Structuring an effective human error intervention strategy selection model for commercial aviation

Flight safety cannot be compromised. Thus, commercial airlines should constantly develop safety management strategies to mitigate the diverse hazardous factors in flight operations. Given the constraint of organizational resource, a commercial airline may not have sufficient resources to implement all the necessary strategies simultaneously. This study uses a well-structured process to develop a qualitative evaluation model that will enable airlines to identify human errors and select an intervention strategy with the highest success potential. To clarify the decision problem, the Human Factors Intervention Matrix framework is utilized to construct the decision hierarchy. The Analytic Hierarchy Process is then used to attain the priorities of potential alternative strategies for various unsafe acts. Finally, Zero-One Goal Programming models are formulated to select an optimal portfolio based on the specific target and the available organizational resources. An empirical study is presented to illustrate the application of the proposed model. According to the results of the combined model, an optimal portfolio, including the intervention approaches of organizational/administrative, human/crew, and operational/physical environment, can remediate four unsafe acts, namely, decision errors, skill-based errors, perceptual errors, and violations, under resource constraints of the organization.     

我国商业银行效率测度分析——基于SFA技术的实证研究

基于2005~2012年22家商业银行的非平衡面板数据,运用超越对数生产函数形式的SFA技术实证分析了所选银行的经济效率值,选取的银行包括国有大型商业银行、地区性商业银行、农村和外资商业银行等类型。为考察所有制对银行效率的影响,以税前利润收入和贷款净额分别作为产出指标建立模型。并对低效率残差项的不同分布假设的精度进行比较,选出最优模型。研究表明:近年来我国商业银行效率整体水平有较大幅度提高;所选银行中,外资银行效率水平最高,地区性商业银行效率值最分散,国有商业银行的效率较集中,普遍位于0.8左右,农村商业银行的效率最低。最后,针对不同所有制银行的特点,提出提高其效率的政策建议。     

货币政策透明性制度的国际比较:以央行沟通方式为基调

自20世纪90年代末期以来,世界绝大多数央行的货币政策透明性有了显著提高,但是未表现出一致性收敛特征。各国央行的货币政策信息沟通面临着不同程度的现实约束,有的央行在某些方面透明性还非常有限。在央行信息沟通方面还有许多值得研究的策略性、细节性技巧,处理不当就可能损害央行信誉。我国货币政策透明度还处于较低水平,需要进一步提高。     

The Internationalization of Spanish- and Portuguese-Speaking Banks

This article investigates which variables affect the location choice of banks from Spanish- and Portuguese-speaking countries in their process of internationalization. The article compares the differences in these variables for public and private banks. The sample consists of 141 banks operating in 58 countries. Results show that internationalization is undertaken by the largest banks, which preferably choose countries with similar language, close to the home country, and with the most opportunity for growth. Additionally, the effects of certain explanatory variables on the probability of expanding to a given country are different for public and private banks.

Measuring market distortion: international comparisons,policy and competitiveness

This paper develops a framework to simultaneously estimate production possibility frontiers and measure distortions in factor and product markets. The econometric results, based on a panel of 61 countries over the period 1970 through 1985, reveal very little distortion in factor markets but considerable distortion in product markets. In addition, the distortions tend to vary with the cyclical behaviour of economic activity. Further, the results suggest that in order to improve efficiency, commercial policy should aim at reducing product-market distortions rather than factor-market ones.

Does financial regulation affect the profit efficiency and risk of banks? Evidence from China's commercial banks

The goal of financial regulation is to enable banks to improve liquidity and solvency. Stricter regulation may be good for bank stability, but not for bank efficiency. This research aims to examine whether banks have met the CBRC's standard of financial regulations and explores how the previously implemented financial regulations have affected bank efficiency and risk in the past. In addition, we also explored the trade-off relationship between efficiency and risk. Unlike other studies, this study used bank assets as a classification standard from the financial risk and differential regulatory perspective.The empirical results indicate that the CBRC regulates the provision coverage ratio and cost-to-income ratio, which seems relevant to large banks and the loan-to-deposit ratio, capital adequacy ratio, and leverage ratio, which seems relevant to small banks. The CBRC regulates the current ratio to reduce the risks of banks. Based on our empirical results, the current ratio did not affect the risks and led to different efficiency results between large and small banks. In an environment with asymmetric information, a bank decision-making is unobservable. The characteristics of financial regulation provide market clues if a bank is operating at the most efficiency and risk condition.
