Suppose that the price index of 150 for quantity
demanded of US Real GDP is 10.0 trillion worth of
goods. Do these data represent aggregate demand or
a point on an aggregate demand curve? Explain your
answer.
suppose that at a price index of 154 the quantity demand of u.s. real GDP is 10.0 trillion worth of goods. do these data represent aggregate demand or point on an aggregate demand curve? explain your answer?
"The demand curves for all products have
negative slopes. For instance, the demand
curves for milk,automobiles, personal
computers, and shirts all have negative
slopes. Therefore, because the aggregate
demand curve shows the demand for all
products, it too must have a negative slope. "

Specifically, aggregate demand shifts to the left from AD1AD1 to AD2AD2, causing the quantity of output demanded to fall at all price levels. For example, at a price level of 140, output is now $200 billion, where previously it was $300 billion. The following table lists several determinants of aggregate demand. Complete the table by indicating the change in each determinant necessary to decrease aggregate demand.

- The following graph shows an increase in aggregate supply (ASAS) in a hypothetical economy. Specifically, aggregate supply shifts to the right from AS1AS1 to AS2AS2, causing the quantity of output supplied at a price level of 125 to rise from $250 billion to $350 billion.

Economists forecast that if the government takes no action and the economy continues to grow at the current rate, aggregate demand in 2028 will be given by the curve labeled ADAADA, resulting in the outcome given by point A. If, however, the government pursues an expansionary policy, aggregate demand in 2028 will be given by the curve labeled ADBADB, resulting in the outcome given by point B. The following table presents projections for the unemployment rates that would occur at point A and point B.
