The "Macro Identity" states that total spending in the economy (comprising 4 components) equals total income available to households (comprising 3 basic components) as follows: C + I + G + NX = C + S + T, all measured in nominal dollar terms. Recall also that NX = (X - M) and T stands for the net taxes the government collects from households. According to the U.S Commerce Department private savings are $8,000B, government budget deficit is $3,700B, investment is $4,500B, and the value of imports is 3,400B. Your firm is an exporter.
