The European Parliament

Abstract

The European Parliament (EP) has experienced an unprecedented transformation since its first direct elections in 1979 and developed into one of the most powerful legislatures in the world. It started as a talking shop assembly of legislators seconded from the national parliaments of the European Communities’ member states who met twice a year. Now it co-decides on nearly all European Union (EU) legislation, approves the EU budget together with member state governments represented by the EU Council, scrutinizes the EU executive (i.e., the European Commission), and needs to give its consent for any new international trade agreement of the EU. This spectacular evolution has stimulated prolific research on the EP’s elections, internal organization, relations with other EU institutions, and policy impact. This bibliographical review does not purport to include all the important contributions but rather offers a map of this rich scholarly work. This article summarizes EP research into four streams. First, scholars have investigated the ability of the EP election to effectively link the EU to its citizens and increase its legitimacy and accountability. Second, an extensive body of work analyzes party competition and cooperation in the EP. A related third stream of literature studies the parliamentary organization and committees. Fourth, scholars have developed elaborate theoretical models and empirical tools to investigate the power relations between the EP and other EU institutions. These debates are discussed after a brief review of major data sources used in EP studies as well as key textbooks and journal venues for research on the EP.
