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 data on research questions of interest to the promotion of climate action in Canada (e.g. transportation, home energy use, waste management, engagement with nature, preparedness for extreme weather,…

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…

Behavioural prompts to increase early filing of tax returns: a population-level randomised…
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…
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…

Strategies to work on the encouragement of breastfeeding with the health teams of the first level of…
The commercialization of formula milk (FM) began in Argentina at the end of the sixties. This market has grown remarkably since then, in turn, state agencies use LF as a tool to solve or combat low-weight problems in children and who for other reasons need to supplement the diet when milk is not possible exclusive breastfeeding (EBF).
The increase in LF consumption is detrimental to breastfeeding (BF). Its introduction generates a vicious circle and dependency that is difficult to reverse…
Telephone surveys were prefaced by a brief message reminding businesses that they had previously committed to participate.
30% of the requests CNAM (Primary health care institution in France) receives by phone or email could be made and treated online. In order to encourage use of online services, the CNAM solicited help from the DITP. This dematerialization would benefit the user by easing the access to services, to the administration workers by improving their work conditions and to the institutions through gains in efficience.
We chose to target a precise procedure: ordering a Carte Vitale (Health Care card) for…

Improved registration of development cooperation activities: How can an application ensure correct…
In a move aimed at improving how it registers its development cooperation activities, the Ministry of Foreign Affairs developed an application: IMPACT. This was successful in enabling budget holders to report activities more correctly: activities now have shorter names and are reported in English more often than previously. However, budget holders continue to use non-standard abbreviations.
Why this experiment was conducted: reports do not always comply with appropriate standards
The Ministry…
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,…
