Periodically collapsing Evans bubbles and stock-price volatility
Rotermann Benedikt; Wilfling Bernd
Zusammenfassung
This paper analyzes conditional stock-price volatility within in present-value framework including (rational) periodically collapsing bubbles as introduced by Evans (1991). To this end, we derive an analytically closed-form volatility formula of the stock price. The formula establishes a direct link between the bubble component and stock-price volatility. Using a Bayesian Monte-Carlo estimation technique (the particle filter), we demonstrate how to fit the parametric volatility equation to stock-market data.
