An overall recognition of impulse buying under positive affect state and cognitive dissonance is explained, coupled with the conceptual framework which gave rise to the study in the last section of the book. In particular, it is highlighted that smartphone was chosen as the highly symbolic product subject to an impulse purchase, that the purchase takes place through an e-retailing channel via desktop personal computer, and that the considered target of purchasers is represented by Millennials.

The purpose of this paper is to explore the potential impact of food sharing platform business models and to identify the limits and barriers in measuring the impact. Using the “theory of change” (ToC) approach, this paper develops a theoretical framework that captures the activities, outputs and outcomes of food sharing platforms and links them to indicators.
