Life-Cycle Hypothesis (LCH)

The life-cycle hypothesis (LCH) is an economic theory that describes how people make financial decisions over their lifetime. The LCH is based on the idea that people have a finite amount of time and money, and they must make choices about how to allocate these resources in order to maximize their well-being.

The LCH divides a person's life into three stages:

* **The accumulation stage:** This is the stage of life when people are working and earning money. During this stage, people save for retirement and other long-term goals.
* **The decumulation stage:** This is the stage of life when people are retired and no longer working. During this stage, people withdraw from their savings to support their living expenses.
* **The transition stage:** This is the stage of life when people are between the accumulation and decumulation stages. During this stage, people may be saving for retirement, but they may also be withdrawing from their savings to support their living expenses.

The LCH predicts that people's saving and spending behavior will change over their lifetime in response to changes in their income and wealth. For example, people are more likely to save during the accumulation stage when they have a higher income and less likely to save during the decumulation stage when they have a lower income.

The LCH has been used to explain a variety of financial phenomena, such as the relationship between age and savings, the gender gap in savings, and the retirement savings crisis.

The LCH is a useful tool for understanding how people make financial decisions over their lifetime. However, it is important to note that the LCH is a theory, and it is not always accurate in predicting people's actual behavior.
