金融中介、信息生产与金融风险膨胀新解   总被引:1,自引:0,他引:1  
苗文龙  冯涛 《金融评论》2010,2(1):101-110
现代金融中介理论认为金融中介具有信息生产功能。然而,金融创新背景下金融中介设计出大量的金融衍生工具,其风险状况呈级数增长,对整个体系的风险影响难以评估.在“太大而不能倒”的“潜规则”下,金融中介具有隐藏信息、利用信息优势以次充好的倾向。由此而造成的信息约束、信息处理严重影响了监管效率与金融稳定。雪上加霜的是.监管当局信息挖掘的能力未能跟上金融创新的步伐,风险积累态势不能准确监控,几乎坐以待“危”。因此,防危机、控风险之前提是:提高金融中介准确披露关键信息的责任,提升信息处理能力、金融预警能力等监管能力。  相似文献

本文根据外资银行和国有商业银行向在中国境内的外资企业提供的外币贷款和人民币贷款的数据 ,对金融中介及关系银行进行了实证研究。我们的主要结论有两点 :第一 ,企业与银行建立起来的金融业务关系越长久 ,那么其所获得的外币贷款利率就越低。这是对金融中介理论的支持。另外 ,外资控股、第三方担保等因素 ,也具有降低外币贷款利率的效应。第二 ,人民币贷款的利率随着外资企业与更多的银行建立和保持合作关系而降低。人民币贷款主要是由我国商业银行提供。如果商业银行间的竞争仅仅是用来作为信贷定价的主要决定因素 ,而不是用来推进金融创新 ,提供高质量的金融产品和服务 ,那么这将会损害我国商业银行的获利能力并进而影响金融系统的健康发展。  相似文献

Liquidity Preference and Financial Intermediation   总被引:4,自引:0,他引:4  
We examine the characteristics of optimal monetary policies in a general equilibrium model with incomplete markets. Markets are incomplete because of uninsured preference uncertainty, and because productive capital is traded infrequently. Rational individuals are willing to hold a liquid asset—"money"—at a premium. Monetary policy interacts with existing financial institutions to determine this premium, as well as the level of precautionary holdings. We show that inflation is expansionary, and that the optimal inflation rate is positive if there is no operative banking system (the Tobin effect). Otherwise, efficiency requires that money be undominated in its rate of return (the Friedman Rule).  相似文献

金融市场中要更多考虑参与主体"人"的因素。经典理论模型通常设定风险厌恶系数为不随年龄而变的常数。本文构建模型并运用微观和宏观数据,刻画和验证经济主体风险厌恶在生命周期中的时变特征。微观视角下风险厌恶受年龄正向影响,宏观视角下金融市场和行为风险厌恶均随平均年龄上升而上升。少年人口占比负向影响风险厌恶;中、老年人口降低风险偏好,风险态度趋于保守。风险厌恶在生命周期内存在时变性,表现为年龄越大风险厌恶越强,可谓"江湖越老,胆子越小"。这对于后续建模中设定风险厌恶可变系数有借鉴意义。年龄改变风险态度和风险资产组合,使得人口年龄结构系统性影响金融市场风险结构。因此,本文对于从人口学视角预判未来金融市场风险结构也具有一定参考价值。  相似文献

This note gives sufficient conditions for signing the effect of an increase in risk aversion on the optimal level of the choice variable selected by a decision maker under conditions of risk. The results are illustrated with a decision model taken from the theory of insurance demand.  相似文献

This paper presents evidence that the spread between the marginal product of capital and the return on financial assets is much higher in poor than in rich countries. A model with costly intermediation is developed. In this economy, individuals choose at each instant whether to work or to operate a technology. Entrepreneurs finance their business with their own savings and, if necessary, by borrowing from banks. I find that in this framework intermediation costs are not equivalent to a tax on the return of capital. The equivalence fails because costly intermediation affects not only the capital accumulation decision but also the occupational choice decision. I show that intermediation costs have important effects on per capita output and average business size in the economy. I conclude that taxing financial intermediaries can be a very bad policy for development. Journal of Economic Literature Classification Numbers: E20, E60, O11, O16.  相似文献

The finance literature supports an increasing role for behavioral aspects of investment decision-making. Among other factors such as demographics, personality type may influence risk tolerance as well. This paper explores the relationship between personality type dimensions of the Myers-Briggs Type Indicator (MBTI) and the moments approach to individual investor risk tolerance inherent in expected utility theory (EUT). Our study uses survey results to relate ex ante EUT tolerance for variance and skew to MBTI measures. Results indicate that personality type does explain individual ex ante EUT risk tolerance. Our results further suggest that the relationship between personality type and individual ex ante EUT risk tolerance is non-linear in form.  相似文献

Ambiguity Aversion and Incompleteness of Financial Markets   总被引:7,自引:0,他引:7  
It is widely thought that incomes risks can be shared by trading in financial assets. But financial assets typically carry some risk idiosyncratic to them, hence, disposing incomes risk using financial assets will involve buying into the inherent idiosyncratic risk. However, standard theory argues that diversification would reduce the inconvenience of idiosyncratic risk to arbitrarily low levels. This paper shows that this argument is not robust: ambiguity aversion can exacerbate the tension between the two kinds of risks to the point that classes of agents may not want to trade some financial assets. Thus, theoretically, the effect of ambiguity aversion on financial markets is to make the risk sharing opportunities offered by financial markets less complete than it would be otherwise.  相似文献

