Answer:
b
Explanation:
when firms enter into an industry, there are more firms competing for customers. This would shift the demand curve to the right as supply increases. An increase in supply would lead to a reduction in price.
If firms leave the industry, there would be a reduction in supply and price would increase
Answer: False
Explanation:
Shoes and socks are complementary goods. A complementary good is a good that the demand for the good increases when there is reduction in price of its complement. Complementary goods have a negative cross elasticity of demand i.e. the demand for the good rises when the price of the other good decreases. Assuming "A" is a complement to "B" , a rise in the price of "A" will have a negative effect on the demand for "B".
A reduction in the price of A leads to a positive outcome on the demand for B resulting in an outward shift of its demand curve. The quantity demanded of one good has a direct relationship on the quantity demanded of the other good as they are linked together. When the price of shoes increases, less of socks will be demanded and vice versa.
