Deposit interest rates, asset risk and bank failure in Croatia

Financial deregulation, while beneficial in the long-term, seems to be linked to instability. Intense competition for deposits appears to be an ingredient in instability. We examine the aftermath of deregulation in Croatia, which included rapid growth of both deposits and deposit interest rates, followed by numerous bank failures.

Using panel regression techniques, we find evidence of “market-stealing” via high deposit interest rates. We connect high deposit interest rates to bank failure using logit models. High deposit interest rates were a reliable signal of risk-taking. When supervisory capabilities and powers are weak, deposit interest rate regulation may be worth considering.     

Aggregate liquidity shortages, idiosyncratic liquidity smoothing and banking regulation

This paper develops a model of banking fragility driven by aggregate liquidity shortages. Inefficiencies arise from a failure of the interbank market to smooth the available liquidity in such a shortage. We find that a standard lender of last resort policy is ineffective in restoring efficiency as it leads to offsetting changes in the banks’ supply of liquidity. In contrast, subsidizing the purchase of assets from troubled banks increases welfare by improving the banks’ liquidity holdings. The first best, however, is achieved by redistributing existing liquidity from healthy to troubled banks in a crisis.     

减轻银行业税负提高银行业资本充足率

随着加入WTO过渡期的结束,我国内资银行业普遍面临着与外资银行间开展激烈竞争,以及资本充足率不足两大问题。本文分析认为,我国银行业税负与国外银行业比较相对偏重,内资银行业税负与外资银行业相比也较重。因此,减轻税负,完善金融税制是提高我国银行业资本充足率、增强自身竞争力的当务之急。     

Born internationals: Market expansion and business operation mode strategies in the digital media field

This paper examines leading Swedish and Finnish Internet consultancies operating in the digital media service field. These are ‘born international’ firms that internationalise their business at an exceptionally rapid pace. The paper focuses on why and to what extent the market expansion and business operation mode strategies of these companies deviate from the traditional pattern depicted by the Scandinavian process school. The empirical data consisted of interviews with the founder and senior management and secondary data from company and public archives. The research findings show that in fact both the international new venture research and the Scandinavian internationalisation model appear to be valid. The former model was evidenced by the fact that the born internationals indeed deviated from the behaviour of the traditional firms. The latter was exemplified by the fact that the final internationalisation profile, after the withdrawals of firms from unsuccessful markets, was close to what the Scandinavian internationalisation model would call ‘rational’ expansion. Hence, if the investigation period is long enough to account for unsuccessful endeavours and withdrawals, we may then find empirical support for the traditional model as well. To be reliable, the investigation period should cover at least one economic slow down.     

EVA与银行业的价值创造

中国的银行业,近年来由于体制、不良资产等各方面的原因,造成了效率低下,并且从有关的EVA统计数据看出,中国的银行业不仅没有在创造价值甚至在毁灭价值。面对着WTO五年保护期的即将届满,以及外资银行的纷纷踏入,中国的银行业应该怎样来创造自身价值呢?本文从经济增加值(EVA)的计算公式出发,从五个环节指出了中国银行业怎样进行价值创造,并通过举例的方式进行形象的说明。     

银行危机宏观影响因素变迁的实证研究

本文选择了108个国家在1980-2009年的样本数据,采用随机系数Logit模型,研究了宏观因素冲击对于银行危机的影响作用。研究结果表明,各种宏观因素的影响程度在不同经济发展水平国家的银行危机中具有明显的差异;银行体系的资产质量和流动性风险暴露是银行危机产生的最主要原因;且随着金融自由化和国际化的发展,银行危机的发生原因也逐渐发生变化。因此,与时俱进地采取某些监管措施,例如限制银行贷款增速、监控银行跨境资本流动、控制外债规模等,有助于降低银行危机发生的概率。     

数字经济、城市创新与区域收敛

当前,数字经济蓬勃发展,数据已成为除劳动、土地和资本等传统生产要素之外的新要素,能否依托数字经济发展赋能城市创新？文章在对数字经济的概念和内涵进行基本界定后,借助微观大数据构造的"互联网+数字经济"指数,实证分析了2015-2018年中国283个地区数字经济发展对城市创新及创新差距的影响。研究结果显示,数字经济发展能够显著促进城市创新水平提升。其中,人力资本集聚效应和创业活力增强效应是数字经济赋能城市创新的两条重要路径。在替换被解释变量、消除样本选择偏差、选择分位数回归,以及创新性地采用各地级市市长过去修习的专业作为历史工具变量检验后,这一结论依然稳健成立。进一步空间杜宾效应分析表明,数字经济发展具有显著的空间溢出效应特征,不仅促进了本地区创新水平提升,而且对相邻地区的创新产出也产生了实质性影响,有利于缩小区域创新差距,实现区域创新收敛。此外,相较于实用新型专利和外观设计专利,数字经济发展对城市发明专利的影响更显著,说明数字经济发展推动的创新是真正意义上的质量创新而非策略创新。文章为评估数字经济发展的影响效果提供了理论依据和经验支撑,也为理性看待数字经济、防止出现数字鸿沟,实现区域创新均衡发展提供了有益启示。     

以银行经营转型促进经济均衡发展

近年来我国经济一直是在一种不均衡的状态下实现快速发展的。以间接融资为主的融资方式，对银行本身乃至整个经济的可持续发展构成潜在威胁。为此，通过银行经营转型，优化储蓄向投资的转化路径，推动储蓄向消费的积极转化，是实现经济均衡发展的重要举措，同时也是银行体系本身可持续发展的需要。
