Comprehensive in its approach, (add comma) this book contributes to the literature on evidence-based decision making as part of the new public management. By rigorously examining the principles of better regulation and focusing on the problem of applicability and adoption of RIA practices around the world, it will greatly aid understanding of regulatory policy design and implementation.
