Answer:
Equilibrium Price FALLS and Equilibrium quantity RISES
Step-by-step explanation:
In an oligopoly generally, as more and more members enter into the industry, this signifies that supply will be increasing as there are now more sellers. The resultant effect clearly will be a price drop but not so clear is what happens to demand. It should be recalled however that a downward movement on the price (y) axis, will result in a forward shift in the quantity demanded (x) axis, implying a rise in quantity demanded as a response to the fall in price.
Another way to understand what happens in an oligopoly when more players enter the industry is to know that the equilibrium price of an oligopoly is a mid-point between that of the Monopoly (which is a higher price for a lesser quantity) and that of the Perfect Competition (lower price for higher quantity). So, as more players enter into an oligopoly; it pushes the equilibrium price of that oligopoly toward that of a perfect competition.
