Why is the demand curve downward sloping?

Posted on April 15, 2014 at 9:10 AM

The demand curve slopes downward for the following three reasons:


1. Law of diminishing marginal utility - As you purchase an additional unit, your additional satisfaction decreases. Therefore, the price must fall for you to want to purchase more.

2. Substitution effect - As the price of a good increases, you look for cheaper alternatives to purchase.

3. Income effect - As the price of a good increases, your income has less purchasing power and you cannot afford to purchase as much.
