Experimental Design

Experimental Design
The study will be conducted through an online survey. Participants are third-year undergraduate students at a private university located in Tokyo. All third-year students are invited to participate in the survey, and only those who wish to do so take part in the online survey. First, participants will provide information on their personal attributes and student life, including their majors, part-time job experience, and participation in job-hunting activities or internships. Second, participants will answer questions about their attitudes toward gender issues and their preferences regarding risk-taking and time-discounting. Finally, participants will be presented with two hypothetical job postings and asked to indicate which one they prefer.

Experiment Characteristics

Sample size: planned number of clusters
N/A
Sample size: planned number of observations
Number of students invited to participate in the survey: 1,170. In total, we aim to collect 11,700 individual-job pair level observations (= 1,170 × 5 × 2) across randomized sets of job attributes.
Sample size (or number of clusters) by treatment arms
Each participant completes two parts of the survey experiment.
In Part 1, all participants are shown five pairs of hypothetical job postings and asked to choose one from each pair.
In Part 2, they are again shown five new pairs of job postings and asked to make selections in the same way.
Thus, each participant makes 10 choices in total (5 in Part 1 and 5 in Part 2).
The planned total number of participants is 1,170 (individual-level randomization).
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
