Finnish Basic Income Experiment is a large scale randomized field experiment organized by the Social Insurance Institution of Finland. The experiment began in January 2017 and it includes 2,000 unemployed workers receiving basic income. The basic income is 560 euros per month and it is paid unconditionally for two years. We will evaluate the effect of this basic income model using register-based data. Our main objective is to estimate the effect of this basic income model on labor supply. Our secondary outcomes include earnings, income, participation in labor market programs, and health indicators.

Experimental Details
The treatment group receives the unconditional basic income for two years. The basic income is a monthly benefit of 560 euros that is not affected by the level of employment. The basic income replaces minimum unemployment benefits and it is paid together with other social benefits. As the income tax schedule remains unaffected, the monetary incentives to work increase strongly. Participation in the experiment is mandatory and governed by a law.

Experimental Design
Experimental Design
The target population of the experiment consists of individuals who are 25 - 58 years of age and received the minimum unemployment benefits in November 2016. The Social Insurance Institution of Finland randomized 2,000 individuals into treatment group in December 2017. The rest of the individuals in the target population can be used as a control group.
The follow-up of the experiment will be based on administrative register data. Different registers provide a large set of background characteristics and various outcome variables. Register data are complemented by a survey carried out in October 2018.

Experiment Characteristics
Sample size: planned number of clusters
No clusters, simple random sampling
Sample size: planned number of observations
The target population includes over 100,000 unemployed individuals.
Sample size (or number of clusters) by treatment arms
The treatment group includes 2,000 individuals receiving basic income.
The control group is defined based on register data and the number of individuals is very large (>100,000).
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
Based on historical data on unemployed individuals from 2011 to 2013, we estimate the minimum detectable effect to be around 11% increase in employment days with 80% power and 5% significance level.
