Abstract

By documenting that online ratings poorly correlate with quality scores provided by Consumer Reports — presumably a measure of "objective" product quality — de Langhe et al. (2016a) found that consumers rely more heavily on such ratings when making quality inferences than they should. Apart from replicating this finding, we examine the moderating effect of product age on the convergence between objective and rated quality and investigate which quality indicator is a better predictor of sales performance.
