We examine the effect of corporate diversification on the equity-issue proc
ess in a sample of 641 equity issues from 1983 to 1994. We find that issues
by diversified firms are viewed less negatively by the market than are iss
ues by focused firms. This finding supports the hypothesis that diversifica
tion helps alleviate asymmetric information problems. Our results appear in
consistent with the hypothesis that reduced transparency exacerbates asymme
tric information problems for diversified firms. The results also appear in
consistent with the hypothesis that the market anticipates that the funds a
n raised from equity issues by diversified firms will be invested in partic
ularly poor projects.
