Rationing and Rent Dissipation in the Presence of Heterogeneous Individuals
分析当消费者时间成本和个人估值不同时，排队配给的影响。研究发现，时间成本方差增大可能减少租金耗散，且引入二级市场不一定改善福利。
This paper discusses the implications of rationing by waiting when consumers have different time costs and personal valuation. The joint distribution function of time costs and personal valuations is used to characterize market equilibrium. It is argued that, under certain conditions, an increase in the variance of time costs will reduce the dissipation of rent. Furthermore, it is shown that introducing a secondary market for a rationed good does not necessarily improve welfare because total surplus under rationing by waiting depends more on the variance than on the level of time costs and personal valuation. The model is also used to discuss other institutions that involve rent-seeking activities, such as the patent system and import quotas. Copyright 1989 by University of Chicago Press.
