초록

In this study, we examine the pricing strategy between manufacturers competing in both vertically differentiated main and aftermarket, and numerically analyze the equilibrium solutions to provide meaningful implications for decision-making regarding the aftermarket. To do this, we first use a market model that reflects the fact that, in the aftermarket, some preference may occur for the same brand as the product selected in the main market. We also used a Super game to derive the optimal pricing method between the manufacturers. The results showed that there is a difference in the preferred pricing method between the manufacturer selling high-quality products and the manufacturer selling low-quality products. The low-quality manufacturer prefers to determine the prices of the main product and aftermarket product in an integrated manner rather than independently, but the high-quality manufacturer shows no difference in preference between independent or integrated methods. In addition, it was found that the high-quality manufacturer earns profits from both main and aftermarket, whereas the low-quality manufacturer almost gives up main market profits and focuses on the aftermarket profits.
