The Impact of Missing Values on PLS, ML and FIML Model Fit
(2020)
Structural equation modelling has become widespread in the marketing research domain due to the possibility of creating and investigating latent constructs. Today, several estimation methods are available, each with strengths and drawbacks. This study investigates how the established estimation methods of partial-least-squares (PLS), maximum likelihood (ML) and full-information maximum likelihood (FIML) perform with an increasing percentage of missing values (MVs). The research was conducted by investigating an adapted ...

Rechtsverträgliche und qualitätszentrierte Gestaltung für "KI made in Germany"
(2020-02-21)
Künstlich intelligente (KI) Systeme erfreuen sich immer größerer Beliebtheit. Insbesondere smarte persönliche Assistenten (SPAs) von Amazon, Google und vielen weiteren verzeichnen ein stetiges Marktwachstum. Den vielfältigen Potenzialen dieser KI-Systeme stehen jedoch auch zahlreiche Risiken gegenüber. Berichte von Datenpannen und -lecks häufen sich und haben bei Nutzern eine zunehmende Skepsis zur Folge, was zu einem gespaltenen Bild von KI in der Gesellschaft beiträgt. Diesem Problem stellt sich das Forschungsprojekt ...

A comparison of individual and group behavior in a competition with cheating opportunities
(2020)
While it is well established that individuals and groups make different economic decisions, the reasons for the behavioral differences are still not fully understood. We experimentally compare individual and group behavior in a competitive setting where cheating can be used to outperform the competitor. Our design allows us to exogenously control for the type of the decision maker, the type of the competitor, and whether the competitor is able to cheat or not. The results show that there is much more cheating in ...

A review of inter-firm relationship quality in supply chains
(2020-03-28)
Purpose – This paper aims to conduct a review of the recent literature on inter-firm relationship quality (RQ) in supply chain (SC) settings.
Design/methodology/approach – 100 English-language scientific publications on inter-firm RQ, published from 2006 to 2015 were selected and analyzed by using a content analysis approach.
Findings – The results of the frequency analysis map the antecedents, dimensions and consequences - particularly the performance and behavioral intentions of collaborating partners - of ...

Responsibility and prosocial behavior - Experimental evidence on charitable donations by individuals and group representatives
(2020-11-13)
In this paper we present a lab-in-the-field experiment with a large and diverse sample to compare charitable donations when individuals decide for themselves only and when they decide as a group representative. In contrast to the previous literature, we find that individuals make greater charitable contributions when they decide as a group representative than when they decide alone. This result demonstrates that being responsible for a group does not always lead to more selfish behavior.

A systematic literature review exploring uncertainty management and sustainability outcomes in circular supply chains
(2021)
The circular economy (CE) has inspired the emergence of circular supply chains (CSCs) to reduce the environmental impacts of linear production systems. However, the transition to CSCs faces numerous challenges and uncertainties, which in turn impact the sustainability performance of CSCs. Following a systematic review process, this paper aims to identify the uncertainties that CSCs entail and the uncertainty management strategies which can be used to mitigate them to enhance their sustainability performance. A ...

Consumers ’ perception of sustainable packaging in the food industry: An online experiment
(2022-01)
Consumers evaluate products and make purchasing decisions based on packaging and its sustainable aspects. This research investigated how different packages and their quality, eco-friendliness, expensiveness, and convenience affected consumers’ intentions to purchase. Our sample comprised 299 French consumers of muesli cereals. We conducted an online choice experiment to analyze and measure consumers’ perception of sustainable packaging, comparing three distinct experimental groups. Findings revealed that quality and ...
