The purpose of this study is to analyse the long run equilibrium relation between housing price,
transaction tax and interest rate using VECM. The analysis showed following results. First, a cointegration
test for showing the linear combination function between the housing price, the transaction tax, and the
interest rated showed that there was 1 cointegration with 5% significance. Second, the sign of the long run
equilibrium equation variable, which was analyzed using the 'model', showed that the sign matched the
theoretical sign, and the long-term elasticity of the housing price to the change in the transaction tax and
the change in the interest rate revealed as –1.483 and –0.320, respectively. This implies that the
long-term effect of transaction tax volatility on housing price is more significant than that of interest rate.
Third, the estimated coefficient of the interest rate of the error correction term is -0.371, which is larger
than the estimated coefficient of the other variables, so the adjustment of the deviation is estimated to be
restored to the equilibrium through the change of the interest rate. This study confirmed that the polices on
the transaction tax contributed to stabilizing housing price.
