　　This paper tests validity of widely applied Rauch (1999) classification schemes (conservative and liberal) to identify product quality differentiation and quality homogeneity.Using the most disaggregated country-product level unit value data (1995-2013), this paper provides the supportive evidence that both schemes are equally well suited for capturing product quality differentiation, while conservative scheme performs better than liberal scheme to capture the product quality homogeneity.In order to extensively sort out the quality differentiated (homogeneous) products, we suggest the future research to use Rauch conservative scheme.Besides, Rauchs classification of homogeneous products with reference price performs less efficiently to identify quality homogeneity than the classification of homogeneous goods traded on organized exchange.
