The objective of this research note is to analyze the effect of solidarity actions following the invasion of Ukraine on hotel and restaurant firms’ market value. Press releases and corporate websites of 117 companies were investigated to determine the actions taken in response to the Russian invasion of Ukraine. Then, using an event study methodology, cumulative abnormal returns were calculated following the actions taken. The results indicate that first movers benefited the most from solidarity actions, while middle-point intensity actions (versus strong or light actions) brought about the highest effects on market value.
