In Germany there are significant gaps in measles vaccination which lead to repeated outbreaks of the disease. Vaccinations do more than just protect the recipient against infection. They also protect people who cannot be vaccinated, for example infants or people with certain chronic illnesses. However, many adults do not know that they are not completely vaccinated against measles. In order to close this information and vaccination gap, wirksam regieren compared various possible ways to provide…
Surveys give people an opportunity to be heard and provide government with vital information about the impact of its services. BETA partnered with Department of Social Services (DSS) to encourage more people to complete the Data Exchange survey.
Data Exchange is new report platform developed by DSS to enable the collection of meaningful data about service delivery outcomes from organisations receiving community grants. As part of this platform, a client survey enables clients to self-report on…
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.
In the study, the effectiveness of four reminder messages was evaluated through an online laboratory experiment involving 2,963 participants. The content of these messages was designed based on evidence from behavioural sciences, and their effect was contrasted with that of a simple, brief, and direct message (control message). The impact of the reminders was measured through four outcome variables: the action participants declared they would take after receiving the message, understanding and…
The Environment Act 1986 established the Ministry for the Environment (MfE), which is the primary adviser of the New Zealand Government on environmental matters. The purpose statement for the MfE is “A flourishing environment for every generation – He taiao tōnui mō ngā reanga katoa [te reo version, the indigenous language of the Māori people].
MfE is actively engaged in reducing waste across the country, as illustrated by the recent Aotearoa New Zealand Waste Strategy. To lead by…
This project leverages an online survey experiment among federal employees involved in the process of translating information and evidence about a program into actionable policies and programs. The experiment’s primary aim is to test ways of presenting information to improve sensitivity to impact-relevant information about a program. The impact-relevant features tested are: the number of people impacted, the intermediate or final outcomes and the persistence of effects. In addition, the…

In Haiti, more than 96 percent of the population is exposed to two or more natural hazards in theirlifetime. The human and economic impacts of these hazards, including hurricanes, floods, earthquakes, and landslides, have been severe. Between 1961 and 2012, the country experienced more than 180 disasters, causing the death of more than 240,000 people. Many disaster-related fatalities are preventable if people evacuate to a safer place in a timely fashion. However,in Haiti, due to a variety of…
In partnership with Environment and Climate Change Canada (ECCC) and Natural Resources Canada (NRCan), the Impact and Innovation Unit (IIU) has launched a multi-year program of research on climate change. The Program of Applied Research on Climate Action in Canada (PARCA Canada) combines behavioural science (BeSci) insights and methods with robust policy analysis to promote climate action. One of the main areas of focus involves the launch of a longitudinal survey that will, over time, collect…
We seek to increase voluntary appearances for people with outstanding Warrants to Arrest (WTA) through reminder phone calls from Māori Wardens and Police. This Auckland-based project follows a proof-of-concept trial in the Eastern District, in which Māori Wardens made phone calls to people with outstanding WTAs and we compared voluntary appearances for those who were reached via phone to those who were not.
While this first trial showed indicative evidence that phone calls may be effective,…
