Consider three firms producing the same good in a market competing a la Bertrand. They face an inverse demand function Q(p) = 10 – P Which of the following is FALSE? For these problems assume no firm has a fixed cost. A If each firm's marginal cost is $5, the equilibrium price paid by consumers is 5. B If a firm leaves the market and their marginal cost is higher than the Nash Equilibrium Price, the Nash Equilibrium will not change.

inverse demand function
Q(p) = 10 – P
Which of the following is FALSE? For these problems assume no firm has a fixed cost.
A If each firm's marginal cost is $5, the equilibrium price paid by consumers is 5.
B If a firm leaves the market and their marginal cost is higher than the Nash Equilibrium Price,

C The Nash Equilibrium will always be equal to some firm's marginal cost.
D If each firm's marginal cost is $5, the equilibrium quantity consumed is $5.
E If two firms have a marginal cost of 3, and a firm has a Marginal Cost of 3.5, there are multiple
Nash Equilibria.
