Why does the demand curve slope downward?  Why does the supply curve slope upward? Given the demand and supply schedules below:

 Price (dollars per CD) Quantity Demanded (per day) Quantity Supplied (per day) 5.00 300 100 6.00 250 150 7.00 200 200 8.00 150 250 9.00 100 300

What is the market equilibrium?

If the price of CD is \$6.00, describe the situation in the CD market. Explain how market equilibrium is restored.

A rise in incomes increases the quantity of CDs demanded by 100 a day at each price. What is the new equilibrium and how does the market adjust?

A rise in the number of recording studios increases the quantity of CDs supplied by 75 a day at each price. People download more music from the Internet and the quantity demanded of CDs decreases by 25 a day at each price. With no change in incomes, what is the new equilibrium and how does the market adjust?

Supply: Supply of a good or service refers to the different combinations of prices and the output that producers are willing and able to sell at respective prices. The supply curve slopes upwards indicating that a higher price would correspond to higher supply. The following figure shows a typical demand curve and supply curve.

Step 3

a) The demand curve slopes downward because of law of demand. Law of demand states that ceteris paribus (other things being constant), a rise in the price of a good leads to decrease in the quantity demanded for that good. That is, the quantity demanded of a good and its own price vary inversely.
