Cognitive ability measures are often taken as explanatory variables in regression analysis, e.g., as a factor affecting a market outcome such as an individual's wage, or a decision such as an individual's education acquisition. Cognitive ability is a latent construct; its true value is...

We employ a psychometrically validated performance test to study economic competence among a large and representative sample of early secondary school students in Southwest Germany. The rich dataset allows us to study variation in economic competence across school types and observable student...

We study the impact of child work on cognitive development in four Low- and Middle-Income Countries. We advance the literature by using cognitive test scores collected regardless of school attendance. We also address a key gap in the literature by controlling for children's complete time...

Agricultural sustainability (AS) is a key component in the UN's Sustainable Development Goals. Despite wide use of the concept in both research and policy, there is still not a universally accepted method for its measurement. This research proposes using item response theory (IRT) to generate a...

We introduce a test of economic competence for German-speaking secondary school students and provide evidence from a large-scale assessment with 6,230 students from grades seven to ten. The article presents the development and psychometric properties of the scale, as well as an investigation of...

Measurement invariance is a fundamental assumption in item response theory models, where the relationship between a latent construct (ability) and observed item responses is of interest. Violation of this assumption would render the scale misinterpreted or cause systematic bias against certain...

Differential item functioning (DIF) can lead to an unfair advantage or disadvantage for certain subgroups in educational and psychological testing. Therefore, a variety of statistical methods has been suggested for detecting DIF in the Rasch model. Most of these methods are designed for the...

We study the relationship between child work and cognitive development in four Low and Middle Income Countries. We address a key weakness in the literature by including children's full time-use vector in the analysis, which leads to different findings from previous studies which do not...

In diesem Beitrag stelle ich Ergebnisse aus einer explorativen Studie vor, in der das Finanzwissen von Studierenden und die Rolle zentraler Agenten der finanziellen Sozialisation untersucht wurden. In der Studie wurde eine adaptierte Version einer Skala des objektiven Finanzwissens verwendet. In...
