Features selection,data mining and finacial risk classification: a comparative study

The aim of this paper is to compare several predictive models that combine features selection techniques with data mining classifiers in the context of credit risk assessment in terms of accuracy, sensitivity and specificity statistics. The t‐statistic, Battacharrayia statistic, the area between the receiver operating characteristic, Wilcoxon statistic, relative entropy, and genetic algorithms were used for the features selection task. The selected features are used to train the support vector machine (SVM) classifier, backpropagation neural network, radial basis function neural network, linear discriminant analysis and naive Bayes classifier. Results from three datasets using a 10‐fold cross‐validation technique showed that the SVM provides the best accuracy under all features selections techniques adopted in the study for all three datasets. Therefore, the SVM is an attractive classifier to be used in real applications for bankruptcy prediction in corporate finance and financial risk management in financial institutions. In addition, we found that our best results are superior to earlier studies on the same datasets.     

Optimal mixed taxation,credit constraints,and the timing of income tax reporting

We study optimal income and commodity tax policy with credit‐constrained low‐income households. Workers receive an even flow of income during the tax year, but report their incomes and make tax payments (receive transfers) at the end of the year. They spend their disposable income on multiple commodities over the year. We show that differentiated subsidies on commodities can be optimal even if the Atkinson–Stiglitz Theorem conditions apply. When the optimal policy leaves low‐income households with binding credit constraints, it may be optimal to subsidize differentially the good that they consume in higher proportion. Uniform subsidies would also relax the credit constraint, but would be more costly to the government since they would equally benefit unconstrained households. Numerical examples suggest that commodity tax differentiation increases with basic needs and with the interest rate at which government borrows.     

When Overlapping Organisations Play Two-Level Games: IMF–EU Interaction in Credit Lending to Latvia and Greece

In the literature, the cooperation of the IMF and the EU in credit lending has been discussed either from a state-centric, bureaucratic or institutionalist perspective. In this article, we examine the Troika as a set-up of multiple organisational overlap providing bureaucratic agents with constraints and opportunities for strategic action. Taking Latvia and Greece as cases in point, we analyse who prevails in a situation of conflict and why. How do these international organisations manage to overcome their differences and reach consensus? Drawing on the Two-Level game approach, we argue that negotiators are more likely to prevail over each other when their respective win-set decreases. We find that different strategies to manipulate win-sets are decisive to explain both cooperation and assertiveness. Changing costs of no agreement during a lending programme as well as the institutional procedures for programme ratification facilitate the use of these strategies.     

Fiscal policy,government debt,and economic growth in the Kaleckian model of growth and distribution

This article presents the Kaleckian model of growth and distribution that sets a budget deficit ratio as an indicator of fiscal policy and examines the short- and long-run effects of an increase in budget deficits and a rise in income tax rates on the economy. The key short-run outcomes are as follows. First, expanded budget deficits have a positive effect on the rate of capacity utilization. Second, the tax rate for wage income does not affect the rate of capacity utilization, whereas the tax rate for capital income has a favorable impact on it. This result implies that raising the tax rate for capital income can be an important policy instrument for stimulating the economy. Third, we find that the economy exhibits a wage-led aggregate demand in the short run. The main long-run results are as follows. First, the effect of expanded budget deficits on the growth rate is ambiguous, since a higher debt burden negatively influences the rate of capacity utilization and hence economic growth, despite the increase in demand caused by government borrowing. A higher budget deficit ratio thus raises the growth rate only if a certain condition is satisfied. Second, the tax rate for capital income has a positive impact on the growth rate. Third, the economy shows a wage-led growth in the long run.     

The evolution of State-Local balance sheets in the United States, 1953–2013

State and local debt in the United States more than doubled as a share of gross domestic product between 1953 and 2007. Using a historical accounting framework, we find that there is no straightforward relationship over time between state and local deficits and debt growth. We find that only 17 percent of the variation in aggregate state–local debt ratios comes from variation in the fiscal balance. This is especially true in the 1980s, the period of most rapid increase in state–local debt ratios. Before 1980, there were small but persistent deficits, but stable debt ratios. In the 1980s, state and local sectors shifted toward budget surpluses but saw rising debt ratios. This is explained by a faster pace of asset accumulation. Our results demonstrate the autonomy of balance sheet variables and suggest that changing debt ratios cannot be explained by real income and expenditure flows.     

信贷政策、银企关联与企业资本结构

本文从供给政策和银企关联两个层面出发,揭示信贷政策、银企关联对资本结构影响的理论机制,并提出3个理论假设,并以2003-2012年间360家上市公司为样本分别进行实证检验。结果表明,信贷供给和银企关联对资本结构具有显著的正向影响效应,并且两者之间存在显著的替代关系。鉴于此,必须加快发展和完善多层次资本市场,拓宽企业融资渠道,降低企业的融资成本;重视银企关联这一非正式制度安排对企业资本结构的作用,预防甚至减少违规现象的出现。     

社会信任与会计盈余的债务契约有用性

社会信任是一种重要的非正式制度,其如何影响企业微观机制值得探究。以2000-2014年中国A股制造业上市公司为样本进行研究,发现社会信任有“连坐制”效应,社会信任越低的地区,会计盈余的债务契约有用性越显著;相比国有企业,非国有企业中社会信任对会计盈余债务契约有用性的影响更显著。在使用Heckman二阶段模型纠正样本选择偏误后,上述结论依然成立。研究结果对于充分认识社会信任的重要作用以及发挥会计信息的治理功能,具有重要意义。     

中国评级市场被“劣币驱逐良币”机制主导了吗

声誉机制能够产生“优胜劣汰”的压力,是对评级机构行为的重要约束。中国舍本逐末的评级制度安排和不成熟的市场环境不仅阻碍了声誉机制的形成,还为评级机构出具过高评级提供了空间。根据该情况构建的评级合谋市场均衡模型,证明了我国评级市场竞争增加会导致评级质量的下降。利用鹏元资信评估有限公司进入城投企业债评级市场作为自然实验的进一步研究对理论进行了验证。分析表明,“劣币驱逐良币”的恶性竞争机制在我国评级市场占据主导地位。为此,我国在长期内应当对评级行业的制度安排进行重新设计,建立以声誉机制为主导的市场环境;短期内则需要加强监管,同时控制评级市场的竞争程度。     

信贷资金融资服务效率与融资服务功能--基于中小企业的问卷调查

以6地区339家企业的问卷调查数据为基础对政策性银行贷款、商业性银行贷款、民间信贷三种资金为中小企业融资服务的效率进行实证考察,结果显示：三种资金对中小企业发展起正向促进作用,政策性资金和民间信贷资金融资服务效率高于商业性银行资金;三种资金投向具有规模企业偏好,与扶持小微企业发展的实践相矛盾;三种信贷资金行业服务效率差异明显,政策性资金对高新技术类企业融资服务效率高;民间信贷资金融资服务对象定位不明确,影响了其为中小企业服务的综合效率,亟需政策的规范和引导;在中小企业融资服务体系中三种资金具有联动效应。这些结论为合理界定三种信贷资金在中小企业融资服务体系中的服务功能和服务区间提供了依据。
