The toolbox of consumer policy is diverse, ranging from legal requiremens and their enforcement, to incentives and "nudges", to consumer information and education. However, not every instrument is suitable for all consumer policy challenges, and they can—depending on the respective consumer groups and contexts—exert different effects.

We support consumer policy-makers in assessing the effectiveness and efficiency of consumer policy instruments ex ante and evaluating them ex post. We propose measures to tailor the mix of tools so that maximum benefit for consumers is achieved with the least possible unintended side effects. Our work is evidence-based and takes international experience into account.
