Study Notes

Saving

Saving is defined as current income minus expenditures on immediate needs.
Example: If Elaine earns 4,000monthlyandspends4,000 monthly and spends 4,000monthlyandspends3,600, her saving is $400 (10% saving rate).
Factors influencing saving include:
- Life-cycle saving: For future needs like retirement and education.
- Precautionary saving: For emergencies, such as job loss or medical issues.
- Bequest saving: Saving to leave an inheritance.

Real Interest Rate

The real interest rate (r) is the nominal interest rate (i) adjusted for inflation (π).
Higher real interest rates can encourage saving but may also lower the amount needed to save for a target goal.
Empirical data indicates that rising real interest rates have a modest positive effect on saving levels.

Psychological Factors Affecting Saving

Saving necessitates delaying current consumption, posing a challenge for those with self-control issues.
Financial arrangements like automatic savings plans can help overcome self-control difficulties.
Demonstration effect: Individuals may feel pressure to spend in line with peers, potentially impacting their saving behavior.

Household Saving in China

Chinese households save approximately 25% of disposable income, a significant increase from 10% in the late 1980s.
Saving behaviors are influenced by limited social safety nets and lack of borrowing opportunities.
Younger generations in China are generally wealthier than older ones, leading to higher saving rates.

Household Saving in the U.S.

The household saving rate ranges from 6% to 8%, lower than average international standards.
Contributors to low savings include:
- Government programs like Social Security and Medicare.
- Mortgages with minimal down payments.
- Confidence in future prosperity and asset appreciation.

National Saving

National saving is the difference between current income and spending on immediate needs.
It includes both private saving (by households and firms) and public saving (by the government).
Formula: National saving (S) = GDP (Y) - Current consumption (C) - Government spending (G).

Components of National Saving

Private saving: Includes household and business saving.
Public saving: Calculated as net taxes (T) minus government spending (G).
Government budget definitions:
- Balanced budget: T = G
- Surplus: T > G (public saving)
- Deficit: T < G (public dissaving).

Capital Formation

Investment refers to the creation of new capital goods and housing, primarily driven by firms.
The decision to invest is guided by the Cost-Benefit Principle, weighing the costs of capital against the benefits obtained.

Investment Decision Analysis

Example: Lauren’s lawn care business demonstrates the use of cost-benefit analysis to determine profitability and feasibility of investments.
Two critical costs in investment decisions are:
- Price of capital goods.
- Real interest rates, which raise overall investment costs when increased.

Supply and Demand for Savings

The supply of savings increases as the real interest rate rises; savings come from households, firms, and governments.
Demand for savings is inversely related to interest rates and reflects the borrowing needs for investment in capital goods.

Market for Savings

In a closed economy (no international borrowing/lending), the supply of and demand for savings must balance.
External factors, excluding interest rates, can shift the supply and demand curves for savings.

Technological Advances and Government Deficits

Technological improvements can lead to higher demand for investment by increasing capital productivity.
A government budget deficit decreases national savings and can lead to increased interest rates, crowding out private investment.
