The objectives of this manuscript are threefold; to provide a financial, and thus formal, definition of value added; measure value addition by firms across the four nodes/stages of the value chain; and third to test hypotheses as to the drivers of value creation that differ across the four nodes.First was defined value creation/
adding, and then we estimate the economic value added for 454 firms. We validate our findings by creating and employing three additional value creation measures – the modified economic value added, the creation or destruction of value, and the persistence of value creation. Finally value creation at each node of the value chain was estimated, the relative differences among firms and nodes were measured, and a model measuring the drivers of value adding were estimated.
The paper specifically proposes a framework to detect and quantify non-linear consequences in response to progressively deteriorating chain fragility factors. The paper’s approach is a novel alternative to the traditional value chain ‘risk assessment’. Application of the framework to the...
The goal of this work is to review methodologies to analyze value chains, particularly within the agribusiness sector. The first part of the analysis delves into the value chain concept, with the aim of discovering how the concept has changed from...
