A large body of empirical evidence suggests that beliefs systematically deviate from perfect rationality. Much of the evidence implies that economic agents tend to form forecasts that are excessively influenced by recent changes. We present a parsimonious quasi-rational model that we call natural expectations, which falls between rational expectations and (na�ve) intuitive expectations. (Intuitive expectations are formed by running growth regressions with a limited number of right-hand-side variables, and this leads to excessively extrapolative beliefs in certain classes of environments). Natural expectations overstate the long-run persistence of economic shocks. In other words, agents with natural expectations turn out to form beliefs that don't sufficiently account for the fact that good times (or bad times) won't last forever. We embed natural expectations in a simple dynamic macroeconomic model and compare the simulated properties of the model to the available empirical evidence. The model's predictions match many patterns observed in macroeconomic and financial time series, such as high volatility of asset prices, predictable up-and-down cycles in equity returns, and a negative relationship between current consumption growth and future equity returns.

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. (JEL D82, G35)
