Why is the aggreate demand curve downward sloping?

-The wealth effect -Interest rate effect -international trade effect -

Which of the following causes the short run aggregate supply curve to shift to the right?

-a positive technological change

What has contributed to the slow growth in employment in recent years?

-the number of baby boomers reaching retirement age -the severity of the 2007-2009 recession

short run aggregate supply curve

-upward sloping because over the short run as the price level increases, the quantity of goods and services firms are willing to supply will increase ( main reason for this is because prices of inputs rise more slowly than the prices of final goods and services )

the variables that cause the aggregate demand curve to shift :

1.changes in gvt policies 2. changes in expectations of household and firms 3. changes in foreign variables

the failure of workers and firms to predict the price level accurately results in an upward sloping SRAS curve because :

1.contract make some wages and prices "sticky" 2.firms are often slow to adjust wages 3.menu costs make some prices sticky

5 variables that shift the short run aggregate supply curve

1.increase in the labor force and in the capital stock (shift to the right) 2.technological change ( increase shifts to the right ) 3.expected changes in the future price level ( if workers and firms expect the price level to increase by a certain percentage, the SRAS curve will shift by an equivalent amount, holding all other variables constant that affect the SRAS curve ) 4.adjustments of workers and firms to errors in past expectations about the Price level

The aggregate demand curve slopes downward for all of the following reasons except:

A lower price level makes imports from other countries less expensive and US citizens bu more imports

The federal gvt. increases taxes in an attempt to reduce a budget deficit.

Because this is a change in consumption it will cause a shift to the left in the aggregate demand curve.

Firms become more optimistic and increase their spending on machinery and equipment.

Because this is a change in investments it will cause a shift to the right in the aggregate demand curve.

The us economy experiences 4 percent inflation.

Because this is a change in the price level, it will cause a movement along the aggregate demand curve.

Which statement is correct if real GDP in the US declined by more during the 2007-2009 recessions that did real GDP in Canada, China and other trading partners of the US?

Imports to the US fell more than the US exports, leading to an increase in net exports

What relationship is shown by the aggregate demand curve?

The aggregate demand curve shows the relationship between the price level and the quantity of real GDP demanded by households, firm and the gvt.

Which of the following does not cause the aggregate demand curve to shift?

a curve that shows the relationship between the price level and the quantity of real GDP demanded by households, firms and the government

long run aggregate supply curve (LRAS)

a curve that shows the relationship in the long run between the price level and the quantity of real GDP supplied. -it is a vertical line at the potential level of real GDP -shifts to the right each year ( due to increase in capital stock ) as potential real GDP increases each year

The international trade effect refers to the fact that an increase in price level will result in

a decrease in exports and an increase in imports

aggregate demand and aggregate supply model

a model that explain short run fluctuation in real GDP and the price level

an increase in the price level will cause a .... the aggregate demand curve

a movement up along

What is the effect of an increase in the price level on the short run aggregate supply curve?

a movement up along a stationary curve

If the economy adjusts trough the automatic mechanism, then a decline in aggregate demand causes

a recession in the short run and a decline in the price level in the long run

Which of the following would cause an increase in the price level ?

a reduction in taxes that increases aggregate demand

a supply shock is

a sudden increase in the price of an important natural resource resulting in a leftward shift of the SRAS curve

which of the following is usually the cause of stagflation?

a supply shock as a result of an unexpected increase in the price of a natural resource

Which of the following factors will cause the long run aggregate supply curve to shift to the right>

all of these -technological change -an increase in the number of workers in the economy -the accumulation of more machinery and equipment

The SRAS curve will shift to the left if there is

an increase in expected future prices .

if aggregate demand just increased, which of the following may have cause the increase?

an increase in gvt purchases

Which of the following scenarios would lead to a reduction in real GDP and may even cause a recession ?

an increase in oil price that causes short run aggregate supply to fall.

