This paper investigates convergence for a group of seven countries during t
he period 1870-1914. A standard empirical growth model which includes physi
cal and human capital accumulation proves unsatisfactory in this setting. A
n alternative neoclassical open-economy factor accumulation model is propos
ed, which admits capital and labor migration, and may be extended to includ
e a moving frontier. The model explains the observed convergence pattern in
the sample and suggests that factor accumulation patterns were the prime s
ources of labor productivity convergence from 1870 to 1914. (C) 1999 Elsevi
