In this note, the authors present the outcomes of two unit root tests, which allow for the existence of a break in real GDP for twelve industrial countries, using data for the period 1870-1989. The authors conclude that in the majority of the countries real per capita GDP has no unit root and that both tests yield very similar break dates. Copyright 1995 by Royal Economic Society.
