The Broadband Commission for Digital Development is an ITU (UN International Telecommunications Union) and UNESCO–backed body set up to advocate for greater broadband access worldwide. The commission’s Declaration of Broadband Inclusion for All and other reports call for governmentsto support ubiquitous fixed broadband access as a vital tool for economic growth and to reach the Millennium Development Goals. Examining the evidence, however, shows that the benefits of broadband are being oversold. Several points stand out: (i) the evidence for a large positive economic impact ofbroadband is limited; (ii) the impact of broadband rollout on achieving the MDGs would be marginal;(iii) there is little evidence ubiquitous broadband is needed for ‘national competitiveness’ or to benefit from opportunities like business process outsourcing; (iv) the costs of fixed universal broadband rollout dwarf available resources in developing countries; (and so) (v) the case for government subsidy of fixed broadband rollout is very weak. There are, however, some worthwhile policy reforms that could speed broadband rollout without demanding significant government expenditure.
