This study conducts an analysis to verify an existence of co-movement among the exchange rates of Yuan-Dollar, Yen-Dollar and Won-Dollar by using time series data. An analysis period is divided into two periods. Therefore the first analysis period is from Dec. 17, 1997 to Jul. 21th. 20, 2005 and the second analysis period is from Jul. 25th, 2005 to Nov. 20th. 2009. This paper uses VAR model and daily data of exchange rates during the period. According to the result of an empirical analysis, yuan-dollar exchange rate has affected by th other variables ; yen-dollar exchange rate. It can be proved by result of an impulse response test and variance decomposition test in the second period. Therefore the won-dollar, yen-dollar, and Yen-dollar exchange rate has been influenced each other and the relationship will be maintained.

Five diffusion models are estimated using three different foreign exchange rates to find an appropriate model for each. Daily spot exchange rates expressed as the prices of 1 euro, 1 British pound and 100 Japanese yen in US dollars, respectively denoted by USD/EUR, USD/GBP, and USD/100JPY, are used. The maximum likelihood estimation method is implemented after deriving an approximate log-transition density function (log-TDF) of the diffusion processes because the true log-TDF is unknown. Of the five models, the most general model is the best fit for the USD/GBP, and USD/100JPY exchange rates, but it is not the case for the case of USD/EUR. Although we could not find any evidence of the mean-reverting property for the USD/EUR exchange rate, the USD/GBP, and USD/100JPY exchange rates show the mean-reversion behavior. Interestingly, the volatility function of the USD/EUR exchange rate is increasing in the exchange rate while the volatility functions of the USD/GBP and USD/100Yen exchange rates have a U-shape. Our results reveal that more care has to be taken when determining a diffusion model for the exchange rate. The results also imply that we may have to use a more general diffusion model than those proposed in the literature when developing economic theories for the behavior of the exchange rate and pricing foreign currency options or derivatives.

The paper aims to test long-term and short-term causality from four exchange rates, the Korean won/$US, the Korean won/Euro, the Korean won/Japanese yen, and the Korean won/Chinese yuan, to the Korea Composite Stock Price Index in the presence of several macroeconomic variables using monthly data from January 1986 to June 2018. The results of Johansen cointegration tests show that there exists at least one cointegrating equation, which indicates that long-run causality from an exchange rate to the Korean stock market will exist. The results of vector error correction estimates show that: for long-term causality, the coefficient of the error correction term is significant with a negative sign, that is, long-term causality from exchange rates to the Korean stock market is observed. For short-term causality, the coefficient of the Japanese yen exchange rate is significant with a positive sign, that is, short-term causality from the Japanese yen exchange rate to the Korean stock market is observed. The coefficient of the financial crises i.e. 1997-1999 Asian financial crisis and 2007-2008 global financial crisis on the endogenous variables in the model and the Korean economy is significant. The result indicates that the financial crises have considerably affected the Korean economy, especially a negative effect on money supply.

International capital movement has made progress at global liberalization of finance and foreign exchange, international monetary norm changing into floating exchange rate system, easiness of collection of information and trade at improvement of information communication technology from early of 1970's. Results of empirical test for relation between foreign exchange rate or various determination factors of foreign exchange rate and interest rate are followed by next sentences. First, according to relation between foreign exchange rate and interest rate, correlation for each of variables after OECD entrance is increased. But, long-term & short-term interest rate is affected by Hanbo & Kia's bankruptcy, continuous large scale corporates bankruptcy and crisis of foreign exchange. Therefore, financial instability is occured. If portfolio investment fund has been inflow as it is mollified by continuous shortage of foreign exchange and fall of country's credit rating, it is expected to have positive effect for long-term & short-term interest rate from appreciation of won against dollar. Second, results from relation between determination factor of foreign exchange rate and interest rate are followed by next sentences. If surplus of current account and goods account is continued, yield of corporate bond is to be stable. But, margin of surplus is expected to diminish after second quarter 98, and difference between external and domestic interest (after adjusting foreign exchange rate) is to be diminished. And if net inflows of foreign investor's fund (stock and bond) is diminished, it is to have negative effect for yield of corporate bond. According to foreign investor's investment movement of previous years, hedge fund were stayed at least during two years in Mexico. It means that sudden capital outflow is not to be happened at Korea. But if external factors from depreciation of yen and China's renminbi are instable, interest rate is expected to increase from capital's outflows. Third, if it is to decrease instability of foreign exchange rate from increase in surplus of future current account, credit rating's upwardness, stability of yen and renminbi, foreign exchange rate is expected to be stable. It is expected to have continuous stability from short-term interest rate to long-term interest rate in this empirical test.

