We evaluate the effects of an online self-assessment tool on teachers' competencies and beliefs about ICT in education. The causal impact of the tool is evaluated through a randomized encouragement design, involving 7,391 lower secondary teachers across 11 European countries. Short-run impact...

We challenge the standard definition of economic rationality as consistency by making use of a novel distinction between axioms of decision theory: consistency and preference axioms. We argue that this distinction has been overlooked by the literature and, as a result, evidence that consistency...

The subject of this work is random coefficient regression models with only one observation per observational unit (individual). An analytical solution in form of optimality conditions is proposed for optimal designs for the prediction of individual random effect for a group of selected...

When choosing a partial factorial design for best-worst scaling (BWS) or other discrete choice experiment, researchers are faced with design size choices. This work investigates differences between two case 1 (object) BWS choice experiment designs that varied in choice set size and number of...
