This study raises two basic questions. How is competition in telecom and electricity governed? What explains the considerable differences in their governance regimes? To answer these questions the study compares the economic and technological characteristics of the sectors; deconstructs the telecom sector into two micro-regimes (terminal type-approval and networks interconnection) and the electricity sector into three (generation, transmission, distribution); defines intergovernmentalism, supranationalism, liberalism, and étatism for each of the five segments of the sectors; distinguishes three different kinds of competition – deregulated competition, regulation-of-competion, and regulation-for-competition; and deconstructs the European policy game into three different games (sectorial, national, and union). The European Union's policy choices are: supranational governance in telecom and intergovernmental governance in electricity. The introduction of competition as an administrative process leaves considerable room for entrepreneurship and political choice by European nation-states and strengthens their regulation capacities. Differences in the governance regime for telecom and electricity are explained by a state-centered multi-level approach.
