Abstract
In determining whether or not to mandate disclosures of product information, policymakers may wish to first investigate the relative importance of different attribute-related information cues in influencing the purchase decision-making of consumers. This paper examines the applicability of the information display approach to this research task. In addition, unresolved problems associated with the approach are addressed for the benefit of researchers interested in applying the methodology.
Zusammenfassung
Die Messung der relativen Bedeutsamkeit von Informationen über einzelne Produktmerkmale: ein Überblick über den «information display»-Ansatz. Die Planung von Maßnahmen zur Verbraucherinformation erfordert bei den Verantwortlichen Kenntnis darüber, wie sich einzelne Produktmerkmale und die entsprechenden Einzelinformationen auf die Kaufentscheidungen von Verbrauchern auswirken. Der vorliegende Beitrag konzentriert sich auf deninformation display-Ansatz als eine der Möglichkeiten, die relative Bedeutung einzelner Produktmerkmale zu erfassen. Er bietet einen Überblick über die Leistungsfähigkeit dieses Ansatzes und über Anwendungen bei verbraucherpolitischen und unternehmerischen Problemen. Dabei werden vier mögliche Indikatoren der relativen Bedeutsamkeit diskutiert.
Anschließend werden methodische Fragen bei der Verbesserung von experimentellen Untersuchungen angesprochen. Sie beziehen sich auf das zu verwendende Material und auf die Aufgaben, die die Testpersonen erfüllen sollen, auf die Spezifizierung der Produktmerkmale und darauf, welche Marken mit einbezogen werden sollen, ferner auf die Frage, ob der Markenname als ein Produktmerkmal gelten soll, und auf die Möglichkeit, die Realitätsnähe zu erhöhen, sowie schließlich auf die Frage nach der geeigneten Entscheidungseinheit für die Datenanalyse.
