In this article, we have applied the NTA method to France to gain an understanding of economic flows between generations. Our particular interest lies in the question how far the State and individuals share the responsibility for financing the consumption of different generations. The NTA method is based on an accounting equation whereby private and public resources and consumption are set equal. An individual's resources, income from labor and capital plus public and private transfer inflows must be equal to the use made of them, whether for consuming, saving, or making public and private transfers. Consumption and production levels are then calculated for each age, both individually and in aggregate. Transfers between ages reallocate the wealth produced during the active ages so that individuals can consume at various times in their lives. There are ages when they consume but do not produce—childhood and retirement—and other ages when they produce significantly more than they consume: adulthood.
