  3. 7. The mobile Solow Paradox? Evidence from Swedish firms

    D-uppsats, Handelshögskolan i Stockholm/Institutionen för nationalekonomi

    Författare :Martin Vernon Fernandez; [2023]
    Nyckelord :Mobile broadband; Firm data; Productivity;

    Sammanfattning : This thesis examines the effects of 3G and 4G technologies on firm performance and productivity in Sweden. Using a comprehensive dataset of Swedish firms and data on the availability of mobile broadband technologies, the study found that while contemporary effects of the technologies were negative, they had a positive effect on firm sales when using different orders of lags.
