Reputation,Information, and Herding in Credit Ratings: Evidence from CMBS

The Journal of Real Estate Finance and Economics - We find strong evidence of herding behavior among credit rating agencies (CRAs) in the CMBS market. CRAs are more likely to change their rating if...     

Unexpected Inflation,Capital Structure,and Real Risk‐adjusted Firm Performance

Managers can improve real risk‐adjusted firm performance by matching nominal assets with nominal liabilities, thereby reducing the sensitivity of real risk‐adjusted returns to unexpected inflation. The net asset value of US equity real estate investment trusts (REITs) serves as a good proxy for nominal assets and, accordingly, we use a sample of US REITs to test our hypothesis. We find that for the firms in our sample: (i) their real risk‐adjusted performance, and (ii) their inflation‐hedging qualities are inversely related to deviations from this ‘matching‐nominals’ argument. In addition to providing managers with a vehicle to maximize real risk‐adjusted performance, our findings also provide investors with the tools to infer inflation‐hedging qualities of equity investments.     

贷款证券化、监管资本套利与资本监管改进

巴塞尔协议的资本充足率指标可以反映银行部门吸收风险损失的能力,但是无法监测和控制银行体系外的贷款总额和累积的信用风险。20世纪70年代的贷款证券化创新导致银行进行监管资本套利,并使得资本充足率监管趋于失效。本文基于贷款证券化下银行贷款余额与社会贷款余额的差异,分析银行监管资本套利的微观机制并提出改进资本监管的建议。     

A New Model of Inflation,Trend Inflation,and Long‐Run Inflation Expectations

This paper develops a bivariate model of inflation and a survey‐based long‐run forecast of inflation that allows for the estimation of the link between trend inflation and the long‐run forecast. Thus, our model allows for the possibilities that long‐run forecasts taken from surveys can be equated with trend inflation, that the two are completely unrelated, or anything in between. Using a variety of inflation measures and survey‐based forecasts for several countries, we find that long‐run forecasts can provide substantial help in refining estimates and fitting and forecasting inflation. It is less helpful to simply equate trend inflation with the long‐run forecasts.     

Credit Ratings and Capital Structure

This paper examines to what extent credit ratings directly affect capital structure decisions. The paper outlines discrete costs (benefits) associated with firm credit rating level differences and tests whether concerns for these costs (benefits) directly affect debt and equity financing decisions. Firms near a credit rating upgrade or downgrade issue less debt relative to equity than firms not near a change in rating. This behavior is consistent with discrete costs (benefits) of rating changes but is not explained by traditional capital structure theories. The results persist within previous empirical tests of the pecking order and tradeoff capital structure theories.     

Capital Gains, Dividend Yields, and Expected Inflation

One explanation for the negative relationship between short-horizon stock returns and inflation is that inflation proxies (inversely) for expected future real output. In this paper, I examine the possibility that inflation also proxies for variation in real price/dividend ratios (excess returns). I show that when the covariance between real price/dividend ratios and inflation is nonzero, the relationship between returns and expected inflation differs for the two components of returns: dividend yields and capital gains returns. My empirical evidence demonstrates that dividend yields and capital gains are related differently to expected inflation in U.S. and foreign markets.     

Liquidity Risk and the Dynamics of Arbitrage Capital

We develop a continuous‐time model of liquidity provision in which hedgers can trade multiple risky assets with arbitrageurs. Arbitrageurs have constant relative risk‐aversion (CRRA) utility, while hedgers' asset demand is independent of wealth. An increase in hedgers' risk aversion can make arbitrageurs endogenously more risk‐averse. Because arbitrageurs generate endogenous risk, an increase in their wealth or a reduction in their CRRA coefficient can raise risk premia despite Sharpe ratios declining. Arbitrageur wealth is a priced risk factor because assets held by arbitrageurs offer high expected returns but suffer the most when wealth drops. Aggregate illiquidity, which declines in wealth, captures that factor.     

Regulatory Arbitrage and Cross‐Border Bank Acquisitions

We study how differences in bank regulation influence cross‐border bank acquisition flows and share price reactions to cross‐border deal announcements. Using a sample of 7,297 domestic and 916 majority cross‐border deals announced between 1995 and 2012, we find evidence of a form of “regulatory arbitrage” whereby acquisition flows involve acquirers from countries with stronger regulations than their targets. Target and aggregate abnormal returns around deal announcements are positive and larger when acquirers come from more restrictive bank regulatory environments. We interpret this evidence as more consistent with a benign form of regulatory arbitrage than a potentially destructive one.     

Cross‐Listed Bonds,Information Asymmetry,and Conservatism in Credit Ratings

We propose information asymmetry as an additional explanation for rating conservatism. Because information asymmetry is likely higher for cross‐listed bonds than for U.S. bonds, we expect and find that cross‐listed bonds are rated more conservatively than U.S. domestic bonds at issuance. Further, cross‐listed bonds receive less frequent upgrades and take longer to be upgraded after issuance. Because lower ratings might also reflect higher default risk based on agencies’ private information, we conduct additional tests to discriminate between the rating conservatism and private information explanations. The results are consistent with ratings conservatism and inconsistent with the private information explanation.     

