An incumbent monopoly with constant marginal cost k operates in a market with demand schedule p = a-Q where p is the price Q is the quantity demanded and a > k is a positive parameter. A second rm (with the same constant marginal cost k) wishes to compete for demand but faces a fixed cost F to enter the market. In order to deter entry the incumbent decides to precommit to producing a certain capacity G thus incurring a sunk cost kG which cannot be recovered.Determine the critical value of the fixed cost F-bar where the optimal strategy for the incumbent is to deter when F > F-bar and to accommodate when F
