Postal reporting method overhaul
The Postal Service proposes changing how it calculates window service costs by correcting mathematical and econometric errors and by using modern point-of-sale (RSS) data and Stochastic Frontier Analysis (SFA). The proposal updates visit time, network, waiting time, and non-acceptance variabilities and is intended to reduce the reported volume-variable window service costs.
Lower reported window-service unit costs
The Postal Service says the proposed methodology would lower reported unit window-service costs for many products. Examples in the filing: First-Class Mail unit window-service cost falls from $0.007 to $0.003 (−$0.004); USPS Marketing Mail from $0.002 to $0.001 (−$0.001); Periodicals from $0.0014 to $0.0006 (−$0.0008); Package Services from $0.049 to $0.028 (−$0.021); Domestic Competitive Products from $0.096 to $0.049 (−$0.047); Certified Mail from $0.652 to $0.431 (−$0.221); and Money Orders from $2.032 to $0.978 (−$1.053).
