银行危机与货币危机共生性关系的实证研究

1 997— 1 998年的亚洲金融风暴中 ,银行危机与货币危机的同时爆发 ,即共生性危机的发生引发国际社会与学术界对这种现象的重新思考 :这种共生性现象是否确实具有普遍性 ?从理论的角度来看 ,银行危机与货币危机之间的确存在着一定的联系 ,但到目前为止 ,很少有研究从实证的角度来证明这种联系的确存在。正是基于此 ,本文从实证的角度出发 ,旨在揭示出银行危机与货币危机之间的确存在着相互影响 ,换言之 ,共生性危机的发生是具有显著性的。具体来说 ,本文以 1 975— 2 0 0 0年期间 53个国家危机的发生情况为研究对象 ,分别运用频率分布、信号法 ,以及概率回归模型来分析两种危机的共生性 ,并得到非常一致的结论 :在新兴市场国家中 ,银行危机与货币危机之间的确存在着明显的相互关系 ,同时银行危机更趋向于作为货币危机即将发生的同步或预警指标 ,而反之则不然。     

Inter-linkages between competition and stabilisation policies in the banking sector and stock market development in Europe

The banking sector and the stock market in Europe have been adversely impacted by a series of global financial crises over the last two decades. Major financial reforms were implemented to enhance the stability and competition within the banking sector. Measures were also implemented to create a vibrant stock market in Europe to stimulate economic growth in Europe. This study examines the interactions between stock market development, banking competition, and banking stability in European countries from 1996 to 2016. The purpose of the study is to understand the inter-linkages between these variables to ascertain the spillover impact of policy reforms in the banking sector on the stock market and vice-versa. Using a vector error-correction model, the study finds long-run and short-run inter-linkages between banking competition, banking stability, and stock market development in European countries. The study’s most robust result is that banking competition and banking stability stimulate stock market development in the long run. There is also some evidence that healthy competition in the banking sector and stock market development instils greater stability in the banking sector. The results suggest that policy measures put in place to create a vibrant stock market must include elevating banking competition and banking stability, with policymakers being cognizant that causality may be bidirectional.     

基于信息的双重危机模型及其在东亚危机中的应用

由于近来在新兴市场国家发生的一系列货币危机都同时伴随着银行危机的发生,要全面地理解这些货币危机,我们需要将具有微观基础的银行部门明确地纳入到货币危机的分析模型中去.该文通过应用基于信息的银行挤兑模型,建立了一个双重危机模型,并对诸如经济基本面的脆弱如何导致双重危机,以及银行危机和货币危机如何相互作用等问题,做出了内生化的解释.模型抓住了最近新兴市场货币危机的本质特征,并与最近东亚危机的经验事实非常符合.     

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.     

The size distribution of the banking sector and the effects of monetary policy

In recent years, the industrial organization of the banking system has received a large amount of attention. In particular, it is generally viewed that the size distribution of the banking sector has changed where it is dominated by a small number of large institutions. In this paper, we develop a model of imperfectly competitive banks that differ in terms of the size of their deposit base. Such differences are important for aggregate credit market activity and the effects of monetary policy. Notably, we explain how the optimal size distribution of the banking system involves trade-offs from distortions in credit markets due to imperfect competition across banking markets. Second, the effects of monetary policy on credit market activity are weaker in an economy dominated by a small number of large banks. Empirical analysis examining the role of concentration among the current members of the European Monetary Union is consistent with the predictions of the model.     

Liquidity and Twin Crises

This paper proposes a simple analytical framework for understanding 'twin crises'– i.e. crises where a currency crisis and banking crisis occur simultaneously and reinforce each other. The distinguishing feature of such crises is the spill‐over effects across financial institutions through collateral constraints, declines in market values of assets, currency mismatches on the balance sheet and the endogenous amplification of financial distress through asset sales. We explore the role of liquidity and the role of monetary policy in such crises. In particular, a central question is whether raising interest rates in the face of a twin crisis is the appropriate policy response. Raising interest rates has two countervailing effects. Holding the domestic currency becomes more attractive (other things being equal), but the value of the domestic banking system falls due to the fall in asset prices. When assets are marked to market, there is a potential for endogenously generated financial distress that leads to a collapse of asset prices, as well as the exchange rate. It is thus possible that raising interest rates can have the perverse effect of exacerbating both the currency crisis and the banking crisis.     

