Assume now that firm 0 may invest the sum K >0 to improve the quality of its good, so that consumers will value its good twice as much as the rival's value, that is the valuation consumers give of the good produced by firm 0 is 2 v. 4) Determine the marginal consumer who determines the demand for both firms. 5) Find the equilibrium prices, quantities and profits. 6) Denote by $K_{max}$ the maximal value of K such that firm 0 wants to make the investment. Find $K_{max}$. 7) When K > $K_{max}$, is there any chance that the investment is undertaken by firm 0? (Hint: you may want to calculate the effect of the investment on the profits of firm 1).
