Asset Float and Speculative Bubbles
We model the relationship between asset float (tradeable shares) and speculative bubbles. Investors with heterogeneous beliefs and short-sales constraints trade a stock with limited float because of insider lockups. A bubble arises as price overweighs optimists’ beliefs and investors anticipate the option to resell to those with even higher valuations. The bubble’s size depends on float as inve...
متن کاملOverconfidence and Speculative Bubbles∗
Motivated by the behavior of asset prices, trading volume and price volatility during historical episodes of asset price bubbles, we present a continuous time equilibrium model where overconfidence generates disagreements among agents regarding asset fundamentals. With short-sale constraints, an asset owner has an option to sell the asset to other overconfident agents when they have more optimi...

Pertaining to Agent-based Computational Economics (ACE), this work presents two models for the rise and downfall of speculative bubbles through an exchange price fixing based on a double auction mechanism. The first model is based in a finite time horizon context where total expected dividends decrease along with time. The second model follows the greater fool hypothesis: an agent behaviour dep...
