This paper provides an empirical analysis how tariff diversity affects broadband uptake, utilizing a new data set with 1497 fixed-line and 2158 mobile broadband tariffs from 91 countries across the globe. An instrumental variable approach is applied to estimate the demand for fixed broadband...

This paper provides an empirical analysis how tariff diversity affects fixed-line broadband uptake, utilizing a new data set with 1497 fixed-line and 2158 mobile broadband tariffs from 91 countries across the globe. An instrumental variable approach is applied to estimate demand, controlling for...
