In this field experiment we study the selection of workers for a clerical job in Addis Ababa, Ethiopia. In particular, we analyse how jobseekers respond to a monetary application incentive and a higher wage offer, and how these interventions change the quality of the people who apply for the job.

Experimental Design
Experimental Design
We offer a monetary application incentive to a randomly-chosen third of the job seekers who call to inquire about a clerical position in Addis Ababa, Ethiopia. A second, randomly-chosen group of the same size is offered a higher wage, but no application incentive. The remaining job seekers for the control group. Job seekers in the control group are offered the baseline wage and no application incentive. We collect information about the job seekers in the initial phone call and in a follow-up phone call. Further, we collect in-detail information about the quality of the applicants: cognitive skills, non-cognitive skills, experience, economic preferences.
