The purpose of this study is to analyze the casual relationship among Housing Transaction Index, Jeonse Rental Index and Interest Rate. To analyze the influence of interest rate in more detail, CD Interest rate and Spread are used as variables. Granger Casualty Test is used as a analysis tool, As a result, Spread is the cause variable of the Housing Transaction Index and the Housing Transaction Index is the cause variable of the CD Interest Rate. And also, CD Interest rate influences the Jeonse Rental Index and the Jeonse Rental Index has influence on the other variables.

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 study attempted to identify the effects of macroeconomic variables such as the All Industry Production Index, Consumer Price Index, CD Interest Rate, and KOSPI on apartment lease prices divided into nationwide, Seoul, metropolitan, and region, and to present a methodological prediction model of apartment lease prices by region using Long Short Term Memory (LSTM). According to VAR analysis results, the nationwide apartment lease price index and consumer price index in Lag1 and 2 had a significant effect on the nationwide apartment lease price, and likewise, the Seoul apartment lease price index, the consumer price index, and the CD interest rate in Lag1 and 2 affect the apartment lease price in Seoul. In addition, it was confirmed that the wide-area apartment jeonse price index and the consumer price index had a significant effect on Lag1, and the local apartment jeonse price index and the consumer price index had a significant effect on Lag1. As a result of the establishment of the LSTM prediction model, the predictive power was the highest with RMSE 0.008, MAE 0.006, and R-Suared values of 0.999 for the local apartment lease price prediction model. In the future, it is expected that more meaningful results can be obtained by applying an advanced model based on deep learning, including major policy variables

This study tests the price discovery from US Treasury bond markets to Korean bond markets using the daily returns of Korean bond data (CD, 3-year T-note, 5-year T-note, 5-year corporate note) and US treasury bond markets (3-month T-bill, 5-year T-note 10-year T-bond) from July 1, 1998 to December 31, 2003. For further research, we divide full data into two sub-samples on the basis of the start-up of bond valuation system in Korean bond market July 1, 2000, employing uni-variate AR(1)-GARCH(1,1)-M model. The main results are as follows. First the volatility spillover effects from US Treasury bond markets (3-month T-bill, 5-year T-note, 10-year T-bond) to Korean Treasury and Corporate bond markets (CD, 3-year T-note, 5-year T-note, 5-year corporate note) are significantly found at 1% confidence level. Second, the price discovery function from US bond markets to Korean bond markets in the sub-data of the pre-bond valuation system exists much stronger and more persistent than those of the post-bond valuation system. In particular, the role of 10-year T-bond compared with 3-month T-bill and 5-year T-note is outstanding. We imply these findings result from the international capital market integration which is accelerated by the broad opening of Korean capital market after 1997 Korean currency crisis and the development of telecommunication skill. In addition, these results are meaningful for bond investors who are in charge of capital asset pricing valuation, risk management, and international portfolio management.

올해들어 원유가격 및 국제금리의 하락과 수출호조에 힘입어 경상수지가 큰 폭으로 개선됨으로써 종전에 거액의 통화를 환수해 온 해외부문이 금년에는 통화철조부문으로 전환될 전망이며, 앞으로 해외부문에서의 통화증발압력이 가중될 것으로 예상됨에 따라 통화당국은 지난 7월중 무역금융 융자단가를 인하하고, 통자안정증권발행을 확대하는 등 금융면에서 통화환수노력을 경주하는 한편, 외환부문에서도 단기자본도입억제를 위하여 연지급수입기간을 단축한 바 있다. 이에 이어 지난 8월 21일에는 최근증가추세에 있는 외자대출을 억제하기 휘하여 융자대상 및 융자기간의 축소와 함께 융자비율을 인하하였으면 연지급수입대상품목을 축소하였다. 또한 외국은행 국내지점의 양도성예금증서(CD)업무 취급허용과 함께 외국은행 국내지점 스와프 한도를 축소하고 외국환은행의 수입보증금 징수대상을 기한부수입에도 확대 적용하는 등 일련의 외환부문 통화대책을 추가적으로 실시하였다.

Among several macroeconomic missteps blamed for the recent global financial crisis including the social problems of income distribution and the lack of proper financial remedies, two of them have received particular attention: the global BOP(Balance of Payment) imbalance and the misguided monetary policy. Such BOP imbalance was blamed for massive foreign exchange investment flows from Asia into the U.S., triggering the financial and real estate bubble in America. The latter refers to the excessively loose monetary policy of the U.S. Federal Reserve, which pushed financial institutions and households into reckless investment behavior in search of higher returns. Given the abuse of certain innovative financial techniques and new investment instruments that have been created in recent decades, both collateralized debt obligations (CDOs) and credit default swaps (CDS) enjoyed a symbiotic and toxic relationship prior to the financial crisis This paper is organized as follows: The first section analyzes the real causes of the recent financial crisis. The second details the role of CDOs and CDS. Then, to identify key determinants of the CDS spreads in an emerging capital market, the sample data of major Korean firms' CDS spreads are used to estimate the risk premium by utilizing the multiple regression analysis. The empirical test result indicates that Korean 3-year treasury bond rate(TYIELD), market to book value ratio(MV/BV), and assets size(INASSETS) are shown to demonstrate statistically significant influences on the changes of the CDS premium for sample firms.
