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…

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…

Tax amnesties, a limited-time opportunity for a specified group of taxpayers to pay a defined amount of tax liabilities, are broadly used across countries because they generate short-term revenue gains. However, evidence suggest that tax amnesties fail to have long-term effects, and in some cases, they generate negative effects on compliance. With the goal of evaluating the impact of tax amnesties, this experiment relies on the behavioral principle of limited attention and redesigns the…

Voting is a public good in that it benefits society and is an important part of a functioning democracy. Yet, many people fail to cast their ballot on election day because the individual benefits from voting are limited. Generally, people contribute more to public goods when their behavior is made more observable to others. However, voting is inherently private: very few people observe whether you actually show up on election day. In addition, existing channels used to encourage people to vote,…

How does the presence of consumer protection affect decisions at retirement? Oxera undertook a behavioural experiment for the UK Financial Services Compensation Scheme (FSCS) to understand the role of FSCS protection—in both how consumers select their retirement income products, and whether they choose to obtain financial advice. This revealed how people behave in a realistic environment, providing insight into actual consumer behaviour and the importance of the FSCS in their decision-making.

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…

In a series of field experiments, six municipalities investigated whether a different approach in social assistance could get more people into work. The study focused on the effects of an exemption from the obligation to seek work, more intensive counselling or higher earnings disregards for additional income. A different approach can increase the number of people finding jobs. More research is needed. Why the experiments were conducted: increasing the effectiveness of the Participation…

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.

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…
