公允价值会计能否放大银行体系的系统性风险

宏观审慎监管框架下公允价值会计被认为是顺周期机制,放大了银行体系的系统性风险而广受诟病。本文尝试从正向冲击和逆向冲击角度研究公允价值是否存在放大作用。研究发现两类冲击下系统性风险均存在;公允价值会计作用不对称,逆向冲击下放大了系统性风险,正向冲击下作用不明显;进一步分析逆向冲击的作用渠道时发现,市场流动性不足是放大作用的显著原因,银行以公允价值计价的风险敞口和资本充足率对放大作用没有显著影响。     

The effects of the Asian crisis, corporate governance and accounting system on the valuation of book value and earnings

This paper examines the value relevance of earnings and book value in four Asian countries, Indonesia, South Korea, Malaysia and Thailand, in the period surrounding the Asian financial crisis. Specifically, we examine the impact of the economic environment on the value relevance of book value and earnings. We also examine the effects of corporate-governance mechanisms and the type of accounting system together with the economic environment on the value relevance of accounting numbers. Our results indicate that the value relevance of earnings in Indonesia and Thailand was significantly reduced during the Asian financial crisis while the value relevance of book value increased. In Malaysia, the value relevance of both earnings and book value decreased during the crisis. In Korea, neither book value nor earnings was significantly impacted by the crisis. Our results indicate that the level of corporate-governance mechanisms has an impact on the extent of changes in the value relevance of book values, but not earnings. Specifically, the value relevance of book value declines when corporate governance is weak. Finally, our results indicate that accounting systems (i.e., IAS or tax-based) also affect the extent of changes in the value relevance of book value resulting from the crisis.

中外银行业操作风险比较研究

本文从国内外银行业操作风险损失事件分类数据和部门分类数据入手,采用案例分析法对中外银行业操作风险进行比较分析研究,发现我国银行操作风险集中在内部欺诈。中外典型案例的分析进一步说明了我国操作风险严重且集中的原因:信用体制和法律制度急需建立和完善;银行业内控制度和激励制度存在弊端;银行业仍然是分业经营模式,而且产品结构单一。     

会计信息的信贷决策有用性:基于所有权制度制约的研究

本文在我国制度背景下以两阶Logit回归模型考察我国会计信息的信贷决策有用性。模型包括银行信贷决策的会计财务指标,也包括所有权性质等制度因素。结果表明,会计信息可以降低信贷决策中信息不对称程度,但是信贷决策有用性在所有权制度层面被削弱,主要源于企业与银行均为政府终极所有时银行监督缺位。银行信贷决策中是否使用会计信息不单单是会计信息质量问题,也受所有权制度约束。     

Value relevance of earnings: Evidence from Middle Eastern and North African Countries

Researchers as well as regulators are increasingly more interested in enhancing their understanding of the factors that influence value relevance of reported earnings in financial statements. In the light of globalization and increased exposure to international accounting practices, a better comprehension of factors contributing to or reducing value relevance of earnings is essential. This paper investigates the value relevance of earnings and its components for a number of Middle Eastern and North African (MENA) countries. Additionally, the paper examines how differences in levels of mandated disclosures, source of accounting standards, and legal systems moderate the informativeness of earnings to investors. We find that mandated disclosure and source of accounting standard, (especially non-governmental source) are positively associated with earnings informativeness. Additionally, MENA countries with French civil law and systems have lower value relevance relative to countries in our sample with English and related legal codes. Further, the firms that have adopted international financial reporting standards have higher value relevance than firms in MENA countries which adhere to local standards.     

Critical thinking about creative accounting in the face of a recent scandal in the Turkish banking sector

In the last two decades, serious accounting scandals occurred in large companies (e.g. WorldCom and Enron) and in the banking sector (e.g. BCCI, Barings, Allied Irish Bank and Baninter). Then the problem of creative accounting with its legal and illegal aspects has come into agendas of business firms and governments. In this paper, a certain type of creative accounting practices (i.e. fraud) has been examined in the light of a Turkish case (i.e. the Imarbank Scandal). It has been found that deficiencies in the legal frameworks for banking and accounting, inadequacies in the autonomy of governmental regulation and supervision bodies, practical difficulties in enforcing legal and ethical rules due to the slow functioning of the judicial system are significant reasons for creative accounting practices in addition to the personal greed of both owners&top management of Imarbank and its customers. However, the intention and capability of political power in combating such kind of corruption are also crucial.     

Mandatory Adoption of IASB Standards: Value Relevance and Country-Specific Factors

The objective of this study is to investigate if the value relevance of European-listed companies increased after the mandatory application of International Accounting Standards (IAS)/International Financial Reporting Standards (IFRS) and how the value relevance of accounting information prepared under IAS/IFRS is shaped by the specific factors of the country in which companies are domiciled. Results show that the value relevance of financial information during the period companies applied mandatory IAS/IFRS is higher than for the period during which they applied local accounting standards. We also found that countries where accounting and tax are clearly separated show more relevant accounting information. Finally, we found that companies from countries with more legal and public enforcement mechanisms disclose less relevant accounting information under IAS/IFRS.     

