The tax, employee benefit, capital structure, and corporate control effects of ESOPs are examined by estimating the stock market reaction to ESOP announcements. This is the first empirical examination of the relationship between computed firm-specific tax savings and firm value, and therefore provides evidence that helps resolve the theoretical dispute over ESOP tax savings. The results show that investors expect ESOPs to increase cash flows through tax savings, and to reduce the likelihood of takeover for companies subject to takeover attempts when ESOPs are announced.
