Abstract

This paper aims to examine the impact of spectrum prices on mobile operators' industry investment using country-level data from 13 countries spanning 2013 to 2022. We employ four models to explore the quantitative evidence, with a preference for the one-step system GMM model through hypothesis testing. The results indicate that significant factors influencing investment include prior CAPEX, urban population, ARPU, GDP, and HHI, while spectrum prices and fees do not show significance. To address limitations, we suggest expanding sample sizes and incorporating additional instruments and dependent variables to establish evidence-based insights into the relationship between spectrum prices and CAPEX.
