The article studies the effect of US real effective exchange rate and short-term interest rate on Chnise exports and imports using the EGARCH-GED model. This article analyze the effect of US major economic variables on China's exports and imports as the US pushes for interest rate hikes and worsens trade wars with China. The main results are as follows. The US short-term interest rate has a significant positive effect on China's trade volume. Even in the case of China's exports, US short-term interest rate has a significant positive effect. However, in the case of China's imports, in contrast to exports, US short-term interest rate do not have a significant effects and US real effective exchange rate has a significant positive effect. On the other hand, China's policy interest rate has a negative impact on China's imports and not statistically significant, but it has a significant positive effect on China's exports.

선물의 만기효과는 선물의 만기일에 가까워질수록 선물가격의 변동성이 증가하는 현상으로 사무엘슨 효과라고도 하는데, 이는 선물가격의 행태를 이해하고 투자전략과 헤지전략을 수립하는 데 매우 중요하다. 그 동안 미국을 비롯한 선진국에서 이에 대한 많은 실증연구가 있었다. 본 연구에서는 KSE의 KOSPI 200 지수선물과 KOFEX의 CD 금리선물, 국채선물, 미국달러선물, 금선물을 대상으로 선물가격의 만기효과를 검정하였으며, 그 결과는 다음과 같다. 먼저, Conover 제곱순위검정과 F-검정의 결과, KOSPI 200 지수선물에서는 만기일에 가까워질수록 변동성이 증가하는 만기효과가 나타난 반면에 CD 금리선물과 국채선물에서는 만기일에 가까워질수록 변동성이 오히려 감소하는 역 만기효과가 나타났다. 그러나 미국달러선물과 금선물에서는 만기효과를 판단하기가 어려웠다. 나아가, 연도효과를 통제한 회귀분석 결과, KOSPI 200 지수선물에서는 5% 수준에서 유의한 만기효과가 나타났다. 이는 금융선물에서 만기효과를 처음으로 발견한 Milonas(1986)의 연구와 일치하지만, Chen-Duan-Hung(1999)의 연구와는 상반된다. 그리고 CD 금리선물에서는 1% 수준에서, 그리고 국채선물에서는 5% 수준에서 각각 유의한 역 만기효과가 나타났으며, 미국달러와 금 선물에서는 만기효과가 나타나지 않았다. 또한 CD 금리선물을 제외한 KOSPI 200 지수, 국채, 미국달러 및 금 선물에서 모두 1% 수준에서 유의한 연도효과가 나타났다. 이는 Milonas-Vora(1985), Khoury-Yourougou(1993), Galloway-Kolb(1996) 등의 연구와 일치한다.

This paper investigates the spillover effect of the U.S. Interest on Korea's interest rate as well as the role of exchange rate in the spillover effects, by utilizing a open macro model on the determinants of long-term interest rates. According to the cointegration estimation and the Impulse response function, it is found that, across both long-term and short-term, there exist the spillover effect of the U.S. Interest on Korea's interest rate. The fiscal deficit and expected exchange rate have significantly positive relationship with the Koreas's long-term interest rate. Further, foreign exchange market intervention in Korea did not have significant effect on the spillover effect. Thus, this study suggests that exchange rate flexibility would not be enough to restrain the spillover effects of the U.S. interest rate.

We use a time-varying parameter vector auto regression (TVP-VAR) model to understand the impact of U.S. monetary policy normalization on Korean financial markets and capital accounts. The U.S. monetary policy is represented by the federal funds rate, term premium and credit spread. During the U.S. monetary contraction period of 2004 to 2006, changes in the federal funds rate presented negative pressure on Korean financial markets. The changes in federal funds rate also led to a simultaneous contraction in inward and outward capital flows. However, the effects of a federal funds rate shock has been reduced since 2015. On the other hand, the effects of U.S. term premiums is getting stronger after the period of quantitative easing (QE). The influence of the U.S. credit spread also significantly increased after the global financial crisis. Simulation results show that a rise in the U.S. credit spread, which can be triggered by a contractionary monetary policy, can pose a larger adverse impact on the Korean economy than a rise in the federal funds rate itself. As for capital flows, a U.S. monetary policy contraction causes an outflow of foreign investment, but the repatriation of overseas investment by Korean residents can offset this outflow.

