国有企业融资效率与银行危机相关问题研究

企业融资效率是指企业融资能力的大小。企业融资低效率是我国经济运行的突出特征。多投入及多消耗资本, 使经济运行对银行体系形成一种自下而上的资金需求压力, 最终也拖垮了银行, 导致信贷萎缩, 使微观问题传递和集中到宏观上来。     

货币危机与银行危机共生因子实证分析——国别比较的视角

共生危机的事实表明,货币危机与银行危机共生的现象在不同类型的国家均可能出现,而非某一类国家所特有的现象.基于对共生性货币银行危机触发机制国别差异的考察,文章在对1980～2006年间60个国家共生危机发生情况识别的基础上,分别构建了工业化国家和发展中国家共生危机生成的逐步Logistic回归模型.研究表明,工业化国家的共生危机主要是经济中各类矛盾累积的结果,发展中国家则主要源于本国制度缺陷,而采用滞后一期的变量来解释工业化国家共生危机时,效果不显著.     

James Steuart and the making of Karl Marx’s monetary thought

Abstract

This paper analyses the influence of James Steuart on Karl Marx’s monetary thought. It deals more specifically with Marx’s rejection of an automatic mechanism that links variations in the quantity of money to their direct impact on prices. Steuart’s pioneering discoveries in economics inaugurate an anti-quantity theory tradition that Marx supported and which fed his own conception of money and credit. Here, we deal with the criticism of the assumptions of the quantity theory of money (QTM), the specifically social character of labour which creates exchange value, the distinction between the functions of money, the difference between income spending and capital advances, and the difference between simple circulation and reflux of money credit.     

Theories of Soft Budget Constraints and the Analysis of Banking Crises

This paper proposes a new taxonomy for classifying models of soft budget constraints which allows identification of two classes of models. Distinguishing between these classes of models is useful, as they yield SBCs in differing circumstances and have differing theoretical and policy implications. The taxonomy is used to motivate an area of economic theory in which SBC models can yield novel insights: the analysis of banking crises. A model is presented in which SBCs arising from creditor passivity have implications for the question of the appropriate policy for dealing with bad debts on troubled banks' balance sheets. The paper also compares the implications of the two classes of SBC models for the analysis of banking crises.     

Firm size,credit scoring accuracy and banks’ production of soft information

Research on SME bank financing generally assumes that smaller firms are more opaque from a lender’s perspective. We propose that the discriminatory power of credit scoring models can be thought of as a proxy for firm opaqueness, given that when these models perform poorly, lenders must invest in the production of ‘soft information’ to supplement the financial data used in these models. Measuring the discriminatory power of probit default models across quintiles of the Irish SME size distribution, we show that our proxy for firm opaqueness increases monotonically as firms get smaller. This finding supports an assumption that is the starting point to a wide strand of literature on SME bank financing. Our findings can also be interpreted as providing an insight to the literature on the determinants of banks’ choice of lending technology. While smaller banks may, as found in a substantial previous literature, produce larger amounts of ‘soft information’ due to their organizational advantages, they may also do so out of necessity: hard-information-based default modelling is less effective among smaller firms, thereby forcing banks that lend to these borrowers to invest more in relationship banking technologies to retain competitiveness.     

The Fable of the Allegory: The Wizard of Oz in Economics: Comment

Although recent research strongly suggests that L. Frank Baum did not write The Wonderful Wizard of Oz as a monetary or political allegory, the Populist-parable interpretation of his book remains a tremendous teaching tool in economics classes. The author offers some background on the rise and fall of the Populist interpretation, in recognition of students' natural curiosity about Baum's intentions. He also offers a classroom-ready version of the parable that synthesizes several different versions of that interpretation.     

Portugal’s banking and financial crises: unexpected consequences of monetary integration?

Portugal’s current financial crisis might be related to a banking crisis resulting from joining the Euro. The new-currency eliminated the exchange rate risk, but not the credit or liquidity risks within the Euroarea. However, Portuguese banks acted as if all of these risks had disappeared. They began pumping money in Portugal, by borrowing intensively in Euros abroad at low interest rates. The ensuing liquidity generated a capital-flow bonanza boom that culminated in a bust phase. Private and sovereign debt dramatically increased, which further soared when the government rescued banks. Portugal was then compelled to take extreme measures to address extraordinary debt-levels.     

