The Informal Economy in the EU Accession Countries, Size, Scope, Trends and Challenges in the Process of EU Enlargement - Belev, Boyan (Centăr za izsledvane na demokracijata, 2003)

Does it represent an obstacle to further European integration? Or maybe it can serve as a bridge between accession countries and member states? The network "Toward European Integration", launched by the Bertelsmann Foundation and the World Bank, has brought together scholars and policy analysts from different countries in a first attempt to cooperate in finding answers to these and related questions
