一种SAR与可见光图像压缩感知融合增强方法

针对机载多传感器成像战场态势感知的问题，提出了一种合成孔径雷达(Synthetic Aperture Radar，SAR)与可见光图像压缩感知融合增强方法。该方法首先对SAR与可见光图像分别进行压缩感知测量，得到压缩测量值，然后通过基于局部权值的融合方法实现对压缩测量值的融合，再利用有序度最优分割法提取SAR图像的强散射目标，最后对融合测量值重建得到初步融合图像，初步融合图像通过目标对比度增强得到最终融合图像。对多组图像进行了仿真分析，视觉及数值结果表明该方法能显著增强融合图像的目标对比度，提升了图像纹理清晰度，较大程度降低了图像融合过程中的数据计算量。     

Credit card cash‐out as informal financing: Evidence from China

Using a proprietary account‐level database from a commercial bank in China, we document that credit card holders can ease their credit constraints through the practice of cash‐out based on bogus transactions using credit cards. We find that such behaviour might be beneficial to both cardholders and banks. First, we find that a 1% increase in the cumulative number of credit card cash‐out transactions lowers the probability of default by 9.59%. Second, for private businesses, a 1% increase in the number of abnormal cash‐out transactions lowers overdue risk by 13.45%. Third, by lowering the overdue risk, the card‐issuing bank earns a larger profit. Our results are consistent with the notion that unconventional credit card cash‐out can mitigate the extent of capital misallocation in emerging markets.     

青海省社会信用体系建设现状与发展路径

党的十八届三中全会以来，青海省全面实施深化改革工作，地方社会信用体系建设步伐显著加快。但是，还需通过自上而下的统一部署和强有力的制度约束，来解决信用基础薄弱、共享平台缺失、建设合力不足和以点带面机制不健全等问题。提出建立“总体要求———任务分解———基础工作———专项示范———支撑体系”这样一种全面的制度安排，以此为深化青海省社会信用体系建设提供新的思路。     

不同利率对我国上市银行信用风险的影响

对我国16家上市银行进行的实证检验表明：3个月同业拆借利率与银行信用风险显著正相关，人民币5年期基准存款利率与银行信用风险的关系不确定，人民币1年期基准存款利率与银行信用风险显著正相关，贷款利息收入占贷款比例与银行信用风险显著负相关。     

以廉政勤政简政为指引全面提升政府公信水平

近年来,我国政府公信力建设取得了巨大的成就,但也存在政策之间的协调性和行政体制的结构矛盾十分突出、政府公共服务和信息公开不能满足民众要求等问题. 要全面提升政府公信水平,就要深化行政体制改革,建立政府信用水平评价体系,推进政府信息透明化,完善政府对自身债务的管理,积极引导网络舆情.     

Labor Unions and Forms of Corporate Liquidity

We examine how the presence of labor unions affects a firm's choice of corporate liquidity between bank lines of credit and corporate cash holdings. We find that firms in industries with higher unionization rates hold a higher fraction of corporate liquidity in the form of bank lines of credit. We divide the firms into sub‐groups and find that this positive relationship holds for firms that are not in a state with right‐to‐work legislation and for firms that are financially constrained. Our findings are consistent with the hypothesis that a firm chooses the forms of corporate liquidity to take advantage of the bargaining benefits associated with bank lines of credit.     

Disentangling types of liquidity and testing limits-to-arbitrage theories in the CDS–bond basis

We disentangle asset-specific, market, and funding liquidity in the CDS–bond basis outside and during the 2007–9 global financial crisis. Our findings stress the importance of separating different types of liquidity, since all three measures have independently negative impacts on the basis. Funding liquidity emerges as the economically most important liquidity metric. While asset-specific liquidity is cross-correlated in both the cash and derivative markets, funding and market liquidity only matter for the cash market. We exploit the decomposition of the basis to test predictions of limits-to-arbitrage theories. We find strong evidence in favor of margin-based asset pricing and flight-to-quality effects.     

Fiscal and monetary interdependence

Where classical economics integrates the quantity theory of money with the concept of Ricardian equivalence, the tendency of recent macroeconomic presentations is to focus either upon money and inflation or upon taxation and debt. That neglect of classical monetary–fiscal integration is surprising, given an initiative by the International Monetary Fund that set credit, money, and fiscal policy within a single structure. This article places those ‘credit counterparts of broad money’ in the context of the Great Depression and the recent global financial crisis. The upshot is a set of conclusions: that, to counter the prospect of deflation, quantitative easing is a weak policy response; that fiscal deficits are better; and that cuts in taxation are preferable to increased government spending.     

Was the expansion of housing credit in Japan good or bad?

This paper shows, using data from the Family Income and Expenditure Survey, that housing credit has become increasingly available over time in Japan, especially since 2000, and that this has made it easier for Japanese households to purchase housing and enabled them to do so at an earlier age. However, it also shows that the greater availability of housing credit has increased households’ housing loan repayment burden, which has resulted in their cutting back on their other consumption expenditures and created the potential for retirement insecurity. Another concern is that the increasing availability of housing credit has been accompanied by a pronounced shift from fixed-rate to variable-rate housing loans. This is cause for concern given the low level of financial literacy that prevails among the Japanese population and the likelihood that interest rates on variable-rate housing loans will be raised sooner or later as monetary policy is tightened.     

绿色信贷如何影响银行财务绩效——基于地区绿色发展异质性的视角

基于2007~2017年中国34家商业银行非平衡面板数据，实证检验了商业银行开展绿色信贷对其财务绩效的影响，并利用《中国绿色发展指数报告》提供的分省绿色发展指数，考察了绿色发展对绿色信贷与银行财务绩效关系的调节效应。结果表明：商业银行发放绿色信贷投放有助于改善其财务绩效，并且这种改善效应主要来自绿色信贷对银行生息资产收益率的提升作用；绿色发展水平能够增强银行投放绿色信贷的经济效益，并且这种增强效应主要与地方经济增长绿化度和地方政府对绿色发展的支持度有关。商业银行应积极开展绿色信贷业务；政府部门应加强和完善绿色信贷激励政策，以推动绿色金融与绿色经济协同发展。
