Большинство стран приняли меры по сдерживанию коронавируса, связанные с ограничением мобильности людей. Одними из основных пострадавших от таких действий стали авиакомпании. С целью изучения влияния прямых и косвенных эффектов пандемии мы провели исследование долго- и краткосрочных факторов, влияющих на волатильность стоимости акций авиакомпаний, а именно: распространение коронавируса, внимание в соцсетях к нему, вакцинам против коронавируса и ограничительным мерам в связи пандемией. Применялась модель ARDL с оценками MG и PMG после предварительных тестов на стационарность для исследования акций авиакомпаний развитых и развивающихся стран в период наибольших противоковидных ограничений с 23 марта 2020 по 23 марта 2021 г. Мы пришли к следующим выводам. Во-первых, увеличение заболеваемости COVID-19 и смертности от него сопровождалось краткосрочным ростом волатильности стоимости акций авиакомпаний. Во-вторых, рост внимания в Twitter к ограничительным мерам в связи с COVID-19 и вакцинам против него сопровождался краткосрочным увеличением волатильности стоимости акций авиакомпаний. В-третьих, увеличение внимания в Google к ограничениям в авиакомпаниях сопровождалось долгосрочными эффектами роста волатильности акций. Полученные нами результаты демонстрируют, что в условиях распространения интернета и социальных сетей пандемия оказывала не только прямое воздействие на фондовые рынки посредством влияния на детерминанты модели экономического роста Солоу, но и косвенное воздействие через социальные сети и интернет на поведение инвесторов путем формирования у них страха и истерии.</p></abstract><trans-abstract xml:lang="en"><p>The outbreak of the pandemic has dealt a tangible blow to the global economy, in particular by causing the collapse of stock markets. Most countries have taken measures to contain the coronavirus related to the restriction of human mobility. One of the main victims of such actions were airlines. In order to examine the direct and indirect effects of the pandemic, we investigated the long- and short-term effects on airline stock price volatility of the spread of coronavirus, social media attention to it, the vaccines against coronavirus and restrictive measures in relation to the pandemic. The ARDL model with MG and PMG estimates was applied after the preliminary stability tests for airlines in developed and developing countries. We analyzed the period of the greatest anti-COVID restrictions from 23 March 2020 to 23 March 2021. We reached the following conclusions. Firstly, the increase in the number of cases and deaths from COVID-19 was accompanied by a short-term increase in the volatility of airline stock prices. Secondly, Twitter’s increased focus on COVID-19-related restrictive measures and vaccines against it was accompanied by a short-term increase in airline stock price volatility. Thirdly, the increasing attention at Google on airline restrictions has been accompanied by the long-term effects of rising stock volatility. Our results demonstrate that with the spread of the Internet and social media, the impact of the pandemic on stock markets occurs not only through direct effects on the determinants of Solow’s economic growth model, but also through indirect effects of social media and the Internet on investor behavior through the formation of fear and hysteria in them.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>COVID-19</kwd><kwd>вакцины</kwd><kwd>ограничения</kwd><kwd>внимание к COVID-19</kwd><kwd>внимание к вакцинам</kwd><kwd>внимание к ограничениям</kwd><kwd>Twitter</kwd><kwd>Google Trends</kwd><kwd>волатильность акций</kwd><kwd>авиакомпании</kwd><kwd>ARDL</kwd><kwd>MG</kwd><kwd>PMG</kwd></kwd-group><kwd-group xml:lang="en"><kwd>COVID-19</kwd><kwd>vaccines</kwd><kwd>restrictions</kwd><kwd>attention to COVID-19</kwd><kwd>attention to vaccines</kwd><kwd>attention to restrictions</kwd><kwd>Twitter</kwd><kwd>Google Trends</kwd><kwd>stock volatility</kwd><kwd>airlines</kwd><kwd>ARDL</kwd><kwd>MG</kwd><kwd>PMG</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Nguyen T.
