1. In addition assume that firms target own profit maximisation, compete (simultaneously) in quantities and have marginal costs equal to ci = c2 = c. Assume that 1 > c > 0. Describing the necessary mathematical steps and providing the related economic intuition,

1. find and describe the inverse demands faced by the two firms (HINT: solve the two demands simultaneously with respect to prices) [15 marks] 2. derive and describe each firm’s best response function. Are quantities strategic substitutes or complements? [25 marks] 3. derive and describe the equilibrium quantities [30 marks] 4. explain the economic intuition behind parameter a. What happens to the equilibrium quantities and profits if a increases? Provide economic intuition. [30 marks]
