Führt Google Shopping zu einer neuen Art von Wettbewerbsproblem?

This paper is concerned with the question of how to deal with Google Shopping's position on online markets in order to prevent harm to public welfare. From the perspective of sellers and buyers of goods and services in Germany, Google can be seen as a gatekeeper to the Internet and thus as an essential facility. It is shown that Google Shopping represents a typical club good. Therefore, welfare-optimal rules must be adhered. In this context, it should be noted that in the current Google Shopping search results, artificial rivalry is created among the sellers to get the maximum willingness to pay for a top listing. The proposed solution in this paper provides a summary score list of all sellers of a particular product for which a quantitative independent contribution should be required instead of a fee.
