Out-of-Stock (OOS) is a prevalent problem customers face at the POS. In this paper, we demonstrate both theoretically and empirically how OOS-induced substitution patterns can be explained and predicted by means of context and phantom theory. We further analyze the relevance of promotions, for...

In general, consumer preferences depend on the context of a decision situation. This paper highlights the context-dependence of substitution behavior in out-of-stock (OOS) situations and provides evidence for the relevance of promotion as essential driver of customers' OOS reactions. We...

Several approaches for subset recovery and improved forecasting accuracy have been proposed and studied. One way is to apply a regularization strategy and solve the model selection task as a continuous optimization problem. One of the most popular approaches in this research field is given by...

Kooperation ist ein unverzichtbarer Leistungsbestandteil. Nur durch kooperatives Verhalten gelingt die Abstimmung der Arbeitstätigkeiten, ohne Kooperation gibt es keinen Informationsaustausch, keine Unterstützung und keine Hilfe, sondern allenfalls eine Menge unfruchtbarer Konflikte....

Aufbauend auf einer Befragung von F&E-Mitarbeitern wird eine empirische Analyse des Zusammenhangs zwischen Zufriedenheitsfacetten und Arbeitsplatzmerkmalen, dem organisationalen Commitment und der Fluktuationsneigung durchgeführt. Zur Erstellung des Analyserahmens wird auf Erkenntnisse der...

Der Artikel gibt einen Überblick zum Stand der Forschung zur Qualitätssicherung in der ambulanten Pflege. Es werden Erfahrungen und Instrumente zur Messung von Patientenzufriedenheit referiert. Die unzureichende theoretische Fundierung der meisten Meßinstrumente wird als Manko herausgestellt....

In this paper we study the sources of wage growth. We identify the contribution to such growth of general, sector specific and firm specific human capital. Our results are interpretable within the context of a model where the returns to human capital may be heterogeneous and where firms may...

Motivated by economic-theory concepts - the Fisher hypothesis and the theory of the term structure - we consider a small set of simple bivariate closed-loop time-series models for the prediction of price inflation and of long- and short-term interest rates. The set includes vector...

Feenstra and Ma (2008) develop a monopolistic competition model where firms choose their optimal product scope by balancing the profits from a new variety against the costs of cannibalizing sales of existing varieties. While more productive firms always have a higher market share, there is no...
