CHANGING TENDENCY OF RUSSIA DIGITAL BEHAVIOUR
Despite the availability of price comparison websites, online retailers are still able to price differentiate. The explanation of price dispersion will enable us to determine the key drivers of price premia, which are set by some of the merchants. We build a conceptual model of online pricing. In order to explain the variation of prices for the same good across different merchants, we use both merchant's characteristics (such as reputation, store format, self-delivery opportunities, SEO quality, etc.) and market characteristics (mean price, technical complexity of product category, number of sellers, the variation of sellers' ratings, etc.). Econometric estimation of this model will allow figuring out on which markets a merchant with specific characteristics will be able to set a higher price premium, which is important for merchants that need to choose the distribution channels, SEO, targeted service quality, assortment, etc.
In this study, nine methods for measuring indirect importance are compared on the basis of their discriminatory power and stability. To the best knowledge of the authors, the stability of results obtained with different methods is assessed for the first time. The deficiencies of an existing criterion for assessing diagnosticity are pointed out and a modified version suggested. The empirical comparison is based on two real-world datasets from the ecommerce industry. Even though none of the methods appeared to be the best according to both criteria simultaneously, there seem to be grounds for recommending the theoretically sound Shapley value decomposition of R-square if stability and discrimination are about equally important for a decision maker, while negative contributions are undesirable.
