Labor markets during war time: Evidence from online job advertisements

This study examines the short- and medium-term impacts of the ongoing Russia-Ukraine war on the labor market for Ukrainian workers. Using a unique dataset of 5.4 million online job advertisements for Ukrainian job seekers in Poland and Ukraine over the 2021-2022 period, we show a short-term surge in demand for Ukrainians to work in Poland, while the number of jobs available in Ukraine is relatively stable. Since February 2022, the demand for soft and analytical skills in Ukraine has increased, while the demand for such skills in Poland has remained the same. Moreover, the increase in Polish jobs available to Ukrainian workers is largest for medium/highskilled jobs and female-oriented jobs. Further analysis suggests a persistent shift (to the left) in wage distribution driven by both the decline of wages within job titles and the change in the composition of jobs across Poland.
