Explain the relationship between BOP and National income Accounts.

Solution

Economic activities generally create two types of transactions which lead to international payments and receipts. First concerns with production and sale of current output whereas the second concerns with purchase and sale of existing assets (both real and financial assets).
We have already learnt that in an open economy, final expenditure of consumers (C), Investors (I), Government (G) and Foreigners’ expenditure on our Exports (X) indicates nation's production of goods and services generating national income (Y). This can be represented in the following equation.
Y = C + I + G + X
This generated income is disposed of in the purchase of consumer goods and services (C), in making savings (S), in the payment of taxes (T) and in purchase of goods and services from abroad: (i.e., imports (M). Thus disposal of income can be shown in the following expression.
Y = C + S + T + M
Since according to national income accounting, income generated must be equal to income disposed of, therefore:
C + I + G + X = C + S + T + M
I + G + X = S + T + M
Clearly here I, G, X which partly represent generated income, are injections into income stream whereas S, T, M which partly represent disposal of income are leakages from income stream. As a result in equilibrium, planned injections must be equal to total planned leakages.
