Prior work
This trial does not extend or rely on any prior RCTs.
Low-educated adults are underrepresented in adult education. At the same time, the current high-paced technological change shapes and stimulates demand for a labor force capable of constantly updating its skill set, which can result in a wedge between labor supply and demand if the supplied and demanded skill profiles grow apart. In a large-scale field experiment, we study if a financial incentive in the form of a scholarship increases enrollment in education among skilled adult workers.

Primary Outcomes

Primary Outcomes (end points)
Education enrollment
Primary Outcomes (explanation)
We will construct the dummy variable Enrolled that measures enrollment in education. Specifically, we base this on the variable for ongoing education from Statistics Norway called “igang 2022”, which records if a person is registered in education in October of any given year, in our case, in October 2022 (2021 for the pilot sample).

Secondary Outcomes

Secondary Outcomes (explanation)

Experimental Design

Experimental Design
Scholarship group: receives an offer of an educational scholarship if they enroll in education during the following study year (August-June) and information about what possibilities exist regarding further education.
Information group: receives the same information regarding educational opportunities and general funding possibilities without the specific scholarship offer.
Control group: not contacted.
Experimental Design Details
Randomization Method
Randomization done by computer script.
Randomization Unit
Was the treatment clustered?

Experiment Characteristics

Sample size: planned number of clusters
No clusters.
Sample size: planned number of observations
292 002 individuals in main experiment
Sample size (or number of clusters) by treatment arms
Scholarship group: 61 800 individuals
Information group: 169 950 individuals
Control group: 67 252 individuals
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
To test the hypothesis that a scholarship offer affects the proportion who enrolls in education, using a p-value of 0.05 and 80% power, we have a minimum detectable effect size (MDE) of 0.00027.
