According to the Keynes saving is a function of what?

According to Keynes, saving is primarily a function of income. He posited that as income increases, individuals tend to save a portion of that income rather than spending it all. This relationship is captured in his concept of the marginal propensity to save, which indicates that the proportion of additional income saved varies with different income levels. Additionally, Keynes emphasized the importance of psychological factors and expectations in influencing saving behavior.
