Abstract
The aim of this study, and thereby this paper, is to discover the field of input-output economics as an integral component of the wider trade theory.
We start therefore, with an introduction to the discipline, its history and its place today within the global economic context.
We move on to explain in detail the calculation of an input-output table as it is used for the total output calculations of a national as well as a regional economy. The concept of the multiplier will also be discussed here.

To conclude, we will present an example of the application of input- output economics to a specific, current issue namely, the environment.
An Introduction
The wider discipline of trade theory within which we find the field of input-output economics consists of four broader areas. Input-output economics, based on the Heckscher-Ohlin theory and defined by the findings of Wassily Leontief forms the biggest most well known part. However, there are other areas which deserve to be mentioned in order to round out the discussion. These other areas are the Ricardian model of comparative advantage, Posners technological-gap theory and Vernons product life-cycle theory.

The Ricardian model, which is the next most important model to that on which input-output economics is based, will be described in some depth for the sake of comparison and to give an alternative insight into the discipline of trade theory.

The Ricardian model then, suggests that labour costs will be the determinant of trade: the country with the lower labour cost in the production of a good will be the exporter of that commodity. This theory was tested in 1952 by MacDougall who used data on 25 products from 1937 to compare labour productivity and exports for the United States and Great Britain. In this way, MacDougall tested whether their relative exports to third countries were connected with their labour productivities. The results which MacDougall found were inconsistent with the simple Ricardian model. However, they are generally interpreted as supporting a more general “Ricardian” argument that differences in relative labour productivities are the determinant of comparative advantage. As long as these differences are due to technology, the model exists as an alternative to the model described previously.

MacDougall found that wage rates in the manufacturing sector were roughly twice as high in the United States as in Britain. Therefore, the United States should be the dominant exporter in markets where her labour productivity was more than twice as high as in Britain. Britain, on the other hand, should be the dominant supplier in any line of production where her labour productivity was more than 50% of the American. Whenever labour productivity in US industry was twice that of its British counterpart, we should expect export shares of the two countries to be roughly equal in third markets.

In most cases, the ratio of US to British exports was higher
