There has been an emerging interest in the effective luxury advertising, which has been conducted within and across national borders. Unlike earlier studies on luxury brands that focused on the behavior and opinions of luxury consumers (e.g., luxury motivations, value perceptions, etc.), this nascent stream of research queries an important role that advertising exerts on luxury consumers (Freire, 2014). Informed by these developments, our study examines how luxury brand marketers can design effective social media messages for their consumers. In particular, we draw on recent research in consumer psychology to shed new light on (1) how consumer feelings about the psychological distance of luxury consumption may influence their evaluation of different types of message appeals on social media and their intention to share these messages with others; and (2) we address how this process varies depending on (a) the perceived tie strength between consumers on social media, the functional attitudes of luxury brands, and across different cultural milieus.
