While there may be several such industries to which the model of this paper is applicable, the authors make particular claim of relevance to the explanation of the course of wages and prices in the steel industry of the United States since World War 2.
The model of this paper considers an industry which is not characterized by vigorous price competition, but which is so basic that its wage-price policies are held in check by continuous critical public scrutiny.
For expository purposes, this is best treated as a model which spells out the conditions under which an important industry affected with the public interest would find it profitable to raise wages even in the absence of union pressures for higher wages.
The industry with which this model is concerned is a basic industry, producing a substantial share of gross national product.
The industry of this model is so important that its wage and price policies are affected with a public interest.
In this model, then, the industry is presumed to realize that they could successfully resist a change in the basic wage rate, but since such a change is the only effective means to raising prices they may, in circumstances to be spelled out in Part 2, below, find it to their advantage to allow the wage rise.
From this presumption it is an easy step to the conclusion that any observed increases in the basic wage rate must be due to union behavior different and more aggressive than assumed in our model.
