This study mainly evaluates the impact of the costs of change on the market power of the firms that offer mobile telephony and internet services (Movistar, Claro, Entel and Vittel), using annual data between 2004 and 2019. First, the Lerner index, a traditional measure of market power, is constructed. To do this, an average price and marginal cost is estimated for each company. Additionally, I used method by Shy method to measure switching costs for each company based on the average price and the number of lines. Then, given the availability of panel data, the Generalized Least Squares (GLS) specification of random effects and the fixed and random effects time model are applied. I found that switching costs differ by company. In Peru's mobile services industry, I found that the highest switching costs are incurred by Claro and Movistar, but that in general these companies' switching costs have been reduced, suggesting that regulatory policies and increased competition in the mobile services industry have influenced their decrease. It is also found that there is a positive relationship between exchange costs and market power. That is, the companies with higher switching costs are the companies that have greater capacity to increase prices. Additionally, the results suggest that market power is affected by company size and HHI.
