한국 소비자물가지수에서 전세지수는 단일 품목으로 최대 가중치(5.4%)를 차지하고 있으며, 전세가격 자체의 변화는 그대로 주거비 변화로 반영되고 있다. 전세는 주거서비스 비용을 자본화한 가격으로 일차적으로 월세 변화에 연동되지만, 실질적 비용인 월세와 무관하게 금리 변동에 의해서도 영향을 받는다. 따라서 전세가격을 그대로 소비자물가지수에 반영하면, 주거서비스 가격 변화 이외의 부분에 대해서도 비용 변화로 인식될 수 있다. 소비자물가지수 전세지수와 월세지수의 장기시계열을 살펴본 결과, 전세지수는 연평균 2.3% 상승하고 있으나 월세지수는 0.9% 상승하고 있어 추세적인 격차가 나타났다. 우리 경제의 금리가 서서히 하락하면서 자본화된 전세지수가 월세지수보다 더 빠르게 상승한 것으로 판단된다. 주거서비스 비용 변화를 반영할 수 있도록 전세지수의 대체 변수를 사용하여 소비자물가지수를 작성한 결과, 전반적으로 새로운 CPI는 기존의 CPI보다 물가상승률이 낮게 추정되었으며, 자가주거비를 포함하면 이러한 효과가 두드러지게 확대되었다.

The price structure of housing market varies depending upon market price policy rather than low or high price policy because of IMF. The object of this study is to develop an analysis system for analyzing housing market and its demand. The analysis system consists of four major categories: macro index analysis, market decision analysis, housing market analysis, and consumer analysis. We model each category by using a variety of techniques such as generalized linear model, categorical analysis, bubble analysis, drill-down analysis, price sensitivity meter analysis, optimum price index analysis, profit index measurement analysis, correspondence analysis, conjoint analysis, and multidimensional scaling analysis. Seoul apartment data is analyzed to demonstrate the practical usefulness of the system.

Purpose - In Korea, there has been a recent trend that shows housing prices have risen rapidly following the International Monetary Fund crisis. The rapid rise in housing prices is spreading recognition of this as a factor in housing price volatility. In addition, this raises the expectations of housing prices in the future. These expectations are based on the assumption that a relationship exists between the current housing prices and expected housing prices in the real estate industry. By performing an empirical analysis on the validity of the claim that an increase in current housing prices can be correlated with expected housing prices, this study examines whether a long-term equilibrium relationship exists between expected housing prices and existing housing prices. If such a relationship exists, the recovery of equilibrium from disequilibrium is analyzed to derive related implications. Research design, data, and methodology - The relationship between current housing prices and expected housing prices was analyzed empirically using the Vector Error Correction Model. This model was applied to the co-integration test, the long-term equilibrium equation among variables, and the causality test. The housing prices used in the analysis were based on the National Housing Price Trend Survey released by Kookmin Bank. Additionally, the Index of Industrial Product and the Consumer Price Index were also used and were obtained from the Bank of Korea ECOS. The monthly data analyzed were from January 1987 to May 2015. Results - First, a long-term equilibrium relationship was established as one co-integration between current housing price distribution and expected housing prices. Second, the sign of the long-term equilibrium relationship variable was consistent with the theoretical sign, with the elasticity of housing price distribution to expected housing price, the industrial production, and the consumer price volatility revealed as 1.600, 0.104,and 0.092, respectively. This implies that the long-term effect of expected housing price volatility on housing price distribution is more significant than that of the industrial production and consumer price volatility. Third, the sign of the coefficient of the error correction term coincided with the theoretical sign. The absolute value of the coefficient of the correction term in the industrial production equation was 0.006, significantly larger than the coefficients for the expected housing price and the consumer price equation. In case of divergence from the long-term equilibrium relationship, the state of equilibrium will be restored through changes in the interest rate. Fourth, housing-price volatility was found to be causal to expected housing price, and was shown to be bi-directionally causal to industrial production. Conclusions - Based on the finding of this study, it is required to relieve the association between current housing price distribution and expected housing price by using property taxes and the loan-to-value policy to stabilize the housing market. Further, the relationship between housing price distribution and expected housing price can be examined and tested using a sophisticated methodology and policy variables.

Purpose - Since COVID-19, the government's expansion of liquidity to stimulate the economy has resulted in an increase in private debt and an increase in asset prices of such as real estate and stocks. The recent sharp rise of the US Federal fund rate and tapering by the Fed have led to a fast rise in domestic interest rates, putting a heavy burden on the Korean economy, where the level of household debt is very high. Excessive household debt might have negative effects on the economy, such as shrinking consumption, economic recession, and deepening economic inequality. Therefore, now more than ever, it is necessary to identify the causes of the increase in household debt. Design/methodology/approach - Main methodology is regression analysis. Dependent variable is household loans from depository institutions. Independent variables are consumer price index, unemployment rate, household loan interest rate, housing sales price index, and composite stock price index. The sample periods are from 2017 to May 2022, comprising 72 months of data. The comparative analysis period before and after COVID-19 is from January 2017 to December 2019 for the pre-COVID-19 period, and from Jan 2020 to December 2022 for the post-COVID-19 period. Findings - Looking at the results of the regression analysis for the entire period, it was found that increases in the consumer price index, unemployment rate, and household loan interest rates decrease household loans, while increases in the housing sales price index increase household loans. Research implications or Originality - Household loans of depository institutions are mainly made up of high-credit and high-income borrowers with good repayment ability, so the risk of the financial system is low. As household loans are closely linked to the real estate market, the risk of household loan defaults may increase if real estate prices fall sharply.

Purpose - We investigate the relationship between economic policy uncertainty (EPU) of the US and China and housing distribution economy in Korea using EPU indexes of two countries and the economic indicators in Korea. Research design, data, and methodology - We use the data such as the Korean housing price stability index (HPSI), housing purchase price index (HPPI), housing lease price index (HLPI), banking stock index (BSI), and consumer price index (CPI) with EPU indexes from January 1999 to December 2017. As an empirical methodology, we select the vector error correction model (VECM) due to the existence of cointegration. Result - As results of the impulse response function, the impact of the US EPU index has initially a negative response on the Korean HPSI, HPPI, and HLPI referring the housing distribution market including the economic variables, BSI, and CPI. Likewise, the impact of index in China has initially a negative response on economic indicators except the BSI in Korea. Conclusions - This study shows that the EPU index of the US has significantly negative relationships on all economic indicators in Korea. In this study, we reveal EPU of the US and China has dynamic impact on housing distribution economy returns in Korea.

The purpose of this study was to examine how much the cost of marriage ceremony has increased according to the economic growth. The relationship between marriage expenditures and other comparison variables such as per capital GNP, monthly income, consumer price index was particularly examined. All the money values were adjusted by consumer price index. Data from the Central Committee for Promotion of Saving were used in this study. The results of this study follow. First, nominal and actual total outlay of marriage ceremony has continuously increased. Total marriage ceremony cost was positively correlated with the housing price so that bridegroom’s outlay were greater than that of bride’s one since bridegroom was more likely to have the responsibility for the price of new couple’s house. Second, it was found that increased percentage rate of marriage ceremony cost was greater than that of national economic growth. The total marriage expenditure was about 10 times as much per capital income in 1990. Third, it was revealed that housing cost increased three times from 1990 to 1995, and marriage ceremony expense was accordingly increased twice during the same periods. Such trends tend to increase continuously. Last, the marriage cost percentage to monthly income called marriage expenditure share increased by 1990 and then decreased. Such a decreasing trend can be explained by the increased amount of income partly due to the higher wage rate compared to other conditions since 1990.
