研究免费接入的拥堵设施在容量和需求随机波动时,信息对用户参与决策的影响,发现需求弹性小于1时最优设计容量随波动增大而增大,且信息通常提升福利,但在非恒定弹性下可能降低福利。

Abstract

We investigate the effect of information on users' participation decisions at a free-access congestible facility that is subject to unpredictable fluctuations in capacity and demand. With demand isoelastic in user cost, and user cost isoelastic in the ratio of demand to capacity, optimal design capacity is larger with mean-preserving spreads in capacity and demand if and only if demand elasticity is less than one. Expected welfare is greater with better information. Interestingly, with nonconstant elasticity demand and/or user costs, information can be welfare reducing.
