Document Summary

Change in quantity demand - movement along same curve (price) Change in demand - curves shifts to the left or right (anything besides price) Determinate of demand (shift) 1. tastes/preferences 2. prices of related goods (complements or substitutes) 3. income 4. consumer s expectations of the future. Law of supply - positive correlation between price and quantity supplied. How much sellers want to sell depends on the price. Supply function is an equation which shows the relationship between the price and quantity supplied. Change in quantity supplied (price) cause charge along the same curve. Change in supply - supply curve shifts depending on factors. Difference between price of good and cost per unit = profit. Shifts bc 1. increased cost of production 2. technology 3. sellers expectations of the future 4. number of producers (more produce - supply increases) Quantity supplied and quantity demanded equal out.

b. both a change in quantity supplied and a change in supply are movements along the supply curve, only in different directions.
c. a change in quantity supplied is a movement along the supply curve, and a change in supply is a shift of the supply curve.

Question 2
What is the difference between a shortage and scarcity?
Choose one answer.
a. Scarcity will always exist because choices must be made, but a shortage will only exist if the price is kept below the equilibrium level.
b. Scarcity is a result of two or more alternative uses and will always exist, and quantities of supply and demand adjusting to flexible prices will create shortages.
c. A surplus will exist when a good is scarce; a shortage merely implies that there isn't as much of something as people would like, which is nearly always the case.
