The very basis of macroeconomics is the circular flow of expenditures and incomes. From this follows the conclusion that it is demand which determines supply and not vice versa. The most paradoxical result of this approach is the hypothesis that investment finances itself: by quantity adjustment, if capacity and labour are not fully employed (a typical feature of a capitalist economy) or by price adjustment, i.e. by demand-pull inflation (if capacity and labour force are underemployed).
