Volatility Clustering in High-Frequency Data: A self-fulfilling prophecy? [PDF]

Clustering volatility is shown to appear in a simple market model with noise trading simply because agents use volatility forecasting models. At the core of the argument lies a feed-back mechanism linking past observed volatility to present observed ...

Rational Interacting Agents and Volatility Clustering: A New Approach [PDF]

Here, we show that agents who are ex ante rational, if allowed to interact locally, may generate clustering of volatility. Hence, there is no need to reject the notion of rationality in agent based models.Volatility Clustering; Rationality; Local ...
