Abstract
Many individuals state that they want to work but are neither working nor actively searching for work. This may reflect “rational discouragement,” in which they correctly anticipate that their private returns to search are low. If so, encouraging these individuals to increase search effort may have private costs and potentially even negative externalities due to congestion costs. Alternatively, some individuals may fail to search despite high private returns. We conduct a field experiment in Pakistan that randomly varies the process of applying for jobs. We use this to describe the marginal individuals induced to search by an easier process and identify their private returns to search.

We are registering this trial during the COVID-19 epidemic. Our intervention end date, trial end date, and final sample size will depend on the progress of the epidemic.

Experimental Design
Experimental Design
Individual participants on Job Talash, a job search facilitation service, are randomly assigned to one of two different processes for applying for jobs. Both groups are matched regularly to posted vacancies based on their qualifications and preferences. The control group receives a text message with a short list of the matched vacancies and an invitation to call the service to submit job applications. The treatment group receives a phone call with a list of the vacancies and can submit applications during that call. We compare outcomes across individuals assigned to the different treatments to identify effects on job search and downstream employment outcomes. We use additional randomized treatments for subsamples and subperiods to evaluate mechanisms that might explain job search and employment effects.

Randomization Method
Randomization was conducted using Stata.
Randomization Unit
Treatment is assigned at the participant level. Analysis using panel data on participants (e.g. participant*vacancy application decisions) will account for within-participant clustering.
Was the treatment clustered?
No
