This paper uses regime-switching econometrics to study stock market crashes and to explore the ability of two very different economic explanations to account for historical crashes. The first explanation is based on historical accounts of quot;manias and panics.quot; Its key features are that...

This paper tests between fads and bubbles using a new empirical strategy (based on switching-regression econometrics) for distinguishing between competing asset-pricing models. By extending the Blanchard and Watson (1982) model, we show how stochastic bubbles can lead to regime-switching in...

This paper explores two very different models which might account for stock market crashes. A key innovative feature of our paper is that we use the models to show how their implications for stock market crashes may be tested using switching-regression econometrics. We are careful to show that...

In this paper, we use an extension of Hamilton's (1989) Markov switching techniques to describe and analyze stock market returns. Using new tests, we find very strong evidence of switching behaviour. A major innovation of our work is to use a multivariate specification which allows us to examine...
