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…
Testing Labelling Dimensions for Chemicals in Products
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…
Challenge
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…

This study presents the results of a field experiment aimed at attracting more and different people to apply to a police force by varying job…

Can Visual Cues to Portion Size Reduce the Number of Portions of Consumed? Two Randomized Controlled…
Methods
Two preregistered randomized controlled trials (N = 253 and N = 674) measured consumption in a lab and the home environment. Cues were salient, labeled stripes that demarcated single portions. Participants were randomized to cue condition or control. Consumption was measured without awareness.
Results
The main preregistered effect of the visual cue was not statistically significant. There was some variation by subgroup. In Study 1, men were more likely to eat the whole can of potato…
All employees working in Australia are entitled to a minimum wage and minimum standards of employment. The underpayment of wages and entitlements is a serious social and economic issue which affects workers, businesses and the community.
The Fair Work Ombudsman (FWO) uses audits to keep businesses on track—and we set out to see if these audits could be even more effective. The result was a win-win for workers, businesses and the community. Employees were $900 better off on average, instances…

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…
