‘In England,they don’t call you black!’ Migrating racialisations and the production of Roma difference across Europe

This article draws on long-term fieldwork among Slovak Roma migrants, identifying processes through which a haunting figure of the Roma migrant emerges across Europe, to argue for more differentiated accounts of continuing and emerging forms of racialisation. It explores how the movement of Roma (whose bodies are marked by their racialised ‘darkness’ in Slovakia) to Britain granted them a temporary escape from this modality of branding while simultaneously exposing them to different categorisations within a re-configuring classificatory matrix. The article develops the concept of ‘migrating racialisation’ in order to empirically trace how historically developed forms of racialisation in Slovakia migrate across Europe through the movement of Roma and non-Roma migrants from Eastern Europe, as well as through particular forms of knowledge circulating within transnational fields constituted not only by Roma migrants themselves but also by various institutions for ‘managing’ or ‘researching’ ‘the Roma’. This concept allows us to analyse how the recent forms of racialisation simultaneously draw on heterogenous histories and nation-state formations, social conditions and sedimented bodily dispositions, which are re-adjusted to new social conditions, discourses and emerging forms of knowledge produced about Roma migrants over the last decade in British and European contexts.     

区域一体化背景下城市土地利用效率的空间关联及其解释——以长江中游城市群为例

从理论层面揭示区域一体化影响城市土地利用效率（ULUE）的内在机理，构建区域一体化背景下“规模+结构+集聚”的ULUE测度体系，并综合利用小波神经网络、空间分异模型和空间回归分析探索2003-2015年长江中游城市群ULUE的空间关联特征及其影响因素。结果发现：①区域一体化背景下长江中游城市群ULUE从2003的0.561 4增长至2015年的0.811 1，且呈现出明显的区域差异。②ULUE并非随机分布，而是具有空间上的关联特征和集群趋势。且由于不同集聚区内扩散效应在空间上渗透不均衡，其关联性主要表现为空间依赖性和空间异质性。③区域一体化背景下长江中游城市群ULUE在空间关联上具有“近水楼台先得月”和“门当户对”的特征，地理位置的空间相邻、投资消费结构和产业结构的相似是其空间关联的主要成因。     

基于供求关系的房价波动分析

基于1999—2017年中国35个大中城市的面板数据，构建基于供求关系的面板回归模型，从国家和区域两个层面对造成房价波动的原因进行探究。结果表明:价格预期在全国和区域模型中均对房价有显著的正向影响，且在大多数地区，其影响力大于其他因素；人口对房价有正向影响，但只在北部沿海、东部沿海和南部沿海显著；收入对南部沿海、黄河中游和西南地区的房价均有显著的正向影响，而在北部沿海、东部沿海、长江中游、西北地区和东北地区，该因素对房价的影响并不显著；除全国和西南、西北地区外，房屋造价作为成本因素对绝大多数地区的房价有正向影响；信贷的可获得性作为政策因素对房价有正向影响，除南部沿海和黄河中游外，在其他区域均显著；住宅开发投资与住宅价格呈负相关关系，但其只在少数经济发达地区显著。因此，未来对房地产市场的调控应根据区域房价波动影响因素的不同区别对待，因地制宜。

科技金融结合试点政策对地区经济增长影响研究——基于科技创新与产业结构合理化的视角

科技金融是"第一生产力"与"第一助推力"的有机结合,承担着带动地区经济高质量发展的重要使命.基于当前我国科技金融结合不断推进的背景,文章以2007—2016年我国共285个地级市的面板数据为例,运用双重差分法(DID)对科技部、中国人民银行等五部门推行的科技金融结合试点政策对试点地区经济增长的带动效应及机制进行检验.结果表明:第一,科技金融结合试点政策能够有效带动试点地区经济增长,这一结论具有稳健性;第二,科技金融结合试点政策对试点地区经济增长的带动作用存在显著的地域性差异,东部最强、中部次之、西部最弱;第三,进一步的机制检验表明科技金融结合试点政策能够通过提升地区科技创新水平和推动产业结构合理化的双重路径带动地区经济增长.为了进一步推动科技与金融相结合,提升地区经济发展水平,各地政府应高度重视科技金融结合试点政策对地区经济发展的正外部性,积极申报试点城市建设.同时,应结合各地市情社情制定差异化试点政策,大力提升科技创新与产业结构合理化水平,充分发挥其对地区经济增长的中介作用.     

