The Prosumer Index: A proposal to calculate the level of presumption

This study presents an index to calculate the level of prosumption defined as the ability of an individual to produce and consume one or more goods autonomously [1]. We analyse the concept of prosumer introduced by Toffler [2] and further developed by Kotler [3], Tapscott [4] so that the Prosumer Index (PI) can subsequently be presented. A hypothetical example is used in the work to illustrate implications and solutions to improving prosumer efficiency. This study offers a quantitative measure that can define the prosumer by calculating the level of prosumption and defining its requirements.
