Lecture 18 by Emmanuel Saez, Fall 2024
Focus on monetary policy in economic contexts.
Understanding how monetary policy influences the economy.
Short-run outputs influenced by aggregate demand.
Planned Aggregate Expenditure (PAE) depicted against output.
Factors influencing shifts in PAE:
Monetary Policy: Central bank actions impacting nominal and real interest rates.
Financial Market Disruptions: Such as financial crises affecting overall stability.
Examining various aspects of interest rates and the role of the Fed.
Presence of various nominal interest rates influenced by:
Riskiness of Bonds/Loans: Riskier investments yield higher returns.
Maturity: Length of time till the bond matures affects interest rates.
Interest rates generally move together, representing overall trends.
Bond risk rated by agencies (Moody's, S&Ps, Fitch):
AAA (safest) to C/D (junk bonds).
Evaluating attractiveness of bonds based on risk and return.
Example: Safe Federal Government bond vs riskier corporate bonds.
Long-term bonds reflect expected average short-term interest returns.
Illustration of saving mechanisms via Treasury bonds for different periods.
Interpretation of current interest rate trends and future expectations.
Money defined by three main characteristics:
Medium of Exchange: Used in transactions.

The Fed can influence short-run nominal interest rates by:
Adjusting interest on bank reserves.
Engaging in open market operations.
Monitoring the federal funds effective rate and its correlation with Treasury Bill rates.
Illustrates how money demand decreases with increasing interest rates.
Discusses the relationship between nominal interest rates set by the Fed and their impact on real rates.
Tools available to the Fed to affect nominal interest rates and their broader economic implications.
How changes in the real interest rate affect Planned Aggregate Expenditure (PAE) and economic output:
Investment Decrease: Higher rates discourage business investment.
PAE Shifts: Changes in aggregate consumption and investment based on interest rate adjustments.
Definitions of contractionary and expansionary policies and their effects on output.
Fed's actions to reduce rates during recessions and increase during economic booms.
Consequences of reduced PAE on recession and recovery patterns.
Review of Fed actions during the Great Depression and their effectiveness.
Discussion on the Zero Lower Bound.
Barriers to further rate cuts during severe economic downturns.
Definition and implications of financial crises on the economy.
Mechanisms leading to insolvency in financial institutions and examples of recent failures like Silicon Valley Bank.

Impact on lending conditions and consumer confidence, reducing aggregate demand.
Suggestions for improving stability in the banking system through deposit insurance and regulation.
