Abstract: | This article analyses the differences in institutional design in national parliamentary control over European Union affairs among EU member states. It proceeds from a preference-based perspective, drawing on the principal–agent framework, and a time-based perspective, inspired by the historical institutionalist approach. The article involves a qualitative comparative analysis of strong control and a quantitative, correlation analysis of variation in the degree of control. It argues that time-based factors provide a more persuasive overall explanation for the differences in control than preference-based factors. |
