One model (aimed at the existence of regional air carriers) was tested. The results of the test point to the necessity to work with the second version of the model in future. Such model would be aimed at the number of regional air carriers including also other variables (for instance old vs new member countries).skhttp://creativecommons.org/licenses/by/4.0/Regional air carrierEuropean UnionEconometric modelBook of proceedingshttps://doi.org/10.26552/zbk.Z.2020.1.14
