In survey studies, probabilistic expectations about uncertain events are typically elicited by asking respondents for their introspective beliefs. If more complex procedures are feasible, beliefs can be elicited by incentive compatible revealed preference mechanisms (“truth serums”). Various...

Since it is still unclear to what extent time allocation retrospectively reported in questionnaires, reflects people’s actual behavior, examining the accuracy of responses to time use survey questions is of crucial importance. We analyze the congruence of time use information assessed through...

In this article, the insertion of a two-staged highly interesting question in an online, survey-based field experiment is shown to produce better survey completion rate (i.e., decreases completion refusal by 8%) and sample representativeness (increases the number of moderate answer patterns by...

We consider a general sample selection model where unit and item nonresponse simultaneously affect a regression relationship of interest, and both types of nonresponse are potentially correlated. We estimate both parametric and semiparametric specifications of the model. The parametric...

During the last two decades, laboratory experiments have come into increasing prominence and constitute a popular method of research to examine behavioral outcomes and social preferences. However, it has been debated whether results from these experiments can be extrapolated to the real world...

The vibrant debate on randomized experiments within international development has been slow to accept a role for qualitative methods within research designs. Whilst there are examples of how 'field visits' or descriptive analyses of context can play a complementary, but secondary, role to...

Adaptive Design methods for social surveys utilize the information from the data as it is collected to make decisions about the sampling design. In some cases, the decision is either to continue or stop the data collection. We evaluate this decision by proposing measures to compare the collected...

Unit nonresponse or attrition in panel data sets is often a source of nonrandom measurement error. Why certain individuals attrite from longitudinal studies and how to minimize this phenomenon have been examined by researchers. However, this research has typically focused on data sets collected...

Character skills, including conscientiousness, grit or self-control are important determinants of relevant life outcomes. However, researchers struggle to find valid measures of these skills and many existing datasets lack any measures of them at all. This limits research on how these important...
