Abstract
This study extends the research into the developing field of across-class associational advertising, finding that claims featuring a forthcoming model with a quality reputation for the manufacturer may be superior to non-across-class advertising for producing quality enhancements and a subsequent good value perception. However, such across-class comparisons involving an existing model without a quality advantage are likely to fail, as they may invite contrast effects. In addition, the authors experimentally vary and evaluate ad copy factors such as third-party endorsements and the number of associational prompts.
