The JAE Agency Effectiveness Study

Research output: Contribution to journalArticle


The Agency Effectiveness Study explores a wide range of the daily concerns faced by competition agency heads and their staff, with an emphasis on the formal and informal ways in which they are addressed. Managing and operating a competition agency is very much a process of learning-by-doing. The aim of the study is, therefore, to capture and make available the know-how that competition agency officials accumulate during their service. In particular, it aims to provide a candid account of the practical challenges encountered and solved by heads of agencies and their staff as they navigate through changing legal, social, political, and organizational landscapes.

As part of the study, current and former agency heads and competition law officials, of both young and more established agencies, were interviewed and asked for their views on a wide range of topics linked to agency effectiveness. A qualitative method was adopted to capture the knowledge and first-hand experience of competition officials. The data were collected through both face-to-face interviews and questionnaires with the aim of exploring practical, managerial, and structural challenges, which may influence an agency’s effectiveness.
