Despite the overwhelming medical evidence on the protection offered by the second, third and fourth doses of the Covid-19 vaccine, the acceptance of these doses remains low despite the existing supply. The problem is likely because there are currently no reminders in the province of Chaco, Argentina. This makes it difficult for residents to know if they are eligible for the next dose of the COVID-19 vaccine and where to access it. Booster vaccination is associated with a lower risk of mortality…

Due to the COVID-19 pandemic, guests were required to wear face masks on entering and while moving inside hospitality venues. To promote this behaviour, self-persuasion and salience techniques were used in this experiment - with notable success. Following the announced relaxation of face mask requirements, there was a decrease in face mask usage, although this was significantly less in hospitality venues that saw interventions than in venues that did not experience interventions. Why this…

Electricity bills are a key way to inform people about their plan and usage, but bills can be confusing and are not really useful to help people navigate the electricity market. BETA and the Department of the Environment and Energy ran a trial to test the impact of bill design on people’s confidence in their ability to look for a better offer and intention to do so. We drew on behavioural insights to design and test six electricity bills. We focussed on simplifying bill design to draw…

To promote college access and affordability, education tax credits help with the cost of college by reducing the amount of tax owed. The most generous Federal higher education tax credit, the American opportunity tax credit (AOTC), is a maximum annual credit of $2,500 per eligible student. Yet, many eligible students (or their families) do not claim the credit. Among eligible students, national estimates indicate that 46 percent of independent students and 56 percent of dependent students take…

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…
