Financial models are an inescapable feature of modern financial markets. Yet it was over reliance on these models and the failure to test them properly that is now widely recognized as one of the main causes of the financial crisis of 2007-2011. Since this crisis, there has been an increase in...

A modern, decision-theoretic framework can help clarify important practical questions of experimental design. Building on our recent work, this chapter begins by summarizing our framework for understanding the goals of experimenters, and applying this to re-randomization.We then use this...

Einleitung -- Herleitung des Sinn und Zwecks der öffentlichen Rechnungslegung -- Der Sinn und Zweck der öffentlichen Rechnungslegung vor dem Hintergrund des Haushaltskreislaufes -- Der neue Sinn und Zweck der öffentlichen Rechnungslegung -- Modellvorschlag zur zweckadäquaten Abbildung von...

Die Herausforderung, das bestehende Zentrale-Orte-Konzept in Nordrhein-Westfalen zu validieren bzw. auf seine empirische Entsprechung hin zu überprüfen liegt darin, Lücken im Zielsystem des LEP plausibel zu schließen und zugleich Hinweise für ein künftiges Zielsystem zu geben. Ziel der...

Das Ziel des Beitrags besteht darin, generelle Empfehlungen zur Weiterentwicklung des ZOK aufzuzeigen. Zunächst wird auf die nach Auffassung der Verfasser gebotene raumstrukturelle Differenzierung hinsichtlich der Ausformung von Zentrale-Orte-Konzepten eingegangen. Zudem wird auf die Rolle bzw....

We examine the generalizability of internally valid estimates of causal effects in a fixed population over time when that population is subject to aggregate shocks. This temporal external validity is shown to depend upon the distribution of the aggregate shocks and the interaction between these...

To estimate causal effects from observational data, an applied researcher must impose beliefs. The instrumental variables exclusion restriction, for example, represents the belief that the instrument has no direct effect on the outcome of interest. Yet beliefs about instrument validity do not...

This paper analyzes a geographic quasi-experiment embedded in a cluster-randomized experiment in Honduras. In the experiment, average treatment effects on school enrollment and child labor were large—especially in the poorest blocks—and could be generalized to a policy-relevant population...

The identification of causal effects in linear models relies, explicitly and implicitly, on the imposition of researcher beliefs along several dimensions. Assumptions about measurement error, regressor endogeneity, and instrument validity are three key components of any such empirical exercise....

Routinedatenstudien können den Akteuren des Gesundheitswesens nützliche Informationen liefern. Infolgedessen hat die Bedeutung und wissenschaftliche Nutzung von Routinedaten der gesetzlichen Krankenversicherung in den letzten Jahren stetig an Relevanz gewonnen. Bisher liegen nur sehr...

Claims data studies are becoming an increasingly important source of information for healthcare stakeholders. The importance and scientific use of claims data of the statutory health funds has further increased. We saw a general lack of elaborated recommendations for best practices in this field...
