This paper studies the introduction of causal conditional heteroskedasticity in noncausal autoregressive (AR) models. We demonstrate that, in this framework, large shocks to the innovation process driving the GARCH error term of a noncausal AR model result in heightened volatility immediately before and after a bubble crash. The non-coincidence of the σ-fields generated by past observations and past values of the GARCH process makes statistical inference nonstandard. In particular, the full quasi-maximum likelihood estimator (QMLE) is generally inconsistent. We investigate the asymptotic properties of three-step weighted least squares estimators of the AR coefficient and the QMLE of the volatility parameters. Our findings are illustrated by Monte Carlo experiments and an empirical application to financial data.
