Study of the Effects of Foreign Inflows on Housing Price and GRDP

This study analyzes the effect of foreigners’ inflow on house price and GRDP. The fixed effect model was estimated using the metropolitan area data and the 2-stage least squares method (2SLS) was employed to alleviate the endogeneity problem of the inflow of foreigners. The findings of this paper are the following two. First, if the number of foreigners increases by 1%, housing prices and GRDP go up about 0.16% and 0.18% respectively. Second, when dissimilarity Index, which measures the level of segregation of two groups between 0 and 1, increases by 0.1, then the housing prices decreases about 0.7%, which is statistically significant at 10% level, and GRDP decreases about 2.3%. The implication of these findings is that the influx of foreigners helps to revitalize the local economy, but it is appropriate to give attention to the residential segregation between foreigners and Koreans because the segregation gives negative impact to the housing prices and GRDP.
