Household Saving Motives: Interest, Inflation, and Income Stability

Steps:

• High interest rates increase returns on savings, incentivizing households to save rather than spend.
• Low inflation maintains the real value of saved money, making saving more attractive.
• Low unemployment signals stable income, reducing the need to spend savings on emergencies and boosting precautionary saving.
• Combine these: optimal conditions for higher saving propensity.

Why C is correct:

• Aligns with the substitution effect in consumption theory, where high real interest rates (high nominal rate minus low inflation) raise the opportunity cost of current consumption, per the life-cycle hypothesis.

Why the others are wrong:

• A: High unemployment creates income uncertainty, prompting households to spend savings instead.
• B: High unemployment overrides high interest benefits, leading to precautionary dissaving.
• D: Low interest rates reduce saving returns, discouraging accumulation despite stability.

Final answer: C
