What factors influence consumption expenditures according to the Keynesian income-expenditure model?

The most important determinant of consumption expenditures in the Keynesian income-expenditure model is disposable income.

The Keynesian income-expenditure model, developed by John Maynard Keynes, emphasizes the significance of disposable income in determining consumption expenditures. Disposable income refers to the amount of money that individuals have available to spend or save after paying taxes and other mandatory expenses. In this model, consumption expenditures are heavily influenced by changes in disposable income.

Keynesian economics focuses on short-run relationships between total spending and real GDP, particularly in the context of fluctuating market conditions. The model highlights the importance of adjusting goods and services to match consumer demand, as ultimately, the economy will only produce what can be sold in the market.

As disposable income increases, individuals have more funds at their disposal, leading to higher consumption expenditures. This concept underscores the idea that consumer spending is directly linked to income levels, as posited by Keynesian economics.
