Liquidity risk and policy options

On the basis of a liquidity management model, liquidity risks, defined as the probability of payment failures in a real-time gross settlement (RTGS) payment system, may either stem from liquidity management inefficiencies or insufficient cash balances. I will show that penalties charged on the amount of payment failures minimise liquidity risks without interfering with the bank’s technology preferences. I will instead show that liquidity requirements, although as effective as penalties to contain the risk of liquidity shortage, may distort the bank’s technology preferences and cannot stem liquidity management inefficiencies. I will also show that liquidity risks within RTGS payment systems are potentially smaller because they depend more on the liquidity management efficiency than on the randomness of cash inflows and outflows.     

Solvency Ⅱ与C-ROSS非寿险保险风险最低资本要求比较研究——基于中国60家财产保险公司的经验证据

本文以非寿险业务保险风险最低资本要求为考察对象,研究了欧盟Solvency Ⅱ与中国C-ROSS的差异,并利用中国保险市场60家财险公司的经验数据,对两者之间的差异进行了实证和模拟分析。研究结果表明,Solvency Ⅱ和C-ROSS对中国财险公司保险风险最低资本要求存在差异。对于拥有传统业务结构的财险公司,Solvency Ⅱ对保险风险最低资本要求更高,但是这种差距随着公司业务规模的缩小而减弱;对于以经营某些专业险种为主的财险公司,主营业务险种对两者差异具有决定性影响。本文的研究结论详细解释了Solvency Ⅱ与C-ROSS在非寿险保险风险最低资本计算上的异同,对C-ROSS下一步的修订工作提供了一定的支持与参考。     

An integrated system for information security management with the unified framework

Information security management plays an essential role for drawing the roadmap of information security; thus, many theoretical methodologies and practical standards are brought into this domain. However, many standards and methodologies are too cumbersome to be adopted by an organization. Additionally, there is no unified framework to systematically handle the tedious tasks of information security management. This study’s primary goal is to design an integrated system for information security management (ISISM) that aims to use current methodologies and standards to solve the above-mentioned issues. Because business impact analysis and risk analysis are the most important areas within this domain, we carefully select the related methods and then integrate them into a unified framework, upon which the proposed ISISM depends. To achieve this outcome for this study, security requirement engineering is adopted, which enables the designed system to support system users in generating risk assessment reports with related information security policies.     

Trust or not: Heuristics for making trust-based choices in HR management

The present two studies examine how the participants (i.e., 150 managers) make trust-based employee selection in hypothetical situations, based on five cues of trustworthiness derived from previous surveys. In Study 1, each executive participant is presented with a pair of candidates with different cue profiles so that the choice would favor one of them based upon each of the four following heuristics: Franklin's rule, likelihood expectancy, take-the-best (TTB), and minimum requirement (MR). Study 2 adopting a within-subject design jointly compares the four heuristics. The results show that simple heuristics (MR and TTB) outperform the more complex strategies (Franklin's rule and likelihood expectancy) in their predictive accuracy. The MR heuristic, a heuristic tallying the frequency of passes against a set of minimal rather than optimal or satisfactory requirements, performs even better than the TTB heuristic, particularly when the number of the cues identified as MRs is small.     

CPA credential perceptions: a case study of Hispanic accountants

One of the recommendations of The Pathways Commission report was to increase the number of diverse entrants into the accounting profession. While the Commission’s recommendation is commendable, the lack of diversity in the accounting profession is not a new problem. Hence, the accounting profession has attempted to address the underrepresentation of minority Certified Public Accountants (CPAs) for many years. To this end, organizations such as American Institute of CPAs (AICPA), National Association of Black Accountants (NABA), Association of Latino Professionals in Finance and Accounting (ALPFA), and the Ph.D. Project have provided different types of support to alleviate the problem. However, the numbers are still disturbingly low. This is particularly true for Hispanic accountants. Therefore, the purpose of this study was to examine Hispanic accountants’ perception of the CPA credential. While the results indicate that gender, exam affordability, and job incentives are positively associated with the likelihood of being a CPA, the 150-hour requirement was not perceived as a hindrance for certification.     

Stochastic costly state verification and dynamic contracts

I consider a dynamic costly state verification environment in which a risk-averse agent enters into a contract with a risk-neutral principal. The agent has random income which is unknown to the principal but can be verified at a cost. The principal can commit to executing random verifications.I extend the standard recursive methods to study the problem and show that it is optimal to set verification probabilities strictly less than 1. If the agent׳s absolute risk aversion declines sufficiently slowly, the principal will use verification regardless of its cost. If the agent's income is verified then he would get consumption and continuation utility strictly higher than if his income were not verified.     

CMMI指导下信息系统需求变更度量框架的构建与应用

需求变更的管理不善往往会导致信息系统开发项目的失控。如何对需求变更加以有效的管理,便成为信息系统开发中一个迫切需要解决的问题。度量是管理的基础,可以将度量的方法引入需求变更管理中。CMMI指导下的信息系统需求变更度量框架的构建有助于变更管理的规范化,但该框架对应用的条件是有要求的。
