Life Cycle Model of Consumption
The life cycle model of consumption is a framework explaining how individuals plan their spending over their entire lifetime to maintain a stable standard of living. It posits that consumption decisions are based not just on current income, but also on expected future income and accumulated assets. A typical application involves a person borrowing in their youth (e.g., for education), saving during their peak earning years, and drawing down those savings during retirement when their income is lower. This model focuses on smoothing consumption over predictable life stages.

Consider two individuals, Alex and Ben, who both live for two periods. Alex earns $50,000 in the first period and $50,000 in the second. Ben is a student in the first period and earns $10,000, but he will graduate and earn $90,000 in the second period. Both have access to a credit market to borrow and save. Assuming both individuals prefer to maintain a stable level of spending across both periods, which of the following outcomes is most likely?

Evaluating the Limits of Consumption Smoothing
An individual who typically earns a stable annual income receives a large, unexpected, one-time cash bonus. According to the principle that the satisfaction gained from an additional dollar of spending decreases as total spending increases, how is this individual most likely to adjust their consumption?
Rationale for Future-Oriented Borrowing
Individuals often try to maintain a stable level of consumption over time, despite changes in their income. Match each individual's scenario to the most likely financial strategy they would use to achieve this goal.
In an economy where most households successfully maintain a stable level of consumption despite income fluctuations, a temporary, government-issued tax rebate is likely to cause a large and immediate increase in overall consumer spending.
Life-Cycle Financial Strategy
An individual plans their finances over their entire life to maintain a relatively consistent level of spending, despite their income changing significantly. Arrange the following financial stages into the most logical chronological order based on this goal.
Consider two hypothetical economies. In Economy X, households have limited access to borrowing and saving, causing their spending to be highly dependent on their current income. In Economy Y, households have widespread access to financial tools that allow them to save and borrow easily, enabling them to maintain stable spending levels regardless of short-term income changes. If both governments enact an identical, one-time stimulus payment to every household, which statement best analyzes the likely outcome?

A 40-year-old individual has been consistently saving a portion of their income. They receive credible news that their industry will face a major downturn in 10 years, significantly reducing their expected income during the last 15 years of their career before retirement.

Applying the Lifetime Consumption Framework
Consider two individuals, both earning the same modest annual income. Individual A is a 25-year-old medical resident who anticipates a significant increase in salary upon completing their training in a few years. Individual B is a 60-year-old factory worker who is approaching retirement and expects their income to decrease.
