This paper reexamines some recent tests of whether holders of shares with higher dividend yields receive higher risk-adjusted rates of return to compensate for the heavier taxes on dividend payments than on long-term capital gains. Our particular concern is with tests using short-run measures of dividend yield--that is, measures that seek to deduce the differential tax burden on dividends over long-term capital gains from differences in rates of return on shares that do not pay a cash dividend during the return interval. We show that such measures are inappropriate for that purpose. Any yield-related effects associated with such measures must arise from sources other than the long-term tax differential. For the short-run measures considered here, the yield-related effects found in some tests are traced to biases, one of a fairly subtle kind, introduced by dividend announcement effects.
