We hypothesize that firms choose dividend increases to distribute relativel
y permanent cash-flow shocks and repurchases to distribute more transient s
hocks. As predicted, we find that post-shock cash flows of dividend increas
ing firms exhibit less reversion to pre-shock levels compared with repurcha
sing firms. We also examine whether the stock market uses the announcement
of the payout method to update its beliefs about the permanence of cash-flo
w shocks. Controlling for payout size and the market's expectation about th
e permanence of the cash-flow shock, the stock price reaction to dividend i
ncreases is more positive than the reaction to repurchases. (C) 2000 Elsevi
