We analyze the regional ripple effects of both the sale prices and cheonsei prices using the global VAR(GVAR) model. The interest rate shock causes the regional sale prices to fall. Moreover, the greatest responses to the shock are those of Gangnam-gu, etc. because of there were many transactions for investment purpose. When interest rate rose, the cheonsei price in Gangnam-gu reacted greatly. Conversely, if interest rates fall, the cheonsei demand to live in Gangnam-gu increases. Furthermore, the response of sale price to the interest rate shock are greater than those of the cheonsei prices. Whereas, a positive shock on the sale price in Gangnam-gu increases the sale price there. It also raises the sale prices of the surrounding area in a similar pattern. The shock on the sale price in Gangnam-gu also increases the cheonsei price in Gangnam-gu. In addition, an increase in the sale price in Gangnam-gu leads to increases of cheonsei prices in other regions. Therefore, the recent rise of the base rate can negatively affect the sale prices, and thus a decrease in the sale price spreads to the surrounding areas. Accordingly, it is time for policy alternatives to make a soft landing in sale prices.

In this paper, a deterministic EOQ model with interest rate in which a proportion (${\beta}$) of the demand is backlogged and the rest (1-${\beta}$) is lost. The optimal order quantity is derived and the corresponding average cost is obtained, Sensitivity analysis is performed to sec the influence of interest rate on the optimal order quantity and the average cost. Finally a numerical example is given in which optimum quantities of the model developed in this study and those of the conventional EOQ model are compared.

본 연구의 목적은 보건의료산업 주식 시장에 대해 거시경제변수에 대한 요인이 미치는 영향을 알아보고자 한다. 첫째, 의약품지수는 국공채금리와 환율을 원인변수로 하며 콜금리변수와는 상호영향 관계를 가진다. 즉 금리와 환율의 변화는 의약품산업에 영향을 미치는 변수로서 주의해야 한다는 것이다. 둘째, 의료기기지수는 콜금리, 국공채금리, 환율에 대해 상호 원인변수로 작용하며 경상수지변수를 원인변수로 한다. 즉 의료기기산업에 대해 금리와 환율 그리고 경상수지의 변화가 영향을 미칠 수 있다는 것이다. 셋째, 의약품 지수에 영향을 미치는 변수의 관계를 추가적으로 분석하면 콜금리와 환율은 음(-)의 관계이며 국공채금리와는 양(+)의 관계를 가진다. 의료기기 지수에 영향을 미치는 변수의 관계를 분석하면 환율과는 음(-)의 관계이며 국공채금리와는 양(+)의 관계를 가진다.

This study suggests integrated neural network models for Interest rate forecasting using change-point detection, classifiers, and classification functions based on structural change. The proposed model is composed of three phases with tee-staged learning. The first phase is to detect successive and appropriate structural changes in interest rare dataset. The second phase is to forecast change-point group with classifiers (discriminant analysis, logistic regression, and backpropagation neural networks) and their. combined classification functions. The fecal phase is to forecast the interest rate with backpropagation neural networks. We propose some classification functions to overcome the problems of two-staged learning that cannot measure the performance of the first learning. Subsequently, we compare the structured models with a neural network model alone and, in addition, determine which of classifiers and classification functions can perform better. This article then examines the predictability of the proposed classification functions for interest rate forecasting using structural change.

최근 국제자원시장의 불안정성으로 인해 카스피해 연안 국가에 대한 관심이 고조되고 있다. 이들 국가들은 자원수출 중심으로 성장하고 있으며, 특히 카자흐스탄은 최근 10년간 높은 경제성장률을 달성하였다. 그러나 자원에 대한 수출의존도가 높은 경제구조를 가진 국가들의 경우 경제 전반이 국제자원 시세변동에 따라 크게 영향을 받을 수 있으며, 지속적인 경제성장을 저해하는 네덜란드 병에 노출될 수 있다. 최근 카자흐스탄은 우리나라와 교역 및 투자가 증가하는 등 새로운 에너지 공급처로서 대두되었다. 따라서 카자흐스탄의 경제변화는 우리나라에 있어 주요 이슈라고 할 수 있다. 이 연구에서는 카자흐스탄 경제에 네덜란드 병의 원인을 파악하기 위해 Balasa-Samuelson모형을 수정하여 1999년 1월부터 2008년 12월까지를 표본 대상 기간 동안 국제유가와 이자율, 카자흐스탄 실질환율 간의 관계를 분석하였다. 실증분석 결과 전체 표본 기간 내 국제유가와 이자율은 실질환율과 장기적 균형관계를 보이는 것으로 나타났다. 이 기간 내 국제유가와 이자율은 실질환율에 각각 부(-)의 영향을 미치는 것으로 나타나 카자흐스탄은 네덜란드 병에 노출되어 있음을 확인하였다.