Contagion risk in the Australian banking and property sectors

The Australian banking system emerged from the global crisis virtually unhurt, with most banks still profitable, adequately capitalized, and with AA credit ratings. Are there any risks or vulnerabilities in this success story? This paper analyzes Australia’s systemic banking risk and attempts to determine if this risk increased with the recent global crisis and whether this risk is related to the downturn experienced in the real estate market. We use extreme value theory to measure banks’ and property firms’ univariate Value at Risk, as well as multivariate intra-sector and inter-sector contagion risks. Of the 13 sectors analyzed, we find that the property sector exhibits the highest level of extremal dependence with the banking sector. The credit crisis significantly increased the probability of a bank or property firm crashing. Moreover, contagion risks significantly increased not only within the banking and property sectors, but also between those sectors.     

The value relevance of IFRS in the European banking industry

The main purpose of the paper is to investigate the market valuation of accounting information in the European banking industry before and after the adoption of IFRS, the latest version of International Accounting Standards. In a value relevance framework, we apply panel methods to a multiplicative interaction model, in which the partial effects of earnings and book value on share prices are conditional on the adoption of IFRS. According to our evidence, the IFRS introduction enhanced the information content of both earnings and book value for more transparent banks. By contrast, less transparent entities did not experience significant increase in the value relevance of book value.     

Measuring Value Relevance in a (Possibly) Inefficient Market

An interesting question in assessing value relevance of accounting variables is whether measures of value relevance are materially affected by market inefficiencies. We explore this question in two steps: First, we analytically examine the impact of market inefficiencies on the estimation of coefficients in value relevance regressions and derive a procedure that corrects potential biases caused by such inefficiencies. The procedure adjusts contemporaneous stock prices for future risk adjusted price changes, and yields value relevance coefficient estimates that capture both contemporaneous and delayed market reactions. Second, we apply this procedure to three types of studies that have attracted much attention in the accounting literature: 1) the value relevance of earnings and book values; 2) the value relevance of residual income value estimates; and 3) the value relevance of accruals and cash flows. We compare coefficient estimates obtained from conventional value relevance regressions with those from regressions employing our adjustment procedure, and find statistically significant differences in both level and return regression coefficient estimates. The magnitude of differences in coefficient estimates for return regressions is large enough to affect economic inferences. We find that coefficients of lagged price deflated residual income value estimates move significantly closer toward a predicted value of one implying a meaningful reduction of bias. Last, we find that cash flows now have significantly larger coefficient estimates than accruals consistent with their greater persistence.     

Implications of the ‘IAS Regulation’ for Research into the International Differences in Accounting Systems

Meek and Thomas (2004) call for research on the continued relevance of ‘rediscovered’ dichotomous accounting classifications. We provide such evidence by examining how developments surrounding the ‘IAS Regulation’ (1606/2002) influenced international differences in accounting systems in the European Union. Since a sufficient time series of actual post-2005 International Financial Reporting Standards (IFRS) reporting practice is not yet observable, we propose an initial re-classification of accounting systems based on evidence available to date, that is, the degree of implementation of the IAS Regulation in the Member States. Consistent with Nobes (1998), we find that the degree of public accountability to outside investors (the ‘public/private’ criterion) is becoming the primary differentiator for accounting systems in Europe, surpassing country-level variables such as legal system and culture. The distinction between consolidated and individual financial statements is the second emerging differentiator. While consolidated accounting is becoming more uniform across countries, cross-country cultural differences are most likely to persist in individual accounting. Based on our analysis we highlight two important areas of future research beyond the consolidated financial statements of listed firms (e.g. Nobes, 2005; Schipper, 2005). First, at the country level, the interaction of IFRS and individual financial statements will need to be reassessed. In addition, research could help introduce a degree of differentiation into financial reporting regulation for unlisted firms, because these firms are not a homogeneous group. Also, the convergence of national GAAP systems with IFRS will benefit from fresh research insights. Second, at the firm level, future research could analyze the extent to which the determinants and consequences of IFRS adoption, an area well researched for publicly traded firms (e.g. Cuijpers and Buijink, 2005), generalize to unlisted firms. Such research will help detect emerging patterns of accounting systems within an international context. It will generate insights into the disconnect of consolidated accounts from national influences, the degree of uniformity of consolidated accounts among international firms, the continued relevance of traditional classifications of international accounting systems for individual accounts and accounts of unlisted companies, and the convergence of national standards with IFRS.

