Leontief  Input-Output Pollution System:

An Alternative Formulation and Generalizations

Abstract. An alternative formulation of the Leontief's input-output
pollution model is provided. It describes the flow of pollution through all
sectors of the economy, and allows each sector to evaluate pollution
generated by different manufacturing processes simultaneously. While the
Leontief's model requires both the technology matrix of the economy and a
rectangular matrix of pollution output coefficients, the new model requires
only an equivalent pollution "technology" matrix of the economy. The new
model enables each sector of the economy to select and produce a product
that emits the least amount of pollutants. For a given amount of pollutants
emitted by a sector, a method for computing the corresponding number of
items to be manufactured by that sector is provided. Examples are given to
demonstrate an application of the model.

In this project, we use simple mathematic tools to solve an important
economic and environmental problem. This talk should be of interest to those
in economics, environmental sciences, and any body who has any concern about
pollution levels in our cities.
