This study reexamines the wealth and corporate control effects of empl
oyee stock ownership plans (ESOPs) and finds that, the adoption of an
ESOP is in general associated with positive wealth effects. However, t
he Polaroid court ruling significantly changed the market's perception
by enhancing the antitakeover role of ESOPs. A significant negative m
arket response is found only after the court ruling. Analysis of specu
lation and bid activity initiated after an ESOP adoption shows a signi
ficant decline in takeover related activity following the court decisi
on. Regression analysis corroborates this evidence. Consistent with St
ulz [Journal of Financial Economics 20 (1988) 25-54] and Harris and Ra
viv [Journal of Financial Economics 20 (1988) 55-86], the results also
suggests a non-monotonic relationship between firm value and manageri
al ownership. The results support the Scholes and Wolfson [Financial M
anagement 49 (1990) 12-28] hypothesis that ESOPs are not primarily imp
lemented for tax advantages.
