商业银行反欺诈后续处置的难点及对策

商业银行欺诈后续处置是指银行针对外部欺诈所采取的事件分析与追踪、风险防控与化解等系列处理措施，是反欺诈工作不可或缺的重要组成部分，更是从面上打击、震慑欺诈犯罪的有效手段。因此，各级管理者都应重视并持续强化此项工作。本文简要分析当前商业银行反欺诈后续处置的现状，针对存在的主要难点，提出相应的对策与建议。     

保险欺诈防范方法之二：内部数据查询

内部数据查询是保险公司防范欺诈的一种常用的方法，主要是依托公司的业务查询系统进行数据配对查询，以识别和发现保险欺诈。具有反欺诈功能的公司业务查询系统可以设计成公司综合业务处理系统的一部分或者单独设立，但不管怎样该查询系统的正常运转需要公司综合义务处理系统的支持。这种支持主要的数据方面的，要保证可能与欺诈有关的各类业务信息能够及时地（最好是同步地）向业务查询系统集中，只有满足这样的技术要求，业务查询系统才能真正发挥识别和发现保险欺诈的作用。     

商业银行欺诈信贷问题及内部审计策略

欺诈信贷问题是指借款人通过提供虚假的财务信息在商业银行骗取贷款资金的行为,按风险程度可以区分为一般性、严重性欺诈和恶意骗贷式欺诈。欺诈信贷在商业银行内部流程上表现为贷款调查多从管理决策审批层次发起或授意发起、贷款审议经历复议和相关职能部门及岗位未尽职等特点,在欺诈者自身表现为财务信息虚假、规避监管,多地、多行开户,关联交易、虚假支付,以及贷款申请用途与实际用途不符等特点。欺诈信贷的本质是财务欺诈,具有传染性特征,对商业银行信贷资产安全构成较大威胁,加强对欺诈信贷的审计策略研究意义重大。     

基于医保欺诈检测的RF与XGB模型比较

随着我国综合国力的增强,国家在医疗保险上的投入不断加大,但与此同时,医保欺诈行为也不断发生.本文采用深圳市某家医院一个月的医保数据记录,在对原始数据进行预处理后,分别建立RF模型和XGB模型对医保正常数据和欺诈数据进行分类预测,最后,利用评价指标F1值和AUC值对两模型的分类预测结果进行比较,得到更适合医保欺诈检测识别的模型.     

信用卡欺诈风险透析与防范机制

近年来，国内信用卡业务蓬勃发展，发卡量激增。在高速发展的同时，信用卡业务的风险也日益显现，信用卡欺诈案件呈不断攀升的趋势。如何在业务快速发展的同时控制风险，防止因信用卡欺诈而给持卡人、商业银行和整个社会带来危害，是发卡银行面临的一个十分严峻的问题。商业银行迫切需要建立起有效的信用卡欺诈风险防范机制。     

以本土化原则开发商业银行内部评级系统

作为《新资本协议》核心的内部评级法将成为银行风险管理和资本监管的主流模式。所以，我国银行业为适应《新资本协议》的监管要求，应尽快建立与之相一致的内部评级系统。目前，监管部门和各家银行特别是大银行已开始着手相关方面的研究并进行着前期的准备工作。坚持本土化的原则，开发商业银行的内部评级系统，具体包括：夯实数据基础；研究、开发本土化的内部评级模型；加强内部评级系统的测试、优化、升级和维护；优化贷款业务流程；实现与其他系统的对接与嵌入。     

商业银行操作风险管理的国际比较研究

建立和完善操作风险管理体系已经成为现代商业银行急需解决的重大课题.本文通过商业银行操作风险管理的国际比较分析并加以总结,在此基础之上对我国商业银行操作风险的现状和特征进行了分析,指出我国商业银行操作风险主要集中在内部欺诈特别是管理层欺诈.我国商业银行管理层内部欺诈产生的主要原因是银行特别是国有商业银行公司治理结构不够完善、"内部人控制"问题和对管理层监督与激励不足.所以,我国商业银行业应从实际出发,认真借鉴国外先进经验,从体制和机制改革入手积极防范和控制操作风险.     

