Im et al. (2007) suggest that vicarious innovativeness, which includesAdvertising, Modeling and Word of Mouth, has a significantrelationship with new product adoption. Empirical studies supportthat these communication factors have a great impact on consumers’purchasing decision making (Bass, 1969; Rogers, 2003). Thus:H3. Advertising has a positive and direct influence on (a) reallynew product adoption, and (b) relative time of adoption.H4. Modeling has a positive and direct influence on (a) really newproduct adoption, and (b) relative time of adoption.H5. Word of Mouth has a positive and direct influence on (a) reallynew product adoption, and (b) relative time of adoption.Prior studies also suggest that consumer innate innovativenessonly influences new product adoption indirectly through domainspecific innovativeness and/or vicarious innovativeness (Im et al.,2007; Roehrich et al., 2003).H6. Domain specific innovativeness mediates the relationshipbetween consumer innate innovativeness and (a) really newproduct adoption, and (b) relative time of adoption.H7. Advertising mediates the relationship between consumerinnate innovativeness and (a) really new product adoption, and(b) relative time of adoption.H8. Modeling mediates the relationship between consumer innateinnovativeness and (a) really new product adoption, and (b) relativetime of adoption.H9. Word of Mouth mediates the relationship between consumerinnate innovativeness and (a) really new product adoption, and(b) relative time of adoption.
