This paper develops a method to re-examine beta -convergence empirically by
using panel data. First. a sampling of countries is conducted, according t
o the stage of economic growth, for production function estimation, and cou
ntries are divided into the following three subsamples: a high initial inco
me subsample, a low initial income and high growth rate subsample. and a lo
w initial income and low growth rate subsample. Second, we estimate a conve
rgence process for each subsample. The coefficient restrictions in the Solo
w model were maintained only for the low initial income and high growth rat
e subsample. (C) 2001 Academic Press.
