Document Summary

Demand ; how much people actually value that good. When price in good changes, demand curve goes up and down. When cheaper good comes out that is subsitute, demand for normal good goes down. Expectation that the price is going to go up later ; increases demand at the moment. Changes in cost of producing good ; changes supply curve. If price of the good changes, curve does not move ( only up and down) If anything other than the price changes, then the curve moves (shifting) ; change in demand and supply. No one changes price or demand ; market equlibrium. Price on y axis, 2 types of graphs downward slope for demand vs price , upward slope for supply vs price. To solve for equlibrium , just set the market demand and market supply equal to each other . Inverse demand and supply ; quanity depends on price .

When quantity demanded decreases in response to a change in price,

A. the demand curve shifts to the right.
B. the demand curve shifts to the left.
C. there is a movement down along the demand curve.
D. there is a movement up along the demand curve.
E. the supply curve shifts to the right.

The price elasticity of demand is the measure of the responsiveness of the demand for a good to a percentage change in the price of that same good. When the demand for a good changes due to an increase or decrease in the price of the good, it can be said that the good has a price elastic demand. On the other hand, a good whose demand is not significantly affected by a change in the price levels is price inelastic. For example, luxury goods are usually price elastic because these are not something that most people really need. Thus, when the price of luxury goods increases, the demand for such goods falls. Goods that fall within the latter category are usually the basic necessities such as food and prescription medicine. Even when these types of goods become pricier, most people would find ways to afford them because they need those items to survive.
