Harrod no doubt was strongly influenced by the experience of
the nineteen thirties. His case of a high warranted rate of
growth exceeding the natural rate might be interpreted as follows
( the responsibility for this explanation feeing mine):
Our system is still adapted to the high rates of growth which
obtained in earlier stafees of capitalism in so far as its
saving propensities are high in relation to its requiremunts of
capital as determined by(_demographig and technical conditions.
A high saving propensity ,however, means a high share of profits
in the national income . Thus the implication is that the
distribution is adapted to the high rates of growth *fc±sc±HXgH
characteristic early capitalism, but ill-suited to a modern
- a mature - economy.
While Harrod assumed a very high degree of rigidity of the
saving ratio, and therefore, in my view implicitly also of the
distribution of income, the ppposite is assumed by neo-classical
theory, but also by the so-called Cambridge theory of long run
income distribution as represented by Kaldor. My own theory is
in the middle of these extremes: I assumed ^possibility of
adaptation.in principle^of the distribution to the requirements of
growth, but I realised that its practical importance in a modern
ecomomy dominated by oligopolies is limited, and therefore
there is a rigidity of distribution, though not absolute, still
sufficiently great to bring about the same result as in Harrods case:
A tendency to long run unemployment which persists even if it is
overlaid by bompensating factors like armaments and other public
expenditure financed by taxes on profits.
