Call Me Maybe: Experimental Evidence on Using Mobile Phones to Survey Microenterprises

Wednesday, 30 August, 2017
Abstract: 
We run the first randomised controlled trial to compare microenterprise data from surveys of different frequency – weekly or monthly – and medium – phone or in-person. We show neither the quality of survey data nor the probability of respondents remaining in the panel differ substantially by frequency or medium, though respondents are more likely to miss higher-frequency interviews.
