Why this experiment was conducted: scepticism about second-hand clothes
The clothing industry is a major polluter, and the second-hand market is an important alternative to new clothes. While more and more Dutch consumers are turning to pre-owned clothing, a large group remains sceptical. According to a target group study conducted in 2020, they wonder whether they will be able to find a suitable second-hand item, and whether it is hygienic. The best way to overcome this scepticism is to create…

Water scarcity remains common in Brazil, especially in the Recife Metropolitan Region (RMR) in the State of Pernambuco. The RMR is subject to particularly high levels of non-revenue water—which occur when high volumes of water produced do not generate revenue for the supplier. While some losses may be due to structural and operational inefficiencies such as leaky pipes, clients also play a key role by defaulting on their water payments or installing bypasses to consume water free of charge.…

Stabilization of blood supply and demand for the National Transfusion Service of the Slovak Republic
Analysis of the preferences of current blood donors and development of a strategy for launching a behavioral blood donor registry.
Challenge
Students in low-income districts are less likely to sign up to take the Gifted and Talented (G&T) admissions test than their peers in higher-income districts. As a result, fewer students from low-income districts test into and attend G&T programs that could improve educational outcomes and provide meaningful opportunities. To the extent that the city may use sign-up rates as an indicator of demand, and thus where additional G&T programs should be located, low sign-up rates can mean…
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 data 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,…
It’s the end of April in Poland. While everyone
is happy the harsh winter weather is finally getting
milder, the Polish Tax Authority is worried because
62% of the country failed to pay their taxes on time.
Over the past decade, the use of behavioral principles
by tax administrations in different countries has been
gaining ground. Given the country’s tax compliance
rate, Polish authorities and the World Bank tested the
use of behaviorally informed letters to late taxpayers
in order to…
How does information on the job market affect the expectations and preferences of
pupils in pre-vocational education?
A large online platform for career development and career counselling
provided pupils who were attending pre-vocational colleges with
information on the career prospects of professions in which they are
interested. This information resulted in pupils revising their expectations,
and made them more likely to aim for jobs with better career prospects.
Challenge
Kosovo is the youngest country in Europe and faces the challenges of creating a government and setting up systems to generate funds needed to invest and develop. In 2018, only 47% of taxpayers made even a partial payment towards their due taxes. The consequences of low tax compliance and late repayment are two-fold. Individuals accumulate debt, interest, and fines from nonpayment which also prevents them from purchasing homes or registering vehicles until these debts are paid. On the…

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…

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…
