Bundling and International Market Segmentation
通过一个简单模型说明，企业将产品与不可贸易品捆绑销售，可能导致国际寡头市场分割，使得同质产品市场整合带来价格均等化，但捆绑产品市场整合对经济毫无影响。
The paper shows how firms, by bundling their products with nontradables, may contribute to the segmentation of international oligopoly markets. We develop a simple example with two products: one that is homogeneous across markets, and one that is bundled with a nontradable, e.g., local services. Integration of the markets for the homogeneous product yields the expected price equalization across markets. However, integration of the markets for bundled products leaves the economy entirely unaffected. Hence, the standard methodology of comparing a segmented and an integrated equilibrium would exaggerate the effects of integration in this economy.
