【摘要】There have been enduring calls for online retailers to equip shopping websites with product recommendation agent (RA), i.e., 

a shopping aided feature that offers product suggestions to consumers, and product review information, i.e., product review based 

on expert evaluations or/and customers' consumption experience. Building on the preference inconsistency paradox, which depicts 

paradoxical focuses of consumers at two different shopping decisional stages, this research proposes a principle governing the 

provision of product recommendations based on product review information. An experiment simulating online shopping was 

conducted to assess the proposition, i.e., the influence of two recommendation junctures (i.e., at the beginning of product search 

and after a choice is made but before confirmation) and two recommendation justifications (i.e., product reviews from consumers 

or experts) on online consumer decision-making performance. A further study was conducted to understand the cultural differences 

in the impact of recommendation junctures and justifications.
