Modeling Speculative Activity in the Hong Kong Residential Property Market

Using the Granger definition in a bivariate context, this paper investigates the relation between speculation and real estate prices in Hong Kong. Based on monthly data, the paper shows that in the mass residential property market, speculation and property prices are each integrated of order one, and hence cointegrated. A vector error correction model is then estimated for speculation. The error correction term is found to be statistically significant, implying Granger causality running from property prices to speculation in the mass residential property market. The empirical findings provide evidence that fluctuations in residential property prices cause fluctuations in housing speculation. A long-term solution to curb speculative activities and stabilize property prices is to increase the supply of housing land, and in turn the supply of private residential property. Steady property supply of will reduce acceleration of property prices and thus restrict speculation.
