People buy counterfeit luxury goods for a range of reasons, including status and belonging. Previous research has shown these stem from an individual's value-expressive or social-adjustive attitudes. However, there appears to be limited research identifying a clear causal relationship between these and intention to purchase counterfeit goods, or how these attitude functions might be used to inhibit purchase of counterfeit luxury products. Using a mixed (survey/experiment) design, in two studies this research demonstrates an individual's social adjustive function has a positive influence on purchase intent for counterfeit luxury goods. However, the use of value expressive ad appeals can limit this effect on consumer decision making. The findings also demonstrate the existence of contingent effects across different levels of product involvement and product knowledge. The contingent effects help better understand the inconsistent findings in the literature regarding the influence of value-expressive and social-adjustive functions on counterfeit purchase intention, and shed light on the interplay among these variables.
