외지인은 부동산을 비싸게 매입하는가?: 제주도의 아파트 시장에 대한 실증분석
방송희 ( Song Hee Bang ),이용만 ( Young Man Lee ) 한국부동산분석학회 2013 不動産學硏究 Vol.19 No.3
There is a belief that out-of-state buyers pay more for real estate than in-state buyers in Jeju Island. We investigate whether the belief is true in condominium market, in which information on transaction prices is diffused more quickly compared with other types of houses. And we explore whether the premium is driven by anchoring-induced bias or by search cost if out-of-state buyers pay more. For the study``s purpose, we adopt a SPAR model and a repeat sale price model as alternative models instead of a conventional hedonic price model. The data of transaction prices from July 2006 to March 2013 is used to estimate our models. The analysis results reveal that the rate of premium paid by out-of-state buyers is about 4.2% for condominium. And we find that out-of-state buyers from non-high-priced regions as well as out-of-state buyers from high-priced regions pay more for condominium than in-state buyers, and that out-of-state buyers from high-priced regions pay much more than out-of-state buyers from non-high-priced regions. From the results we conclude that the premium paid by out-of-state buyers in Jeju Island is driven by anchoring effect(anchoring-induced bias) as well as by search cost.

The purpose of this paper is to develop a housing price index in the real estate auction market and to analyse the relationship between auction market and private negotiation market. We use the data on auction for condominium in Gangnam-gu, Seocho-gu and Songpa-gu, Seoul from Q1 2001 to Q2 2009. The SPAR(sale price to appraisal ratio) index model is adopted to estimate the index. After estimating the index, it is compared with the Transaction-based Housing Price Index which is made and released by the government to trace housing price change in the private negotiation market. We test null hypothesis for the equality of both indices and check up the cross correlation between two indices. We find that the null hypothesis are not rejected and the auction price index is coincident with the Transaction-base Housing Price Index. Next, we compare the auction price index with the KB Housing Price Index which is one of the appraisal-based index for the private negotiation market. We find that the auction price index is more volatile than the KB Housing Price Index and leads the KB Housing Price Index by 1 quarter. The result seems to come from the smoothing of the KB Housing Price Index.

In statistical theory, an outlier is a value that is numerically distant from overall pattern of a distribution. It may be a meaningful observation, but it comes from an error in survey, data entry and process in most cases. Detection and handling are needed because outliers by errors debase the statistical quality leading to biased parameter estimation. Generally, traditional Box-plot or Z-score are very useful for univariate outlier detection and a Median rule could be applied in the non-Gaussian case. These methods calculate the tolerance interval that defines the range of acceptable observation values. Outlier detection for periodic surveys would consider the past view, because it is based on a ratio of value comparing the current time with previous time. If time period, however, is short, a state to get many unchanged values can occur. In this case, the ratio is centered at 1, and therefore outlier detection method reflecting this factor is required. This paper considers Quartile Method with power transformation and Hidiroglou-Berthelot(1986) method that is efficient in periodic data. The methods were applied to housing sales price. We suggest an outlier detection method for real-world data. In addition, we also analyzed data using Tukey Algorithm of United Kingdom``s office of National Statistic(ONS).

현재 경매시장에서 낙찰가율(감정평가가격 대비 낙찰가격 비율)은 경매시장의 상황을 보여주는 지표로 널리 사용되고 있다. 그러나 현재 사용되고 있는 낙찰가율은 두 가지 왜곡 요인을 안고 있다. 첫 번째 요인은 감정평가시점과 낙찰시점의 차이로 인해 감정 평가가격이 현재의 시장가격을 제대로 반영하지 못한다는 점이다. 두 번째 요인은 경매 위험요인에 의해 낙찰가격이 저평가된다는 점이다. 본 논문에서는 이 두 가지 왜곡요인을 교정한 ‘진정한 낙찰가율’을 추정하고자 하였다. 이를 위해 2003년 3분기부터 2009년 2분기까지 강남구, 서초구, 송파구에서 낙찰된 아파트의 경매자료를 이용하여 ‘진정한 낙찰가율’을 추정하였다. 추정결과 세 가지 사실을 발견하였다. 첫째, 원 낙찰가율과는 달리 ‘진정한 낙찰가율’은 항상 1보다 작아 경매시장에서 아파트가 할인되어 거래되는 것으로 보인다. 다만, 이 경우 감정평가가격이 시장가격을 100% 반영한다는 전제가 필요하다. 또한 분기별로 ‘진정한 낙찰가율’이 분기별로 변동하는 것으로 보아, 낙찰가격의 할인 정도는 시장상황에 따라 다르다는 것을 알 수 있다. 둘째, ‘진정한 낙찰가율’은 감정평가가격만 조정한 낙찰가율보다 높은 것으로 나타났다. 이는 경매위험요인 때문에 낙찰가율이 낮게 평가될 수 있다는 점을 확인시켜 주는 것이다. 셋째, 아파트가격이 상승하는 시기에는 원 낙찰가율이 ‘진정한 낙찰가율’보다 상대적으로 높으며, 반대로 아파트가격이 하락하는 시기에는 원 낙찰가율이 ‘진정한 낙찰가율’보다 상대적으로 낮은 현상이 나타나고 있다. Auction price ratio(auction price to appraisal ratio) is a index shown auction market conditions in Korea. However, it doesn't correctly reflect any change of market conditions because of the following two reasons: First, appraisal doesn't fully reflect any change of market price due to time lag between point of valuation and that of successful bid. Secondly, some of real properties dealt in the auction market often involve investment risk factors like defect on right. If such auction property is bid off, it would distort auction price ratio. This study focuses upon estimating the true auction price ratio that complements two critical issues of the existing ratio(conventional auction price ratio). In order to estimate the true auction price ratio, this study uses appraisal adjusted by the KB-housing price index, and adopts hedonic price model to control risk factors. This study uses the data on auction for condominium in Gangnam- gu, Seocho-gu and Songpa-gu from Q3 2003 to Q2 2009. As a result, it is found that there are some risk factors affecting auction price ratio across three districts. Also It is found that the newly estimated true ratio from Q3 2003 to Q2 2009 is less than unit. It means that prices of real properties in auction market might be discounted. And this study is found that the conventional auction price ratio is higher than the true ratio during upward period of housing price, while during downturn period of housing price the conventional auction price ratio is lower than the true ratio.
