Impact of Consumption Models’ Change on Sustainable Development

The consumption economic theory, which was propounded by Ernest Engel (1821-1896), has been substantially improved over time, by the contributions of the modern economists. However, the extensive themes of the studies about the euro-atlantics populations’ consumption models (as well as populations from other geographical areas) still remain a domain relatively less explored and known. At present, no appreciable understanding of the consumers’ behavior exists and especially of the real motivation for adopting certain consumption practices. Although in this domain a lot of studies, observations and investigations had been conducted. In this paper, the authors analyzed the change impact of the consumption models in the context of a sustainable development. The analysis follows the evolution of the phenomena, as well as it concerns the general characteristics at the global level.
