The 'Doe meer met taal' (Get more out of language) campaign was launched to reach out to individuals with limited literacy skills whose mother tongue is Dutch. At its conclusion, people in the target group said they felt more motivated to improve their language skills. They are also more inclined to take proactive steps, for example by engaging in language-related activities at home. 66,000 people visited the campaign website.

Land tax is payable in Queensland on properties valued over a certain threshold. The Queensland Office of State Revenue can approve land tax exemptions for a range of reasons that include landowners’ principal place of residence and business of primary production. Once claimed, the exemption continues to apply indefinitely, which is appropriate as long as landowners are entitled to continue to claim the exemption. However, landowners who claim the exemption are obligated to inform the…

Can interventions in supermarkets reduce household food waste? A randomised controlled trial of…
The study was conducted in collaboration with eight supermarkets from two of the largest Swedish supermarket chains. The stores provided the natural environment in which to conduct an experiment using real shoppers and real purchases, without shoppers being aware of the study. Four different interventions (different price displays) were designed, based on insights from behavioural science. These signs were tested in a randomised controlled study for two common and perishable vegetables –…

Reduced calf mortality at dairy farms: how can dairy farmers be encouraged to take proper care of…
To reduce calf mortality rates, the Netherlands Food and Consumer Product Safety Authority (NVWA) developed various letters for distribution amongst three subgroups of dairy farmers. The impact measurement shows that calf mortality decreased in the overall target group, although the letters did not produce any measurable outcomes.
Why this experiment was conducted: calf rearing necessitates a significant amount of care
Failure to ensure appropriate care for animals in dairy farming operations…
Avoiding electrical waste and promoting the manufacture of and demand for sustainable electrical products are key goals for the Federal Government. To this end, transparency for consumers is to be improved. Whether a lifespan label for electrical products can help achieve this aim was tested in an empirical study. The findings show that a lifespan label would lead to 3 out of 100 consumers opting for a more expensive product with a longer lifespan. When the lifespan was combined with information…

The impact of the energy label – and potential changes to it – on consumer understanding and on…
The study explores consumers’ understanding of the individual elements of the energy label and how the label design influences consumer choice. To this end, the study implemented two behavioural experiments to measure cognitive and behavioural responses to various label elements.

Fewer dangerous situations for cyclists: how to promote safe cycling in cities in Noord-Brabant?
Five large cities in Noord-Brabant and the provincial authorities investigated how to improve cycling safety through behavioural interventions. They placed signs and markings along cycle routes in 's-Hertogenbosch, Breda, Eindhoven, Helmond and Tilburg. Half of the interventions had an effect; the number of dangerous situations decreased.
Why this experiment was conducted: redesigning road layouts is not always possible
Six locations in towns and cities in Noord-Brabant were identified as…
Tax amnesties, a limited-time opportunity for a specified group of taxpayers to pay a defined amount of tax liabilities, are broadly used across countries because they generate short-term revenue gains. However, evidence suggest that tax amnesties fail to have long-term effects, and in some cases, they generate negative effects on compliance. With the goal of evaluating the impact of tax amnesties, this experiment relies on the behavioral principle of limited attention and redesigns the…
The Ontario Ministry of Labour, Immigration, Training and Skills Development (MLITSD) seeks to remove barriers to apprenticeship enrolment, training, and program completion as part of their mandate to increase the skilled trades workforce in the province. Amongst other strategies, these efforts have led to an expansion of existing grant schemes that aim to offset some of the costs of training and encourage training completion. In collaboration with MLITSD, the Ontario Behavioural Insights Unit…

Filing tax returns correctly and on time: Is there value in expressing thanks to citizens and…
Are people more likely to file their tax returns correctly if they receive a thank-you in advance or afterwards? Analyses show that thank-you messages have no effect on compliance behaviour.
Why this experiment was conducted: positive alternative sought
To encourage citizens' tax compliance (i.e., paying their taxes on time and correctly), it is occasional practice to emphasise the risk of checks and fines in case of non-compliance. One drawback of this deterrent method is that it can damage…
