#16
What is the difference between a change in quantity demanded and a change in demand?
A change in quantity demanded is caused by a shift in the demand curve, while a change in demand is caused by movement along the demand curve
A change in quantity demanded is caused by a shift in the supply curve, while a change in demand is caused by movement along the demand curve
A change in quantity demanded is a movement along the demand curve due to a change in price, while a change in demand is a shift of the entire demand curve due to factors other than price
A change in quantity demanded occurs in the short run, while a change in demand occurs in the long run

Normal goods have a high price elasticity of demand, while inferior goods have a low price elasticity of demand
#18
