In den Sozialwissenschaften spielt die sogenannte Citizen Science, also der Einbezug von an Wissenschaft interessierte Bürgerinnen und Bürgern in wissenschaftliche Erhebungen als Methode empirischer Sozialforschung bislang keine Rolle. Freilich sind die in der Politik zunehmend häufiger...

In this paper, we examine the determinants of self-selection into a vocational training program in India. To do this we combine data from an artefactual field experiment with survey data collected from the targeted community. We find that applicants and non-applicants differ in terms of...

In this paper, we compare participants in an artefactual field experiment in urban China with the survey population of migrants from which they were recruited. The experimental participants were more educated, more likely to lend money to friends, and worked fewer hours than the general...

Child labor statistics are critical for assessing the extent and nature of child labor activities in developing countries. In practice, widespread variation exists in how child labor is measured.

A number of development assistance programs promote community interaction as a means of building social capital. Yet, despite strong theoretical underpinnings, the role of repeat interactions in sustaining cooperation has proven difficult to identify empirically. We provide the first...

This paper reports on a randomized survey experiment among 1840 households, designed to compare pen-and-paper interviewing (PAPI) to computer-assisted personal interviewing (CAPI). We find that PAPI data contain a large number of errors, which can be avoided in CAPI. We show that error counts...

This paper tests for a number of survey effects in the elicitation of expenditure items. In particular we examine the extent to which individuals use features of the expenditure question to construct their answers. We test whether respondents interpret question wording as researchers intend and...

We replicate three pricing tasks of Gneezy, List and Wu (2006) for which they document the so-called uncertainty effect, namely, that people value a binary lottery over non-monetary outcomes less than other people value the lottery's worse outcome. While the authors implemented a verbal lottery...

Home price expectations play a central role in macroeconomics and finance. However, there is little direct evidence on how these expectations affect market choices. We provide the first experimental evidence based on a large-scale, high-stakes field experiment in the United States. We provided...
