Econ 231 Final Exam Review
If the dollar appreciates, perhaps because of speculation or government policy, then U.S. net exports
Decrease which shifts aggregate demands left
According to the misperceptions theory of the short-run aggregate supply curve, if a firm thought that inflation was going to be 4 percent and actual inflation was 2 percent, then the firm would believe that the relative price of what it produces had
Decreased, so it would decrease production
If the dollar depreciates because of speculation or government policy, U.S.
aggregate demand shifts right. U.S. aggregate demand shifts left if other countries experiences a decrease in real GDP
A decrease in government spending initially and primarily shifts
aggregate demand to the left
When the dollar depreciates, each dollar buys
less foreign currency, and so buys fewer foreign goods.
Other things the same, a decrease in the price level motivates people to hold
less money, so they lend more, and the interest rate falls
If the government repels an investment tax credit and increases income taxes
real GDP and the price level falls
When we say that economic fluctuations are "irregular and unpredictable" , we mean that
recessions do not occur at regular intervals
Graph: Which of the following events could explain a decrease in the equilibrium interest rate from r1 to r3
A decrease in price level
Which is an example of Crowding out?
An increase in government spending increases interest rates, causing investment to fall
In the long run, which of the following depends primarily on growth rate of the money supply?
The inflation rate but not the natural rate of Unemployment
The idea that expansionary fiscal policy has a positive affect on investment is known as
The investment accelerator
The multiplier effect is exemplified by the multiplied impact on
aggregate demand of a given increase in government purchases
Suppose a shift in aggregate demand creates an economic contraction. If policymakers can respond with sufficient speed and precision, they can offset the initial shift by shifting
aggregate demand right
the process of the investment accelerator involves
positive feedback from aggregate demand to investment
If the MPC is 0.8 and there are no crowding out or accelerator effects, then an initial increase in aggregate demand of $120 Billion will eventually shift the aggregate demand curve to the right by
$600 Billion
Take the following information as given: * when income is $10,000, consumption spending is $6,500 * when income is $11,000, consumption spending is $7,250 The marginal propensity to consume for this economy is
0.750
Graph: There is an excess demand for money at an interest rate of
2 %
Suppose policymakers take actions that cause a contraction of aggregate demand. Which of the following is a short-run consequence of this contraction?
All are correct; The inflation rate decreases, the level of output decreases, the unemployment rate increases
Graph: Faced with the shift of the Phillips curve from PC1 to PC2, policymakers will
All the above;
Which of the following effects helps to explain the slope of the aggregate-demand curve
All the above; the exchange rate effect, the wealth effect, the interest rate effect
In 2009 Congress passed legislation providing states with funds to build roads and bridges. It also instituted tax cuts. Which of these shifts aggregate demand rights?
Both the increased funding for states and the tax cuts
Changes in the price level affect which components of aggregate demand?
Consumption, investment, and net exports
what actions could be taken to stabilize output in response to a large decrease in U.S. net exports
Decrease taxes or increase the money supply
In recent years, the federal Reserve has conducted policy by setting a target for the
Federal Funds rate
In inflation is less that expected , then the unemployment rate is
Greater than the natural rate. In the long run the short run Phillips curve will shift left.
If unemployment is above its natural rate, what happens to move the economy to Long run equilibrium
Inflation expectations fall which shifts the short run Phillips curve to the left
Which of the following is correct according to the long run Phillips cure?
Monetary policy cannot change the natural rate of unemployment, but other government policies can
Liquidity preference theory is the most relevant to the
Short run and supposes that the interest rate adjusts to bring money supply and money demand into balance
The government builds a new water-treatment plant. The owner of the company that builds the plant pays for her workers. The workers increase their spending. Firms from which the workers buy goods increase their output. This type of effect on spending illustrates
The multiplier effect
A policy that raised the natural rate of unemployment would shift
both the short run and the long run Phillips curves to the right
Other things the same, continued increases in the money supply lead to
continued increases in the price level but not continued increases in real GDP
Other things the same, if workers and firms expected prices to rise by 2% but instead rise by 3 %, then
employment and production rise
The long-run aggregate supply curve would shift left if the amount of labor available
decreased or Congress made a substantial increase in the minimum wage
the opportunity cost of holding money
decreases when the interest rate decreases, so people desire to hold more of it.
If policymakers accommodate an adverse supply shock, then in the short run the unemployment rate
falls and the inflation rate rises
When the price level falls
households want to lend more, so the interest rate falls, making the quantity of goods and services demanded rise
Macroeconomic forecasts are
imprecise; this makes policy lags more relevant
Most economists believe that classical macroeconomic theory is a good description of the economy
in the long run, but not in the short run
The Fed is concerned about stock market booms because booms
increase both consumption and investment spending
Which of the following shifts aggregate demand to the right?
increases in the profitability of capital due perhaps to technological process.
Aggregate demand shifts right when the Federal Reserve
increases the money supply
The position of the long run aggregate supply curve
is determined by resource usage and technology
According to the theory of liquidity preference, money demanded
is negatively related to the interest rate, while the money supply is independent of the interest rate
Graph: If the economy starts at A and moves to D in the short run, the economy
moves to C in the longrun
When the dollar depreciates, U.S.
next exports rise, which increases the aggregate quantity of goods and services demanded.
Which of the following can explain the upward slope of the short-run aggregate supply curve
nominal wages are slow to adjust to changing economic conditions
A decrease in the expected price level shifts
only the short-run aggregate supply curve right.
Monetary policy and fiscal policy influence
output in the short run only
Graph: Suppose the economy is currently at Point A. To restore Full employment, the federal reserve should
sell government bonds, which will reduce the money supply
In the long run, a decrease in the money supply growth rate
shifts the short run Phillips curve left so unemployment returns to its natural rate
Other things the same, as the price level falls,
the dollar depreciates
Liquidity preference refers directly to Keynes' theory concering
the effects of changes in money demand and supply on interest rates
The economy will move to a point on the short run Phillips curve where unemployment is higher if
the inflation rate decreases
To say that the natural rate of unemployment changes over time is to say that
the long run Phillips Curve shifts over time
In which of the following cases does the aggregate demand curve shift to the right?
the money supply increases, causing the interest rate to fall
The position of the long run Phillips curve and the long run aggregate supply cure both depend on
the natural rate of unemployment, but not monetary growth
The lag problem associated with fiscal policy is due mostly to
the political system of checks and balances that slows down the process of implementing fiscal policy
Keynes argued that aggregate demand is
unstable, because waves of pessimism and optimism create fluctuations in aggregate demand
If output is above its natural rate, then according to sticky-wage theory
workers and firms will strike bargains for higher wages. This increase in wages shifts the short run aggregate supply curve left
