Purpose – One core element of interactive information retrieval (IIR) experiments is the assignment of search tasks. The purpose of this paper is to provide an analytical review of current practice in developing those search tasks to test, observe or control task complexity and difficulty....

We examine the temporal stability of risk preference measures obtained by different elicitation methods in a controlled laboratory experiment at two distinct times. Our results indicate remarkable temporal stability of risk measures at the aggregated level and temporal instability at the...

This study analyzes the external validity of experimentally elicited ambiguity aversion, likelihood insensitivity and risk aversion on real-life decision-making in the field of student loans. Our main finding is that ambiguity aversion, likelihood insensitivity and risk aversion are not related...

The paper investigates risk attitudes among different types of individuals. We use several di erent measures of risk attitudes, including questions on choices between uncertain income streams suggested by Barsky et al. (1997) and a number of ad hoc measures. As in Barsky et al. (1997) and...

The external validity of experimental results is essential in the social sciences. Existing methods estimate causal effects in a target population, called the target population average treatment effect (T-PATE). However, these methods are sometimes difficult to implement either because it is...

This paper presents the findings of an artifactual field experiment conducted in urban Ecuador to investigate discrimination against LGBTQ+ (here restricted to individuals self-identified as gay or lesbian) job seekers in the labor market. Focusing on occupations and sectors where LGBTQ + and...

Consider a supply chain in which products move through multiple serial echelons before they are finally shipped to the end customer. In such a serial multi-echelon inventory system, inventory managers make dynamic decisions, called inventory replenishment decisions, to regulate inventory levels,...

The statement institutions matter has become commonplace. A precondition for it to be supported by empirical evidence, is, however, that institutions are measurable. Glaeser et al. (2004) attacks many studies claiming to prove the relevance of institutions for economic development as being based...
