Which income concept serves as the primary basis for consumption decisions in Milton Friedman's Permanent Income Hypothesis?
Answer:
permanent income
Milton Friedman's Permanent Income Hypothesis posits that individuals base their consumption patterns on their expected long-term average income, known as permanent income, rather than their transitory or current income. This theory helps explain why consumption remains relatively stable even when current income fluctuates due to temporary shocks, as households smooth their consumption over their lifetime.
2
When individuals can effectively use borrowing and lending to smooth consumption over their lifetime, which metric best represents their standard of living?
Answer:
permanent income is a good measure of the distribution of living standards
The Permanent Income Hypothesis suggests that individuals base their consumption patterns on their expected long-term average income rather than temporary fluctuations. Since people can borrow during low-income periods and save during high-income periods, permanent income provides a more accurate reflection of an individual's true economic status and lifetime purchasing power than annual income.

What is the economic definition of permanent income?
Answer:
a person’s normal or average income
Permanent income is a concept introduced by Milton Friedman, representing the expected long-term average income of an individual. It suggests that consumption patterns are based on this stable, predictable level of income rather than temporary fluctuations, which are often saved or borrowed against to smooth consumption over time.
4
How does a period of unemployment caused by an economic recession typically impact a worker's income profile?
Answer:
reduce a worker’s current income but not necessarily their permanent income
According to the Permanent Income Hypothesis, individuals base their consumption on their expected long-term average income rather than transitory fluctuations. A recessionary period of unemployment causes a temporary drop in current income, but if the worker expects to return to employment, their permanent income—the discounted present value of expected future earnings—remains relatively stable. Thus, current income falls while permanent income is largely unaffected by short-term shocks.
