부동산감정평가에 있어서의 피드백 영향 = A Study on Feedback in Real Estate Appraisal

다국어 초록 (Multilingual Abstract)

1. CONTENTS
(1) RESEARCH OBJECTIVES
This study aims to evaluate how much an appraiser is psychologically and behaviorally influenced by another appraiser in the process of an appraisal. A quasi-experimental design was employed in this study. First, we presented data on two commercial real estate properties in Seoul and requested appraisal from 120 appraisers to measure the behavioral and psychological variation. After one month we requested re-appraisal for the same real estate. We asked the appraisers to rate weather they thought their appraisal for the two properties was low, high, average relative to the other appraisers. And divided the appraisers into 3 groups classifying low(or high) valuation feedback group the feedback which was 30% lower(or higher) than primary appraisal expected average price, and also did not present any feedback to non valuation feedback group but requested re-appraisal.
(2) RESEARCH METHOD
quasi-experimental design
(3) RESEARCH RESULTS
As a result of the re-appraisal, 18.8% of the 80 appraisers who rather then appraisers as high or low adjusted their appraisal. We analyzed if the appraisers had been influenced psychologically and behaviorally. There were no changes in factors influencing the real estate price. So, it can be estimated that the appraisers were influenced psychologically and behaviorally, not by other environmental effects. It was also revealed that there were no statistical differences between before and after modification. Therefore, the appraisers who modified their original prices were influenced by the price that the other appraisers made, but the price difference was very negligible. An interesting the point is that appraises who modifies their appraisal were generally younger and had been in their career a shorter time than those who did not modify their appraisers.
2. RESULTS
It is estimated that appraisers can be given a certain amount of feedback about the market transaction price and the appraisal price of other appraisers in the process of an appraisal. However, the result of the quasi-experimental design show that the appraisers were seldom influenced psychologically or behaviorally by the price appraised by the other appraisers: we can conclude that most appraisers have confidence in their appraisal price.
