This paper provides an early warning indicator for bubbles in financial markets. The indicator is based on traditional … consensus bubbles and gives warning signals well ahead of the crash, in most cases as early as 12 months ahead. The indicator … also signals most of the 'negative bubbles' before their turning points …

We empirically evaluate a behavioural model with boundedly rational traders who disagree about the persistence of deviations from the fundamental stock price. Fundamentalist traders believe in mean-reversion, while chartists extrapolate trends. Agents gradually switch between the two rules,...

This paper is devoted to testing for the explosive bubble under time-varying non-stationary volatility. Because the limiting distribution of the seminal Phillips et al. (2011) test depends on the variance function and usually requires a bootstrap implementation under heteroskedasticity, we...