본 논문에서는 2006년 초부터 2015년 말까지 우리나라의 산업별 주가지수와 주요화폐의 환율을 이용하여 환율과 환율 변동성이 주가에 미치는 영향을 분석하였다. 주가지수로는 코스피지수와 우리나라의 대표적 산업인 음식료품, 화학, 기계, 전기전자, 종이목재, 전기가스, 운수장비, 은행 주가지수가 사용되었으며 환율의 변화를 보기 위한 주요화폐로서는 미국달러, 일본 엔, 유로, 영국 파운드가 사용되었다. 환율변화에 따른 주가의 반응분석에서는 예상한 바와 같이 전자, 운수장비 산업 주가와 환율은 정(+)의 관계를 나타내었으며 음식료품, 종이목재, 전기가스, 은행 산업의 경우도 예상한 것과 같이 주가와 환율은 부(-)의 관계를 나타냈다. 수출의 비중이 많은 기계 산업은 예상과 달리 부(-)의 반응을 보이는 것으로 나타났다. 화학 산업의 경우는 예상이 어려웠는데 분석결과 주가와 환율은 부(-)의 관계를 보여 주었다. 환율변동성에 대한 주가의 반응 분석에서는 종이목재 산업의 주가가 환율변동성에 부(-)의 반응을 나타냈다. 환율변동성에 대비한 위험관리 비용을 많이 지출하는 기업들이 종이목재산업에 속해 있는 것으로 보인다. 또한 은행산업의 주가도 환율변동성에 부(-)의 반응을 보였는데 이것은 선도환 등 외환 파생상품을 발행하여 수수료 수입이 증가하게 되는 은행산업의 주가는 환율변동성에 정(+)의 반응을 할 것이라는 예상과는 정반대의 결과였다.

In this paper, we analyze the Korean Won/Japanese 100 Yen exchange rate data based on the ARMA-GARCH model, and perform the test for detecting the parameter changes. As a test statistics, we employ the cumulative sum (CUSUM) test for ARMA-GARCH model, which is introduced by Lee and Song (2008). Our empirical analysis indicates that the KRW/JPY exchange rate series experienced several parameter changes during the period from January 2000 to December 2012, which leads to a fitting of AR-IGARCH model to the whole series.

본 연구는 일본기업의 해외진출 결정요인 및 영향력 분석에 있어 투자국인 일본 및 일본기업의 경제적 환경 변화(요인)을 선행적으로 분석한다. 최근 일본기업의 해외진출의 특징은 과거 "노동집약적 산업"이라는 점과 "사양 산업"의 해외투자라는 전통적인 형태를 유지하고 있다. 또한 중소 제조업의 경우 "비용 절약형"이라는, 그리고 대기업은 "시장 확보형"의 투자요인이 상대적으로 중요했다. 반면에 비제조업 대기업의 특징은 "전문가 확보 및 시장 관련형"이, 그리고 중소 비제조업 경우 "사회자본의 정비와 수준"이 해외진출에 주요한 요인으로 작용한다. 한편 1990-96년과 1998-2006년까지 일본기업의 해외진출에 관한 요인분석의 결과, 공통적으로 적용되는 요인은 엔환율, 금리, 임금, 기업이익, 설비투자, 소비지출이었다. 특히 회귀분석의 결과, 1990-96년에는 "저금리"의 급변이 일본기업의 해외진출에 주요하게 작용했고, 1998-2006년에는 일본의 "엔환율"이 중요한 요인으로 추출되었다. 즉, 1990-96년까지 엔화가치의 폭등에 따른 충격은 1998-2006년에 이르러 서서히 일본경제 내부에 체화 및 완충되었고 볼 수 있다. 반면에 1998-2006년에는 엔화가치의 상승 요인과 더불어 일본정부의 해외지원정책과 "저금리"하에서 일본기업의 해외진출은 가속화되었다고 말할 수 있다.

This paper tried to estimate the pass - through of exchange rate changes to export price of fishery products using export price function. The results are as follows : 1) The variable of fluctuation of exchange rate of Won(equation omitted) to Yen(equation omitted)(variable E2) is more powerful explanatory variable than that of Won to U.S. dollar to explain the fluctiation of export price of fishery products(varible $P_{t}$)- 2) The variable of fish catches(variable K $P_{t}$) is also found to be a statistically significant varible but that of producer price index is not found. 3) The variable E2 have statistically a more influence on variable $P_{t}$ than variable K $P_{t.}$ 4) The estimation shows us that 1% of fluctuation of variable E2 could result in 0.9978% of fluctuation of variable $P_{t.}$