The objective of this study is to investigate the effects of FRB's policy rate adjustments on the 10 years Korea Treasury Bond (KTB) market. Our results are summarized as follows. First, it is found that the FRB's policy rate adjustments are statistically significant positive impact on the 10 years KTB yield. Based on projection, the 10bp increases in FRB's policy rate generates 7bp higher in 10 years KTB yield. Second, the result from after the Lehman bankruptcy in '08 is found to be statistically significant, while that of before financial crisis is not. Third, the variable, in which consistent with yield difference between the 10 years UTB(US Treasury Bond) and the 10 years KTB, is found that is statistically significant positive impact in 1% significance level. And also given that Brunner(2000) exhibited that the Federal Fund Rate innovations are found to impact on other economic variables through the impulse response, the 10 years KTB yield is found to respond to innovation in the Federal Fund Rate up to about 12 months.

As the zero interest rate era was over with the end of quantitative easing, the economy of several global markets observed the fluctuations of the base interest rate. Interest rate, which is the change of money value with respect to time, is negatively correlated with construction investment. Considering the characteristics of interest rates and construction investment as economic variables, the necessity of cross-border analysis between base interest rate and construction investment was suggested in this paper. Cross-correlation analysis between base interest rates and construction investment crossing the border was performed. The effective correlations were confirmed with values varying by countries. Similar characteristics were also observed among countries with similar economy, which were then divided into three groups. Additionally, identifying the base interest rate that affects the construction investment of a particular country was made possible by reflecting a self-cycle of base interest rates. Lastly, from the result of examining the influence of each rise and fall of the interest rate, it was verified that the difference was more than twice as large in some countries. These results are expected to contribute to construction-related policy makers or investors to make decisions in response to the economic status of the construction market.

Open economy tightly works with foreign economy. This paper investigates the effect of the shock of foreign bond yield on the credit spreads of domestic corporate bonds in Korea. Foreign bond is referred to as US treasury bond. Credit spreads are defined with the difference between log yields of domestic corporate bonds and log yield of Korea treasury bond. With the data of monthly three-year AA- and BBB- corporate bond yields- ratings, monthly three-year Korean treasury bond yields, monthly US dollar foreign exchange rates, and monthly three-year US Treasury bond yields during the period from October 2000 to September 2014 including global financial crisis period, the paper documents the results as follow. First of all, the yield of Korean treasury and the credit spreads are very sensitive to the increase in the level and the volatility of the yield of the US treasury bond. Changes in the level and the volatility little affect the change of the exchange rate. Second, the change in the level and the volatility negatively affect the level of Korean treasury bond yields but lead to the increase in the level of Korean treasury bond yields at the same time. Third, there exist time lags of the increases of credit spreads by the increase in the level and the volatility. These imply that credit spreads and bond yields are very sensitive to the change in the yields of foreign bonds such as US treasury bond.

Given the US dollar's status as a global safe haven, global factors, such as US monetary policy, may have considerable impacts on financial markets in other countries. Regarding such hypothesis, this paper looked at the impacts of US monetary policy on domestic bond and FX swap markets through an event study. According to our analysis, US monetary policy had significant positive impacts on domestic interest rates. In particular, it turned out to have bigger impacts on long-term products with high term premiums. By period, the correlation between US monetary policy and domestic interest rates was not significant before the financial crisis, but was clearly positive after the crisis. The US conventional monetary policy was seen to have big impacts on short-term and medium-term KTB yields, while its unconventional monetary policy had major impacts on long-term KTB yields. Moreover, FX swap rates reacted very sensitively to US monetary policy shocks before the financial crisis, while they did not show any significant reactions after the crisis. This suggests that, in line with the covered interest rate parity, the impact of US monetary policy shocks was transmitted to domestic financial markets mainly through swap rate adjustments before the global financial crisis, but through the changes in domestic interest rates during the post-crisis period.

Three different models have been consecutively employed with the U.S. yield curve and the Korean composite stock price index, firstly to see the coupling between the economies of the U.S. and Korea, secondly to find out the time consumed completing the coupling, and lastly to figure out the impact of the recent U.S. financial crisis on this coupling. This study has, first of all, produced an empirical research outcome which proved the existence of coupling between two countries' economies. The direction of this coupling was consistent with the general expectation that when the yield spread between the U.S. 10-year Treasury Note and the U.S. 3-month Treasury Bill increased which often occurred with better prospects of U.S. economy, the asset price of emerging economies including Korea also rose reflecting the accompanying change in investment atmosphere in favor of risk. It has also found out that the degree of the coupling was maximized with a lag of one week. And finally the recent US financial crisis has been revealed to reduce the degree of the coupling by as much as half in a regression model with a dummy variable.
