メキシコの地域間収束

Quahアプローチによる実証分析

抄録

This study empirically analyzes convergence of per capita income across Mexican states during the period 1970–2006 by the method that Quah(1993) initiated. In particular, this study focuses on whether the convergence performance varies between the pre- and post-economic liberalization periods. Our estimates suggest that the convergence performance should vary between the pre- and post-economic liberalization periods. During the period 1970–1985, the estimated non-parametric density function had one peak and the distribution had been narrowing. The estimated Markov transition matrix of this period shows the catch-up of the poorer states and the ergodic distribution shows a long-term convergence to the middle group of income. On the other hand, after 1985, the twin peaks have appeared in the extended non-parametric density function and the ergodic distribution shows a long-term convergence to many poor and a few rich states.
