PROJECT SUMMARY
ideas42 and Busara Center for Behavioral Economics worked with a major bank and telecommunications company in Nigeria to send behaviorally-informed SMS messages to customers to increase their use of mobile bank accounts.
IMPACT
Effects varied by message and audience; notably, injunctive norm messages led to a 45 percent increase in the number of clients making deposits among females with active accounts, from 0.82% to 1.81%.

Online experiment tested two novel public health messages on social distancing.
•Messages focused on potential to infect vulnerable people or many people.
•Participants (N = 500) randomized to see control or (one of two) treatment posters.
•Behavioral intentions and acceptability judgements of behaviors measured later.
•Both posters increased caution with respect to social distancing.
Regulators require lenders to display a subset of credit card features in summary tables before customers finalize a credit card choice. Some jurisdictions require some features to be displayed more prominently than others to help ensure that consumers are made aware of them. This approach could lead to untoward effects on choice, such that relevant but nonprominent product features do not factor in as significantly. To test this possibility, we instructed a random sample of 1615 adults to…
Behavioural Additionality & Spillovers in the R&DTI
Background
This project aimed to understand the behavioural additionality effects of the R&DTI via a series of user interviews with companies currently engaged in R&D (including those participating and not participating in the R&DTI). Behavioural additionality goes beyond the traditional view of R&D additionality, which typically focuses on quantitative increases in inputs and outputs. Instead, behavioural additionality considers wider,…
BI Project
Filing tax returns correctly and on time: Is there value in expressing thanks to citizens and…
Are people more likely to file their tax returns correctly if they receive a thank-you in advance or afterwards? Analyses show that thank-you messages have no effect on compliance behaviour.
Why this experiment was conducted: positive alternative sought
To encourage citizens' tax compliance (i.e., paying their taxes on time and correctly), it is occasional practice to emphasise the risk of checks and fines in case of non-compliance. One drawback of this deterrent method is that it can damage…
BI Project
Preparedness skills, sense of community and clear recommendations for action increase crisis…
The COVID-19 pandemic, the war in Ukraine, and other social and global political crises and incidents have increased the need to understand the mental resilience, preparedness, agency and sense of community of Finns in various crises and disruptions. This memorandum presents information related to these topics collected via the Citizens’ Pulse survey and citizen interviews commissioned by the Prime Minister’s Office in March and April 2022.
PROJECT SUMMARY
Students were sent two redesigned emails during the course selection process: a pre-registration email that laid out instructions and procedures for registration, and a post-registration email that notified students if any of their upcoming courses did not fit financial aid requirements.
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…
BI Project
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…
BI Project
Generating more enthusiasm for teacher training programmes: How to get students more interested in…
In this experiment, various emails were sent to students in senior general secondary education (HAVO) and preuniversity education (VWO) to inform them about open days of teacher training programmes. The subject line that most caught their attention was ‘Are you looking for job security, challenge and a wide range of career opportunities?’ as well as a subject line in which a role model was introduced. Where emails mention teachers' starting salaries, students most often click links to more…
BI Project
Can interventions in supermarkets reduce household food waste? A randomised controlled trial of…
The study was conducted in collaboration with eight supermarkets from two of the largest Swedish supermarket chains. The stores provided the natural environment in which to conduct an experiment using real shoppers and real purchases, without shoppers being aware of the study. Four different interventions (different price displays) were designed, based on insights from behavioural science. These signs were tested in a randomised controlled study for two common and perishable vegetables –…
