• Y-axis= Price • X-axis= Quantity • A change in price of a good causes a movement along the demand curve. • A change in any variable that affects demand—except for the good’s price—causes the demand curve to shift. • An increase in income will INCREASE demand (shift curve rightward) for a normal good, and DECREASE demand for an inferior good. • A rise in the price of a substitute INCREASES the demand for a good (shift curve rightward) • A rise in the price of a compliment DECREASES the demand for a good (shift curve leftward) • The law of supply states that when the price of a good rises, and everything else remains the same, the quantity of the good supplied will rise • Each point on a supply curve shows the quantity that sellers would choose to sell at a specific price • Everything but good’s price causes a shift in supply curve • When the price of an alternative rises, the supply curve shifts leftward • An INCREASE in sellers—with no other change—shifts the supply curve rightward
