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. 相似文献

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. 相似文献

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。 相似文献

当银行面对房地产价格冲击试图保持一定的资本充足率时,较轻的冲击就可能导致银行不稳定成为一种自我实现的结果,而当银行不维持最低资本充足率时,较为严重的房地产价格下跌才有可能导致银行的不稳定,可见,高资本充足率在一定程度上反而增加了银行体系的不稳定性。在特殊情况下,适当降低银行的资本充足率或补充资本、降低法定存款准备金率等增加银行体系流动性的政策可能是有益的。 相似文献

This fictional prototype explores two of the future's major societal challenges: the delivery of healthcare to an increasingly ageing society; and the policing of a society, in which digital surveillance may predominate. It contrasts the author's vision of what life could be like in the United Kingdom in a decade's time (just as he contemplates retirement) with the simpler values of the 1980s, when he began his postgraduate career. The lyrics of the poignant 1982 Bruce Springsteen song, “Highway Patrolman” are used to bridge the epochs1. The prototype relocates the two main ‘middle-America’ characters, brothers Joe and Frank Roberts, in London in the year 2025. Much has already changed politically and socially in ‘Western societies’ in the intervening period up to 2012, driven by the inexorable advances of technology. As further scientific advances drive us to an anticipated paradigm change,2 one can only speculate on how society will advance, posing serious ethical dilemmas. Many of the changes will be positive. However, the story explores the potential negative consequences to the ageing population, in what appears to be a successful economy. Although somewhat pessimistic in outlook, a hopeful conclusion is that the ‘ties that bind’ will still predominate. 相似文献

日本商业银行进入债券承销市场乃至日本金融业混业经营改革采取的都是一种渐进的方式,而包括金融业混业经营在内的日本金融改革对我国来讲具有较好的借鉴意义。从债券承销佣金、承销商选择和债券收益率价差等3个方面来看,日本商业银行进入债券承销市场是成功的,促进了债券承销市场的竞争,降低了企业发行债券的成本,提高了整体金融效率。就我国的具体情况来看,应在借鉴日本混业经营经验的基础上加快金融业混业经营的步伐。 相似文献

In the aftermath of the 2008 financial crisis, the entire Indian banking industry was paralysed and their performance was shattered by the unfolding of enormous cases of Non-performing Assets (NPA). The study estimates the operating efficiency of 40 Indian banks for 5 years (2011–15) as a proxy of performance measure using the output-oriented DEA-BCC model. We find that nearly 62% of the state-owned banks and 47% of the private banks are inefficient indicating that the inefficient banks need to reduce their inputs or improve their output to become efficient. The study further investigates the relationship between intellectual capital (IC) and bank performance using a truncated regression model. The regression results show that out of the three components of intellectual capital, only human capital efficiency is positively and significantly associated with operational efficiency while structural capital and finance capital have a negative impact on the efficiency of banks. The study concludes that to achieve competitive edge banks should invest in their human capital. The results are robust in the case of financial variables taken as a proxy for performance. 相似文献

本文提出了一种简单而实用的利用短时DFT(ST-DFT)分析实现全数字2DPSK接收机的解调算法。该算法对由多谱勒效应引起的时变频率漂移具有鲁棒性。由于该算法是通过检测在载频处的瞬时能量谱的跳变来实现2DPSK信号的解调,所以该算法不需要进行专门的载波相位恢复、符号定时,且具有较好的抗噪性能,实现起来简单。 相似文献
