TY - JOUR AU1 - Barsky, Robert, B. AU2 - , De Long, J. Bradford AB - Abstract Major long-run swings in the U. S. stock market over the past century are broadly consistent with a model driven by changes in current and expected future dividends in which investors must estimate the time-varying long-run dividend growth rate. Such an estimated long-run growth rate resembles a long distributed lag on past dividend growth, and is highly correlated with the level of dividends. Prices therefore respond more than proportionately to long-run movements in dividends. The time-varying component of dividend growth need not be detectable in the dividend data for it to have large effects on stock prices. * We would like to thank George Bulkley, Martin Evans, James Hamilton, Bruce Lehmann, Gregory Mankiw, David Romer, Robert Shiller, Andrei Shleifer, Lawrence Summers, Robert Waldmann, many seminar participants, and referees of this Journal for helpful discussions and their very valuable comments.
