This paper analyses FDI in 27 Asian countries in the period 2003-2011using a panel data quantile regression method and taking into account the heterogeneity in the data. Robustness tests are carried out by allowing for the endogeneity of the GDP growth rate (Harding and Lamarche, 2009). Overall, there is clear evidence of heterogeneity as indicated by the differences in the relative importance of the factors affecting FDI in the various countries. Moreover, the analysis by quantile confirms that bigger economies tend to attract more sizeable FDI inflows than smaller ones, as one would expect.