This article provides integrated neural network models for the interest rate forecasting using change-point detection. The model is composed of three phases. The first phase is to detect successive structural changes in interest rate dataset. The second phase is to forecast change-point group with data mining classifiers. The final phase is to forecast the interest rate with BPN. Based on this structure, we propose three integrated neural network models in terms of data mining classifier: (1) multivariate discriminant analysis (MDA)-supported neural network model, (2) case based reasoning (CBR)-supported neural network model and (3) backpropagation neural networks (BPN)-supported neural network model. Subsequently, we compare these models with a neural network model alone and, in addition, determine which of three classifiers (MDA, CBR and BPN) can perform better. For interest rate forecasting, this study then examines the predictability of integrated neural network models to represent the structural change.

We present two approaches of the stochastic interest rate European option pricing model. One is a bond numeraire approach which is applicable to a nonzero value asset. In this approach, we assume log-normality of returns of the asset normalized by a bond whose maturity is the same as the expiration date of an option instead that of an asset itself. Another one is the expectation hypothesis approach for value zero asset which has futures-style margining. Bond numeraire approach allows us to calculate volatilities implied in options even though stochastic interest rate is considered.

Artifical Neural Network(ANN) models were used for forecasting interest rate as a new methodology, which has proven itself successful in financial domain. This research intended to construct ANN models which can maximize the performance of prediction, regarding Corporate Bond Yield (CBY) as interest rate. Synergistic Market Analysis (SMA) was applied to the construction of models [Freedman et al.]. In this aspect, while the models which consist of only time series data for corporate bond yield were devloped, the other models generated through conjunction and reorganization of fundamental variables and market variables were developed. Every model was constructed to predict 1,6, and 12 months after and we obtained 9 ANN models for interest rate forecasting. Multi-layer perceptron networks using backpropagation algorithm showed good performance in the prediction for 1 and 6 months after.

This study investigates the impact of Malaysia's capital market and other key determinants on Economic Growth from the period of 1988 to 2012. The key determinants studied are foreign direct investment and real interest rate. This study also examines the long run and short run relationship between the economic growth and capital market, foreign direct investment, and real interest rate by using bound testing cointegration of Autoregressive Distributed Lag (ARDL) and Error Correction Model (ECM) version of ARDL model. The empirical results of the study suggest that there is long- run cointegration among the capital market, foreign direct investment, real Interest rate and economic growth. The result also suggests that capital market and real interest rate have positive impact on economic growth in the short run and long run. Foreign direct investment does not show positive impact on economic growth in the short run but it does in the long run.

This study analyzes the risk selection behavior of Japanese households. The study approaches the view of 'the hyperbolic discount' which is used in behavioral economics based on the rise in mortgage lending by low-income households in the late 2000s. The study focuses on how households risk preferences vary by income levels. The study analyzes the relationship of attitude of household interest rate risk using Binomial Logistic and Heckman two-step estimation method assuming that there are only two types of Adjustable-Rate Mortgage and Fixed-Rate Mortgage. As a result of the empirical analysis, low-income households annual income tend to have a higher proportion of housing debt as same as higher interest rate risk preferences households in proportion to income growth and interest rate risk preferences. Those results indicate that there is possibility of a hyperbolic discount on low-income households in Japan, and support the hypothesis that low-income households are relatively higher household debt ratio because of high utility due to home purchase in the near future (short-term).
