Abstract: I am going to analyze consumers' ability to take over responsibility for their consumer behavior. To achieve this, three main questions need to be answered. First, are consumers as human beings in the right metaphysical state to take responsibility for their consumer behavior? Second, do consumers have crucial responsibility in relation to other economic participants? And third, is it possible for consumers to live up to the responsibilities that might originate from their consumption? Based on these questions, it should be possible to systematically outline all aspects of consumers’ responsibilities. The main proposal describes consumers' responsibility as a phenomenon, which arises from their constant role as citizens. Regardless of the responsibility consumers actually have, there are systematic malfunctions like the “Mind-Behavior-Gap", that disable them from living up to it. In order to correct this malfunction and to enable consumers to take over responsibility for their behavior, I am going to introduce a conceptual information system that I will call product index. This product index is supposed to gather all available product information on one website and grant users a free, widespread and independent access to this information. As a result, the user should be able to compensate the so-called "'information asymmetry"'. Addionally, the product index could be personalized in such a way that the system evaluates all products in relation to the user’s values. In my dissertation I will consider the system’s structure, its legal boundaries, its presumable social impact and the possible difficulties that may emerge with constructing and running it.
