Fiscal Consequences of Paying Interest on Reserves

We review the role of the central bank's balance sheet in a textbook monetary model and explore what changes if the central bank is allowed to pay interest on its liabilities. When the central bank (CB) cannot pay interest, away from the zero lower bound its (real) balance sheet is limited by the demand for money. Furthermore, if securities are not marked to market and the central bank holds its bonds to maturity, it is impossible for the CB to make losses, and it always obtains profits from being a monopoly provider of money. When the option of paying interest on liabilities is allowed, the limit on the CB's balance sheet is lifted. In this case, the CB is free to take on interest‐rate risk – for example, by buying long‐term securities and financing those purchases with short‐term debt that pays the market interest rate. This is a risky enterprise that can lead to additional profits but also to losses. To the extent that losses exceed the profits of the monopoly operations, the CB faces two options: either it is recapitalised by Treasury or it increases its monopoly profits by raising the inflation tax.     

地方政府债券置换对银行信贷及货币供给的影响

通过构建基于商业银行资产负债结构的地方债置换分析框架,研究表明,地方债置换将通过商业银行资产结构在贷款与债券之间的配置调整影响货币供给,它将使银行可贷资金增加,并导致贷款规模的变化,在贷款创造存款的信用放大机制下,引起货币供应量的变化,进而造成货币政策的扩张(收缩).贷款市场的供求弹性将决定地方债置换的扩张效应或收缩效应.在经济增长放缓、银行为弥补持有地方债收益下降、地方债纳入货币政策工具的抵押品和质押品范围的情况下,地方债置换具有货币政策扩张效应.为减少地方债对金融市场的冲击,央行需密切监测商业银行资金运用情况,提高货币政策操作的针对性,并加强同财政政策的协同配合.     

Actuarial pricing of deposit insurance

Using a pricing formula for options on coupon bonds (Jamshidian [1989], El Karoui and Rochet [1990]) we are able to compute the actuarial pricing of deposit insurance for a commercial bank. Our formula takes into account the maturity structure of the bank's balance sheet, as well as market parameters such as the term structure of interest rates and the volatilities of zero coupon bonds. The relation with asset liability management methods is explored.     

企业发债和贷款期限的差异化:基于增量法的实证研究

已有文献主要从资产负债表法来实证研究企业负债期限结构的影响因素,本文以我国企业在1998～2008年企业发行的各类债券和银行贷款为研究对象,运用增量法从企业财务特征和债务契约属性等方面对企业增量债务期限的影响因素进行实证研究,采用了GMM计量方法,并通过对比分析筛选出了影响企业发债和贷款期限差异化的关键因素。研究表明:企业规模越大,利润率越高,具备担保,信用评级和授信比率越高,其债务期限越长。企业若选择发债,债务期限会延长,而选择银行贷款则企业债务期限会缩短。     

Optimal Bank Reorganization Policies and the Pricing of Federal Deposit Insurance

Optimal dynamic regulatory policies for closing ailing banks and for deposit insurance premia are derived as functions of the rate of flow of bank deposits, and interest rate on deposits, the economy's risk-free interest rate, and the regulators' bank audit/administration costs. Under competitive conditions, the threshold assets-to-deposits ratio below which a bank should be optimally closed is shown to be greater than or equal to one. Optimal deposit insurance premia and probabilities of bank closure are shown to be nondecreasing in the bank's risk on investment and nonincreasing in the bank's current assets-to-deposits ratio.

Aligning Incentives at Systemically Important Financial Institutions: A Proposal by the Squam Lake Group

To address the moral hazard problem that can motivate bank executives to take excessive risks and to fail to raise capital when needed, a group of 13 distinguished financial economists recommends that systemically important financial institutions be required to issue contingent convertible debt (CoCos) and to hold back a substantial share—as much as 20%—of the compensation of employees who can have a meaningful impact on the survival of the firm. This holdback should be forfeited if the firm's capital ratio falls below a specified threshold. The deferral period should be long enough—the authors suggest five years—to allow much of the uncertainty about managers' activities to be resolved before the bonds mature. Except for forfeiture, the payoff on the bonds should not depend on the firm's performance, nor should managers be permitted to hedge the risk of forfeiture. The threshold for forfeiture should be crossed well before a firm violates its regulatory capital requirements and well before its contingent convertible securities convert into equity. The Swiss Bank UBS has paid bonuses to its top 6,500 executives that have been structured in exactly this way. Management forfeits its deferred compensation if the bank's regulatory capital ratio falls below 7.5%, and its contingent convertible debt is set up to convert into equity if the bank's capital ratio falls below 5%.     

