Impact of the perceived risk in influencers' product recommendations on their followers' purchase attitudes and intention
研究了网红推荐产品时，粉丝感知到的风险如何影响其购买态度和意愿，发现信息真实性可缓解风险，产品涉入度也有重要作用。
The impact of the use of influencers in recommending certain products to the audience has been highlighted in recent literature on social media marketing. However, this literature has barely considered the possible perception of risk associated with these recommendations on the part of consumers or the involvement of users with the product in their purchase intention. This paper fills this gap in the literature by analysing the possible interconnection between observational learning, product involvement and perceived risk on the effectiveness of influencers' recommendations. To this end, we propose a new exploratory model applying an approach grounded in observational learning and an extension of the theory of planned behaviour, analysed by means of PLS-SEM in a sample of 948 followers of influencers who recommend fashion products. The results have new implications for influencer marketing research by reporting the impact of risk on product attitude and purchase intention, although their predictive power was lower than expected. Furthermore, perceived authenticity of the message exerted the highest positive effect on attitude, and it was established as a significant mitigator of user-perceived risk. Finally, product involvement, a construct unexplored in previous studies, revealed a considerable influence on both perceived authenticity of the message and attitude.
