28. Correct. The answer is false. In a bilateral monopoly both players (seller and buyer) desire the same quantity only if the slopes of the MC and the MRP are equal in absolute value. Suppose that the monopsony buyer has MRP = a - bL and the monopoly seller has marginal cost of MC = c + dL. The monopoly seller wants to set her marginal revenue equal to marginal cost or a - 2bL = c + dL. Solving you get L_mp = (a - c)/(d + 2b). The monopsonist buyer wants to set MFC = MRP or a - bL = c + 2dL. Solving L_ms = (a - c)/(2d+b). L_mp = L_ms when b = d. Here they would want the same quantity but would negotiate on price. The price would be between their reservation prices P_rms and P_rmp, which are described in problems above.
