Based on econometric modelling, this study provides additional evidence of the contribution of broadband and digital transformation to the economy and the impact of institutional and regulatory variables to the development of the digital ecosystem. The study is structured around three analyses: • The economic impact of fixed and mobile broadband: This analysis verifies whether the original models, which explain broadband economic contribution developed in 2010, are still valid. In this context, and on the basis of large data sets, the analysis tests whether the economic impact of broadband is increasing with penetration (the so-called return to scale effect). Alternatively, the models may determine that broadband economic impact is undergoing a saturation effect and, therefore, diminishing returns. Finally, the analysis searches for any differences between fixed and mobile broadband economic impact. •The economic impact of digitization: The digitization concept is much larger in scope than broadband, as it encompasses the infrastructure of digital services, connectivity of devices, the digital transformation of households and production, the development of digital industries, and the availability of digital factors of production. In this context, it is pertinent to raise a question that goes beyond the economic impact of broadband: What is the impact of digitization on GDP and productivity? •The impact of policy and regulatory frameworks on the growth of markets for digital services and applications: This analysis looks at the impact of regulation and institutions on the development of the digital economy. Considering that the growth of digitization is primarily driven by the private sector, this analysis also looks at the roles that policy and regulatory variables play, and if these factors are important as drivers of growth in the digital economy. Analysis is structured around a review of the research evidence, a resentation of the econometric models, and a discussion of results.
