This paper explains why the effect of income inequality on productivity and
growth is ambiguous. When income distribution exhibits inequality levels t
hat are compatible with accepted criteria, productivity and growth ensue. W
hen the divergence from an acceptable level of inequality occurs, then unde
r certain conditions, we may expect lower (higher) production levels and lo
wer (higher) levels of economic growth. (C) 2001 Elsevier Science B.V. All
