Abstract: This paper sets out to date-stamp periods of historic oil price explosivity (or bubbles) using 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 collapsing bubbles; a feature found lacking with previous bubble detecting methods. We set out to identify bubbles in the real price and the nominal price-supply ratio of oil for the period 1876 - 2014. The recursive identification algorithms used in this study identifies several periods of significant explosivity, and as such provides future researchers with a reference for studying the macroeconomic impact of historical periods of significant oil price build-ups.
