项目摘要
This NSF grant will explore urban goods movements, pricing, and social justice through numerical experiments. The experiments will be based on a new family of urban freight models, in lieu of expensive field measurements. The models will be used to investigate five primary hypotheses: (1) urban freight quality of service may be enhanced through traffic network and route reconfiguration; (2) urban neighborhoods with persistent, chronically inferior urban freight service sometimes emerge spontaneously, but their impact may be substantially ameliorated through incentivizing and subsidizing freight service providers; (3) the present demand for goods provisioned by large, publicly traded electronic retailers might not be sustainable because of their current use of internal subsidies and hidden costs to fund extremely low shipping fees, creating an unfunded liability through which investors sacrifice profits for market share; (4) when subsidies are scaled down and hidden shipping costs are made explicit, deleterious impacts on carriers, e-retailers and households may arise; and (5) food underserved areas (FUAs) arise from the combination of relatively low demand for and relatively high supply chain costs of healthy food items - creating a food dessert that represents a serious social injustice to members of society who cannot find alternative sources of affordable, quality food.The intended family of urban freight models will be explicitly dynamic and based on game theory. The models will depict the role urban freight systems in electronic commerce at the household level, including explicit recognition of food deliveries. A careful experimental design will be followed in assessing the aforementioned hypotheses. Accordingly, the intended family of models, as well as the experiments to assess hypotheses, will address the following considerations: (1) urban freight carriers compete with one another, not only for market share but also for urban routes and parking that are also valued by commuters and hired ride services; (2) there is an undeniable dynamic aspect to the flows of vehicles and consumption goods over metropolitan road networks; moreover, those flows involve multiple time scales that make the comparative statics paradigm nearly meaningless; (3) in an effort to be competitive, electronic retailers (e-retailers) are drawn into pricing games that purposely blur the distinction between delivery fees and the prices of purchased goods, with the consequence that it is necessary to simultaneously model both freight service and urban goods provisioning; (4) indirect evidence exists that pricing strategies employed in e-commerce do not fully cover delivery costs; (5) some electronic retailers offer discounted and promotional shipping rates, creating unfunded liabilities that bring into doubt both the medium- and long-term sustainability of their core transactions; and (6) there is a gap between the demand for healthy foods and the minimum order size that makes it worthwhile for food purveyors to deliver to certain neighborhoods, thereby creating food underserved areas.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
NSF的这项资助将通过数值实验探索城市商品流动、定价和社会正义。这些实验将基于一系列新的城市货运模型,而不是昂贵的实地测量。模型将被用来研究五个主要假设:(1)城市货运服务质量可以通过交通网络和路线重构来提高;(2)城市货运服务质量持续低下的城市街区有时会自发出现,但它们的影响可以通过激励和补贴货运服务提供商来大大改善;(3)目前对大型公开交易电子零售商供应的商品的需求可能无法持续,因为它们目前使用内部补贴和隐藏成本来支付极低的运费,造成了一种无准备金的负债,投资者通过这种负债牺牲利润来换取市场份额;(4)当补贴减少,隐藏的运输成本被公开时,可能会对承运人、电子零售商和家庭产生有害影响;以及(5)食品服务不足地区(FUA)是由于健康食品的需求相对较低和供应链成本相对较高-创建一个食品甜点,代表了严重的社会不公正的社会成员谁不能找到替代来源的负担得起的,优质的食物。家庭的城市货运模型的预期将明确动态和基于博弈论。这些模型将描述城市货运系统在家庭一级电子商务中的作用,包括明确承认食品运送。在评估上述假设时,将遵循仔细的实验设计。因此,预期的模型系列以及评估假设的实验将解决以下问题:(1)城市货运公司相互竞争,不仅是为了市场份额,而且是为了城市路线和停车,这也是通勤者和出租车服务所重视的;(2)城市道路网络上的车辆和消费品流动具有不可否认的动态方面;此外,这些流动涉及多个时间尺度,使得比较静态范式几乎毫无意义;(3)为了具有竞争力,电子零售商(电子零售商)被卷入定价游戏,故意模糊送货费和购买商品价格之间的区别,结果是有必要同时模拟货运服务和城市商品供应;(4)有间接证据表明,电子商务中采用的定价策略并不能完全覆盖交付成本;(5)一些电子零售商提供折扣和促销运费,造成无准备金负债,使人对其核心交易的中期和长期可持续性产生怀疑;以及(6)在对健康食品的需求和最小订单大小之间存在差距,使得食品供应商值得向某些社区交付,该奖项反映了NSF的法定使命,并通过使用基金会的知识价值和更广泛的影响审查标准进行评估,被认为值得支持。
