In Indonesia, as in other countries, a large proportion of tax returns are filed at the last minute. In a population-wide randomised controlled trial (n = 11,157,069), we evaluated the impact of behavioural email prompts on the proportion of annual tax returns filed at least two weeks before the deadline; and overall filing rate. In two control conditions, taxpayers either received no email or an email used in prior years, emphasising regulatory information. The five treatments informed by…

The study investigates minimum requirements and options for standardisation of energy offers and bills that ensure increased clarity and comparability, and puts forward better alternative “bill designs”. The study also examines the main factors discouraging energy consumers from switching, with a focus on the impact of exit fees in this decision. Finally, price comparison tools (PCTs) in the energy sector are examined and (independent) verification schemes for such tools are identified.

The results show that the most effective variant − in the 6 days after receiving the text message − led to a 3.2% increase in the number of vaccinations administered. This was the text message saying 'Jouw boosterprik ligt voor je klaar' (You can now book your booster vaccination) plus a randomly allocated date, time and location. Why…

Not all UWV clients who receive unemployment benefit post their CVs on werk.nl. This prevents them from being found or matched for a job. Would it help to send them a reminder to their personal Work Folder as well as a text message? Yes it would: this experiment shows that five times more clients are then prompted to put their CV online, compared to clients who are not sent a reminder. Why this experiment was conducted: missing CVs 25% of jobseekers on unemployment benefit who are asked to post…

How can response rates to questionnaires be increased? In the first quarter of 2023, some of the participants in a CBS survey received a letter in which the call-to-action appeared as far as possible at the top of the letter. The other participants received standard letters. The analyses showed that the standard letters produced a significantly higher response rate than the letters in which the call-to-action was placed at the top. Why this experiment was conducted: high response rate is…

Finally, it proposes policy tools to enable and encourage consumers to…