Information production, banking industry structure and credit allocation

We analyse credit allocation when limited-liable banks can engage in costly information production about borrowers. When perfectly diversified credit portfolios cannot be constructed, we show that credit allocation depends on bank capital and the number of banks that can operate in the same market. A concentrated banking industry, one where bank capital is held by few banks, is shown to lead to credit allocation closer to the social optimum. Moreover, in the absence of banking industry consolidation, we find that the removal of intra-state entry barriers reduces welfare and not all independent banking organizations that were viable in formerly protected markets remain so when markets are integrated.     

银行业结构影响中小企业信贷能力？——基于分层线性模型实证

中小企业融资问题引起了我国普遍关注。基于wind数据库,利用分层线性模型考察了企业规模与银行业结构对中小企业信贷能力的影响,并引入了商业信用环境变量,研究不同商业信用环境下,该影响是否会发生变化。研究发现,企业规模越大,银行业结构越分散,企业信贷能力越强,但该影响程度随着商业信用环境的提高而减弱。本研究对于如何提高中小企业信贷能力具有重要参考意义。     

Adverse risk interaction: An integrated approach

This paper studies adverse interaction between credit and market risk. We develop a comprehensive Merton-type model, in which payment ability of borrowers is driven by the overall economic growth, while the level of their liabilities is sensitive to market variables. To illustrate the model, we apply numerical simulations to estimate credit, market and integrated Value at Risk from the loss distribution using industry-wide data from the Serbian banking sector. We show that—even after accounting for presence of market risk in the banking book—the total risk remains higher than the simple sum of credit and market risk. The results emphasize the importance of integrated approach to assessment of economic capital.     

Crises and exchange rate regimes: time to break down the bipolar view?

We revisit the link between crises and exchange rate regimes (ERR). Using a wide panel of 90 developed and developing countries over the period 1980–2009, we find that corner ERR are not more prone to crises compared to intermediate ERR. This finding holds for different types of crises (banking, currency and debt), and is robust to a wide set of alternative specifications. Consequently, we clearly break down the traditional bipolar view: countries that aim at preventing crisis episodes should focus less on the choice of the ERR, and instead implement sound structural macroeconomic policies.     

Tracing the causes of the banking crisis

We add the Bernanke–Gertler–Gilchrist model to a modified version of the Smets–Wouters model of the U.S. in order to explore the causes of the banking crisis. The innovation of this article is estimating the model using unfiltered data allowing for non-stationary shocks in order to replicate how the model predicts the crisis. We find that ‘traditional shocks’ account for most of the fluctuations in macroeconomic variables; the non-stationarity of the productivity shock plays a key role. Crises occur when there is a ‘run’ of bad shocks; based on this sample they occur on average once every 64 years and when they occur around 10% are accompanied by financial crisis. Financial shocks on their own, even when extreme, do not cause crises – provided the government acts swiftly to counteract such a shock as happened in this sample.     

关于货币危机后经济衰退的经验分析

文章以1990年以来的近200次货币危机为样本,对货币危机后的经济衰退进行了经验分析.研究发现,危机前的经常账户状况、外债余额占GDP比例、国际流动性指标等经济变量以及危机后的汇率制度都不会显著影响到危机后的经济衰退.另外,危机后的经济衰退与危机国政府在危机中是否抛售外汇储备、是否采取汇率贬值都没有明显关系.但是经济分析的结果表明,危机前的失业率和汇率制度以及危机中是否提高利率等因素对危机后的经济衰退有显著作用.     

基于极值相依性的金融危机共生强度研究

共生性危机是金融危机研究的热点之一,经验表明不同国家同时爆发两种危机的可能性不同,但尚缺乏对危机共生强度的定量研究;copula是刻画变量之间非线性相互关系的重要方法,但函数选择目前仍缺少依据。针对这两个问题,文章由极值相依性模型推导出数十种生存copula函数的共同渐近形式,基于此构建危机共生指数,并给出一套系统检验共生性强弱及度量共生强度的方法。对1994-2009年十个新兴经济体的实证研究表明:各国的危机共生强度各异,俄罗斯、新加坡、智利和中国的金融危机具有弱共生性;爆发共生性危机的可能性很大程度上由金融自由化决定;外汇市场或金融市场遭受攻击时的极端风险更易在两者之间传导;通过本币升值稳定物价的宏观调控政策将增加双重危机爆发的可能性;控制外汇市场和银行业经营的不稳定因素是抑制共生性危机的重要途径,但在印度和中国的效果可能有限。
