我国存款保险制度“显性化”研究

存款保险制度具有稳定金融体系、保护存款人利益、降低金融风险等功能。通过对隐性存款保险制度与显性存款保险制度的比较,和对我国建立存款保险制度的障碍的分析显示,建立显性的存款保险制度是我国金融体制改革的必然要求。

为将六安市规划打造成为全国陆路型物流节点城市,发挥六安市区位及交通优势,推动地区产业升级、优化城市发展格局。基于六安地区铁路总图规划,结合城市经济、产业布局、交通条件、用地条件等,确定新建铁路物流基地选址。根据选址车站枣树店站的地理位置、铁路条件和功能分区设计,提出平行铁路布置方案与垂直铁路布置方案2个方案。经综合比选,推荐采用作业效率高、工程代价小的平行铁路布置方案,加快实现六安市物流产业网络化、集约化和信息化,促进区域产业升级转型。     

Precarious postdocs: A comparative study on recruitment and selection of early-career researchers

This paper investigates how the recruitment and selection for project-based postdoc positions are organised in the current academic landscape characterised by increasing temporary research funding and how principal investigators construct the ‘ideal’ postdoc. Our findings are based on a qualitative comparative multiple-case study in Social and Natural Sciences departments of universities in four European countries. This study contributes to the literature on the neoliberal university and academic staff evaluation by using a systemic, power-sensitive approach that examines how postdocs enter the academic system and how manifestations of precarity are exacerbated. Our critical analysis reveals three manifestations of precarity that the current academic system creates for postdocs, related to control, contracts, and careers. We discuss the effects for individual postdocs and their careers and the quality of knowledge production in public funded higher education institutions.     

灵活就业人员医疗保险参与及受益归属——基于逆向选择和正向分配效应的双重检验

当前,灵活就业人员医疗保险发展不充分与不平衡的问题格外突出,这不仅会制约医保制度公平性与可持续能力的提高,同时会阻碍经济社会的全面、协调和可持续发展。本文运用中国劳动力动态调查数据(CLDS),研究灵活就业人员参加医保的决定因素以及受益归属,从而为新时期医保制度顶层设计提供决策依据。结果表明:一方面,无论是在参保决策还是险种决策阶段,灵活就业人员的健康风险显著正向影响参保状态,说明逆向选择效应显著存在;另一方面,低收入的参保人利用了更多优质的医疗服务,获得了更多的医保基金补偿,并显著改善了健康状况,因此医保发挥了积极的正向分配作用。但是过高的保障水平,在改善医疗可及性的同时会激发道德风险,从而加剧逆向选择问题并阻碍正向分配效应,对更加公平可持续医保制度的建立造成负面影响。     

The perils of working with big data,and a SMALL checklist you can use to recognize them

The use of big data to help explain fluctuations in the broader economy and key business performance indicators is now so commonplace that in some instances it has even begun to rival more traditional measures. Big data sources can very often provide advantages when compared with these more traditional data sources, but with these advantages also come potential pitfalls. We lay out a checklist called SMALL that we have developed in order to help interested parties as they navigate the big data minefield. Based on a set of five questions, the SMALL checklist should help users of big data draw justifiable conclusions and avoid making mistakes in matters of interpretation. To demonstrate, we provide several case studies that demonstrate the subtle nuances of several of these new big data sets and show how the problems they face often closely relate to age-old concerns that more traditional data sources are also forced to tackle.     

City goes dark: Dark trading and adverse selection in aggregate markets

We investigate the impact of dark trading on adverse selection in an aggregate market for trading UK stocks. Dark trading is linked to lower adverse selection risk and improved informational efficiency and liquidity in the aggregate market, even as liquidity declines in the lit market with dark trading. However, there is a trading value-based threshold when dark trading starts to induce adverse selection. We estimate that this threshold varies from around 9% for the most liquid stocks to 25% for the least liquid stocks. The overall average threshold for the 288 FTSE 350 stocks in our sample is 14%.     

信息不对称、信号传递方式与供应商甄选博弈

论文从供应商传递信息方式的角度来研究信息不对称情形下供应商的甄选问题。研究首先将对称信息与非对称信息情况下供应商甄选结果及供需双方的收益进行比较．得出信息不对称导致供应链上供应商的逆向选择问题。然后运用信号传递成本无差异与信号传递成本有差异这两种类型信号博弈模型来解决不对称信息下的供应商选择问题，并得出结论只有信号传递成本在不同类型的供应商之间存在差异，信号才能起到类型显示的作用，从而解决信息不对称情形下供应商的甄选问题。     

套息交易对中国短期资本流动的影响——基于动态资产组合理论的研究

本文基于动态资产组合最优权重的变化研究套息交易对中国短期跨境资本流动的影响。通过将人民币套息资产、美元无风险资产和美元风险资产作为基础资产,构建国际投资组合,计算动态最优权重并考察其对中国短期资本流动的影响。结果显示,当汇率及利差等状态变量随时间发生改变时,套息交易资产组合的最优权重也会随之发生改变,且能显著地解释我国短期资本流动的变化,但套息交易的资产配置并不是导致当前我国资本流动出现趋势性变化的根本原因。     

技术选择：“因势利导”还是“适度赶超”？

研究目标：面对“因势利导”与“适度赶超”两种看似相悖的技术选择战略,发展中经济体应该如何抉择。研究方法：利用1990~2014年的中国省级宏观数据与典型行业数据,通过多种实证工具分析了不同人力资本条件下技术选择战略对全要素生产率的影响。研究发现：20世纪90年代以来,赶超式的技术选择战略总体上抑制了中国全要素生产率的增长。而人力资本则构筑了适宜采用“因势利导”还是“适度赶超”战略的分水岭。在人力资本积累不足的情况下,技术选择必须严格遵循要素禀赋的演进趋势;而在人力资本积累充分的情况下,适度偏离要素禀赋的技术战略将是更具效率的政策选择。研究创新：以人力资本为线索为两种技术选择战略搭建了一条能够相互实现逻辑自洽的理论框架。研究价值：为中国各地区选择适宜的技术进步路径提供了参考依据。
