The central banker as prudential supervisor: Does independence matter?

We study whether central bank independence (CBI) and monetary policy arrangements can jointly influence the likelihood of policymakers assigning banking supervision to central banks. Our empirical analysis shows that, assuming a benevolent government, a higher degree of central bank operational (economic) independence is associated with a lower probability of supervisory powers being entrusted to the monetary authority. We interpret this result as deriving from governments’ fear of the risk of excessively discretionary monetary policy. However, there is evidence that – conditional on operational independence – central banks are more involved in supervision when they pursue tighter monetary policy goals (a specific aspect of political independence). Our interpretation is that the latter may represent a commitment to mitigate central banks’ discretion in the monetization of financial distress. Our study suggests that CBI can be relevant, not only for its alleged effects on macroeconomic variables, but also in influencing policymakers’ decisions on the allocation of banking supervisory powers.     

金融生态环境、负债的治理效应与债务重组:经验证据

本文研究金融生态环境、负债的治理效应与上市公司以债务人身份发生债务重组的关系,利用2001—2004年上市公司的数据研究发现,金融生态环境越差的地区的公司更可能发生债务重组;金融生态环境较好地区的上市公司的财务杠杆水平与债务重组之间的正相关关系更弱。这意味着,切实改善金融生态环境,提高金融机构等的经营独立性和信贷风险控制能力,促进公司负债发挥治理效应是非常重要的。本文还发现,存在机构投资者股东、高管持股比例更高和独立董事比例更高的公司更少可能发生债务重组,上市年龄越长的公司更可能发生债务重组。认为发展机构投资者,提高董事会的独立性和适当提高经理人基于股权的激励,并改进资本市场关于IPO公司质量审核的制度安排,可提高上市公司质量。     

Audit committee quality,auditor independence,and internal control weaknesses

In this paper we investigate the relation between audit committee quality, auditor independence, and the disclosure of internal control weaknesses after the enactment of the Sarbanes-Oxley Act. We begin with a sample of firms with internal control weaknesses and, based on industry, size, and performance, match these firms to a sample of control firms without internal control weaknesses. Our conditional logit analyses indicate that a relation exists between audit committee quality, auditor independence, and internal control weaknesses. Firms are more likely to be identified with an internal control weakness, if their audit committees have less financial expertise or, more specifically, have less accounting financial expertise and non-accounting financial expertise. They are also more likely to be identified with an internal control weakness, if their auditors are more independent. In addition, firms with recent auditor changes are more likely to have internal control weaknesses.     

Do independent directors cause improvements in firm transparency?

Although recent research documents a positive relation between corporate transparency and the proportion of independent directors, the direction of causality is unclear. We examine a regulatory shock that substantially increased board independence for some firms, and find that information asymmetry, and to some extent management disclosure and financial intermediation, changed at firms affected by this shock. We also examine whether these effects vary as a function of management entrenchment, information processing costs, and required changes to audit committee independence. Our results suggest that firms can alter their corporate transparency to suit the informational demands of a particular board structure.     

Defining and achieving financial stability

We discuss the thorny issue of how to define financial stability, and conclude that the best approach is to define the characteristics of an episode of financial instability, and to define financial stability as a state of affairs in which episodes of instability are unlikely to occur. We then discuss public policies to achieve financial stability, distinguishing between preventive and remedial measures, and explore the costs and benefits of such policies. We conclude with some comments on current issues in financial regulation, including Basel 2.     

Measuring the Independence of Central Banks and Its Effect on Policy Outcomes

Making the central bank an agency with the mandate and reputationfor maintaining price stability is a means by which a governmentcan choose the strength of its commitment to price stability.This article develops four measures of central bank independenceand explores their relation with inflation outcomes. An aggregatelegal index is developed for four decades in 72 countries. Threeindicators of actual independence are developed: the rate ofturnover of central bank governors, an index based on a questionnaireanswered by specialists in 23 countries, and an aggregationof the legal index and the rate of turnover. Legal independence is inversely related to inflation in industrial,but not in developing, countries. In developing countries theactual frequency of change of the chief executive officer ofthe bank is a better proxy for central bank independence. Aninflation-based index of overall central bank independence contributessignificantly to explaining cross-country variations in therate of inflation.     

