Recent studies have found that the mobile industry increases its contribution into a development of the world’s economy. Setting a fair price for a frequency band reservation becomes an important task for national market regulators. This paper demonstrates that macroeconomic data are key determinants of prices paid for frequency band reservations in auctions organised in Europe. In an empirical analysis, we identified a positive link between log(price of 1 MHz) and log(GDP) and a negative link between log(price of 1 MHz) and log(unemployment rate). To ensure that our results are robust to the choice of the model type, we implemented two estimation methods and used two samples.
