Q1a. If the required reserve ratio is 10%, what are the required reserves for this bank?

Background

Topic: Money Creation and Reserve Requirements

This question tests your understanding of how banks are required to hold a certain percentage of deposits as reserves, known as the required reserve ratio.

Key Terms and Formula:

• Required Reserves: The minimum amount of reserves a bank must hold, set by the central bank.

• Required Reserve Ratio (RRR): The fraction of deposits that must be held as reserves.

Formula:

Step-by-Step Guidance

1. Identify the required reserve ratio: or .

2. Identify the total deposits: .

3. Multiply the required reserve ratio by the total deposits to find the required reserves.

Q1b. If the required reserve ratio is 10%, what (if any) are the excess reserves for this bank?

Background

Topic: Excess Reserves

This question tests your ability to calculate excess reserves, which are reserves held by a bank beyond what is required.

Key Terms and Formula:

• Excess Reserves: Reserves held by a bank above the required minimum.

Formula:

Step-by-Step Guidance

1. Find the total reserves: .

2. Calculate the required reserves (from part a): .

3. Subtract required reserves from total reserves to find excess reserves.

Q1c. Suppose this bank is the entire banking system. Given the information above, what is the maximum amount the money supply can be increased by?

Background

Topic: Money Multiplier and Money Creation

This question tests your understanding of the money multiplier and how excess reserves can lead to an increase in the money supply.

Key Terms and Formula:

• Money Multiplier: The amount by which the money supply can increase based on excess reserves and the reserve ratio.

Formula:

Step-by-Step Guidance

1. Calculate the money multiplier using the required reserve ratio ().

2. Find the excess reserves (from part b).

3. Multiply the excess reserves by the money multiplier to find the maximum possible increase in the money supply.

Q1d. If this bank is one bank operating in a multi-bank system and it makes a loan for $25,000 that is deposited in another bank, how (if any) does this loan affect the money supply?

Background

Topic: Money Creation in a Multi-Bank System

This question tests your understanding of how loans and deposits in a multi-bank system affect the money supply through the money multiplier process.

Key Terms and Formula:

• Money Multiplier: As above, .

• Excess Reserves: The amount available for lending.

Step-by-Step Guidance

1. Recognize that when a bank makes a loan, the money supply increases by the amount of the loan initially.

2. In a multi-bank system, the process continues as the loan is deposited and re-loaned, multiplying the effect.

3. Set up the calculation for the total potential increase in the money supply using the money multiplier and the initial loan amount.

Q1e. If the Federal Reserve decides to conduct open market operations and they purchase $20,000 worth of bonds from this bank, how does this purchase impact the t-account? What type of monetary policy is the Federal Reserve engaging in with this action?

Background

Topic: Open Market Operations and Monetary Policy

This question tests your understanding of how the Federal Reserve uses open market operations to influence bank reserves and the money supply, and the classification of monetary policy actions.

Key Terms and Formula:

• Open Market Operations: The buying and selling of government bonds by the Federal Reserve to influence reserves and the money supply.

• Expansionary Monetary Policy: Actions that increase the money supply, typically by purchasing bonds.

Step-by-Step Guidance

1. When the Fed buys bonds, the bank receives reserves (cash) in exchange for bonds.

2. Update the t-account: Increase reserves by $20,000 and decrease bonds by $20,000.

3. Recognize that this action increases the bank's ability to make loans, thus increasing the money supply.

4. Classify the policy: Buying bonds is an example of expansionary monetary policy.

Q2a. The economy is at potential output, however foreign economies slow dramatically. What fiscal policies would you recommend? Demonstrate both verbally and graphically how your recommended policy would impact the economy.

Background

Topic: Fiscal Policy and Aggregate Demand

This question tests your ability to recommend appropriate fiscal policy responses to changes in net exports and to illustrate the effects using the AD-AS model.

Key Terms and Concepts:

• Expansionary Fiscal Policy: Increasing government spending or cutting taxes to boost aggregate demand.

• Aggregate Demand (AD): The total demand for goods and services in the economy.

• Potential Output (Yp): The level of output when the economy is at full employment.

Step-by-Step Guidance

1. Recognize that a slowdown in foreign economies reduces U.S. exports, shifting the AD curve to the left.

2. Explain that this creates recessionary pressures (lower GDP and price level).

3. Recommend expansionary fiscal policy: increase government spending or cut taxes to shift AD back to the right.

4. Graphically, show AD shifting left (due to lower exports), then back right (due to policy response).

Q2b. The economy has been operating above the potential output causing inflationary pressures to rise. What fiscal policies would you recommend? Demonstrate both verbally and graphically how your recommended policy would impact the economy.

Background

Topic: Fiscal Policy and Inflationary Gaps

This question tests your understanding of contractionary fiscal policy and its effects on the AD-AS model.

Key Terms and Concepts:

• Contractionary Fiscal Policy: Decreasing government spending or increasing taxes to reduce aggregate demand.

• Inflationary Gap: When actual output exceeds potential output, causing upward pressure on prices.

Step-by-Step Guidance

1. Recognize that output above potential creates inflationary pressures (AD is to the right of Yp).

2. Recommend contractionary fiscal policy: decrease government spending or increase taxes to shift AD left.

3. Graphically, show AD shifting left, reducing output to potential and lowering the price level.

Q2c. A new technology is invented that significantly raises potential output. What is the effect on the economy? Demonstrate both verbally and graphically.

Background

Topic: Economic Growth and Aggregate Supply

This question tests your understanding of how technological progress affects the long-run aggregate supply (LRAS) and the overall economy.

Key Terms and Concepts:

• Long-Run Aggregate Supply (LRAS): The economy's potential output at full employment.

• Short-Run Aggregate Supply (SRAS): The relationship between the price level and output in the short run.

• Technological Progress: Increases productivity and shifts LRAS to the right.

Step-by-Step Guidance

1. Recognize that new technology increases potential output, shifting LRAS to the right.

2. Explain that SRAS may also shift right if productivity increases in the short run.

3. Graphically, show LRAS (and possibly SRAS) shifting right, increasing output and lowering the price level.
