The effects of Mongolia's booming mining industry on its agricultural sector: A test for Dutch disease

Dutch disease occurs when currency strengthening associated with a booming sector of an economy crowds out a lagging trade‐dependent sector. In this study, a Keynesian‐style model is specified to deduce hypotheses about how increased foreign direct investment (FDI) aimed at Mongolia's mining sector affects its agricultural sector. A key finding is that while econometric results suggest the increased FDI strengthened Mongolia's currency, its adverse effect on Mongolia's trade‐sensitive agricultural sector is not sufficiently strong to cause the sector to decline. Although Dutch disease was not detected, the posited mechanism clearly is important. Specifically, when currency strengthening is ignored the reduced‐form elasticity of agricultural value‐added with respect to FDI is 2.7 times larger than when currency strengthening is taken into account (0.103 vs. 0.038). Also, FDI‐induced currency strengthening causes the Keynesian multiplier to drop from 2.40 to 2.00 and the FDI multiplier to drop from 3.05 to 1.89.

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.     

LC-MS检测奶粉中的三聚氰胺

三聚氰胺是一种重要的氮杂环有机化工原料,由于三重四级杆质谱仪具有多反应监测(MRM)的扫描模式,能够很好地去除基质干扰,因此能够定量检测微量的三聚氰胺。     

供给侧改革背景下我国金融监管体制重构的思考——基于互联网金融对传统金融的冲击分析

近些年来,混业经营已成为金融市场发展的趋势。其中,以互联网金融为代表的混业经营正在加速推进混业监管的进程。而中国金融监管制度停留在分业监管的阶段,不利于金融市场的趋良性发展。可见,金融监管制度改革已经迫在眉睫。金融市场的混业经营将倒逼金融混业监管,互联网金融的快速发展也将更加需要混业监管。文章首先纵观国外金融监管改革路径并进行对比分析;接着构建金融监管演进的数学模型进行推理,得出金融监管改革不仅是金融混业经营发展所推动的结果,而且是金融监管制度演进的必然选择;混业监管对于金融监管主体和金融经营者而言,是一种"双赢"策略。在此基础上,提出建立金融监管磋商会议制度构想。最后在构建系统性金融监管体系、分层次推进混业监管改革、坚持以市场的运行为导向以及形成综合性风险控制体系等方面提出建议。     

我国商业银行开展福费廷业务的现状及对策

福费廷业务具有独特的风险防范和融资功能,可以解决出口企业应收账款问题,使银行稳定客户、增加收益。在我国,福费廷业务还属于新兴业务种类,发展不够完善。但是随着市场需求的进一步增加和竞争压力,福费廷业务必然有广阔的前景,我国的商业银行要正视业务发展中存在的主要问题并认真加以解决,利用本土化优势扩展市场份额,提高国际竞争力。

基于内外因素整合视角下深度贫困地区农户多维贫困测度与分析——以新疆南疆三地州为例

文章根据马克思的内外因理论,从内外因素整合视角出发,构建农户多维贫困指标体系,以2017年新疆南疆三地州的农户调研数据为样本,采用A-F方法对深度贫困地区农户多维贫困进行测度与分解。结果表明,南疆三地州农户在参与新型农业经营主体、职业技能培训、公共交通服务和疾病等方面贫困特征明显,面临多维贫困问题;多维贫困发生率高达54.9%,多维贫困指数为23.58%。多维贫困指数按指标分解显示,职业技能培训、参与新型农业经营主体和疾病是导致农户多维贫困的主要内部原因,而公共交通服务是其主要外部原因;按是否收入贫困农户分解显示,非收入贫困农户也面临着多维贫困问题。
