Which of the following statements is true?
An increase in government purchases by $10 million will cause real GDP to increase by exactly $10 million.
Consumption, investment, and net export spending are all likely to change as a result of a change in government purchases.
Most conditional forecasts assume that a change in government purchases has no effect on the other spending components of real GDP.
Only consumption spending is affected by changes in government purchases.
A change in government purchases has no effect on the other spending components of real GDP.
Option (2) is correct.
When government purchases change, it leads to a more-than-proportionate change in real GDP (through multiplier effect) and income, which in turn changes consumption demand (a direct change), investment demand (a direct change) and import demand a direct change - as a result of which, Net exports (= exports - Imports) change in opposite direction of the change in real GDP.
