7. Deriving and exploring the total expenditures curve
The following graph shows total production (TP) and the level of Natural Real GDP (NRGDP) for a hypothetical economy. When Real GDP is $450
billion, consumption is $375 billion, government purchases are $30 billion, and investment is $70 billion. When Real GDP is $500 billion, consumption
is $400 billion, government purchases are $30 billion, and investment is $70 billion.
Use the blue line (circle symbol) to plot the economy's total expenditure function within a simplified Keynesian framework.

Step 2: The Effect of Saving on Total Expenditures
The following table shows data for the economy before the decrease in saving. Suppose that the decrease in saving causes consumption to rise
from $280 million to $320 million. Assume Say's law holds in this economy.
Fill in the data for the economy after the decrease in saving.

If consumption is $2.5 trillion, investment is $900 billion, government spending is $700 billion, imports are $1.2 trillion and exports are $1.4 trillion, how much is GDP? Example: If GDP rises from $6 trillion in 1994 to $8 trillion in 1999 and the GDP deflator in 1999 is 110, find real GDP in 1999 and find the percentage increase in real GDP between 1994 and 1999. First, we are asked to find real GDP in 1999. To do this we divide the nominal GDP, which is $8 trillion ($8,000 billion), by the GDP deflator for 1999, which is 110. This then is multiplied by 100. Real GDP in 1999 is $7,273 billion or $7.2 trillion. To find the percent change you must find the difference of real GDP between 1999 and 1994. Change in GDP = 7,232 – 6,000 = 1,232 You then take this difference and divide it by GDP in…arrow_forward3@ An economy has neither imports nor income taxes.

Potential outputarrow_forwardbased on macroeconomic theory, one of the following four answers is a correct description of the concept, “expenditure multiplier”. Which one? A/ It is the idea that decreasing national income affects the equilibrium level of GDP by the same amount of that decrease in income. B/ It is the concept that increasing national income affects the equilibrium level of GDP on par with the amount of increased income. C/ The expenditure multiplier is the idea that a given change in spending leads to an equal change in the equilibrium level of GDP. D/ It is the concept that an increase in spending causes a more than proportionate change in GDP.arrow_forward4.
