Abstract
Digitalization and the spread of artificial intelligence (AI) are transforming labor markets
and reshaping required skills. Yet, little is known about how information on AI use in
everyday work affects adolescents’ career choices. We conduct a randomized vignette-
based survey experiment with adolescent users of Switzerland’s largest pivate
apprenticeship platform. Participants are randomly assigned to view one of several
hypothetical apprenticeship descriptions.

Primary Outcomes

Primary Outcomes (end points)
Our primary outcomes of interest are stated intention to apply, word-of-mouth intentions, and interest in collecting more information about the occupation.
Primary Outcomes (explanation)
To analyze the effect participants will be asked how likely they would be to apply for the position (intention to apply) and how likely they would be to recommend the apprenticeship to a friend (word-of-mouth intention). Both outcomes will be measured on a 7-point Likert scale. The interest in collecting more information is assessed by asking participants whether they would like to learn more about the occupation (yes/no). If they answer “yes,” a link is displayed directing them to the corresponding occupation page on a job board as it would also be found by a regular search for this occupation.

Experimental Design

Experimental Design
We conduct the field experiment among German-speaking Swiss adolescents registered on the largest and most relevant private online job board for apprenticeship positions in Switzerland. The experiment will be carried out in collaboration with the respective job board. Randomization will be implemented using a cloud-based survey platform.

Experiment Characteristics

Sample size: planned number of clusters
N/A
Sample size: planned number of observations
We estimate that the final sample will comprise approximately 2,200 to 4,400 individuals. (This expectation is based on the fact that, in 2025, the job board counted 55,000 active users within our target group, all of whom will be invited to participate in the survey. Drawing on response patterns from previous surveys, we anticipate a response rate of about 5 to 10 percent. Among those who respond, earlier survey experience suggests that roughly 80 percent will complete the questionnaire in full. This anticipated range informs our expectations regarding the final number of observations.)
Sample size (or number of clusters) by treatment arms
approx. 350-730 individuals per treatment arm.
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
