From the beginning of 2000, Korean housing market has experienced cyclical volatility because of the global economic fluctuation such as steady decline in the interest rate and the house price bubble. In response to these state Korean Government announced policies about housing sales system kinds of Sales Unit Price Restraint and Post-Sales System to stabilize housing market. But such policies has brought unprecedented arguments both for and against, most of whom still seem to stick to self-centered judgement ahead of impact on housing market. In an integrated point of view, applying the system dynamics modeling, the paper aims at proposing basic Korean housing market dynamics models based on basis principles of housing market determined by supply and demand. And then, after research policies about housing sales system, analyze Impact on Korean Housing Market by change of Sales Systems applying policies to basic Korean housing market dynamics models.

The purpose of this study is to analyze the housing price variation within the redevelopment project district, affected by the characteristics of project and implementation stage. This study implemented the hedonic price model employing the actual transaction price with 24 dependent variables from 2006 to 2016 inside 19 redevelopment districts in Seoul. Research finding indicates that the larger ratio of the number of tenants and general distribution, the smaller ratio of rented households and the more positive effect of housing price. It is noteworthy that this study demonstrated the actual transaction price of houses located within the project districts by implementation stage. This study is expected to help the policy makers, the developers and the investors make more reliable decisions on the feasibility study related to the redevelopment project.

This paper aims to analyze characteristic by the cities focused on the ratio of new apartment resale that is one of the apartment unit sale market, which has been increased recently. To do so, this study examined characteristics of population, housing, residential, and economical with 162 cities and counties and performed multiple regression analysis with dependent variable, ratio of new apartment resale. As a result. the factors affecting the ratio of new apartment resale are 7variables, regional apartment rate, population increasing rate, a mount of sell in lots, housing rent price (Jeonse price) rate compared to average apartment sale price, single-person households increasing rate, apartment subscription rate and number of buyers in the area.

It has been five years since the Post-Construction Sale System of Housing was introduced. The purpose of this study is to identify objectives and effects of the Post-Construction Sale System of Housing and analyze change of profitability at different sales time from a supplier's point of view. Apartment buildings construction projects performed in Seoul are used for the case study. The present value of sales revenues, sensitivity and the present value of expected sales prices are analyzed. According to the findings, first, profits made from a Pre-construction sales system was 5.1%~6.2% higher than those from a Post-construction sales system. Among four plans of a Pre-construction sales system (A, B, C and D plan), sales revenue from the A plan, which takes a deposit at the time of starting construction, was the greatest. Second, increase of the rate of discount and decrease of sales revenues are in direct proportion. The bigger rate of discount leads actual reduction of sales revenues. Third, for the present value of sales revenues reflecting change in basic model construction cost, a Pre-construction sales system showed a little higher than that of a Post-construction sales system by approximately 2%. It should be known that this study suggests profitability of Pre-and Post-construction sales system by clearly measuring them in the supplier's point of view and calculates sales revenues, considering change of a sale price following change of sales time.

원가를 공개한다면 사실상 건설사들의 가격담합을 조장하는 결과가 되고 말 것이다. 왜냐하면 서로 경쟁사의 원가구조를 알게 되고 여기에 사회적으로 허용되는 이윤율을 알면 분양가가 얼마나 될 것인지를 짐작할 수 있어 경쟁사의 가격도 알 수 있게 된다. 그렇다면 구태여 경쟁사가 자기의 가격보다 낮은 가격으로 경쟁을 할까봐 두려워서 원가를 절감하고 나아가 가격을 낮추려는 압력이 줄어들 수밖에 없을 것이다. (중략) 이처럼 원가공개는 담합의 성공요인 중의 하나인 담합위반의 감시를 매우 쉽게 해 주고 마는 셈이다. 이런 이유로 공정거래법은 경쟁사업자들 간의 가격정보 교환을 담합의 한 수단 내지 정황증거로 보고 있다. 그런데 법령으로 가격정보의 가장 중요한 부분인 원가를 공개하라는 것은 결국 담합을 조장하여 가격경쟁을 감소시키는 결과가 될 뿐일 것이다.

This study examined the effect of the sale price by excluding the PHC-pile cost from the construction costs for basic type (CCsBT) as an additional cost. The Ministry of Land, Infrastructure, and Transport excluded the PHC-pile cost in the CCsBT and new method so that only the designed pile quantity was recognized as an additional cost. The effect on the sale price was analyzed by comparing the pile cost of the existing and new methods. For this purpose, seven cases were selected, and the PHC-pile cost was estimated. The existing method was estimated as the ratio of the pile cost to CCsBT. The new method was estimated based on the bill of quantity. As a result, the CCsBT decreased by approximately 2-3% when the PHC-pile cost was calculated in the new method. Furthermore, as a result of comparing the sale price, excluding the PHC-pile cost with the sale price, the CCsBT decreased by approximately 1%. These results are expected to help improve the understanding of the CCsBT. Also, this paper contributes to promoting national housing stability through institutional improvement.

This paper proposes a housing business model, where the presale and Chonsei housing are supplied under a presale system at the same time based on the characteristic correlation between the housing presale market and Chonsei market in Korea. Markowitz portfolio theory was used to review the risk diversification effects from the changes in the ratio between the presale housing supply and the Chonsei housing supply. The housing sale price indicator was used as a proxy variable to determine the presale housing supply. The housing Chonsei price indicator was used as a proxy variable to determine the Chonsei housing supply. The proposed housing business model was applied to major areas in Korea to examine the risk diversification effect. Comparisons of the regional portfolio analyses showed that the flexibility of the proposed housing business model can be quite effective because each regional housing market exhibits different characteristics. Market participants, such as developers, construction companies, consumers, and government, can expect various effects through the proposed housing business model. Nevertheless, policy support is necessary for practical applications of the proposed housing business model. In particular, public funds from the government need to be introduced.

PSM is widely used pricing tool in field by the reason of data collection convenience and analytical intuitiveness. However, In high involvement environment, strategic respondent bias influence in reducing the price. By using 3 empirical cases of LH apartment for sale, We found that latent consumers' recognition of the range of acceptable and the range of optimal price are lower than real estate agent representative respondents'. This phenomenon is considered loss aversion effect of prospect theory to reduce loss by reducing price, and more influenced in high involvement situation than latent consumer respondents'. Also we found PSM result using real estate representative data is more useful in real market than latent consumers data distorted by loss aversion effects. The meaning of this study is finding some limitation in PSM using consumer data generally used. In further study, development of PSM measurement tool to minimize the effect of strategic bias are need to be studied. Also some new approaches in reinterpretation of the range of acceptable price and the range of optimal price are need to be followed.
