Trial Title The effect of uncertainty on search behavior The effect of occupation information on expectations and search behavior
Abstract How do students respond to uncertainty in their job search? This study uses a survey experiment to understand and affect the decision-making process of investment, career choices, and labor market outcomes. Specifically, it will assess dynamic updates in students' career choices and beliefs while considering different baseline factors affecting job search behavior. How do students respond to uncertainty in their job search? This study uses a survey experiment to understand and affect the wage expectations, search behaviors, and occupation choices. Specifically, it will assess updates in students' choices and expectations while considering different baseline factors affecting these outcomes and job search behaviors.

Intervention (Public) The information treatment will provide detailed occupation-level information to students.
Intervention Start Date July 01, 2024 November 03, 2025
Primary Outcomes (End Points) Primary outcomes will center around search behavior. Search-related outcomes - Beliefs and expectations (including occupation choice beliefs at different points in time, different aspects of the choice space of the occupations, wage expectations including reservation wage) - Willingness to pay with real stakes for different information related to job search, for example, willingness to pay for continued access to the information provided by the intervention, the occupation of the mentor if provided with a mentor, other extra information about occupations, and peers - Actual search behavior and knowledge about the occupation, for example: usage of the tool to access information related to different treatment arms, attending any career-related co-curriculum activities or events, internships, course choices, grades, and the distance between course syllabus and the task content of the occupations, other investment decisions, search activities, or the use of other information sources Labor market outcomes: - Detailed job market outcomes recorded in the Graduation Employment Survey administered by the university (for example, salaries and other job-related outcomes, search-related information such as start and end dates, internships and part-time jobs, offers, courses, main challenges, and reasons for their choices).

Experimental Design (Public) By exogenously changing students’ exposure to different information, we study the effect on their search behaviors. Students will be randomized to different information treatment arms and a control arm, and they will be tracked across time.

Randomization Method Computer Otree experiment
Planned Number of Clusters 1000 students 1500 students
Planned Number of Observations 1000 students 1500 students
Sample size (or number of clusters) by treatment arms 250 in the treatment arm 1 (median information) 250 in the treatment arm 2 (spread information) 250 in the treatment arm 2 (growth information) 250 control 750 in treatment and 750 in the control arm
Power calculation: Minimum Detectable Effect Size for Main Outcomes α = 0.05, β = 0.1, δ = 0.15 SD Within-subject, F-test, H1: at least 2 of the 4 means differ Assume 25% attrition Required sample size: 848 (656 if β = 0.2) Pilot experiment (N=100-200) Main study (N=800)
Intervention (Hidden) Students will be provided with detailed occupation-level wage information based on recent years' graduation employment surveys. Students can choose from a long list of detailed occupation categories, and the treatment group will receive percentile wage information and personalized predicted average wage information based on their academic profiles. Students in the control group will receive information based on the Occupational Outlook Handbook published by the US BLS. The treatment group will also have access to this information.
Secondary Outcomes (End Points) Search behavior and search activities
