25

26

The quantity of goods that producers are willing and able to make available for sale at each of possible prices during a specific period of time.
27
Law of Supply
As the price rises the quantity supplied rise. As the price falls the quantity supplied falls.
28
Change in the quantity supplied does what?
Involves movement along the supply curve due to a change in the price.
29
Change in supply.
The key idea is that costs are a major factor underlying the supply curve. Therefore anything that affects cost usually shifts the supply curve.
30
Define Surplus
When price is greater than market clearing price, suppliers are willing to supply more than the customer are willing to buy; hence, market shortage with is also known as excess supply.
31
Define shortage
When price is less than market clearing price, customers are willing to purchase more than the producers are willing to supply; hence, market shortage which is also known as excess demand.
32
Define equilibrium
By trial and error, market participants will eventually arrive at market clearing price. Only at this market clearing price that the quantity the producers are willing to produce is identical to the quantity consumers are willing and able to purchase.

No
37
Will a change in consumer tastes cause the demand for product K to change?
Yes
38

If products A & B are complements and the price of B decreases the:
Demand for A will increase and the amount of B demanded will increase.
40
