A linear cost function is C(x) = 2x + 400. (Assume C is measured in dollars.) (a) What are the slope and the C-intercept? slope 2 C-intercept 400 (b) What is the marginal cost MC ? MC = What does the marginal cost mean? If production is increased by this many units, the cost increases by $1. Each additional unit produced reduces the cost by this much (in dollars). If production is increased by this many units, the cost decreases by $1. Each additional unit produced costs this much (in dollars). (c) What are the fixed costs? $ (d) How are your answers to parts (a), (b), and (c) related? slope = fixed costs, and C-intercept = marginal cost C-intercept slope = marginal cost slope C-intercept = marginal cost slope = marginal cost, and C-intercept = fixed costs (e) What is the cost of producing one more item if 50 are currently being produced? $ What is the cost of producing one more item if 100 are currently being produced? $

Suppose the marginal damage and marginal benefit curves in a polluted neighborhood are md = p/3 and mb = 4 – p. also, suppose that transactions costs are low, so that the consumers and the firm can bargain. we saw that in this case, the socially-optimal level of pollution is achieved. start by computing the socially-optimal p. then, for each of the following cases, compute the amount of money transferred through the bargaining process, and indicate who pays whom (i.e., whether consumers pay the firm, or vice versa). also, compute the gains to each party relative to the status quo (i.e., the starting point of the bargaining process).a)consumers have the right to clean air; firm is dominant in the bargaining process.b)consumers have the right to clean air; consumers are dominant in the bargaining process.c)firm has the right to pollute; firm is dominant in the bargaining process.d)firm has the right to pollute; consumers are dominant in the bargaining proces
