Optimal Use of Scale Economies in the Federal Reserve's Currency Infrastructure
研究美联储能否通过重新分配高速货币清分量来降低整体处理成本，模型在维持服务水平的同时优化清分量的空间分布，发现大部分潜在节约无需关闭现有站点，在菲尼克斯设新站可进一步降本。
Could the Federal Reserve lower its overall currency processing costs by reallocating its high-speed currency sorting volume? Given estimates of currency shipping costs and scale economies for high-speed sorting, the authors? model minimizes costs by optimal distribution of sorting volumes across possible processing sites, while maintaining levels of service to depository institutions. Their key findings are that most of the potential savings can be achieved without closing any existing processing sites and that locating a new site in Phoenix would help lower System processing costs.
