Yet as researchers increasingly conduct surveys in the developing world, little attention has been devoted to understanding how new technologies¡ªsuch as the use of electronic devices in face-to-face interviews¡ªproduce bias there. We hypothesize that using electronic devices instead of pen and paper can affect survey behavior via two pathways: a wealth effect and a surveillance effect. To test the hypotheses, we use data from a two-wave panel survey fielded in Tunisia. We investigate whether responses collected in Wave 1 with pen and paper changed when some individuals were interviewed in Wave 2 by interviewers using tablet computers. Consistent with the wealth effect hypothesis, more than half of the lowest income respondents reported a higher income in the second wave when interviewers used tablets. Conversely, we find little evidence that concerns about surveillance changed survey behavior %K Public opinion %K survey methods %K developing countries %U https://journals.sagepub.com/doi/full/10.1177/2053168019844645
