changed and vanished comparing to the beginning time of entering china. So. it is imperative for Korean government to take measures to changing policy of Chinese government. The early days, investment of fishery company is type of resources and abundant resources will affect succeeding investment. Nowadays, the type of the investment is the production oriented investment. And then many direct investment linked the production oriented investment have been conducted in many area in China. So. the production oriented investment will affect logistics and successful investment in China. And, The factor of Market potential in Market Factors in the middle of changing market oriented investment will conclude whether to invest. As the china exchange system changed from the fixed exchange system to the fluctuating exchange system. Risk of exchange rate will affect corporate's parent business. The local risk (regulation of import and export, remittance) will affect succeeding investment of corporate's parent.

In this study, we used actual proof analysis, based on SVAR model according to economy theory, to observe the impact of actual and financial market of Korea, Japan, and China that have adopted quantitative easing export based strategy of growth, an unconventional monetary policy of the U.S. As a result of estimation, it appears that real effective exchange rate rise shock of Korea, Japan, and China against U.S. dollar has a negative influence on current account and index of industrial product, which are real economy. It can be implied that the result is driven from the fact that strong home currency of Korea, Japan, and China decreases price competitiveness of exports, causing negative influence on real economy. The real effective exchange rate shock against U.S. dollar appeared to decrease national bond rate of Korea and Japan, while increasing that of China. In instances of Korea and Japan, it is implied that national bond rate decreases as foreigner investment funds flow in, considering foreign-exchange profit through advanced financial market with high opening extent. On the other hand, because there are strong regulation on opening extent of Chinese financial markets, the influence seems to be greater for domestic policy, rather than a foreign influence. Lastly, Korea showed a more dramatic variable reaction to exchange rate shock compared to Japan or China. It is implied from the result that Korea is relatively more susceptible and fragile in regards of international status of economic size and currency.

This study is concerned with the relationship between firm's ownership structure and the co-movement of the stock return with the market return. Four different types of firm ownership, including managerial ownership, state ownership, foreign ownership, and concentrated ownership, are among the main features of the company's governance mechanism and have been separately documemented in the previous research to understand their impact on stock price synchronicity. We constructed the regression model, using stock price synchronicity as the dependent variable and the above four components of ownership structure as explanantory variables. The pooled OLS, the fixed effects model, and the random effects are employed to investigate the outcome of the study. Data used in the reserch are of public firms listed on the Ho Chi Minh City Stock Exchange (HOSE) during the five-year period term from 2015 to 2019. The data sample contains 235 companies from 10 industries with 1135 observations. The results revealed by the fixed effects model, the large ownership and the managerial ownership are found to have adverse effect on the stock price synchronicity, whereas the foreign ownership model is revealed to have positive influence on the stock return co-movement. The effect of the state ownership on the stock price synchronicity is not confirmed.

Even with the sizable Foreign Exchange (FX) holdings and good credit ratings of its top assets, Asia remains vulnerable to various shocks. This paper highlights the limited cross-border asset pledgeability as a significant factor for the lingering vulnerability in Asia. The dichotomy in asset holdings between pledgeable FX and non-pledgeable domestic assets in major economies in Asia has been the source of increasing stabilization costs as well as weakened market momentum in the region. Specifically, the peculiar feature of asset holdings in Asia reflects seriously deficient cross-border asset pledgeability that is left unaddressed. Asset pledgeability contributes toward financial stability via three channels: 1) capital market development by recognizing the role of collateral, 2) increased shock absorption capacity via collateral management, 3) and the newly activated safe asset provision. Therefore, it is crucial to go beyond the usual market development strategy and expand the overall asset pledgeability in the region that has remained unduly depressed.

UAE has rapidly developed into one of the leading global financial hubs, with significant transformations in its stock exchanges. In its attempt at economic diversification in the last two decades, the country has also taken a lead in the GCC region in introducing extensive reforms to attract FDI to the Emirates. However, oil price volatilities have posed a significant challenge to all oil-exporting countries. The main aim of this study is to explore the impact of economic diversification and oil price on the UAE stock market. The study applies Granger Causality and Vector Autoregressive Model on monthly Abu Dhabi stock exchange index, Dubai Fateh crude oil spot price, and FDI inflows during 2001-19. The short-term interbank rate has been included as a monetary policy variable. The results show a substantial difference between the two phases of reforms. Oil price and Abu Dhabi stock index show bidirectional relationship during 2001-09 but no causality was found during 2010-19. Furthermore, the second phase was characterized by unidirectional causation from FDI to ADX index. This study highlights FDI inflows as a key driver of stock market performance during the last decade and emphasizes the success of the intense reforms in the UAE initiated for the diversification of its economy.

Purpose - The purpose of this paper is to examine the connectedness between categorical economic policy uncertainty (monetary, fiscal, trade and foreign exchange policy uncertainty) indexes and option-implied volatility index in Korea, Japan and the US. Design/methodology/approach - This paper employs the Diebold-Ylmaz (2012) model based on a VAR and generalized forecast error variance decomposition. This paper also conducts regression analyses to investigate whether the volatility indexes are explained by categorical policy uncertainty indexes. Findings - First, we find the total connectedness is stronger in Korea and Japan relative to the US. Second, monetary, fiscal, and foreign exchange policy uncertainty indexes are connected to each other but trade policy uncertainty index is not. Third, the volatility index in Japan and the US is mainly associated with monetary policy uncertainty while the volatility index in Korea is explained by fiscal policy uncertainty index. Research implications or Originality - To our knowledge, this is the first study to investigate the connectedness among categorical policy uncertainty indexes and the volatility index in Korea, Japan, and the US. The empirical results on the connectedness suggest that transparent policy and communication with the market in one type of policy would reduce the uncertainty in other policies.

There are many asset prices which are interlinked and have a bearing on the stock market index. Studies have shown that the interrelationship among these asset prices vary and are inconsistent. The ultimate aim of this study is to examine the dynamic relationship between gold price, oil price, exchange rate and stock index. Monthly time series data has been utilized by the researcher to examine the interrelationship between four variables. The relationship among stock exchange rate index, oil price and gold price have been undertaken using regression and granger causality test. The results indicate that the exchange rate and oil price have an indirect influence on NIFTY; whereas gold price had a direct impact on NIFTY. It is evident from the results that volatility in the price of gold is mainly dependent on the exchange rate and vice versa. All the variables affect NIFTY in some way or the other. However, gold has a direct and vital relationship. From the study findings, it can be concluded that macroeconomic variables like commodity prices and foreign exchange rate, gold and oil, have a strong relationship on the return on securities at the national stock exchange of India.

In this study, first, current state and future prospects of indirect real estate investment systems after foreign exchange crisis are analyzed, and second, policy alternatives for activating indirect real estate investment markets are examined. After foreign exchange crisis, various indirect real estate investment systems, such as REITs, ABS and CRC, were introduced. Present market size of indirect real estate investment is not larger than expected. The reasons are the problems of incomplete system on the one hand, and real estate market conditions on the other hand. But long term prospects of indirect real estate investment markets may not be pessimistic. Considering the positive effects of indirect real estate investment systems to the real estate and financial markets, policy supports for activating indirect real estate investment market may be needed. The representative alternatives are reconciliation and integration of indirect real estate investment systems, upgrading the infrastructure of real estate industry, and activating the networks between indirect real estate investment markets and related markets such as financial makets, capital markets, restructuring markets.
