We find that tariff announcements lead to negative (cumulative) average abnormal stock returns. These negative wealth effects occur regardless of whether the Trump administration imposes safeguard tariffs to protect domestic industries or foreign countries announce retaliatory tariffs. Moreover, the adverse impact is primarily driven by announcements involving China, with variations linked to sector-specific, tariff, trade, and firm characteristics.","lang":"eng"}]},{"language":[{"iso":"eng"}],"_id":"21539","article_number":"101717","user_id":"21222","doi":"10.1016/j.frl.2020.101717","publication_identifier":{"issn":["1544-6123"]},"author":[{"last_name":"Ortmann","first_name":"Regina","full_name":"Ortmann, Regina"},{"last_name":"Pelster","first_name":"Matthias","full_name":"Pelster, Matthias"},{"first_name":"Sascha Tobias","last_name":"Wengerek","full_name":"Wengerek, Sascha Tobias"}],"title":"COVID-19 and investor behavior","status":"public","year":"2020","publication_status":"published","date_updated":"2022-01-06T06:55:03Z","date_created":"2021-03-18T12:02:09Z","department":[{"_id":"187"}],"type":"journal_article","citation":{"bibtex":"@article{Ortmann_Pelster_Wengerek_2020, title={COVID-19 and investor behavior}, DOI={<a href=\"https://doi.org/10.1016/j.frl.2020.101717\">10.1016/j.frl.2020.101717</a>}, number={101717}, journal={Finance Research Letters}, author={Ortmann, Regina and Pelster, Matthias and Wengerek, Sascha Tobias}, year={2020} }","ama":"Ortmann R, Pelster M, Wengerek ST.
