How bad is time variability for users in mobility services?

摘要
This paper develops an expected-utility framework to quantify the cost of time (COT) and the cost of time variability (COTV), and derives tight upper bounds on COTV relative to COT under different preference and process assumptions; notable results include COTV/COT ≤ 1/2 for quadratic-utility users under a Poisson (exponential) service process and the general expression showing dependence on CV, relative risk aversion (RRA) and relative prudence (RP) [page::0][page::12][page::14]
