Endogenous Quality Differentiation in Congested Markets
研究了在存在拥挤外部性的市场中，企业如何通过定价内生地实现质量差异化，从而让不同顾客自选价格-质量组合，并提升效率。
Firms selling a product with congestion externalities to a heterogeneous population of customers have an incentive to offer differentiated levels of quality. In a price competitive market, differentiation arises endogenously through the prices chosen by firms. In equilibrium, firms offer a range of prices, which induce an efficiency improving range of quality levels and allow customers to self-select their preferred price-quality combinations. Additional results suggest that, with many firms in the market, the choice of prices dominates the choice of service capacities in determining congestion levels.
