Input-Output literature can be characterized as complicated and chaotic. The complications concern the nomenclature of concepts for the derived indices from the multipliers’ models, their mathematical expressions and computable applications. The terminologies’ inconsistencies often end up to a deviation between the description for these indices and their actual computation, or/and to a misunderstanding as for their usefulness and outcomes. The aim of the paper is to help the readers to face the weaknesses in the literature. In this way, the paper provide an overview with a critical look to the constructed multipliers’ matrices and their derived indicators from the I-O models, and elaborate the causes for the scrutinized confusions. The paper proposes both terminological and computational adjustments and differentiated approaches for the models and their indices, in order to ameliorate their capabilities and to exploit their peculiarities for the developmental patterns. Alternative interpretative ways and applicable expansions are suggested.

Similarities And Differences

This article outlines how different world economies define e-waste. It further looks at how the narratives coming from these definitions affect the scope of management of e-waste.  Geographical and social-economic dynamism does affect similarities and differences in approaches to the management of e-waste.   As much as each geographical location defines e-waste in its own familiar context and peculiarity, several definitions have major components left out or added, creating strengths or weaknesses for each one of them. Each definition on its own uniquely shows the regional integration in thought and how diverse it is in beliefs of what are uniquely them. This article sums up by showing how an aspect of e-waste management – disposal, has predicted how economies define e-waste and why there is need to understand different contextual definitions for different world economies so as to effectively manage electrical and electronic equipment once they reach their end of life in the context of the user. The study identifies factors that have aided disposal of e-waste, these factors include; legal and regulatory frameworks, e-waste concept, availability and affordability of the EEE. This study considers Disposal of EEE as a determinant measure of e-waste definition.