Assessing the contribution of banks,insurance and other financial services to systemic risk

The aim of this paper is to contribute to the debate on systemic risk by assessing the extent to which distress within the main different financial sectors, namely, the banking, insurance and other financial services industries contribute to systemic risk. To this end, we rely on the $\mathrm{\Delta }\mathit{CoVaR}$ systemic risk measure introduced by Adrian and Brunnermeier (2011). In order to provide a formal ranking of the financial sectors with respect to their contribution to systemic risk, the original $\mathrm{\Delta }\mathit{CoVaR}$ approach is extended here to include the Kolmogorov–Smirnov test developed by Abadie (2002), based on bootstrapping. Our empirical results reveal that in the Eurozone, for the period ranging from 2004 to 2012, the other financial services sector contributes relatively the most to systemic risk at times of distress affecting this sector. In turn, the banking sector appears to contribute more to systemic risk than the insurance sector. By contrast, the insurance industry is the systemically riskiest financial sector in the United States for the same period, while the banking sector contributes the least to systemic risk in this area. Beyond this ranking, the three financial sectors of interest are found to contribute significantly to systemic risk, both in the Eurozone and in the United States.     

上市公司财务报告目的评估价值相关性研究——来自A股市场的经验证据

公允价值在会计准则中的广泛运用引致了以财务报告为目的的评估业务需求。本文选取了2004~2008年上市公司为研究样本,检验了以财务报告为目的的资产评估总体价值相关性以及基于资产减值测试的评估价值的市场反应。研究结果表明,新会计准则实施后的价值相关性显著提高,而资产减值的计提受投资者的关注度则有所减弱。这说明以财务报告为目的的评估有效地提高了会计信息的质量和信息含量,并在一定程度上抑制了滥用公允价值进行盈余管理的行为。从长远来看,深化经济的市场化程度,努力构建一个完整、统一、开放、充分竞争的市场,实现评估界与会计审计界的良性互动,同时加强会计监管及行业自律并对滥用公允价值及虚假评估行为予以严惩,仍是未来一段时期的重中之重。     

How accounting and auditing systems can counteract risk-shifting of safety-nets in banking: Some international evidence

This paper suggests that accounting and auditing systems can be effective devices to counteract tendencies for firm risk-taking associated with bank safety nets. Results are obtained from an international sample of publicly traded banks after controlling for other regulatory control devices for bank risk such as restrictions on banking activities, minimum regulatory capital requirements and official discipline. The efficacy of accounting and auditing systems in controlling bank risk diminishes with bank charter value and increases with moral hazard stemming from a country's deposit insurance. The results also indicate that accounting and auditing systems are complements for minimum capital requirements, but substitutes for restrictions on bank activities and official discipline.     

An economic capital model integrating credit and interest rate risk in the banking book

Banks often measure credit and interest rate risk in the banking book separately and then add the risk measures to determine economic capital. This approach misses complex interactions between the two risk types. We develop a framework where these risks are analysed jointly. Since banking book positions are generally not marked to market, our model is based on book value accounting. Our simulations show that interactions matter, and that ignoring them leads to risk overstatement. The magnitude of the errors depends on the structure of the balance sheet and on the repricing characteristics of assets and liabilities.     

论商业银行集团化经营的法律风险及其防控机制

集团化是现代银行最突出的特征之一。银行的集团化发展,可达到协同经营的目标,打破传统金融机构的竞争格局,使集团获得经营一体化带来的好处。但另一方面,复杂的股权关系、组织结构、内部往来、业务合作,也使得银行集团暴露于特殊的法律风险当中。在金融危机后,金融监管的严格化和法律环境的快速变化,使得银行集团面临的法律风险更为严峻。     

Credit Risk in Two Institutional Regimes: Spanish Commercial and Savings Banks

Although credit risk is an important factor that financial institutions must cope with, the determinants of bank problem loans have been little studied. Using panel data, we compare the determinants of problem loans of Spanish commercial and savings banks in the period 1985–1997, taking into account both macroeconomic and individual bank level variables. The GDP growth rate, firms, and family indebtedness, rapid past credit or branch expansion, inefficiency, portfolio composition, size, net interest margin, capital ratio, and market power are variables that explain credit risk. However, there are significant differences between commercial and savings banks, which confirm the relevance of the institutional form in the management of credit risk. Our findings raise important bank supervisory policy issues: the use of bank level variables as early warning indicators, the advantages of bank mergers from different regions, and the role of banking competition and ownership in determining credit risk.     

Bank portfolio exposure to emerging markets and its effects on bank market value

This study estimates a model of banking company equity returns taking into consideration book value and market value measures of their exposure to emerging markets debt. In this estimation, general systematic market factors, such as the rate of return on the S&P500 stock index and yields on a constant maturity 5-year Treasury note, are held constant such that the exposure variables are accounting for effects due to banks’ exposure to emerging market debt. The results, although not uniform among banking companies, support the hypothesis that the extent of exposure to emerging market debt are factored into the valuation of banking company equity contemporaneously. The inclusion of a market value indicator adds to the explanation of equity returns of some banks. It is also clear that knowing the extent of the exposure on a book value basis is important information alone that may allow investors to take account of or evaluate the effects of changes in banking company equity valuation from LDC debt exposures. We also perform an event study for three major debt crises to determine whether the market recognizes the effects of these events on bank valuation. The event study results show that there is little information from identifying the time period of the crises on banking company equity returns. Explanations for this are that the information of these possible crises has been embedded in bank changes in exposure and that the market valuation of the emerging market debt is already accounted for by our model.
