aggregate consumption

In economics, aggregate consumption refers to the total spending by households on goods and services. This spending is a crucial driver of economic activity, accounting for a significant portion of a country's Gross Domestic Product (GDP).1

The consumption function describes the relationship between consumer spending and the factors that influence it. These factors can include income, wealth, interest rates, and consumer expectations about the future. Economists use theories like the life-cycle hypothesis and the permanent income hypothesis to understand how individuals make spending decisions over time. Understanding aggregate consumption is vital for analyzing both short-term economic fluctuations, like the business cycle, and long-term economic growth.21
