The Environmental Habits and Values Survey (2020) aims to explore the values, opinions, attitudes and behaviour of Barcelona's citizens in relation to the environment, sustainability and climate change. This study was launched in 2000 and is carried out every four years. This year, 2024, the questions have been revised and the project is on-going.
The series has a dual value: on the one hand, it provides a snapshot of the values and attitudes of Barcelona residents at the time the survey is…

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…
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…
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…
As rewards increasingly become an instrument used by policymakers, it is important to find a reward mechanism that does not crowd out intrinsic motivation, is long lasting, and has positive spillover effects on third parties. A policy innovation introduced by the Municipality of Santa Fe (Argentina) allowed us to evaluate different mechanisms for rewarding tax compliance – participation in a lottery (financial motive), public recognition (moral channel), and provision of a visible and durable…

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…

Farmers and the new green architecture of the EU common agricultural policy: a behavioural…
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.
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…

Encouraging the wearing of face masks in hospitality venues: how to ensure guests wear face masks in…
Due to the COVID-19 pandemic, guests were required to wear face masks on entering and while moving inside hospitality venues. To promote this behaviour, self-persuasion and salience techniques were used in this experiment - with notable success. Following the announced relaxation of face mask requirements, there was a decrease in face mask usage, although this was significantly less in hospitality venues that saw interventions than in venues that did not experience interventions.
Why this…

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…
