Change in real GDP = change in business spending * spending multiplier
Or, spending multiplier = Change in Real GDP / Change in buisness spending
Or, Spending multiplier = $(160 - 100) billions / $15 billions = 4
Spending multiplier is the ratio of increment in income to the increment in investment. Spending multiplier depends on the marginal propensity to Consume. It shows that any person's Spending is another person's income. If investment spending increases, it increases real GDP by more than the initial increase in investment spending because of the multiplier effect. The larger the investment spending multiplier, the larger will be the stimulative effect on the economy of an investment.

What will happen to real GDP given a $30 billion increase in the money supply under...
What will happen to real GDP given a $30 billion increase in the money supply under the following assumptions? Each $5 billion increase in the money supply reduces the rate of interest by 0.50 percentage point. Each 1 percentage point decline in interest rates stimulates $100 billion worth of new investment. The spending multiplier is 2.5. Assume that the aggregate supply curve is so flat that the price level does not rise noticeably when aggregate demand increases.

The economy is in equilibrium, TP = TE, and Real GDP is $2,000 billion. The MPC is 0.75, the multiplier is operative, and idle resources exist at each expenditure round. Autonomous investment spending falls by $10 billion. As a result, the TE curve shifts __________, inventory levels unexpectedly __________, business firms __________ the quantity of goods and services they produce, and Real GDP __________ by __________. downward; rise; decrease; falls; $7.5 billion downward; fall; increase; rises; $40 billion downward; rise;...
