War and Esport: The Russian Invasions Impact on the Performance of Ukrainian and Russian Professional Players

Understanding and assessing worker performance is of major sociological and economic interest. This importance is mirrored in the extent of research that analyzes incentives and behavioral traits influencing worker performance. Most of this research focuses on workers in a peaceful or stable environment. However, a large share of the global population works in a country that is at war. To examine the situation of workers in such a vulnerable situation, micro-level data is necessary but often unavailable. Esports is an exception as data regarding professional players – workers – is accessible. Here, we examine how Ukrainian and Russian professional players behave before and since the Russian invasion. Contrary to popular thinking, we find a sizable improvement in performance. For Ukrainians, the effect is especially prominent for live events, and for Russians, for online events. Our results demonstrate that the behavior of professional gamers rapidly changed after the occupation.