Banks as lenders and shareholders: Evidence from Japan

This paper examines the effects of the main bank's equity–debt structure, (i.e., equity stakes and debt claims) on firm performance and financial policies in Japan over the period 1977–1987. Results show that firms with main bank equity stakes have lower performance than those without. However, among firms with main bank equity stakes, the equity–debt structure of claims has a positive effect on firm performance. The positive effect of the main bank's equity–debt structure is found to be greater in group-affiliated firms than in independent firms. The main bank maximizes its own interests by charging a higher interest rate when its equity stakes are relatively less than its debt claims and by prompting firms to pay more dividends when its equity stakes are relatively high.     

The response of the external finance premium in Asian corporate bond markets to financial characteristics,financial constraints and two financial crises

Empirical investigation of the external finance premium has been conducted on the margin between internal finance and bank borrowing or equities but little attention has been given to corporate bonds, especially for the emerging Asian market. In this paper, we hypothesize that balance sheet indicators of creditworthiness could affect the external finance premium for bonds as they do for premia in other markets. Using bond-specific and firm-specific data for China, Hong Kong, Indonesia, Korea, Philippines, Singapore and Thailand during 1995–2009 we find that firms with better financial health face lower external finance premia in all countries. When we introduce firm-level heterogeneity, we show that financial variables appear to be both statistically and quantitatively more important for financially constrained firms. Finally, when we examine the effects of the 1997–1998 Asian crisis and the 2007–2009 global financial crisis, we find that the sensitivity of the premium is greater for constrained firms during the Asian crisis compared to other times.     

The Value of Deposit Insurance in the Presence of Interest Rate and Credit Risk

In this paper we employ the theory of the term structure of interest rates and the pricing of interest contingent contracts to determine the fair value of insurance for depository institutions. The balance sheet of a bank is taken to consist of long and short positions in various fixed income securities. Deposit insurance for the bank is a put option on the value of the assets. The value of deposits, assets, the implied exercise price of the put and the value of the put are all determined simultaneously as part of the same valuation solution. The approach is developed initially for a single‐state term structure. It is extended to incorporate credit risk on bank assets.
The most important policy implication is that for a bank whose assets are longer term than its liabilities and whose borrowers are not excessively leveraged the properly calculated, risk‐adjusted deposit insurance premia are increasing functions of the level of interest rates. Sensitivity analyses also treat such factors as the bank's deposit to asset ratio, duration gap, interest volatility, the volatility of assets backing the bank loans, and the bank's borrowers' debt to equity ratio.     

Why Money Growth Determines Inflation in the Long Run: Answering the Woodford Critique

Woodford argues that it is not appropriate to regard inflation in the steady state of New Keynesian models as determined by steady‐state money growth. Woodford instead argues that the intercept term in the monetary authority's interest rate policy rule determines steady‐state inflation. In this paper, I offer an alternative interpretation of steady‐state behavior, according to which it is appropriate to regard steady‐state inflation as determined by steady‐state money growth. The argument relies on traditional interpretations of the central bank's power in the long run and appeals to model properties that are common to textbook and New Keynesian analysis. According to this argument, the only way the central bank can control interest rates in the long run is via affecting inflation, and its only means available for determining inflation is by determining the money growth rate.     

全球央行购买公司债的原因、效果及启示

中央银行购买公司债是次贷危机后货币政策理论的一项伟大创新和重要实践探索。通过对迄今为止购买过公司债的日本央行、英国央行和欧洲央行的公司债购买计划进行的系统梳理和总结,以及对中央银行购买公司债的理论依据进行分析,提出中央银行购买公司债的六大传导机制。对中央银行购买公司债的经验进行阐述后认为,鉴于当前实体经济依然存在融资难融资贵问题,中国央行在必要时也可实施公司债购买计划,以降低信用利差并提高货币政策传导效率。     

Taylor rules and the term structure

The expectations model of the term structure has been subjected to numerous empirical tests and almost invariably rejected, with the failure generally attributed to systematic expectations errors or to shifts in risk premia. Rules for monetary policy designed along the lines of Taylor [1993. Discretion versus policy rules in practice. Carnegie-Rochester Conference Series on Public Policy 39, 195-214] specify that the central bank adjusts short-term yields in response to deviations of inflation and output gaps from target level. Such rules give a good empirical account of the behavior of the short-term interest rate. Combining the Taylor rule and expectations theory, it is possible to generate—along lines pioneered by Campbell and Shiller [1987. Cointegration and tests of present value models. Journal of Political Economy 95, 1062-1088]—a series of theoretical long-term interest rates. When such theoretical rates are calculated for the US over 1980-2004, considerable support for the expectations theory emerges.     

