Abstract

This study tests the existence of periodically collapsing speculative bubbles in the Tunisian stock market. We use the Phillips, Wu, and Yu (2011) and Phillips, Shi, and Yu (2015) approaches, based on right-tailed unit root tests, in order to explore the existence and to date-stamp the origination and termination of bubbles. An empirical application was conducted in the Tunisian stock market, using monthly data on stock price-dividend ratio, for the period running from January 2004 to December 2014. The empirical findings provide evidence for the existence of exuberance in the Tunisian stock market over the period and date-stamp its origination and collapse.
