To reduce the speed of motor vehicles on the Yarze highway, Nudge Lebanon, in collaboration with the Traffic Management Centre (TMC), placed a salient image of overlooking eyes, coupled with a message informing drivers that their speed was being monitored on a Variable Message Sign (VMS). Vehicles in treatment time slots, with speeds above 100km/h reduced their speed by around 11.5% compared to similar vehicles in the control group. Moreover, compared to the control group, the treatment was more…

Social Multipliers at Work: Improving Children’s Outcomes Through Aspirations and Role Models
Every year, governments spend large amounts
of resources on development programs that aim
to change poor households’ behaviors and attitudes
toward investment in the education, health, and
nutrition of their children as a way to end the cycle
of poverty. One key mechanism that can achieve this
is working to raise aspirations. But how do you do
that in practice?
In this project, together with Karen Macours of the
Paris School of Economics and the Ministry of Family
in Nicaragua, we find that…

Combining Incentives with Narratives: Online-Field Experiment with Tesco to Reduce Plastic Bag Use
The pervasive use of single-use plastic bags presents a growing environmental challenge globally. Despite legislative efforts, such as the mandatory 5p bag-charge introduced in England in October 2015, the problem persists. The issue took on renewed urgency in the wake of the Covid-19 pandemic, which has seen a regression in consumer habits towards increased use of single-use plastics, driven by health and safety concerns (Adyel, 2020).
While traditional economic theory suggests that incentives…
Previous research by the Program of Applied Research on Climate Action and the Environment (PARCA) team has found that Canadians generally display poor understanding of the relative impacts of different pro-climate actions and have gaps in their understanding of climate change. Following up on these findings, a randomized controlled survey-experiment was conducted in December 2023 to test the impact of several behaviourally-informed interventions on climate literacy outcomes. Results suggested…
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…

Correcting Misperceptions About Trends and Norms to Address Weak Collective Action – Experimental…
Finding ways to encourage collective action in contexts where only a minority adopts the desired behaviour is central to solving many of today's global environmental problems. We study how correcting people's beliefs about social norms and behavioural trends encourages collective action in a setting where the desired behaviour is not yet prevalent. In a field experiment, we test whether low sign-up rates for a municipal recycling program in urban Peru can be increased by providing information…
In Haiti, more than 96 percent of the population is exposed to two or more natural hazards in theirlifetime. The human and economic impacts of these hazards, including hurricanes, floods, earthquakes, and landslides, have been severe. Between 1961 and 2012, the country experienced more than 180 disasters, causing the death of more than 240,000 people. Many disaster-related fatalities are preventable if people evacuate to a safer place in a timely fashion. However,in Haiti, due to a variety of…
PROJECT SUMMARY
To increase uptake of flu vaccines and maintain a healthy workforce during the 2016-17 flu season, New York City’s Behavioral Design Team (NYC BDT) partnered with WorkWell NYC to design behaviorally informed emails to encourage New York City employees to visit a worksite flu clinic. One version of the redesigned email used the strategy of “enhanced active choice,” whereby employees were prompted to make a choice that had a clear right answer.

Designing Behaviorally Informed Health Interventions: Adherence to Micronutrient Treatment in El…
This study tested a behavioral intervention aiming to help reduce the prevalence of anemia in children in El Salvador. It first describes a traditional micronutrient distribution program for rural households. The analysis shows that although implementation was relatively successful, and take-up high, adherence to the full treatment of micronutrients was much lower. To explain this gap, the analysis employs a design methodology based on the “caregiver journey.” This methodology is a…

Behavioural study on the pan-European Personal Pension Product (PEPP) information documents
The overall purpose of the study is to facilitate and execute graphic design work and consumer testing regarding the pan-European Personal Pension Product (PEPP) Key Information Document (KID) and Benefit Statement (BS) in three Member States. We will use mix behavioural methods to understand relevant behavioural biases, and why consumers find certain aspects of information related to pension products difficult to understand, and how to overcome those difficulties.
