AFAIK, in bigger (more populous) countries, it seems that the pay is going to be according to the average for the area, scaled. This is giving countries in Eastern Europe a bit of an advantage. In my case (in Bulgaria) while there is a big difference between living in Sofia and a smaller town, a lot of companies are opting to pay the same regardless of which town you are now working from. And I've already seen, pre-covid, people from western europe coming to work and live in here and now that could become even more accessible.
