Monetary Policy Study Notes

Chapter 15: Monetary Policy

Federal Reserve

  • Creation: Established in 1913 as a "lender of last resort" to provide low-interest loans to banks during financial panics.

  • Broader Responsibility: Expanded during the Great Depression to promote three primary goals:

    • Maximum employment

    • Stable prices

    • Moderate long-term interest rates

Monetary Policy

  • Definition: The actions taken by the Federal Reserve to manage the money supply and interest rates to achieve its economic objectives.

Goals of Monetary Policy

  1. Price Stability

    • Rising prices diminish the value of money as a medium of exchange and a store of value.

    • Historical Focus: Chairmen Paul Volcker (1979-1987), Alan Greenspan (1987-2006), and Ben Bernanke (2006-present) emphasized inflation control.

    • Long-term perspective: Low inflation allows greater flexibility for the Fed to mitigate recession impacts.

  2. High Employment

    • Unemployment leads to financial distress and lowers self-esteem among non-working individuals.

    • The aim for high employment extends to all governmental branches.

  3. Economic Growth

    • Stable economic growth allows households and firms to plan effectively, fostering long-term investments necessary to sustain growth.

  4. Stability of Financial Markets and Institutions

    • The Fed ensures financial market stability to facilitate an efficient flow of funds from savers to borrowers.

    • Inefficiencies in this process can result in lost resources.

The Money Market and Monetary Policy Targets

  • Unemployment and Inflation: The Fed aims to keep both rates low but cannot directly influence them. Instead, it manipulates factors known as monetary policy targets.

  • Monetary Policy Targets:

    1. Money Supply

    2. Interest Rates

  • These targets are interrelated and can indirectly influence variables of importance such as real GDP, employment, and price levels.

Money Demand

  • Demand for Money:

    • When interest rates decrease, the quantity of money demanded typically increases due to the lower opportunity cost of holding liquid cash instead of financial assets.

  • Money Demand Curve:

    • Downward-sloping reflecting that as interest rates fall, the quantity of money demanded increases.

Shifters of the Money Demand Curve

  1. Changes in Real GDP

    • Higher GDP implies increased income, resulting in greater money demand for transactions.

    • Conversely, a decline in GDP decreases money demand.

  2. Changes in Price Level

    • An increase in price levels raises the quantity of money required for transactions, while a decrease diminishes this need.

Shifts in the Money Demand Curve

  • A decrease in real GDP or the price level shifts the money demand curve leftward.

  • An increase in real GDP or the price level shifts the money demand curve rightward.

Money Supply Curve

  • The Federal Reserve exerts complete control over the money supply, depicted by a vertical supply curve.

Changes in Money Supply

  • To Increase Money Supply:

    • Purchase treasuries in open-market operations.

    • Lower the discount rate.

    • Decrease the required reserve ratio.

  • To Decrease Money Supply:

    • Sell treasuries in open-market operations.

    • Raise the discount rate.

    • Increase the required reserve ratio.

Equilibrium in the Money Market

  • Determining Interest Rates: The equilibrium interest rate adjusts to balance money supply and demand, ensuring that the quantity of money demanded matches the quantity of money supplied.

  • Effects of Rates on Money Holdings:

    • If the interest rate exceeds equilibrium, quantity demanded is less than supplied—leading people to shift to interest-earning assets, driving rates lower.

    • If the interest rate falls below equilibrium, quantity demanded exceeds supply, prompting people to sell other assets to meet their monetary needs, thus raising rates.

Interest Rate Models

  • Two models of interest rates:

    1. Loanable Funds Model: Focused on long-term real interest rates.

    2. Money Market Model: Focused on short-term nominal rates.

The Federal Funds Rate

  • Importance: A critical interest rate for monetary policy, defined as the rate banks charge each other for overnight loans.

  • Historical trends depict fluctuations in actual federal funds against target rates from 1997 to 2007.

Monetary Policy Impact on Economic Activity

  • Changes in interest rates primarily affect consumption, investment, and net exports, but not government purchases.

Effects by Component:

  1. Consumption:

    • Lower interest rates drive consumption up and savings down.

  2. Investment:

    • Decreasing rates leads to increased firm investments and makes stocks more appealing.

  3. Net Exports:

    • Rising U.S. interest rates compared to foreign rates attract foreign investment, increasing the dollar's value, which eventually reduces net exports.

Types of Monetary Policies

  1. Expansionary Monetary Policy:

    • Employed when potential GDP exceeds actual GDP, such as during recessions.

    • Goals include boosting output, profits, and consequently employment, although inflation may rise.

  2. Contractionary Monetary Policy:

    • Utilized when actual GDP surpasses potential GDP, such as periods of high inflation.

    • Aims to reduce spending, thereby increasing unemployment and lowering output and income.

Summary of Monetary Policy Mechanisms

  • Expansionary Policy:

    • Results in decreased interest rates, boosting investment and consumption, shifting AD curve right, leading to increased GDP and price levels.

  • Contractionary Policy:

    • Results in increased interest rates, which suppresses spending, shifting AD curve left, and causing decrease in GDP and price levels.

Challenges and Limitations of Monetary Policy

  • The Fed's ability to act swiftly can mitigate recession effects but cannot eliminate them entirely due to reactive delays.

  • Timing is critical; delayed responses can destabilize the economy.

Stock Market Reactions to Monetary Policy

  • Changes in the Federal Funds Rate directly influence the stock market:

    • Lower rates can lead to higher GDP and firm profits, increasing stock prices.

    • Conversely, higher rates render stocks less attractive, resulting in price declines.

Alternative Perspectives on Monetary Policy

  • Some economists suggest the Fed should prioritize money supply targeting over interest rates, a stance associated with monetarism, notably advocated by Milton Friedman.

  • Taylor Rule: A formula connecting the Fed's target for the federal funds rate to economic indicators:

    • Federal funds target rate = Current inflation rate + Real equilibrium federal funds rate + (1/2) x Inflation gap + (1/2) x Output gap.

Key Concepts Defined

  • Inflation Gap: Difference between the current inflation rate and the target rate.

  • Output Gap: Percentage difference between real GDP and potential GDP.

Considerations of Federal Reserve Independence

  • Proponents of Fed independence argue that greater autonomy leads to lower inflation rates.

  • Critics note that since monetary policy derives from unelected officials, there is diminished accountability to voters compared to elected representatives.
