This behavioural experiment with farmers assessed the effect of two policy features of the new green architecture of the EU common agricultural policy on the adoption of environmentally friendly practices: (1) increasing mandatory adoption and (2) shifting budget to voluntary schemes, by decreasing direct payments.
In a pre-registered experiment, we tested whether expert endorsement increases the effectiveness of debunking messages about COVID-19 vaccines. We monitored a sample of 2,277 people in Italy through a longitudinal study along the salient phases of the vaccination campaign. Participants received a series of messages endorsed by either medical researchers (experimental group) or by generic others (control). In order to minimise demand effects, we collected participants’ responses always at ten…
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…
We all know that if a 13-year-old has his mind set on
something, it is quite difficult to try to change it. This
is exactly the type of challenge that the Ministry of
Education in Peru is approaching with students in
public schools and high schools, targeting those from
low-income households in particular.
Teenagers often have pre-conceived ideas about their
own intelligence, which influences how they react to
academic challenges. If a student thinks he is not smart
enough, he believes there is…

Effective position of call-to-action: Is the response rate higher if the call-to-action appears the…
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…
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.

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…

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…
The Program of Applied Research on Climate Action in Canada (PARCA Canada) combines behavioural science (BeSci) insights and methods with robust policy analysis to promote climate action. One of the main areas of focus involves collecting data over time on research questions of interest to the promotion of climate action in Canada (e.g. transportation, home energy use, waste management, engagement with nature, preparedness for extreme weather, disaster recovery, etc.) using a large and…
In partnership with Environment and Climate Change Canada (ECCC) and Natural Resources Canada (NRCan), the Impact and Innovation Unit (IIU) has launched a multi-year program of research on climate change. The Program of Applied Research on Climate Action in Canada (PARCA Canada) combines behavioural science (BeSci) insights and methods with robust policy analysis to promote climate action. One of the main areas of focus involves the launch of a longitudinal survey that will, over time, collect…
