Market Structure and Stabilization Policy

Although such generalizations must always be made with cautions, differences in market structure - differing degrees of monopoly and competitiveness - have not usually been thought of central importance in their bearing on general price movement. It has been customary to assume broad homogeneity of product markets - the labour market is ordinarly treated as a special case - and the particular assumption have not be considered decisive for the analysis. Certainly in the Keynesian tradition market structures have been assigned a secondary role as compared with the aggregative relations of demand to the level of employment and the current capacity of the economy.
