Question

Evaluate an open economy from the spending approach in order to get the three sectorial balances, private, external, and public.

Answer 1

GDP for an open economy from the spending approach follows this equation:

GDP = Consumption + Investment + Government Spending + Net Exports (Exports - Imports)

It can also be written as:

GDP = C + I + G + NX (X - N)

The balance of private consumption is simply equal to C, the balance of public spending is G, and the balance of the external sector is net exports or NX.
