The Loanable Funds Market

The Loanable Funds Market

The Real Economy

  • Focuses on the production and growth of real goods and services.

  • Specialization and trade increase economic efficiency.

  • Output measurement is essential for understanding economic performance.

Money as a Modeling Convenience

  • Money simplifies the measurement of costs, allowing us to express prices in familiar units: dollars.

  • Alternative models could use opportunity costs (e.g., peaches) for purchases, but dollars provide a standardized reference.

Money in the Real World

  • A efficient trade requires a medium of exchange (money) rather than bartering.

  • Large-scale investments necessitate organized allocation of resources (labor/capital).

The Financial Economy

  • Explores the operational aspects of financial markets:

  • Resource allocation in investments.

  • The dynamics of interest rates.

  • The rationale behind borrowing and lending practices.

  • Functionality and failures of banks and financial institutions.

  • Understanding equity markets.

Savings, Investment, and Lending

  • Savings = income not spent immediately.

  • Investment = output used to build future capital, different from everyday usage by stockbrokers.

  • Financial markets convert savings into investments for economic growth.

Borrowing & Lending

  • Banks and bond markets facilitate the flow of savings to those seeking investment.

  • Individuals borrow for substantial purchases, e.g., homes, while businesses finance profitable projects.

  • Bonds represent future repayment promises; governments issue Treasury Bonds for funding.

  • Interest Rate = return rate on loans, viewed as the price of money.

Why Save?

  • Future consumption motivates savings rather than immediate needs.

  • Individuals save for retirement and unexpected expenses; engage in various financial instruments for better returns over time.

Life-Cycle Consumption Smoothing

  • Individuals borrow when young (e.g., student loans).

  • They typically save during work years then deplete savings in retirement, preferring controlled consumption over unpredictable income fluctuations.

Supply of Savings

  • The propensity to save increases with higher return rates.

  • Example: A savings asset paying interest adjusts perceived value:

  • Interest rates affect saver behavior; higher rates incentivize saving.

Shifting Savings Supply

  • Influential factors: changes in risk perception, increased life expectancy, greater patience in financial decisions, loss of trust in financial institutions.

Interest Rates and Inflation

  • If expected inflation outpaces interest rates, savings become less appealing; consumers prefer immediate spending.

  • Real Interest Rate (adjusted for inflation) is crucial for evaluating actual savings benefit.

Inflation and Savings Supply

  • Inflation diminishes future purchasing power, impacting savings decisions, whereas deflation increases future purchasing capacity.

Borrowing

  • Borrowing enables immediate purchases with future income, facilitating ventures generating returns (e.g., rental properties).

  • Large-scale projects often require significant upfront investments; borrowing connects those with ideas to those with capital.

Example: Federal Express

  • Fred Smith based FedEx on a large-scale operational concept needing upfront investment.

  • Resulted in successful profitability leading to loan repayment and wealth accumulation for shareholders.

Example: Financing College

  • Student loans afford immediate access to education, promoting higher long-term earnings as opposed to delaying education until savings allow full payment.

Demand for Loans

  • Lower borrowing costs attract more borrowers; loan demand typically inversely proportional to interest rates.

Inflation and Demand for Loans

  • Inflation diminishes future money value, increasing demand for borrowing when rates are low.

Government Borrowing

  • Impacts overall market for loans by configuring supply and demand dynamics, often leading to increased interest rates resulting from government borrowing activities.

Government Borrowing and Interest Rates

  • Crowding out private sector investment and consumption; a significant government investment may lead to higher interest rates if public borrowing expands.

Rate Ceilings

  • Propose a discussion on credit card interest rates - what caps might do to the market and lender profitability.

Should We Ban Payday Loans?

  • Payday loans provide access to credit for those lacking other options but can result in cyclic debt traps due to high-interest rates.

How Well Do People Plan for the Future?

  • Evidence suggests poor future planning among consumers regarding borrowing needs and unexpected life events leading to potentially dangerous financial decisions.

Q&A Session

  • Open questions on the effects of capping interest rates and perceptions of borrower and lender dynamics in financial markets.
