The Problem of Unexpected Income Shocks in the Life Cycle Model

Lifetime Consumption Planning

An individual expects to live for two periods. In the first period, they will earn an income of $100,000. In the second period, they will be retired and earn no income. According to the idealized model where the individual has perfect foresight and aims to smooth their consumption perfectly, what will their level of consumption be in the first period?

Saving and Borrowing Behavior

Consider an individual who has perfect foresight of their entire lifetime income, which will be low during their youth, peak in middle age, and fall to zero in retirement. According to the idealized model of consumption smoothing, this individual's level of consumption should also peak during their middle-aged, high-income years.

Consider an individual whose income is low during their early career, peaks in middle age, and is zero during retirement. If this individual has perfect foresight of their lifetime earnings and adheres strictly to the idealized model of consumption smoothing, which statement best describes their financial behavior over their life?

Comparative Consumption Smoothing Analysis

An individual's income is expected to be low during their early working years, rise to a peak in middle age, and then fall to zero during retirement. Assuming this individual has perfect foresight and aims to maintain a perfectly constant level of consumption throughout their entire life, which of the following best describes the relationship between their income and consumption curves when plotted against age?

An individual has perfect foresight of their lifetime income, which is low in their youth, high in middle age, and zero in retirement. They calculate a plan to maintain a perfectly constant level of consumption. Now, suppose they learn that their middle-age income will be significantly higher than they initially anticipated, while their youth and retirement incomes remain unchanged. How should this new information affect their financial behavior during their youth?

An individual has perfect foresight of their lifetime income, which is low during their early career, peaks in middle age, and is zero during retirement. They plan to maintain a perfectly constant level of consumption throughout their life. Match each life stage with the corresponding financial behavior and the relationship between income (Y) and consumption (C).
