Tax delinquencies are a major problem for most tax administrations in the world. In Colombia, the National Accountant Office estimated the total outstanding debt to the National Tax Agency at $2.5 billion, which represents about 20 percent of estimated total tax evasion in 2014. Finding ways to reduce tax delinquencies is critical for both fiscal and equity considerations. A previous study compared messages about due liabilities delivered through three channels (letter, email, or…

Working more hours to combat teacher shortages: How can teachers be motivated to increase their work…
In a vignette survey, teachers in primary, secondary and post-secondary vocational education were asked whether they would like to work more hours − with and without incentives. The survey shows that their willingness to do so can be increased to varying degrees by offering them bonuses, additional employee benefits and a combination of both.
Why this experiment was conducted: teacher shortages
The government has identified significant staff shortages in primary and secondary education. It is…
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…

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…
Government agencies around the world struggle to retain frontline workers, as high job demands and low job resources contribute to persistently high rates of employee burnout. Although four decades of research have documented the predictors and potential costs of frontline worker burnout, we have limited causal evidence on strategies that reduce it. In this article, we report on a multicity field experiment (n = 536) aimed at increasing perceived social support and affirming belonging among 911…
The Adult Migrant English Program (AMEP) is a government-funded program for all permanent visa holders and some temporary visa holders who have less than a vocational level of English. Not all people who are eligible for the AMEP participate in it. The Department of Home Affairs commissioned BETA to evaluate the effectiveness of communication in participants’ home languages on increasing participation in the AMEP.
Trial 1: We will send text messages to speakers of Mandarin, Cantonese,…

The Impact of Behaviorally Informed Communications on Uptake of a Cover Crop Cost-share Program
ideas24 partnered with the Practical Farmers of Iowa (PFI) to better understand the behavioral barriers preventing corn and soybean farmers from adopting cover crops and enrolling in PFI's cover-crop cost-share program. Using what we learned from administrative data, farmer interviews and direct feedback during user-testing, we then jointly designed behaviorally informed communication interventions, which included mailers as well as a farmer referral campaign. To evaluate the potential impact of…

More conscious student borrowing behaviour: How can excessive loan amounts be avoided after the…
Are there ways to limit the accrual of excessive loan amounts by students? A letter sent to students with student loans who have received a supplementary grant increases the likelihood of them reducing their loan amounts. This increased likelihood translates to an annual average decrease of over € 150 in loan amounts for students receiving both a supplementary grant and a loan.
Why this experiment was conducted: award of supplementary grant sometimes has little or no impact on loan…

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…
