Teachers in a summer school program for high school students provided brief, individualized, messages for parents with information about their child’s performance and behavior in school on a weekly basis.
IMPACT
Providing parents with individualized messages increased the probability a student earned credit for each class by 6.5 percentage points – a 41% reduction in failure rates.
In connection with the 2022 county elections, an experiment was conducted in Finland for the first time to examine the impact of text message reminders on the voting turnout of young people. In the experiment, young people (aged 18 to 29) were messaged twice about the schedule of the county elections and their right to vote. The aim of the study was to find out whether a text message reminder increases voting turnout. The experiment was carried out in cooperation with the Ministry of Justice and…

Designing Behaviorally Informed Health Interventions: Adherence to Micronutrient Treatment in El…
This study tested a behavioral intervention aiming to help reduce the prevalence of anemia in children in El Salvador. It first describes a traditional micronutrient distribution program for rural households. The analysis shows that although implementation was relatively successful, and take-up high, adherence to the full treatment of micronutrients was much lower. To explain this gap, the analysis employs a design methodology based on the “caregiver journey.” This methodology is a…

Reduced calf mortality at dairy farms: how can dairy farmers be encouraged to take proper care of…
To reduce calf mortality rates, the Netherlands Food and Consumer Product Safety Authority (NVWA) developed various letters for distribution amongst three subgroups of dairy farmers. The impact measurement shows that calf mortality decreased in the overall target group, although the letters did not produce any measurable outcomes.
Why this experiment was conducted: calf rearing necessitates a significant amount of care
Failure to ensure appropriate care for animals in dairy farming operations…
Normative messages have been shown to increase intention to do physical activity. Positive normative message say that most people like you are physically active. Negative normative message say that most people like you are NOT physically active. The study traces how “positive” and “negative” normative messages influence physical activity intention.
BETA is working with the Department of Social Services to evaluate the effectiveness of various behaviourally informed approaches on increasing workplace giving.
Landfills are a major contributor to methane emissions in the United States. By diverting organic waste from landfills, composting may reduce the global warming effects caused by methane. However, only a small proportion of compostable food is currently composted. This is because of barriers to composting that are both structural (lack of public composting infrastructure) and psychological (insufficient knowledge about and interest in composting among prospective users).
We set out to develop a…

Behavioural prompts to increase early filing of tax returns: a population-level randomised…
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…
