Unit 3 Review

Imagine John and Batman receive a bonus of $1000 each. If Batman decides to spend $800 of his bonus, what does the $800 represent for Batman?

• The percentage of the bonus that is invested

• The percentage of the bonus that is spent

• The percentage of the bonus that is saved

• The percentage of the bonus that is taxed

Answer explanation

The marginal propensity to consume is the percentage of new income that is spent, not saved, invested, or taxed.

Imagine a government decides to increase spending on infrastructure by $1 billion. Chase and Atkins are discussing what the spending multiplier formula calculates in this scenario. What is it?

• The change in consumer spending habits

• The total savings in an economy

• The impact of this new spending on GDP

• The total amount of taxes collected

Answer explanation

The spending multiplier formula calculates the impact of new spending on GDP, showing how much the initial spending increases total economic output.

Imagine a government decides to increase spending in the economy. Henry and Cook are discussing the formula to calculate the total impact of this spending on the economy's output. What formula would they use?

• 1 divided by 1 plus the marginal propensity to save

• 1 divided by 1 minus the marginal propensity to consume

• 1 divided by the marginal propensity to save

• 1 divided by the marginal propensity to consume

Answer explanation

The correct formula for the spending multiplier is 1 divided by 1 minus the marginal propensity to consume, as it takes into account the portion of income that is not spent.

Imagine an economy experiencing a decrease in aggregate demand. Mrs. Shaw, an economist, suggests exploring the reasons behind this downward trend. What could be these reasons?

• The inflation effect, interest rate effect, and wealth effect

• The net export effect, inflation effect, and interest rate effect

• The wealth effect, productivity effect, and net export effect

• The wealth effect, interest rate effect, and net export effect

Answer explanation

The downward sloping aggregate demand curve is caused by the wealth effect, interest rate effect, and net export effect.

Imagine a country is experiencing a recession. Which of the following are likely to shift its aggregate demand curve to the right, potentially leading to economic recovery?

Consider this scenario as discussed by Phoenix and Waylon in their economics project.

• Consumer spending, gross investment, government purchases, and net exports

• Taxes, subsidies, government purchases, and exports

• Consumer savings, gross investment, taxes, and imports

• Wages, productivity, inflation expectations, and net exports

Answer explanation

The correct answer is consumer spending, gross investment, government purchases, and net exports as they are the aggregate demand shifters.

Imagine a local bakery where Henry and Atkins are discussing. What does the short-run aggregate supply curve show in the context of this bakery?

• The relationship between the price of bread and the quantity of bread produced in the long run

• The relationship between the bakery's expectations of future bread prices and the quantity of bread produced

• The direct relationship between the price of bread and the quantity of bread produced in the short run

• The inverse relationship between the wages of bakery workers and the quantity of bread produced

Answer explanation

The short-run aggregate supply curve shows the direct relationship between price level and quantity of goods produced in the short run.

Imagine a country's economy is growing due to an increase in the efficiency of its factories, largely thanks to the innovative methods introduced by Henry and Phoenix. What does this scenario most likely cause in the short-run aggregate supply curve?

• An increase in resource prices

• Higher inflation expectations

• A decrease in productivity

• An increase in productivity

Answer explanation

An increase in productivity shifts the short-run aggregate supply curve to the right by allowing more goods and services to be produced at every price level.

Imagine a country's economy is growing steadily without any short-term fluctuations. What determines the position of this country's long-run aggregate supply curve, as discussed in Mr. Dubose's economics class?

• The current level of technology

• Short-term economic fluctuations

• The full employment quantity of output

• The current price level

Answer explanation

The long-run aggregate supply curve's position is determined by the full employment quantity of output, not by short-term fluctuations, technology, or the current price level.

Imagine a country where the demand for goods and services is higher than what the economy can produce at full employment. Mr. Cook wonders, what does this scenario describe?

• When current output is less than the long-run potential output

• When current output exceeds the long-run potential output

• When the economy is at long-run equilibrium

• When inflation rates exceed expected levels

Answer explanation

An inflationary gap occurs when current output exceeds the long-run potential output, leading to increased demand and rising prices.

Imagine a scenario where the economy enters a recession. What role do automatic stabilizers play in this situation, according to Coach's analysis?

• They control the supply of money in the economy

• They stabilize interest rates to prevent inflation

• They decrease the budget deficit during expansions and increase it during contractions

• They increase the budget deficit during expansions and decrease it during contractions

Answer explanation

Automatic stabilizers decrease the budget deficit during expansions by reducing government spending and increasing tax revenue, and increase it during contractions by boosting spending and cutting taxes.
