Performance of microfinance institutions in Europe—Does social capital matter?

This paper investigates performance drivers of microfinance suppliers in Europe. As such suppliers, in contrast to advanced microfinance suppliers in developing economies, typically focus on uncollateralized microcredit services to individuals at the margins of society and of labor markets, we draw on the theory of social capital and empirically investigate the role that social capital may play in the overall performance of European microfinance suppliers. We build a unique, unbalanced panel data set of 302 microfinance service providers in Europe covering the years 2008–2015, and measure their performance in terms of credit risk, financial and social performance, and efficiency. Pursuing an econometric approach, we test a series of hypotheses using various measures of conditions conducive to building social capital on both the institutional and the country level, such as the client base of a microfinance supplier and the level of cultural fractionalization in a society. Our findings confirm that a higher intensity of social capital is positively associated with all areas of the performance of microfinance suppliers in Europe. Our conclusions could help in the design and launch of microfinance institutions in those European countries in which microfinance markets are developed not at all or only to a very limited extent. Our paper thus contributes to the nascent literature on microfinance in developed economies by applying and extending the theoretical framework and empirical models on social capital and microfinance that were originally elaborated for developing economies.     

我国基础研究管理及科研合作模式的多层次对比研究

根据我国现行旨在发展基础研究的科技计划，提出自由探索型和需求攻关型两种基础研究管理模式。基于CNKI数据库中国家自然科学基金与国家重点基础研究发展计划（“973计划”）发文数据构建科研合作网络，从宏观网络整体、中观网络成分和微观基元模体3个尺度，总结我国基础研究的4种科研合作模式，并对比分析两种管理模式的优缺点。结果表明，需求攻关型管理模式具有更多平衡型和流线型科研合作模式，自由探索型具有更多单点型、流线型和核心型科研合作模式，两种管理模式均需要大幅提升科研合作广度与深度；需求攻关型可以补短板但应对未来不确定性的能力不足，自由探索型可以应对不确定性但无法快速修补短板，两者分别作为长短期方案结合使用才能解决我国基础研究的“卡脖子”问题。     

嘉兴中心镇建设区域布局问题研究

本课题利用嘉兴市统计局第二次农业普查的有关数据,采取定量和定性相结合的方法,并在借鉴其它有关经济社会发展评价方法、指标体系的基础上,结合实际,通过主成分分析(采用指数法进行无纲量化处理,加权计算综合指数),对全市53个镇的经济社会综合实力进行了评价(评价排序未经评估),进而根据评价结果对各个镇的辐射范围进行计算和聚类分析,从而对嘉兴市中心镇建设区域布局问题提出合理化建议。     

Identifying systemically important financial institutions in Turkey

This paper examines the systemic risk of financial firms in Turkey. Using Component Expected Shortfall, we provide estimates of systemic risk in Turkey using daily data from 2005 to 2018 and a comprehensive data set encompassing 54 financial firms. Empirical results show that the preponderance of systemic risk in the sample in Turkey is due to large commercial banks. Top ten systemically important financial institutions dominate systemic risk measures in Turkey and account for more than 90 % of total risk over the sample. Consequently, the risk in the Turkish financial system is concentrated in specific financial institutions and makes close monitoring of the top firms essential. Historical incidence of systemic risk in the sample shows elevated levels of systemic risk correspond to well-known external events. Finally, a bivariate VAR model shows that systemic risk is correlated with measures of global financial risks and has significant negative effects on the real economy particularly on industrial production. This is important from a financial stability point of view in that close monitoring of the systemic risk is important in maintaining a healthy financial system and a well- functioning market economy.

基于主成份回归的国际原油价格分析与预测

基于国际石油市场的复杂性,文章考虑了影响原油价格的多方面因素,采用主成份分析的方法,从影响油价的众多因素中提取出能够反映原始变量的足够多信息的几个主成份,然后利用主成份对油价进行回归建立油价预测模型。并且对WT(I西德克萨斯轻质)原油月度价格进行了实证分析,说明了此方法的可行性及有效性。     

特征价格指数的理论与实证研究——以计算机价格指数为例

探讨特征价格指数的定义、作用和理论框架,由此得出结论:特征价格指数是根据特征价格函数计算出来的个体质量指数的统称。随着科学技术的不断进步和异质商品数量的增加,编制不同商品的特征价格指数对于提高中国价格指数编制质量和完善价格指数的编制方法具有重要的现实意义。文章实证部分引用G regoryC.Chow在“计算机的技术变化和需求”一文中使用过的数据,用以说明两种不同的计算机特征价格指数编制方法。实证结果表明:无论是合并数据指数模型,还是横截面数据指数模型均能剔除计算机的特征对其价格的影响,准确反映价格的变动趋势。而传统的价格指数由于忽略了商品品质的改变,有可能高估计算机价格的上涨幅度。
