Next Generation Access (NGA) supply side interventions—An international comparison

Over the last years, technical and economic developments towards the deployment of Next Generation (Access) Networks have triggered discussions under which circumstances investments into physical infrastructure are economically viable. In many countries the discussion has arisen regarding conditions under which private investment will/will not be undertaken and whether or not in such cases public policy measures should support deployment. This could come in different ways—from incentivizing private investments to deploying new “state-owned” networks. Public policy can have an impact for example by intervening into a competitive market. The paper tries to provide answers as to “why” such interventions and supply side policies are undertaken (thereby referring to the central role that broadband infrastructures have for the economy) and “how” such interventions take place, for example an analysis of the public policy interventions to drive Next Generation Access Network deployment. The article thereby derives policy patterns that have occurred in different regions of the world.
