E-mail: firstname.lastname@example.org Proposed paper for presentation at the 2006 ASSA Conference in Boston, January 6-8, 2006 Preliminary Draft dated: 31 March 2005 Abstract This paper studies the causal relationship between residential land and house prices. It essentially seeks to examine whether high land prices in urban areas are caused by high property prices or whether the reverse is true, namely high property prices leads to high land prices. The former hypothesis is based on the cost pricing theory of real estate, whilst the latter is based on the conventional residual method of valuation. To carry out the co-integration analysis, we first construct a constant quality price index for urban land using the methodology proposed by Greenless (1980) and Clapp (1990). The resulting urban land index is then matched against the residential property price index to determine the dynamics of their long-term relationships. The results of our Granger causality test modeled in an error-correction framework suggest that the two series are integrated. The evidence seems to indicate that land prices lead private property prices by approximately four quarters. Key words: price discovery, urban land price, private residential market.