Audit committee,board of director characteristics,and earnings management

This study examines whether audit committee and board characteristics are related to earnings management by the firm. A negative relation is found between audit committee independence and abnormal accruals. A negative relation is also found between board independence and abnormal accruals. Reductions in board or audit committee independence are accompanied by large increases in abnormal accruals. The most pronounced effects occur when either the board or the audit committee is comprised of a minority of outside directors. These results suggest that boards structured to be more independent of the CEO are more effective in monitoring the corporate financial accounting process.     

Do Markets Care about Central Bank Governor Changes? Evidence from Emerging Markets

Based on a new daily data set for 20 emerging markets over the period 1992–2006, we examine the reactions of foreign exchange markets, domestic stock markets, and sovereign bond spreads to central bank governor changes. We find that the replacement of a central bank governor negatively affects financial markets on the announcement day, which is in line with the hypothesis that newly appointed central bank governors suffer from a systematic credibility problem at the beginning of their tenure. We also find some evidence that changes in perceived central bank independence affect markets.     

Managing price and financial stability objectives in inflation targeting economies in Asia and the Pacific

Many central banks have adopted explicit objectives for financial stability, raising the possibility of trade-offs between price and financial stability objectives. Based on structural vector autoregressions that incorporate both monetary and macroprudential policy shocks for four inflation targeting economies in Asia and the Pacific, we analyse the role of each policy shock in explaining deviations from the other policy’s objective, by applying historical decompositions. The macroprudential measures used in the study affect credit extended to the private sector. We find that there are periods when macroprudential policy shocks have contributed to pushing inflation away from the central bank’s inflation target and when monetary policy shocks have contributed to buoyant credit, suggesting that there have been short-term trade-offs between price and financial stability objectives. However, we also find periods when macroprudential policy shocks helped stabilise inflation and monetary policy shocks contributed to financial stability.     

Financial distress,outside directors and corporate tax aggressiveness spanning the global financial crisis: An empirical analysis

We examine financial distress and tax aggressiveness spanning the global financial crisis (GFC) of 2008 and the impact of the interaction between board independence and firm-specific financial distress on tax aggressiveness. Our regression results show that both financial distress and the GFC are positively associated with tax aggressiveness. More importantly, we find that the positive association between financial distress and tax aggressiveness is magnified by the GFC. We also observe that the interaction between board independence and financial distress is positively associated with tax aggressiveness. Our results are robust to multiple measures of financial distress and tax aggressiveness.     

Corporate Governance and Efficiency: Evidence From U.S. Property–Liability Insurance Industry

This study examines the relation between corporate governance and the efficiency of the U.S. property–liability insurance industry during the period from 2000 to 2007. We find a significant relation between efficiency and corporate governance (board size, proportion of independent directors on the audit committee, proportion of financial experts on the audit committee, director tenure, proportion of block shareholding, average number of directorships, proportion of insiders on the board, and auditor dependence). We also find property–liability insurers have complied with the Sarbanes‐Oxley Act (SOX) to a large extent. Although SOX achieved the goal of greater auditor independence and might have prevented Enron‐like scandals, it had some unexpected effects. For example, insurers became less efficient when they had more independent auditors because the insurers were unable to recoup the benefits of auditor independence.     

Contagion of Capital Markets in CEE Countries: Evidence from Wavelet Analysis

We employed wavelets technology to investigate how and when contagion occurred on 10 Central and Eastern European financial markets in relation to Western European and US financial markets during 2000–2016 and their different reactions on the background of changes in their regulatory framework. We found that most of Central and Eastern European (CEE) capital markets showed contagion in relation to both Western European and US markets between 2005 and 2009, while Slovakian and Estonian markets showed no contagion. However, during 2010–2016, Croatian market showed de-contagion in relation to Western European market, while Bulgarian, Czech, Hungarian, and Polish markets showed de-contagion in relation to US market, increasing their independence.     

Banking Market Size Structure and Financial Stability: Evidence from Eight Asian Countries

Using commercial bank data from eight major Asian countries, we examine the relationship between the banking market size structure and the stability of financial institutions. We also analyze the effect of bank upsizing on the financial stability. Our results show that a rise in large banks’ market power, accompanying an increase in their market shares, lowers the capital adequacy of small banks. Small banks’ nonperforming loans and the possibility of their bankruptcy also increase as large banks’ market shares rise. We further show that larger banks tend to have lower capital adequacy ratios, liquidity ratios, and distance-to-default ratios. Our study suggests that large banks’ greater market shares are associated with small banks’ financial instability. Overall, these findings are consistent with the notion of the recent banking literature that has important antitrust policy implications.     

