The purpose of this survey is to better understand Canadians’ perceptions, knowledge and decision-making related to home energy labels and to explore different design features and information presentations that may drive energy-efficient choices.
The Government of Canada has announced plans to achieve 60% of personal vehicle sales to be comprised of zero-emissions vehicles(ZEV) by 2030, and 100% by 2025. While ZEVs have growing momentum among Canadians, sales penetration remains low compared to stated targets. In partnership with Natural Resources Canada, the Impact and Innovation Unit (IIU) are conducting this research to better understand the drivers and barriers to ZEV adoption among Canadians, and empirically test a selection of…

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…
Building on BETA’s work with the Australian Financial Security Authority (AFSA) on applying behaviour science to the Personal Property Securities Register, BETA and AFSA are evaluating whether select recommendations make the registration process easier and if they lead to more accurate registrations.
We seek to increase voluntary appearances for people with outstanding Warrants to Arrest (WTA) through reminder phone calls from Māori Wardens and Police. This Auckland-based project follows a proof-of-concept trial in the Eastern District, in which Māori Wardens made phone calls to people with outstanding WTAs and we compared voluntary appearances for those who were reached via phone to those who were not.
While this first trial showed indicative evidence that phone calls may be effective,…

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.
Using sustainable transportation alternatives can often be hindered by car dependence (Haustein, 2021). Within the context of Santa Monica, for example, approximately 75% of Santa Monica residents choose single occupancy vehicle (SOV) commutes to work, and over 50% of households own more than one vehicle (Data USA, n.d.). More generally, vehicle transportation accounts for 62% of greenhouse gas emissions in the city, making it the largest emissions contributor (Johnstone, 2021).
However,…

Helping social assistance recipients in finding work: Does a different approach lead to more people…
In a series of field experiments, six municipalities investigated whether a different approach in social assistance could get more people into work. The study focused on the effects of an exemption from the obligation to seek work, more intensive counselling or higher earnings disregards for additional income. A different approach can increase the number of people finding jobs. More research is needed.
Why the experiments were conducted: increasing the effectiveness of the Participation…
The NYC Behavioral Design Team provided an additional reminder to Supplemental Nutrition Assistance Program (SNAP) clients that they would lose their benefits if they did not complete the SNAP recertification process. Highlighting the consequences and including attention-grabbing icons made this NYC BDT supplemental SNAP recertification notice more salient and actionable for clients.
BETA partnered with AFSA on two projects to determine how to best communicate about the consequences of bankruptcy.
In the first project, over 6,500 Australians completed one of six educational tools online that explain the consequences of bankruptcy and then assessed their levels of understanding. A pop-quiz and video were most effective, improving people’s understanding by 27 percentage points above the group that saw no educational tool.
In the second project, we introduced five additional…
