In a randomised trial we sent reminder letters to self-employed entrepreneurs about their upcoming VAT filing date. Previously it was not common practice for the Hungarian tax administration to send large scale reminders before the due date.

Electricity Information to Fit the Bill: Redesigning electricity bills to support consumer…
Electricity bills are a key way to inform people about their plan and usage, but bills can be confusing and are not really useful to help people navigate the electricity market. BETA and the Department of the Environment and Energy ran a trial to test the impact of bill design on people’s confidence in their ability to look for a better offer and intention to do so. We drew on behavioural insights to design and test six electricity bills. We focussed on simplifying bill design to draw…

Website Verbeterjehuis.nl helps homeowners choose the right sustainability measures: which…
This online experiment tested various ways in which sustainability measures for homeowners are presented on the website verbeterjehuis.nl, ‘improve your home’. The variant emphasising that the sustainability measures are 'recommended for your personal situation' proved to be most effective. This addition acts as an incentive to homeowners to install roof insulation or adopt other sustainability measures.

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…
BETA partnered with the Australian Energy Regulator to apply behavioural insights to the design of energy bills. We conducted a literature review to identify key research questions. We used 2 online samples involving over 6,300 and 7,800 Australians, respectively to a survey and 6 randomised controlled trials (survey experiments). They investigated the possibility of cognitive overload, and the impact of various bill components on comprehension and intentions.
Installation of large, moveable trash containers and trash cans in convenient locations made disposal of large trash bags and litter easier for residents of New York City public housing. A package of indoor and outdoor posters informed people of the new policy and encouraged them to use the new infrastructure.

Less waste placed next to underground containers: is there a reduction in the amount of waste left…
The Municipality of Dordrecht organised a competition titled The Cleanest Neighbourhood in Dordrecht. The aim was to get residents to place less rubbish next to underground waste containers. As a result of the experiment, the amount of waste left next to bins decreased and a new social norm was established.
Why this experiment was conducted: rubbish left next to waste containers
Bin liners and other bags containing residual and larger waste left next to underground containers rank amongst the…

More conscious student borrowing behaviour: How can excessive loan amounts be avoided after the…
Are there ways to limit the accrual of excessive loan amounts by students? A letter sent to students with student loans who have received a supplementary grant increases the likelihood of them reducing their loan amounts. This increased likelihood translates to an annual average decrease of over € 150 in loan amounts for students receiving both a supplementary grant and a loan.
Why this experiment was conducted: award of supplementary grant sometimes has little or no impact on loan…

Empirical testing of the impact on consumer choice resulting from differences in the composition of…
Differences in the composition of seemingly identical branded food products (DC-SIP) has been a source of growing concern in the EU in recent years. This was particularly the case after tests conducted in several Member States (MS) confirmed the presence of differences in composition of some branded food products sold across different Member States. This report aims to contribute to the existing studies by verifying whether the presence of DC-SIP influences consumer preferences and willingness…
The problem
Missed appointments are a significant cost to the health care system, and patients who do not attend appointments miss out on valuable care.
What we did
We partnered with the Department of Health and Human Services and several health services to improve patient communications as part of a new Communications Toolkit for health services.
To understand what works, we designed a range of behaviourally-informed SMS reminders and letters to reduce the number of patients who do not attend…
