Nonlinear Pricing and Misallocation
研究非线性定价如何影响加成率和资源错配，发现高品味消费者被分配过多商品而低品味消费者过少，这种跨消费者的错配福利损失远大于线性定价下跨企业的错配。
This paper studies the effect of nonlinear pricing on markups and misallocation. In a general equilibrium model in which firms are allowed to set a quantity-dependent pricing schedule, markup heterogeneity is not a sign of misallocation. Instead, we point to a new source of misallocation: high-taste consumers are allocated too much of each good, low-taste consumers too little. Using micro data from the retail sector, we show that nonlinear pricing is prevalent and quantify the model. Welfare losses from misallocation across consumers are substantially larger than those from misallocation across firms under linear pricing.