集体行动、财政激励与村级公共产品自主供给

利用农村“一事一议”制度变迁作为研究对象，从影响农村居民集体行动的社会因素与财政因素两个维度，对农村公共产品自主供给进行实证分析，研究证实：“一事一议”制度有利于农村公共产品的结构优化，其显著提升了村级公共服务的供给绩效。农村传统的“宗族”社会结构有利于克服集体行动中的“自利行为”和“搭便车”倾向，促进了“一事一议”的开展，而当前逐步扩大的收入差距形成了公共产品的偏好差异，提高了“一事一议”的交易成本，但是有效率的村级治理体制对村庄开展“一事一议”具有促进作用。“一事一议”挂钩的财政补助，具有显著的“激励效应”。实证研究结论对于创新农村公共产品供给方式，培育内生性的公共产品自主供给机制，提供了决策依据。     

乡村振兴战略下中国农村金融立法的完善

乡村振兴战略是贯穿于中国决胜全面建成小康社会和全面建成社会主义现代化强国全局的系统性工程，完善农村金融相关法律有助于更好地满足乡村振兴多样化的金融需求。完善政策性金融立法应当以供给侧结构性改革为主线，明确农村政策性金融机构职能，深化政策性金融与财政支农的资金整合，促进服务实体经济；完善商业金融立法应当以服务"三农"为根本，法定农村商业金融机构的社会责任，对农村土地和资产上市作出法律回应，着力深化金融改革；完善合作金融立法应当以普惠金融为理念，盘活民间金融资源，对农村合作金融组织开展业务进行统一监管，重点防控金融风险。农村金融法律的完善应当注重整体统筹，促进立法取向的协调稳定，为金融支农、服务乡村振兴提供法治保障。     

Global adjustment to US disengagement from the world trading system

US trade policy in the Trump administration is protectionist, raising tariffs outside of WTO rules, threatening trade wars, withdrawing from existing trade agreements, and negotiating new bilateral trade deals rather than free trade agreements. The reaction of the rest of the world has been to support the WTO rules-based trading system and to pursue new and expanded regional trade agreements that do not include the US. The result may be US disengagement from the world trading system, with countries diverting trade around the US. We use a global computable general equilibrium (CGE) model to analyze changes in trade and production patterns for a variety of scenarios, including US trade wars. We find that adjustment to US disengagement is feasible—the changes in trade shares as countries divert trade are modest and achievable, with very little impact on the volume of global trade. If the US engages in trade wars with major partners, the best response for other trade partners is to sit out the trade war, accept higher US tariffs, and gain markets from global trade diversion around the US. Finally, because of indirect effects, widespread tariffs fail to benefit the protected sectors—a fallacy of composition in a protectionist trade policy.     

Cognitive abilities,self-efficacy,and financial behavior

This paper investigates the effect of cognitive abilities on financial behavior among older adults. Using the U.S. Health and Retirement Study, I find that cognitive abilities significantly affect financial behavior through two channels: ability and self-efficacy. People with higher cognition scores achieve better financial outcomes. This positive association is especially strong in tasks having high demand of cognitive abilities, which confirms the ability channel of the cognitive ability effect. In addition, there is evidence for the self-efficacy channel as a secondary source of cognitive influence. Lower cognitive abilities decrease people’s sense of self-efficacy, which, in turn, significantly decreases financial management efficiency. The findings have important policy implications, specifically that more effort is needed to assist the growing older population through the cognitive aging process and that noncognitive skills, as a secondary source of influence, also warrant attention.
