The perceived utility of information presented via electronic decision aids: A consumer perspective

Recent advancements in electronic technology have made possible a viable alternative information delivery system in the form of Electronic Decision Aids (EDAs). However, consumers will only benefit from such technological innovations if they are perceived to be useful in facilitating the decision making process. The current study investigates the effects of type of EDA format (autonomous versus dominant) and provision of educational information on the perceived utility of information presented via an electronic decision aid. In addition, the relationships between these two dimensions and specific consumer characteristics, including product familiarity, computer familiarity, and locus of control, as well as product type (search versus experience goods) are systematically identified and evaluated. Results suggest that selection of an appropriate format depends upon the nature of the product being selected, while inclusion of educational information enhances perceived utility of the information in selecting both types of products.ZusammenfassungElektronische Entscheidungshilfen in Einzelhandelsgeschäften sind eine neuartige Form der produktbezogenen Verbraucherinformation, die durch neuere technologische Entwicklungen ermöglicht wurde. Ob diese Innovation bei Konsumenten Erfolg haben wird, dürfte wesentlich davon abhängen, wie nützlich sie für den Kaufentscheidungsprozess eingeschätzt wird.Der Beitrag berichtet über eine empirische Studie darüber, wie diese wahrgenommene Nützlichkeit abhängig ist von der Informationsform (unterschieden danach, ob der sich informierende Verbraucher den Informationsvorgang eigenständig kontrollieren und gestalten kann oder nicht) und davon, ob die Information auch Bestandteile umfasst, die die generelle Produktkenntnis erhöhen und dadurch zusätzliche aufklärende Wirkung erzielen können, oder nicht. Ausserdem wurde der Einfluss der Produktart sowie der Produktvertrautheit des Konsumenten und seiner Vertrautheit mit dem Computer analysiert. Die Ergebnisse wurden in Laboruntersuchungen gewonnen, bei denen es um die Wahl eines Fotoapparates und um die Wahl eines Arztes ging.Es zeigt sich, dass es von der Produktart abhängig ist, welche der beiden Informationsformen zweckmässiger ist, wogegen durchgängig gilt, dass zusätzliche aufklärende Informationsbestandteile die wahrgenommene Nützlichkeit von Informationen erhoehen.
