报告内容摘要
Conventional wisdom suggests that capacity expansion could increase (at least not decrease) firms’ profit. This paper shows that this is not hold for 3D printing product in a setting with two competing firms. We develop a game model in which two firms have chance to produce 3D-printing products by investing in 3D printing. The 3D-printing product is more valuated by consumers than the traditional product. Nevertheless, the disadvantages of the 3D-printing product are that the capacity is limited relative to the traditional product and the firms usually spend a fixed cost. We first analyze the case of monopoly which is served as a benchmark. Then, we examine the competing case in which we characterize the equilibrium3Dprinting strategy for the two firms. In the case of monopoly, it is intuitive that the firm can be benefit from 3Dprinting if the fixed cost is not too high. However, in the competing case, it is interesting that the two firms may be involved into a prisoner’s dilemma. That is the optimal strategy for each firm is to give up 3D printing, but the equilibrium strategy is to embrace 3Dprinting. Furthermore, we find the firm gains more profit (not strictly) in the monopoly case as the capacity of 3D printing increasing. In the competing case,surprisingly, we find thatone firm’s profit may decease as the capacity increases. At last, we verify the robustness of the model and find the main findings are valid even if the assumptions are relaxed.
