6.1. the inverse market demand curve for a duopoly market is p = 14 - q = 14 - q1 - q2, where q is the market output, and q1 and q2 are the outputs of firms 1 and 2 respectively. each firm has a constant marginal cost of 2 and a fixed cost of 4. consequently, the nash-cournot best-response curve for firm 1 is q1 = 6 - q2/2. a. create a spreadsheet with columns titled q2, br1, q, p, and profit. in the first column, list possible quantities for firm 2, q2, ranging from 0 to 12 in increments of 2. the column headed br1 shows the profit-maximizing output (best response) for firm 1 given firm 2’s output in the first column. the q column sums the values in the q2 and br1 columns. the p column lists the price that corresponds to q. the profit 1 column shows the profit of firm 1, taking account of its marginal and fixed costs. after filling in the spreadsheet, use the scatterplot option in excel to draw the best-response curve for firm 1. b. what is the monopoly output and profit for firm 1
