The transition from regulated to liberalized industries has attracted a substantial amount of research which can be distilled to three main questions: 1. What are the forces that have given rise to regulatory reform? 2. What is the structure of the regulatory change which has occurred to date and is likely to occur in the immediate future? 3. What have been the effects of the reforms on industry efficiency, prices and profits? Liberalization in Aviation brings together academics and practitioners from around the world to address these questions and draw policy conclusions.
