This is true by definition: Thus, output Y can be broken into two components: We can use tire right-hand side of 1 and 2 to get: The simplest way to understand this identity is to think of firms as producing a certain amount of goods, the value of which is just equal to the income received by all individuals in the economy here the entire sales revenue of firms is paid out as income to factor-suppliers.
That portion of national income which is not spend on consumption goods is saved. On the output side, firms either sell the goods they produce or put them into inventory, for future sale.

Unfortunately, nearly all of these assumptions are flawed. Empirical evidence reveals that: What is the ultimate source of the internally generated funds? It would be the expenditures of consumers and firms and government, not savings.
These statistics tell us that only a fraction of total savings is directed, ultimately, to the noble purpose of improving economic efficiency. Much of the money that is saved is ultimately spent on consumption e.
