Recent periodical boom and burst of house price have made mortgage lending issues become the main public interest in Korean real estate market. However, because mortgage-lending issues had not been discussed until then, housing market forecasting associated with mortgage lending has been difficult while using an empirical approach. Thus, comprehensive and systematic approach is required as well as validity of mortgage lending policies should be evaluated. In this regard, this research conducts a sensitivity analysis to validate the proposed policies and estimates the effects of current policies on LTV and DTI ratios with a comparison of another policies scenario. A causal loop and sensitivity analysis using system dynamics confirmed that LTV and DTI regulation is strong clout to housing market. However, to prevent transfer of potential mortgage borrowers to nonmonetary institutions, regulations in loans of nonmonetary institutions should be practiced in accompaniment with regulations of primary lending agencies.

The prompt recovery of housing market in Korea became the national task, for which tools that can analyze the influence that changing situation of housing market and new policy may have on the housing market needs to be developed. Thus, this research intends to develop Multi-Agent Housing Market Model and simulation system in Jinju City as a study area. Analyzing the local housing market of Jinju City, then multi-agent model of housing market that consolidates 3 sub-models, house choice model, hedonic model of house price and location choice model is developed. Moreover in order to develop simulation system the model is programmed in the virtual space of which the size is $150{\times}100$ cell including physical shape of city such as road, urban facilities, land use, etc. With the system, simulations are performed to confirm the impact of urban development on the pattern of residential location. As a result, it is found that the residential location can not be easily induced when only road, commercial and convenient facilities are supplied. However, it is also found that since supplying green results in very many residences, arrangement of infrastructure and environmental factor should be considered at the same time for urban development. As conclusion, it is confirmed that the model and simulation system developed in this research smoothly works to be utilized for the analysis of diverse policy experiment and housing market.

Recently, housing prices have surged, and the government has implemented various regulations, such as finance and taxes. Because of the policy, the nationwide housing price have stabilized, but polarization has occurred. Some argue that regulation can adversely affect the actual demand. Therefore, not only the correlation between market variables but also ripple effect of policy has to be analyzed in policy planning and analysis from a microscopic point of view. In this study, a simulation model was developed by integrating system dynamics for analyzing market structure and agent-based model for modeling decision process of market participants. This research applied the financial regulation and the tax regulation to the model and evaluated the policy effectiveness. This study reveals which feedback dominates according to the policies, which have same purpose. It is because market participants make different decision for each policy. Furthermore, there were other ripple effects not only in the policy target submarket but also in other submarket.

원자재 가격 상승과 달러화 약세 등의 영향으로 내수시장과 수출시장 모두에서 어려움을 겪고 있는 보일러 제조업체들이 일제히 환기시장으로 눈을 돌리면서 시장 쟁탈전이 뜨거워 지고 있다. 실내공기 오염악화를 이유로 공동주택과 관련 시설 등에 대한 환기시스템 설치를 의무화하는 '다중이용시설 실내공기질 관리법'이 지난해 발효되면서 주택 환기시스템 관련 수요는 매년 확대될것으로 전망되고 있기 때문이다. 실제로 환기시장 규모는 2004년 500억원대에서 2005년1000억원 규모로 성장했고 지난해에는 2200억원대를 기록했다. 업계관계자들은 올해 환기시장의 규모를 약 3500억원대로 예상하고 있고 내년에는 5500억원대까지 성장할 것으로 전망하고 있다. 이에 따라 이 시장에 진출한 보일러사들은 일제히 신제품을 발표하고 나섰고 최근에는 경동나비엔과 대성쎌틱이 새롭게 시장에 진입한 상태다. 주요 보일러사들이 출시한 환기시스템의 특장점과 마케팅 방향등에 대해 알아봤다.

In this study, we evaluate the volatility of housing prices by using literature review and empirical analysis and furthermore we suggest how to improve. In order to diagnose housing market, the KB Bank's House Price Index, Real estate 114;s materials were compared. In addition, to examine the volatility, GARCH (Generalized Autoregressive Conditional Heteroskedasticity) and EGARCH (Exponential GARCH) model are used. By analysis of this research, we found the volatility of housing price also was reduced in the medium and the large houses since 1998, while the volatility of small housing price relatively was large. We proved that the price change rate of small housing was higher than the medium's. On the order hand, the supply of small apartments fell down sharply. The short-term oriented policy should be avoided, and the efficiency and credibility of policy should be increased. Furthermore, the long-term policy system should be established. and rental market's improvement is necessary for stabilization of housing market.

Although it is widely accepted that housing agents and institutions play a crucial role in (re)configuring the internal structure of housing markets, there is no much literature on the power relations among housing agents and institutions in the (re)production of housing space in the non-Western context. In this paper, founded theoretically on institutional approaches to housing, I investigate the structure of housing production and allocation, and the housing market system in South Korea. In addition, this research explores the characteristics of Korean housing policies in conjunction with the roles of and the interrelationships among housing agents in the (re)production of housing space in the Korean context. Based on the analysis of the structure of housing production and allocation in Korea, I argue that institutional approaches are valuable in investigating the housing market system in which political power relations among agents play more significant roles than pure market mechanisms in the (re)production of housing space.

Since the sub-prime mortgage crisis from the US in 2008, Korean housing market has plummeted. However, Korean local lease contract, Chonsei, price has been increasing. This increase of Chonsei price can be a threat to the low-income people because most of them prefer to live at the house with a Chonsei contract. In order to solve this problem, the Korean Government implemented several Chonsei policies to secure low-incomers' residence by decreasing the price of Chonsei; however, due to the lack of understanding on housing and Chonsei market, Korean government policy seemed to fail on getting effective results. In the housing and Chonsei market, there are many stakeholders with their own interest, hence, simple thoughts about housing and Chonsei market, such as more house supply will decrease house price, would not work in a real complex housing market. In this research, we suggests system dynamics conceptual model which consists of causal-loop-diagrams for the Chonsei market as well as the housing market. In addition, we tries to explain why the policy did not work effectively using the examples from the government's past measures. In results, Chonsei price has its own homeostasis characteristic and different price movement with housing price in the short and long term period. Unless government does not have a structural causation mind in implementing policies in the real estate market, the government may not attain intended effectiveness on both markets.