This paper studies a Diamond–Dybvig model of providing insurance against unobservable liquidity shocks in the presence of unobservable trades. We show that competitive equilibria are inefficient. A social planner finds it beneficial to introduce a wedge between the interest rate implicit in optimal allocations and the economy's marginal rate of transformation. This improves risk sharing by reducing the attractiveness of joint deviations where agents simultaneously misrepresent their type and engage in trades on private markets. We propose a simple implementation of the optimum that imposes a constraint on the portfolio share that financial intermediaries invest in short-term assets.  相似文献

本文基于期望效用理论构建新的家庭经济脆弱性分析框架,研究死亡风险对我国城市家庭消费的总体影响和异质性影响,为如何规避死亡风险的决策提供证据。结果表明:我国城市居民家庭普遍存在由死亡风险导致的经济脆弱性且比较严重,家庭经济脆弱性程度在20%以上的家庭占全部样本家庭的65%以上;死亡风险导致的家庭消费波动性显著高于消费水平的下降,这意味着采用保险来规避死亡风险比储蓄更有效。尽管家庭持有的寿险保障与面临的经济脆弱性匹配性较好,但寿险持有量不充分且寿险的有效性因家庭异质性存在差异,对3人家庭和35—44岁家庭作用最有效。本文的政策含义在于,脆弱性分析框架不仅能有效度量死亡风险对居民家庭消费和福利的影响,还可以回答居民家庭应如何选择死亡风险规避方式。  相似文献

Tests of Financial Intermediation and Banking Reform in China   总被引:2,自引:0,他引:2  
We develop tests of financial intermediation by national banking systems based on the expectation that, in commercial systems, financial intermediation should not be overly influenced by policy variables; should be greater in richer, faster growing industrial areas; and should direct funds to the best projects regardless of where deposits originate. Using Chinese provincial data from 1991 to 1997, we test whether financial reforms in the mid-1990s increased efficient intermediation by different financial institutions. We find that the importance of policy lending by state banks did not fall during the recent period and that lending by financial institutions did not respond to economic fundamentals. J. Comp.

This paper focuses on the delegation by bank managers of lending decisions to their agents, typically subordinate employees of the bank. We assume that agents may base their decisions about lending to borrowers on decisions other banks have made about these same borrowers. Then we show that there exist some lazy or negligent agents who neither directly monitor the borrower nor imitate the other banks if managers use relative performance evaluations as incentive schemes. In addition, it is shown that the learning or adjustment process of agents exhibits cyclical dynamics. Journal of Economic Literature Classification Numbers: D82, D83.  相似文献

Abstract. This research note uses two German datasets – the large‐scale German Socioeconomic Panel and unique data from own student questionnaires – to analyse the relationship between risk aversion and the choice for public sector employment. Main results are (1) more risk‐averse individuals sort into public sector employment, (2) the impact of career‐specific and unemployment risk attitudes is larger than the impact of general risk attitudes and (3) risk taking is rewarded with higher wages in the private but not in the public sector.  相似文献

This paper models capital flows in a rich–poor, two-country, two-asset, dual-risk economy with decreasing absolute risk aversion. The first risk is asset-specific. The second is political and dependent; i.e., related to particular asset outcomes. In this framework, the role of wealth in determining asset preferences is demonstrated, and the conditions for diversification are derived. The wealth effect and diversification conditions are applied to explain ongoing two-way capital flows in general as well as the apparent paradox of domestic capital flight with simultaneous inflows of foreign capital.  相似文献

This paper analyzes the impact of public debt on financial efficiency in an overlapping‐generations model. We argue that public debt may reduce intermediation costs by increasing the collateral of entrepreneurs. This effect is stronger, the stronger the non‐Ricardian component of public debt, i.e. the more it is associated with intergenerational redistribution. This effect can be interpreted as future generations acting as a guarantee for the loans provided to the entrepreneurs of the current generation. Furthermore, multiple growth paths may arise as low taxes increase private collateral, which in turn boosts growth via financial efficiency, while higher growth allows to maintain the same debt/GDP ratio with reduced taxes.  相似文献

The paper investigates a climate-economy model with an iso-elastic welfare function in which one parameter measures relative risk-aversion and a distinct parameter measures resistance to intertemporal substitution.We show both theoretically and numerically that climate policy responds differently to variations in the two parameters. In particular, we show that higher but lower leads to increase emissions control. We also argue that climate-economy models based on intertemporal expected utility maximization, i.e. models where = , may misinterpret the sensitivity of the climate policy to risk-aversion.  相似文献

反哺与分配:金融中介对经济增长的影响   总被引:1,自引:0,他引:1  
企业家能力与物质资本的结合可以促进经济增长,而这两种要素禀赋可能由不同的个体持有,因此,只有在个体间合理分配这两个要素的报酬,经济才能增长。本文给出微观机制来表明企业家能力异质的一群个体如何形成金融中介联盟,并在个体层面引进无穷期动态拉姆齐模型,个体通过优化自身的选择而促进整个社会的经济增长。我们还给出了富人扶持穷人的价格涓流效应和反哺涓流效应,来描述金融中介对经济增长以及收入分配影响的途径。  相似文献
