This paper reports empirical tests for the existence of rational bubbles in stock prices. The analysis focuses on a familiar model that defines market fundamentals to be the expected present value of dividends, discounted at a constantrate, and defines a rational bubble to be a self-confirming...

This paper analyzes the theoretical possibility of rationalbubbles in stock prices in a model in which stockholders haveinfinite planning horizons and in which free disposal of equityrules out the existence of negative rational bubbles. Theanalysis shows that in this framework if a positive...

The solution to a linear model in which supply and/or demand depends on rational expectations of future prices can involve three parts, which we denote as the fundamental component, the deterministic bubble component, and the stochastic bubble component. This paper explores the properties of...