On the optimal monetary policy response to noisy indicators

We describe a behavior of a central bank when its measures of current inflation and output are subject to measurement errors, in a framework of optimizing models with nominal price stickiness. In our model, a central bank sets the interest rate equal to its current estimate of the so-called Wicksellian natural rate of interest. This is shown to imply that the interest rate responds to the central bank's estimates of both current inflation and output gap, as advocated by Taylor (1993). It is also shown that the noise contained in the indicators justifies a degree of policy cautiousness. A reduced-form representation of optimal policy should exhibit interest-rate smoothing, which is often found in the empirical literature on monetary policy reaction functions.     

A Limited Central Bank

The President of the Philadelphia Federal Reserve Bank from 2006–2015 discusses the Fed's essential role as preserver of the currency's purchasing power and how the institution might be improved to better fulfill that role. To that end, the author proposes the imposition of four limits on the central bank that, by restricting its discretion, can be expected to improve outcomes and accountability.

• First, limit the Fed's monetary policy goals to a narrow mandate in which price stability is the sole, or at least the primary, objective;
• Second, limit the types of assets that the Fed can hold on its balance sheet to Treasury securities;
• Third, limit the Fed's discretion in monetary policymaking by requiring a systematic, rule‐like approach; and
• Fourth, limit the boundaries of its lender‐of‐last‐resort credit extension.

These changes, by creating a more limited central bank, would help preserve the central bank's independence, thereby improving the effectiveness of monetary policy. They would also make it easier for the public to hold the Fed accountable for its policy decisions.     

A model of unconventional monetary policy

We develop a quantitative monetary DSGE model with financial intermediaries that face endogenously determined balance sheet constraints. We then use the model to evaluate the effects of the central bank using unconventional monetary policy to combat a simulated financial crisis. We interpret unconventional monetary policy as expanding central bank credit intermediation to offset a disruption of private financial intermediation. Within our framework the central bank is less efficient than private intermediaries at making loans but it has the advantage of being able to elastically obtain funds by issuing riskless government debt. Unlike private intermediaries, it is not balance sheet constrained. During a crisis, the balance sheet constraints on private intermediaries tighten, raising the net benefits from central bank intermediation. These benefits may be substantial even if the zero lower bound constraint on the nominal interest rate is not binding. In the event this constraint is binding, though, these net benefits may be significantly enhanced.     

Inflation targeting,credibility, and non-linear Taylor rules

In this paper we systematically evaluate how central banks respond to deviations from the inflation target. We present a stylized New Keynesian model in which agents' inflation expectations are sensitive to deviations from the inflation target. To (re-) establish credibility, monetary policy under discretion sets higher interest rates today if average inflation exceeded the target in the past. Moreover, the central bank responds non-linearly to past inflation gaps. This is reflected in an additional term in the central bank's instrument rule, which we refer to as the ”credibility loss.” Augmenting a standard Taylor (1993) rule with the latter term, we provide empirical evidence for the interest rate response for a sample of five inflation targeting (IT) economies. We find, first, that past deviations from IT feed back into the reaction function and that this influence is economically meaningful. Deterioration in credibility (ceteris paribus) forces central bankers to undertake larger interest rate steps. Second, we detect an asymmetric reaction to positive and negative credibility losses, with the latter dominating the former.     

AN EMPIRICAL ANALYSIS OF BANK STANDBY LETTERS OF CREDIT RISK

Bank exposure to off-balance sheet activities in general and Standby Letters of Credit (SLCs) in particular has become a major concern to regulators. The risk-exposure of SLCs has been re-examined by employing option pricing methodologies to calculate implied asset risk from bank equity and flat deposit insurance, and from risk-premia on bank subordinated debt. The results indicate that SLC reduce systematic risk, equity risk, and implied asset risk. It appears that Standby Letters of Credit contribute to the overall diversification of bank's assets.
