Abstract
This paper extends the Feldstein-Horioka (1980), Feldstein (1983) and subsequent studies on the degree of capital mobility, by adopting a random coefficients model. This approach is more general in that it permits inter-country variations in the degree of capital mobility to arise due to the differences in size as well as in other institutional or structural characteristics. In addition, it is a refinement of stochastic laws as defined by Pratt and Schlaifer (1984, 1988). Our results point to significant inter-country differences in the degree of capital mobility, thereby lending support to the random coefficients approach. In particular, our results indicate that, on average, the degree of capital mobility is much higher than implied by fixed coefficients approach. Finally, country size itself does not appear to bear a systematic relationship with the degree of capital mobility as suggested by Murphy (1984).