Liberalization,Regulatory Delays and Vulnerability to Systemic Banking Crisis

This work aims at contributing to the improvement of the early warning systems of banking crises using a new approach accounting for model uncertainty. We show that a multinomial logit model based on Bayesian model averaging (BMA) is a good strategy to predict banking crisis. To do this, we argue that differences in vulnerability to banking crisis can be largely explained by an asymmetry between financial market evolution and regulation update on a sample of 49 developed and developing countries between 1980 and 2010. When markets are liberalized, competition pushes bankers to take more risks and take advantage of regulatory delays thus increasing crises probabilities. Our empirical evidence supports that crisis probability is higher in country liberalizing their banking system when regulation is not updated. We developed an early warning system for systemic banking crises based on the multinomial logit model. Its main difference to existing prediction models and its contribution to the literature is that it is intended to identify and resolve what is called by Bussiere and Fratzscher [(2006). Towards a new early warning system of financial crises. Journal of International Money and Finance, 25(6), 953–973] as post-crisis bias in binomial models and to develop a new methodology of leading indicators selection based on BMA. Overall, our model predicts all banking crises during our sample period.     

Modelling upstream and downstream market power in bilateral oligopoly

This article develops a general model that estimates market power exertion in a bilateral market relationship for processors and retailers where each may also have market power in their primary input market and output markets, respectively. Monte Carlo experiments are used to generate industry data for market structures such as perfect competition, monopoly, monopsony, bilateral imperfect competition with an integrated processor/retailer, bilateral imperfect competition with separate processor and retailer, and bilateral imperfect competition with four adjacent upstream and downstream markets. Then, new empirical industrial organization models are estimated using the data with models that match the market structure under which the data were generated (true) and with models that reflect alternative market structures (alternative). The general model is derived using the production function approach without imposing the fixed proportion assumption. Monte Carlo simulation results indicate that the general model is preferred to alternative models that presume competitive behaviour by processors in primary input procurement and by retailers in the output market. Results indicate that less flexible models lead to biased market power estimates in the presence of market power in the corresponding input and output markets.     

Finance and unemployment: new panel evidence

The effect of credit market imperfections on unemployment is largely investigated in the context of financial crises. This paper shifts the focus toward financial development and structure in a panel of advanced and developing countries. Some important findings emerge. Unemployment increases with financial development and concentration in banking markets but decreases with market orientation, the effect is stronger in magnitudes for young workers than female ones. More rigid market regulation increases unemployment. These findings are particularly pronounced for countries with higher income, better developed financial sectors, lower income inequality, greater trade openness, higher democracy, and common-law systems.     

产出不确定,信息不对称与双重危机发生机制

本文构造了一个具有银行部门和消费—生产者微观基础的一般均衡模型,分析了新兴市场国家双重危机的发生机制。本文发现,下列条件可以引发双重金融危机:(1)一部分外国存款人在中期获得了关于东道国未来产出或币值的糟糕信号;(2)本国居民对未来产出或币值的不利信号反应过度而不再追加投资;(3)居民由于"动物情绪"不再追加投资。     

Optimal monetary policy with the cost channel and monopolistically-competitive banks

This paper studies the optimal nominal policy interest rate in a model with the cost channel and imperfect competition in the banking sector. Due to this market power, the interest rate on deposits is relatively low; in particular it is lower than the policy interest rate. This, in turn, leads to a suboptimal level of deposits and, as a result, to a low level of intermediation. Deviations from the Friedman Rule are optimal in this setup regardless of the assumption about price rigidity; since households can hold their assets in the form of cash or deposits, taxing money, which is an imperfect substitute for deposits, is optimal in order to increase the level of deposits and encourage intermediation. The main results of the paper are robust to the introduction of market power in the loan market as well as stickiness in both the deposit and the loan markets.     

MARKET COMPETITION BEFORE AND AFTER BANK MERGER WAVE: A COMPARATIVE STUDY OF KOREA AND JAPAN

Abstract. Reflecting recent merger trends in the banking industry of Korea and Japan, this paper examines the degree of competition before and after the bank merger wave. Two major implications are derived from empirical analyses. First, high levels of banking market competitiveness are detected after mergers in both the Korean and Japanese metropolitan areas. Second, although the level of market competition remains low throughout Japanese local cities, it is competitive compared with the metropolitan area of Korea. This paper concludes that market concentration brought about by bank mergers does not always result in low competitiveness.     

Banking Sector Performance in Latin America: Market Power versus Efficiency

Since the mid‐1990s the banking sector in the Latin American emerging markets has experienced profound changes due to financial liberalization, a significant increase in foreign investments, and greater merger activities often occurring following financial crises. The wave of consolidation and the rapid increase in market concentration that took place in most countries has generated concerns about the rise in banks' market power and its potential effects on consumers. This paper advances the existing literature by testing the market power (Structure–Conduct–Performance and Relative Market Power) and efficient structure (X‐ and scale efficiency) hypotheses for a sample of over 2500 bank observations in nine Latin American countries over 1997–2005. We use the Data Envelopment Analysis technique to obtain reliable efficiency measures. We produce evidence supporting the efficient structure hypotheses. The findings are particularly robust for the largest banking markets in the region, namely Brazil, Argentina, and Chile. Finally, capital ratios and bank size seem to be among the most important factors in explaining higher than normal profits for Latin American banks.     