基于对抗学习的信用卡欺诈检测动态模型探索

信用卡欺诈对许多金融机构来说是一个棘手的问题,尽管金融机构基于机器学习算法构建了各种欺诈检测系统,部分欺诈者仍然可以避开欺诈检测,因为这些系统通常不包含有关对手了解欺诈检测机制的信息。为了将欺诈者不断扩充的知识库信息纳入自适应欺诈检测系统,本文基于信用卡欺诈检测动态模型研究项目(以下简称“项目”),探索使用博弈论对抗学习方法来模拟欺诈者的最佳策略,并先发制人地调整欺诈检测系统,提升其应对潜在威胁的能力。     

论商业银行内部评级系统的建立

笔者在考察巴塞尔新协议内部评级法和十国集团商业银行的内部评级系统的基础上，分析了我国商业银行内部评级系统建设的现状和构建符合色塞尔新资本协议并且适合我国商业银行情况的内部评级系统的对策，并讨论了如何在中国建立良好的信用风险管理机制。     

数据模型在信用卡欺诈风险防控中的应用探索

近年来,信用卡交易线上化进程加速,在便利持卡人生活消费、提高金融服务体验的同时,也给信用卡欺诈风险防控带来新的挑战。一方面,交易线上化降低了犯罪分子的欺诈成本,提升了交易复杂程度,催生出新型网络欺诈手段,使得电信网络诈骗交易的链路更长、网络更广、速度更快,进一步压缩了商业银行更新防控策略和模型的时间。另一方面,《关于进一步促进信用卡业务规范健康发展的通知》的出台对商业银行管控信用卡套现、资金流向等提出了更高要求,并鼓励管控措施前移。总体而言,各类欺诈交易与正常交易界限逐渐模糊,风险隐蔽性、复杂性皆在提升,商业银行需要不断提高数字化反欺诈能力。     

Short-sale refinancing and price adjustment speed to bad news: Evidence from a quasi-natural experiment in China

Short selling may accelerate stock price adjustment to negative news. However, the literature provides mixed evidence for this prediction. Using short-sale refinancing and a staggered difference-in-differences (DID) model, this paper explores the effect of short selling on stock price adjustment. Our results show that (1) short-sale refinancing improves the speed of stock price adjustment to negative news. This result holds after we control for endogeneity. (2) The positive relationship between short-sale refinancing and stock price adjustment speed is significant in subsamples of stocks with higher earnings management or lower accuracy of analyst forecasts, indicating that firms with more opaque information are more likely to be targeted by short sellers. In subsamples of stocks with a higher ownership concentration or lower ownership by institutional investors, short selling is more likely to increase the speed of stock price adjustment, indicating that ownership structure may influence negative news mining. (3) As short-sale refinancing exacerbates the absorption of bad news by stock prices, it increases crash risk. This study enriches the research on the economic consequences of short selling and provides empirical evidence supporting regulations on short selling in China.

The case for management history

This article defines the case for treating management history as a discrete subject area, although one closely related to business, accounting, labour, and industrial history. It seeks to concentrate on the nature, process, and practice of management as an activity within the organization, and to argue that it is important that modern British managers understand the intellectual and cultural roots of their profession, since without these they will tend to be swayed by short-term management 'fads'. Within the broad topic there are several identifiable sub-areas for potential exploration, including the comparative historical development of management between different countries, management institutions, managerial careers and labour markets, management structures, management skills, and management thought and theory.     

The life and career of John Spence Ogilvy (1805-71), the first chartered accountant to emigrate to Australia

So far as the available evidence allows, this paper examines the life and career of John Spence Ogilvy, foundation member of the Society of Accountants in Edinburgh in 1854, who emigrated to Melbourne in 1856, but did not play a part in the development of an organized accounting profession in Australia. The paper also attempts to explain the gap of thirty-two years between the formation of the first accounting bodies in Edinburgh and Melbourne.

The Impact of IFRS Adoption on an Agribusiness Company's Financial Statements

This fictional case is based on a Canadian public company that produces greenhouse vegetables. Focusing on the differences between International Financial Reporting Standards (IFRS) and Canadian Accounting Standards for Private Enterprises (ASPE), this case provides students an opportunity to (1) apply IFRS in a real world setting; (2) prepare and reconcile financial statements under ASPE and IFRS; (3) analyze the impact of IFRS adoption on key financial ratios; and (4) detect and explain differences in financial statements under ASPE and IFRS through common size analysis.
