Making a nation-wide randomized field experiment: - Lessons from the Finnish basic income trial

The original goal of the Finnish experiment of 2017 and 2018 was to try to get some evidence on how a new social policy instrument mimicking a basic income would work and what kind of behavioral consequences it would have. The realized experiment was restricted to people aged 25–58 already receiving a labor market subsidy or unemployment allowance and a total of 2,000 participants were randomly selected to receive a basic income payment of €560 per month.
