An Overview of Data Resources in Real Estate Investment Market and Their Related Issues:Suggestion of Utilising Stated Preference Data

Abstract

The data utilised for the analyses of real estate market can be classified into two categories; revealed preference data （RP） and stated preference data （SP）. In practice, RP have been already used for wide range of analyses, including composition of real estate price and rent indices. Besides, in order to assess real estate market trend correctly, observation of such indices is sometimes inadequate, because indices tend to be distorted in specific cases. Hence it is desirable to complement RP with SP. This essay gives some empirical examples of the existing researches and literatures which deal with SP in real estate field, and the author suggests advantages of utilising SP as information resources.
