The Exchange Rate Effect (why AD is downward sloping)

lower prices lead to a fall in the value of the currency, boosting exports.

Aggregate demand will increase.

In the long run, an increase in the price level will result in an increase in nominal wages. true or false?

true

short run

upsloping curve output prices are flexible, but input prices are fixed

According to the "real-balances effect," if prices - decline, the purchasing power of assets will decrease, so spending at each income level should rise. - increase, the purchasing power of assets will decrease, so spending at each income level should rise. - increase, the purchasing power of assets will rise, so spending at each income level should rise. - decline, the purchasing power of assets will rise, so spending at each income level should rise.

- decline, the purchasing power of assets will rise, so spending at each income level should rise.

The long-run aggregate supply curve is vertical because the economy's potential output is determined by - the availability and productivity of real resources, not by the price level. - changes in wages, and these are unchanged in the long run. - changes in prices and output that occur in the long run. - the availability and productivity of real resources, not by the output level.

- the availability and productivity of real resources, not by the price level.

The short-run aggregate supply curve is relatively flat to the left of the full-employment output because - resources are difficult to bring into production. - there are large amounts of unused capacity and idle human resources. - there are shortages of labor. - there are shortages of capital.

- there are large amounts of unused capacity and idle human resources.

Immediate short run

A horizontal line. The price level is fixed. input and output prices are fixed

The multiplier - causes an initial change in spending to generate an even larger change in the aggregate demand curve. - reduces the impact of spending changes on the aggregate demand curve. - equalizes the change in spending and the change in aggregate demand. - causes an initial change in spending to generate an equal change in saving.

causes an initial change in spending to generate an even larger change in the aggregate demand curve.

the wealth effect (why AD is downward sloping)

lower prices boost consumers' purchasing power, raising Consumption expenditures.

Which of the following will shift the aggregate demand curve to the left? - Interest rates rise. - The government raises corporate profit taxes. - There is an economic boom overseas that raises the incomes of foreign households. - The government reduces personal income taxes.

- An increase in interest rates will cause aggregate demand to shift to the left by raising borrowing costs and thereby reducing both investment spending and aggregate demand. - - An increase in corporate profit taxes causes aggregate demand to shift to the left by reducing firms' after-tax profits. This will cause firms to invest less, thereby reducing aggregate demand.

The explanation for a downsloping aggregate demand curve differs from the explanation for the downsloping demand curve for a single product because - a downsloping aggregate demand curve assumes constant money income such that a lower price causes a substitution of the now relatively cheaper product for those whose prices have not changed. - a downsloping, single-product demand curve assumes constant prices such that changes in income cause a substitution of a now relatively cheaper product for those whose prices have not changed. - a downsloping aggregate demand curve assumes constant prices such that changes in income cause a substitution of a now relatively cheaper product for those whose prices have not changed. - a downsloping, single-product demand curve assumes constant money income such that a lower price causes a substitution of the now relatively cheaper product for those whose prices have not changed.

- a downsloping, single-product demand curve assumes constant money income such that a lower price causes a substitution of the now relatively cheaper product for those whose prices have not changed.

The shape of the short-run aggregate supply curve is - upsloping, because wages adjust more slowly than the price level. - vertical, because wages adjust at the same rate as the price level. - upsloping, because wages adjust more rapidly than the price level. - horizontal, because wages adjust at the same rate as the price level.

- upsloping, because wages adjust more slowly than the price level.

Which of the following help to explain why the aggregate demand curve slopes downward? - There is an inverse relationship between consumer expectations and personal taxes. - When the price level rises, the real value of financial assets (like stocks, bonds, and savings account balances) declines. - When government spending rises, the price level falls. - When the domestic price level rises, our goods and services become more expensive to people living abroad.

- when the price level rises, the real value of financial assets (like stocks, bonds, and savings account balances) declines. - When the domestic price level rises, our goods and services become more expensive to people living abroad.

Why does the Aggregate Demand Curve slope downwards?

The Wealth Effect The Interest Rate Effect The Exchange Rate Effect: lower prices lead to a fall in the value of the currency, boosting exports.

Suppose that an economy begins in long-run equilibrium before the price level and real GDP both decline simultaneously. If those changes were caused by only one curve shifting, then those changes are best explained as the result of: - the AS curve shifting right. - the AS curve shifting left. - the AD curve shifting left. - the AD curve shifting right.

the AD curve shifting left. We know that when an AD curve shifts leftwards it causes both the price level and real GDP to decline, and another way around keeping other variables constant. However, when an AS curve shifts leftwards, it causes the price level to rise and real GDP to decline, and vice versa keeping other variables constant. Thus, the only change that can cause a decline in price and real GDP level is a leftward shift in the AD curve.
