To bundle or not to bundle
研究当捆绑销售能降低消费者估值分散度时，垄断企业是否应选择捆绑而非单独销售，发现边际成本低或估值分布集中时捆绑更优。
Commodity bundling is studied in an environment where the dispersion of valuations un-ambiguously decreases when two or more goods are sold as a bundle only. Bundling is more likely to dominate separately selling the goods if marginal costs are low relative to the average valuation, or if the distribution of valuations is very peaked around the mean.
