Document Summary
Amount of a good or service that consumers want to purchase. Not necessarily how much they are able to actually purchase. Price and qd are negatively related holding all other factors constant (ceteris paribus) Other examples: status goods (conspicuous consumption) A change in a variable other than a product"s own price will cause a shift in demand. Normal good qd increases when income increases. Inferior good qd decreased when income increases.

Good y is a complement for good x when demand for good x decreases when the price of good y increases. Qs is the amount of good or service that producers want to produce at a given price.