Two Naked Emperors?* Concerns about the Stability & Growth Pact and Second Thoughts about Central Bank Independence

This paper addresses two sets of issues relevant to current and prospective future E(M)U members: the consequences of the Stability & Growth Pact for fiscal‐financial sustainability and macroeconomic stability, and some risks associated with operational independence of the central bank. To be effective as a lender of last resort or to stabilise demand when short nominal interest rates are close to their zero lower bound, the central bank must coordinate and cooperate with the fiscal authorities. Central bank independence is unlikely to survive if such coordination and cooperation are not forthcoming.     

Macro prudential governance and central banks: Facts and drivers

The Great Crisis has highlighted the importance of establishing macro prudential architectures to address problems of financial stability. Central banks are always part of macro prudential settings, but their role is far from being homogeneous across countries, reflecting the fact that according to economic theory there are pros and cons in extending central bank influence to macro prudential supervision. The issue is then genuinely empirical: are there any meaningful drivers explaining the actual choices made by policymakers about the central bank's role in macro prudential governance?We identify three potential drivers – micro supervision involvement, monetary policy discretion, overall institutional independence – and test for their relevance, by analysing current institutional settings in 31 advanced and emerging market economies. We find that central bankers already in charge of micro supervision and less politically independent are more likely to get extended macro prudential powers; the same is true, if they have low monetary policy discretion, being constrained by a monetary stability objective. We interpret these results by using a political economy perspective.     

Audit committee financial expertise,corporate governance,and the voluntary switch from auditor-provided to non-auditor-provided tax services

A prime objective of the SOX is to safeguard auditor independence. We investigate the relation between audit committee quality, corporate governance, and audit committees' decision to switch from permissible auditor-provided tax services. We find that firms with more independent boards, audit committees with greater accounting financial expertise, higher stock ownership by directors and institutions, that separate the CEO and Chairman of the board positions, and with higher tax to audit fee ratios are more likely to switch to a non-auditor provider. Further, we document that firms are more likely to switch prior to issuing equity. We find no evidence that broad financial expertise on audit committees is related to the switch decision, suggesting that the SEC's initial narrow definition of expertise is more consistent with the objective of the SOX. Overall, our results suggest that accounting financial expertise and strong corporate governance contribute to enhanced audit committee monitoring of auditor independence.     

Financial supervision regimes and bank efficiency: International evidence

There exists a lively debate as for the appropriate architecture of the financial supervision regime, with a long list of theoretical advantages and disadvantages associated with each one of its key dimensions. The present study investigates whether and how bank profit efficiency is influenced by the central bank’s involvement in financial supervision, the unification of financial authorities, and the independence of the central bank. The results show that efficiency decreases as the number of the financial sectors that are supervised by the central bank increases. Additionally, banks operating in countries with greater unification of supervisory authorities are less profit efficient. Finally, central bank independence has a negative impact on bank profit efficiency.     

Monetary Policy and Financial Stability: Cross‐Country Evidence

We explain the heterogeneous response of central banks to financial stability risks based on a financial stability orientation (FSO) index, which reflects statutory, regulatory, and discretionary components of central banks' monetary policy frameworks. Our baseline results from a cross‐country panel of modified Taylor rules suggest that central banks with a high FSO increase their policy rates in response to elevated financial stability risks by 0.27 percentage points more than central banks with a low orientation. Back‐of‐the‐envelope calculations suggest that this policy rate differential translates into a reduced crisis probability but also into considerably lower inflation and output growth rates.

Monetary policy and financial stability in a banking economy: Transmission mechanism and policy tradeoffs

The 2008 global financial crisis demonstrated that monetary policy and financial stability policy are more highly interrelated than previously thought. This paper analyzes the interactions between these policies using a non-linear overlapping-generations model with financial frictions in the form of banking financial intermediation. The paper embeds negative externalities due to contagion effects in physical investments which creates the need for financial stability policy. We show how the monetary policy transmission mechanism depends on financial stability policy tools as well as on regulatory and institutional constraints.We find policy tradeoffs in trying to accomplish both monetary and financial stability targets. The central bank must take these tradeoffs into account when selecting the tools in its policy toolbox. Another important finding is the interchangeability of price stability and financial stability policy tools.
