AVERAGE PROPENSITY TO CONSUME

8 五月, 2015 - 11:48

The willingness to use a proportion of income (Y) for consumption (C) is known as average propensity to consume (APC): APC=C/Y As income increases, the average propensity to consume decreases. This is indeed observable in the fact that wealthy individuals consume a smaller proportion of their income than to poorer people who may in fact be force to receive money from others.

If the income of a family is $50,000 and that family spends $45,000 per year, the average propensity to consume is APC = 45,000/50,000 = .9 or 90%.
