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…

Increasing consumer engagement in the annuities market: can prompts raise shopping around?
In June 2016, Oxera and the Nuffield Centre for Experimental Social Sciences (CESS) published the results of an experiment testing the effectiveness of different ‘prompts’ in encouraging consumers to shop around. The study, commissioned by the UK Financial Conduct Authority (FCA), found that personalised messages were the most effective in stimulating product comparisons, while generic messaging appealing to social norms also had a significant impact.
Behaviorally informed messages have had demonstrated success in increasing tax compliance in multiple regional settings. In Indonesia, which has the largest economy in Southeast Asia, a trial from the Directorate General of Taxes (DGT) and World Bank teams looked at whether behaviorally informed messages and materials can impact tax compliance and payment rates among small and medium enterprises (SMEs). The results showed, to get delinquent firms to pay their taxes, information is not enough -…

Levelling the playing field in police recruitment: Evidence from a field experiment on test…
How to increase diversity in the police is an unanswered question that has received significant political and media attention. One area of intervention is the recruitment process itself. This study reports the results of a randomized controlled trial (RCT) in a police force that was experiencing a disproportionate drop in minority applicants during one particular test. Drawing on insights from the literatures on stereotype threat, belonging uncertainty and values affirmation exercises, we…

Making sure that young people get vaccinated against HPV: How do you encourage both boys and girls…
A campaign was launched to encourage young people to get the catch-up vaccination against Human Papillomavirus (HPV). The campaign succeeded in promoting discussion and increased awareness of HPV as well as persuading young people to get vaccinated.
Why this experiment was conducted: provide boys and girls with a vaccine they might not have received
In 2022 and 2023, boys were invited for the first time and girls were invited again to get vaccinated against the Human Papillomavirus (HPV). HPV…
Using a place-based approach and working with profiled local communities in Coventry, we prototype and test a new experimental methodology with elements of design thinking to better understand barriers to engagement with retrofit measures designed to reduce household carbon emissions and alleviate fuel poverty. We partner with Coventry City Council, a local school and artists to deliver a pilot scheme in the Radford area of Coventry and aim in future to expand the project to additional areas…

Promising circular business models: what options for a sustainable purchase are acceptable to…
A circular business model promotes reuse of products and materials. A case in point is a model where consumers return their jeans to the manufacturer after use. Which circular business model characteristics are consumers willing to accept right now, and what do they refuse? Acceptance of these models seems to increase if companies offer effective or appealing option combinations, such as monthly payment schedules and discounted returns.
Why this experiment was conducted: to promote the circular…

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…
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…
Challenge
At San Francisco State University, 18% of students drop out by the end of their first year, mostly for reasons unrelated to their academic achievements. The goal was to increase the number of first-year college students returning for their second year.
Design
To help first-year students understand that the challenges they faced were neither unique to them nor evidence of personal failure, all incoming first-year students at SF State were asked to watch a three-minute video in which…
