We present a simple model in which rational but uninformed traders occasionally chase noise as if it were information, thereby amplifying sentiment shocks and moving prices away from fundamental values. In the model, noise traders can have an impact on market equilibrium disproportionate to their size in the market. The model offers a partial explanation for the surprisingly low market price of financial risk in the spring of 2007.

We outline a dividend signaling model that features investors who are averse to dividend cuts. Managers with strong unobservable cash earnings pay high dividends but retain enough to be likely not to fall short next period. The model is consistent with a Lintner partialadjustment model, modal dividend changes of zero, stronger market reactions to dividend cuts than increases, comparatively infrequent and irregular repurchases, and a mechanism that does not depend on public destruction of value, which managers reject in surveys. New tests involve stronger reactions to changes from longer-maintained dividend levels and reference point currencies of American Depository Receipt dividends.
