A Comparison of CAPI and PAPI through a Randomized Field Experiment

This paper reports on a randomized survey experiment among one thousand eight hundred and forty households, designed to compare pen-and-paper interviewing (PAPI) to computer-assisted personal interviewing (CAPI). The authors find that PAPI data con...