WHAT MAKES INTERNATIONAL CAPITAL FLOWS PROMOTE ECONOMIC GROWTH? AN INTERNATIONAL CROSS‐COUNTRY ANALYSIS

This paper re‐examines the relationship between international capital flows and economic growth within the context of various ‘conditional factors’ that possibly have the potential to influence such relationships. It achieves this by employing panel data for 80 countries that cover 1976–2007. International capital inflow is broken down into foreign direct investments (FDI) and foreign portfolio investments (FPI). We find interesting evidence that only FDI has a positive effect on growth and that FPI has an unfavorable, if not negative, effect on growth. The conditional variables of banking liberalization, high‐income level, twin crises, lower corruption, and human capital mitigate the positive impacts of FDI on growth. In contrast, the middle‐income level and good shareholder protection have a positive effect. As concerns FPI, the level of financial liberalization, being in a Latin American region, the wealth of countries, and market governance all influence the way that FPI affects growth, whereas the conditional variables of twin crises and human capital do not influence the effect of FPI on economic growth.     

Tariff Reductions in the Presence of Foreign Direct Investment

This paper argues that the welfare effects of trade liberalization in the presence of foreign direct investment obtained under perfect competition cannot be extended to imperfectly competitive markets. In the Heckscher-Ohlin model, trade liberalization may be paradoxically immiserizing when the traditional welfare-increasing result is corrected for the change in foreign capital revenue. Under imperfect competition this cannot occur, except under rather implausible assumptions. Indeed, a tariff reduction is expected to increase welfare when the welfare indicator is corrected for the presence of foreign capital, regardless of the type of market structure and the form of competitive rivalry.     

The Italian Banking Structure in the 1990s: Testing the Multimarket Contact Hypothesis

The multimarket contact hypothesis holds that more contacts between firms competing in the same markets may induce more collusion. This paper tests the hypothesis for the Italian banking market, analysing the behaviour of the largest Italian banks from 1990 to 1996. Market rivalry is gauged by changes in loan market shares and interest rates in each Italian province. We estimate the effects of increasing multimarket contacts, concentration indicators, banks' costs and loan demand on variations in market shares and interest rates. No support is found for the multimarket contact hypothesis. Geographical overlap in banking is positively correlated with changes in market shares, confirming the thesis of an overall increase in competition within the Italian banking system. Greater multimarket links also seem to correspond to lower lending rates.

商业银行竞争与公司盈余管理

本文以2007—2017年我国上市公司为研究样本,利用银保监会公布的商业银行在各城市开设分支机构的数据,构造地级市区域银行竞争指标,检验了商业银行竞争程度与公司盈余管理之间的关系。研究发现,银行业竞争性的市场结构能够有效降低企业盈余管理水平。对机制的考察表明,企业会计信息质量的提高得益于银行债权人治理作用不断加强。本文选择2009年银保监会放开银行设立分支机构限制的政策作为外生事件,并通过构造工具变量等方法进一步验证了研究结论。本文的结果从债权人的角度丰富了企业会计信息质量的文献,同时对银行竞争方面的研究做出了有益补充。     

Financial openness,market structure and private credit: An empirical investigation

Consistent with recent theoretical models, this paper finds that financial openness has a positive effect on private credit in economies characterized by a competitive banking sector, but that this effect vanishes and even becomes negative in economies with imperfect banking competition.     

Banking structure and financial stability: a comparison of Chinese and German banking systems

In the process of financial globalization and diversification, the issue of financial stability has become heated all over the world. This paper attempts to uncover the delicate relationship between banking structure and financial stability by comparing and analyzing the situation of the Chinese and German banking systems. This paper suggests that (i) the trade-off between competition and concentration in banking industry is a vital factor to maintain financial stability and (ii) concentration is not always a bad thing for financial stability, especially in banking systems with discontent bank performance.     

中国汽车工业市场结构变迁及其成因

为揭示我国汽车工业的结构演进过程，以更好地引导发展，本文运用产业组织理论对我国汽车工业市场结构变迁及其成因进行了梳理。研究表明，我国汽车工业发展史可分为五个阶段，各阶段的市场结构特点、成因、竞争程度均有很大差异，其中政府和市场影响呈现此消彼长的局面，但政府角色更关键。政府一系列行为旨在塑造由国营车企主导的高集中度市场结构，但行政主导式的高集中寡占型市场结构由于缺乏有效市场竞争，因而市场结构始终与较强的市场势力和不完全竞争相联系。此外，本文还运用博弈论探讨了现阶段“多角联盟”下的企业行为，分析表明该结构下的价格合谋更具稳态性。
