Primary Outcomes (End Points) Whether people are willing to call back or send emails to contact us for each resume. Whether and how soon people are willing to call to contact us: 1. Total calls: the number of the first call received for each resume in each treatment. 2. Distribution of calls received over time. 3. Hazard rate: time duration between the time a resume is delivered and the first call received. 4. Whether a helper contacts and communicates with us more than once (through phone call or text message) for one resume.
Experimental Design (Public) We put the resumes in file bags and select public locations where shared bikes are parked to drop. Shared bikes, equipped with a basket, are one of popular ways of transportation and are widely distributed in urban areas of China. Therefore, any pedestrians passing through could find it accidentally and potentially become our helpers. Each call or email from unpaid passersby will be replied at any time and be recorded accurately. We put the resumes in file bags and select public locations where shared bikes are parked to drop.

Secondary Outcomes (End Points) Whether helpers proactively mentioned or proposed more altruistic ways of helping relative to processing resumes on the spot: delivering back to the location appointed by experimenters, handing over to a third party or requiring self pick-up at locations convenient for helpers; Whether helpers contact and communicate with us more than once. Helpers’ characteristics and other aspects that impact whether and whom they want to help: helper’s gender and location, where the resume is located, time of the day.
