The version of scholarly record of this article paper is published in Applied Economics (2020), available online at: https://doi.org/10.1080/00036846.2020.1781776In this study we assess the impact of the political and economic blockade of Qatar, as well as four other events related to the blockade on Qatar’s stock market volatility. One of these events occurred before the June 5 2017 blockade while the others occurred after. We use volatility event-study approach to test the abnormal unsystematic volatility in stock returns. We reveal that stock market volatility has reacted significantly to the blockade as well as to other related events that happened before and after the blockade. Our findings highlight the importance of continuing, and even bolstering, the ongoing mediation efforts to reduce the risk of a resurgence of hostilities. As there is no resolution yet, there is still a risk of future market volatility and thus changes in portfolio allocation and investment decisions not only in Qatar but also in the GCC. © 2020, © 2020 Informa UK Limited, trading as Taylor & Francis Group.enPermission to reuse the abstract has been secured from Taylor & Francis and Copyright Clearance Center.Comparative analysisevent studyQatar blockadevolatilityArticleCopyright : © 2020 Informa UK Limited, trading as Taylor & Francis Group
