In Indonesia, as in other countries, a large proportion of tax returns are filed at the last minute. In a population-wide randomised controlled trial (n = 11,157,069), we evaluated the impact of behavioural email prompts on the proportion of annual tax returns filed at least two weeks before the deadline; and overall filing rate. In two control conditions, taxpayers either received no email or an email used in prior years, emphasising regulatory information. The five treatments informed by…
To support building the pipeline of skilled workers in Ontario, the Ministry of Labour, Immigration, Training and Skills Development (MLITSD) introduced the Skilled Trades Strategy (STS) in 2020 which aims to modernize the skilled trades and apprenticeship system by breaking the stigma and attracting more young people to the skilled trades, simplifying the system, and encouraging employer participation. In collaboration with MLITSD, the Ontario Behavioural Insights Unit (BIU) plans to run a…

Full price information for consumers: What effect does the way prices are displayed have on online…
The Netherlands Authority for Consumers & Markets (ACM) conducted an experiment to investigate the effect of incomplete prices when booking a holiday home. Websites that display incomplete prices cause greater uncertainty, make choosing more difficult, undermine trust and give the feeling of deception compared to websites displaying transparent prices.
Why this experiment was conducted: unclear picture of actual costs
In 2021, the ACM conducted a study into effective transparency. The aim was…
BETA partnered with the Department of Social Services to determine the effect of behaviourally-informed activity statements on gambling behaviour in a simulated game. We tested two activity statement prototypes and found participants who saw the activity statements bet less than those who did not. Showing participants clear and easy-to-understand information about their gambling activities empowered them to make informed decisions about how much to bet. This project was conducted under Measure 7…

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…
emand within the Child Protection system has grown significantly over the last decade.
The education sector is a particularly important stakeholder. Teachers and other school staff interact with children regularly and are often the first to notice if a child is at risk or needs support.
This project sought to better understand the decision making process of professionals from the education sector, Child Protection Intake and Child FIRST lead agencies for identification of whether a child is…

Reporting a change in income to Benefits Unit: How to ensure that more people comply with their…
'Returning to employment? Don't forget about your benefits!' When individuals receiving benefits return to employment having been registered as unemployed, it is important that they report the change in their income to the Benefits Unit on time, to avoid repayment demands. Why do individuals not comply with this notification requirement? And what interventions could improve compliance? A revised letter from the UWV Employee Insurance Agency and an additional page on the Benefits Unit website…
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…
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…

IMPACT
The average aid award for students receiving both redesigned emails rose by $150.28 per student for the Spring semester compared with students who received neither email, with a total…
