Explain relationship between BOP and National Income Accounts.

Income generated by production and sale of current output is shown as:
Y = C + I + G + X
Income disposed of in the purchase of consumer goods, savings, taxes and imports is shown as:
Y = C + S + T+ M
Since income generated must be equal to income disposed of, therefore,
C + I + G + X = C + S + T + M I + G + X = S + T + M
Here I, G, X are injections and S, T, M are leakages from circular flow of income.
In equilibrium planned injections must be equal to total planned leakages.
