This paper sets out to date-stamp periods of historic oil price explosivity (or bubbles) us- ing the Generalized sup ADF (GSADF) test procedure suggested by Phillips et al. (2013). The date-stamping strategy used in this paper is effective at identifying periodically col- lapsing bubbles; a...

Recent work on econometric detection mechanisms has shown the effectiveness of recursive procedures in identifying and dating financial bubbles. These procedures are useful as warning alerts in surveillance strategies conducted by central banks and fiscal regulators with real time data. Use of...

This paper develops the approximate nite-sample bias of the ordinary least squares or quasi maximum likelihood estimator of the mean reversion parameter in continuous-time Levy processes. For the special case of Gaussian processes, our results reduce to those of Tang and Chen (2009) (when the...
