Effects of scale economies and production seasonality on optimal hub locations: the case of regional fresh produce aggregation

Interest in supporting local and regional food systems is rising and food hubs have attracted considerable attention among Federal, State, and local policymakers. This study explores the problem of endogenous hub location in fresh produce value chains in the Northeastern United States. To overcome limitations in the literature, we incorporate the effects of economies of scale and production seasonality into our models. Three experimental models are designed to examine the effects of alternatively applying yearly, quarterly, and monthly data on model solutions. We explicitly assess how interactions of scale economies and seasonality influence the structure and spatial attributes of an optimal regional produce aggregation hub system. The three models generate marketed different solutions and in many respects they lead to different conclusions about developing local/regional supply chains. The monthly model allows for production seasonality and actual hub operation cycle frequency and thus leads to more efficient hub solution with rich policy implications.

证券法上的民事责任功能研究

我国证券市场在短短十几年的时间内,在募集资金、推动国有大中型企业改制、优化资源配置等方面发挥了不可替代的重要作用.但不容乐观的是伴随着证券市场的发展各种违法违规现象在不断发生.尽管我国对证券违法行为明令禁止,并对严重的违法行为加以行政处罚甚至刑事制裁,然而证券市场上的违法行为仍然禁而不止.究其原因,除了管理层对证券市场发展的总体政策摇摆不定,监管者对违法行为处理不力等因素外,证券法上未建立完善的民事责任制度是重要的原因.本文从证券法上的民事责任功能的探讨入手,阐述了证券法上的民事责任具有的功能是证券刑事责任、行政责任所不能替代的原因,进而论证了建立完善的证券民事责任的必要性.
