Network structure,portfolio diversification and systemic risk

We investigate the effect of portfolio diversification on banking systemic risk, where the network effect is incorporated. We analyze three kinds of interbank networks, namely, random networks, small-world networks and scale-free networks. We show that the effect of portfolio diversification on banking systemic risk depends on interbank network structures and shock types. First, systemic risk increases first and then reduces with the increase of the level of portfolio diversification in the case of the individual shock. Second, in the case of the systemic shock, systemic risk reduces with the increases of the level of portfolio diversification. Third, banking systems with scale-free network structures are the most stable, and those with small-world network structures are the most vulnerable.

Form, function, and finance: architecture and finance theory

At least at first glance, a bank’s customers ought to be concerned with only one thing—the price they must pay for the services they receive. Architecture beyond the merely functional ought to have no role, especially not in the modern global economy in which increasingly automated financial intermediation of all sorts appears to be approaching the ideals of pure competition and perfect efficiency. Even in these financially sophisticated times, however, symbols matter, and the message communicated by these symbols is one which cannot be communicated in any other way. It is necessary for a financial institution, and perhaps even the financial system itself, to have a strong visual presence. There is a visceral appeal of an architecturally distinguished building to the senses that speaks to us in a way that the cerebral appeal of pure information cannot.     

电子商务环境下的内部控制与风险管理

会计职业人员对评估内部控制并实施风险管理的技能已熟知多年。这种经过时间检验并证明行之有效的经验和专业技能是会计职业产业独特影响的知识基础。随着电子商业的发展，尽管目前尚没有统一且标准的定义，但其发展对会计职业却提出了挑战。从某种意义上讲，企业的风险评估增加了很多新的内容，而与之相对应的内部控制也需要进行必要的调整，从而实行风险管理。本文拟就电子商务环境下的内容控制和风险 管理及其手段进行分析。

MEASURING THE OPERATIONAL EFFICIENCY OF COMMERCIAL BANKS IN NAMIBIA

This paper examines the efficiency of commercial banks in Namibia using the standard econometric frontier approach. Although two aspects of efficiency (scale and scope) receive our attention, the emphasis is on the latter which pertains to whether a firm produces as efficiently as it possibly can, given its size. Our results indicate that substantial economies of scale exist in commercial banking in Namibia. This will tend to suggest that commercial banks in Namibia can increase their efficiency by increasing their current scale of operation. The results for scope economies show that the current level of input combination does not make for maximum efficiency as sufficient scope exists for a more efficient combination of inputs. We believe this will reduce operating costs in the industry and stimulate efficiency.     

The market’s view on the probability of banking sector failure: cross-country comparisons

Hall and Miles (1990) suggest an approach of estimating default probabilities of banks using stock market information, and in this paper we apply an aggregated version of their approach to banking sectors around the world in both developed and emerging economies. We study the market’s assessment of the probability of systemic banking crises world wide over the last decade, including the Asian crisis 1997–1998. In addition, we investigate whether there is a relationship between the failure probability and institutional features of the actual banking sector. The quality of governance and the degree of law and order in a country is found to be significantly negatively related to the market based failure probabilities as is an explicit deposit insurance during periods of crisis.     

数字时代的银行业变迁——网点布局与行业结构

数字技术可以帮助市场主体重构组织模式,数字经济时代的金融业也因此迎来变革。本文基于2014年至2019年我国县级行政区数据,研究发现,数字金融的发展显著减缓了我国银行业金融机构实体网点的扩张势头,这种效应主要体现在股份制商业银行和城市商业银行上,并主要影响这两类银行的基层机构。同时,我们发现数字金融的发展加快了农村合作金融机构的转型和网点退出,但对国有“六大行”没有显著影响。进一步研究发现,数字金融的影响效果会随着经济发展程度提高和地区金融可得性增加而增强,但随着在位银行的市场势力提升而下降。本文为理解数字经济时代银行业的变迁提供了一定参考。

信贷技术、银行业竞争与中小企业融资

不同的银行信贷技术对中小企业具有不同的影响,银行业的逐渐开放,竞争的日益激烈,银行间并购逐年增加,银行业竞争结构的变化严重影响着中小企业融资。随着中国经济与世界经济接轨程度的加大,《新巴塞尔协议》的逐步推行,将不同程度影响银行业竞争结构及中小企业的信贷供给。因此,在制定相关政策时,要充分考虑金融政策的传导机制,不仅考虑其对金融体系及金融中介竞争结构的影响,而且还要考虑到对中小企业融资的间接影响。