Does Regulatory Capital Arbitrage, Reputation, or Asymmetric Information Drive Securitization?

Banks can choose to keep loans on balance sheet as private debt or transform them into public debt via asset securitization. Securitization transfers credit and interest rate risk, increases liquidity, augments fee income, and improves capital ratios. Yet many lenders still retain a portion of their loans in portfolio. Do lenders exploit asymmetric information to sell riskier loans into the public markets or retain riskier loans in portfolio? If riskier loans are indeed retained in portfolio, is this motivated by regulatory capital incentives (regulatory capital arbitrage), or a concern for reputation? We examine these questions empirically and find that securitized mortgage loans have experienced lower ex-post defaults than those retained in portfolio, providing evidence consistent with either the capital arbitrage or reputation explanation for securitization.

On the Asymmetric U‐Shaped Relationship between Inflation,Inflation Uncertainty,and Relative Price Skewness in the UK

We investigate the asymmetric relationships between aggregate inflation and the second and third moments of the cross‐sectional distribution of relative prices using a modified Calvo pricing model with regime‐dependent price rigidities. Calibration experiments reveal that the inflation‐standard deviation and inflation‐skewness relationships exhibit U‐shaped asymmetries around the historical mean inflation rate. UK sectoral data support our results. We conclude that monetary policy should target an inflation rate proximate to the (common) minima of these nonlinear relationships and that core inflation measures should not be used for policy purposes as they exclude much of the information contained in the higher moments.     

The Allocation of Capital Between Residential and Nonresidential Uses: Taxes,Inflation and Capital Market Constraints

We have constructed a simple two-sector model of the demand for housing and corporate capital. Economic growth and an increase in the inflation rate were then simulated with a number of model variants. The model and simulation experiments illustrate both the tax bias in favor of housing and the manner in which the increase in inflation between 1965 and 1978 magnified it. The existence of capital-market constraints offsets the bias against corporate capital, but it introduces a sharp, inefficient reallocation of housing from less wealthy, constrained households to wealthy households who do not have gains on mortgages and are not financially constrained.     

Inflation and Capital Budgeting Decisions: a Comment

F. M. Wilkes has argued that unadjusted cash flows and monetary opportunity costs be used when evaluating capital projects in an inflationary environment (Journal of Business Finance, Volume 4, No. 3). His conclusions are, however, that alternative approaches to net present value are probably necessary, This note examines Wilkes' analysis and argues that his initial model, using net present value techniques, is acceptable in practice on the adoption of fairly conventional assumptions.     

Idiosyncratic Volatility and Firm‐Specific News: Beyond Limited Arbitrage

We examine the relation between idiosyncratic volatility and returns around news announcements. Mispricing is most likely to occur during news announcements. If idiosyncratic volatility generates a limit to arbitrage, then the negative relation between returns and news volatility should be stronger than the relation to nonnews volatility. Instead, we find nonnews volatility has a robust negative relation to returns and lacks key features expected if volatility were a reflection of limits to arbitrage. Pricing of nonnews volatility is related to lottery‐like features of a stock's return. Our results suggest that volatility has a price effect beyond a limit to arbitrage.     

Asymmetric information,adverse selection,and the pricing of CMBS

We demonstrate that asymmetric information between sellers (loan originators) and purchasers (investors and securities issuers) of commercial mortgages gives rise to a standard lemons problem, whereby portfolio lenders use private information to liquidate lower quality loans in commercial mortgage-backed securities (CMBS) markets. Conduit lenders, who originate loans for direct sale into securitization markets, mitigate problems of asymmetric information and adverse selection in loan sales. Our theory provides an explanation for the pricing puzzle observed in CMBS markets, whereby conduit CMBS loans are priced higher than portfolio loans, despite widespread belief that conduit loans are originated at lower quality. Consistent with theoretical predictions of a lemons discount, our empirical analysis of 141 CMBS deals and 16,760 CMBS loans shows that, after controlling for observable determinants of loan pricing, conduit loans enjoyed a 34 basis points pricing advantage over portfolio loans in the CMBS market.     

The Happiness Trade‐Off between Unemployment and Inflation

Unemployment and inflation lower well‐being. The macroeconomist Arthur Okun characterized the negative effects of unemployment and inflation by the misery index—the sum of the unemployment and inflation rates. This paper makes use of a large European data set, covering the period 1975–2013, to estimate happiness equations in which an individual subjective measure of life satisfaction is regressed against unemployment and inflation rate (controlling for personal characteristics, country, and year fixed effects). We find, conventionally, that both higher unemployment and higher inflation lower well‐being. We also discover that unemployment depresses well‐being more than inflation. We characterize this well‐being trade‐off between unemployment and inflation using what we describe as the misery ratio. Our estimates with European data imply that a 1 percentage point increase in the unemployment rate lowers well‐being by more than five times as much as a 1 percentage point increase in the inflation rate.
