Cutler and Glaeser (1997) show that urban residential segregation has a str
ong adverse effect on labor market and social outcomes of young African-Ame
ricans relative to whites. We show that this effect is a fairly recent hist
orical phenomenon. There is little evidence of such an effect from 1940 to
1970; rather, it emerged between 1970 and 1980, and it grew stronger during
the 1980s. (C) 2000 Elsevier Science S.A. All rights reserved.