Which of the following scenarios would lead to an increase in the price level ?

the SRAS curve will shift to the left if there is

an increase in the expected price on an important natural resource.

the international trade effect states that

an increase in the price level will lower net exports

the SRAS curve will shift to the right if there is

an increes in productivity

supply shock

an unexpected event that causes the short run aggregate supply curve to shift

in the long run, changes in the price level do not affect eh lever of real GDP

because changes in price level do not affect the number of workers, the capital stock or technology

How can gvt policies shift the aggregate demand curve to the right?

by increasing gvt purchases

The long run aggregate supply curve is vertical because in the long run

changes in the price level do not affect potential GDP, as potential GDP depends on the size of the labor force, capital stock and technology.

stagflation is

combination of inflation and recession

workers and firms often enter into contracts that fix prices or wages for year at a time. IF the price level turns out to be higher of lower than was expected when the contract was signed, one party to the contract will lose out. Despite knowing this, workers and firms sill sign long term contracts because

contracts are common in the unionized sectors of the economy as they are seen as protection from unanticipated inflation

higher personal income taxes

decrease aggregate demand

An increase in what the price level is expected to be in the future will .... the SRAS curve because this is a change in

decrease; expectations about future prices

The price level that is currently higher than expected will ..... the SRAS curve because this is a change in

decrease; an adjustment to past errors in expectations about future prices

An unexpected increase in the price of an important raw material will .... the SRAS curve because this is a change in ....

decrease; the price of an important natural resource

The aggregate demand curve slopes downward due to the wealth effect, the interest rate effect, and the international trade effect and the demand curve for an individual product slopes downward

due to consumers substituting the more expensive product for cheaper goods.

The interest rate effect refers to the fact that a higher price level results in

higher interest rates and lower investment

household wealth

households assets - households debts

Spending on housing is likely to fluctuate more than spending by households on consumer durables such as automobiles or furniture, or spending by firms on plant and equipment because

housing is very sensitive to inters rate changes which are cyclical

International trade effect

if price level in the US increases relative to other nations, US exports will become more expense and imports will become less expensive. Foreigners may not buy as much US products, and US consumers will prefer to buy foreign goods. Exports will fall, imports will rise. Quantity of demanded will fall. Lower US prices will have the opposite effect

Which is true?

in the long run changes in the price level do not affect the level of real GDP

the short run aggregate supply curve slopes upward because of all of the following reasons except

in the short run an unexpected change in the price of an important resource can change the cost to firms

An article in the Economist magazine noted that " the economy's potential to supply goods and services is determined by such things as labor force and capital stock as well as inflation expectations" This list of the determinants of potential GDP is

incorrect since changes in the expected price level affect short run aggregate supply but no the long run aggregate supply

An article in the Economist magazine noted that " the economy's potential to supply goods and services is determined by such things as labor force and capital stock, as well as inflation expectations. This list of the determinants of potential GDP is :

incorrect since changes in the expected price level affect short run aggregate supply but no the long run aggregate supply.

increase; increase

an increase in the labor force will .... the SRAS curve because this is a change in

increase; the productive capacity of the economy

in the short run, an increase in aggregate demand ..... whereas in the long run an automatic mechanism brings ....

increases the price level and actual GDP beyond potential GDP; the economy back to potential GDP but the price level remains higher

The interest rate effect can be described as an increase the price level that raises the interest rate and chokes off

investment and consumption spending

because the slope of the aggregate demand curve we can say that a decrease in the price level

leads to a higher level of real GDP demanded

Increases in the growth rate of domestic GDP compared to the growth rate of foreign GDP will make the aggregate demand curve shift to the

left

decrease in gvt purchases shifts the aggregate demand curve to the

shift to the right

aggregate supply

shows the effect of changes in the price level on the quantity of good and services that firms are willing and able to supply -there are two types : short run and long run

suppose that workers and firms could always predict next year's price level with perfect accuracy. Under these circumstances

the SRAS curve would be the same as the LRAS

monetary policy

the actions the Federal Reserve takes to manage the money supply and interest rates to achieve macroeconomic policy objectives

Suppose a developing country receives more machinery and capital equipment as foreign entrepreneurs increase the amount of investment in the economy. As a result,

the long run aggregate supply curve will shift to the right

upward sloping; wage price stickiness and slow wage adjustments by firms

The effect of the price level on consumption is called the

wealth effect

interest rate effect.

when prices rise, households and firms need more money to finance buying and selling, so they will hold on to more money by removing money from banks or selling bonds. This drives up interest rates. They borrowing will decline. Investment spending reduces, and quantity of good san services demanded will also reduce
