The Cross‐Section of Credit Risk Premia and Equity Returns

We explore the link between a firm's stock returns and credit risk using a simple insight from structural models following Merton ( 1974 ): risk premia on equity and credit instruments are related because all claims on assets must earn the same compensation per unit of risk. Consistent with theory, we find that firms' stock returns increase with credit risk premia estimated from CDS spreads. Credit risk premia contain information not captured by physical or risk‐neutral default probabilities alone. This sheds new light on the “distress puzzle”—the lack of a positive relation between equity returns and default probabilities—reported in previous studies.     

Time‐Varying Asset Volatility and the Credit Spread Puzzle

Most extant structural credit risk models underestimate credit spreads—a shortcoming known as the credit spread puzzle. We consider a model with priced stochastic asset risk that is able to fit medium‐ to long‐term spreads. The model, augmented by jumps to help explain short‐term spreads, is estimated on firm‐level data and identifies significant asset variance risk premia. An important feature of the model is the significant time variation in risk premia induced by the uncertainty about asset risk. Various extensions are considered, among them optimal leverage and endogenous default.     

Investment timing and optimal capital structure under liquidity risk

Deterioration in debt market liquidity reduces debt values and affects firms' decisions. Considering such risk, we develop an investment timing model and obtain analytic solutions. We carry out a comprehensive analysis in optimal financing, default, and investment strategies, and stockholder–bondholder conflicts. Our model explains stylized facts and replicates empirical findings in credit spreads. We obtain six new insights for decision makers. We propose a ‘new trade-off theory’ for optimal capital structure, a new tax effect, and new explanations of ‘debt conservatism puzzle’ and ‘zero-leverage puzzle’. Failure in recognizing liquidity risk results in substantially over-leveraging, early bankruptcy or investment, overpriced options, and undervalued coupons and credit spreads. In addition, agency costs are surprisingly small for a high liquidity risk or a low project risk. Interestingly, the risk shifting incentive and debt overhang problem decrease with liquidity risk under moderate tax rates while they increase under high tax rates.     

Investment‐Based Corporate Bond Pricing

A standard assumption of structural models of default is that firms' assets evolve exogenously. In this paper, we examine the importance of accounting for investment options in models of credit risk. In the presence of financing and investment frictions, firm‐level variables that proxy for asset composition are significant determinants of credit spreads beyond leverage and asset volatility, because they capture the systematic risk of firms' assets. Cross‐sectional studies of credit spreads that fail to control for the interdependence of leverage and investment decisions are unlikely to be very informative. Such frictions also give rise to a realistic term structure of credit spreads in a production economy.     

Rollover Risk and Credit Risk

Our model shows that deterioration in debt market liquidity leads to an increase in not only the liquidity premium of corporate bonds but also credit risk. The latter effect originates from firms' debt rollover. When liquidity deterioration causes a firm to suffer losses in rolling over its maturing debt, equity holders bear the losses while maturing debt holders are paid in full. This conflict leads the firm to default at a higher fundamental threshold. Our model demonstrates an intricate interaction between the liquidity premium and default premium and highlights the role of short‐term debt in exacerbating rollover risk.     

Sovereign default risk premia: Evidence from the default swap market

This study explores the risk premia embedded in sovereign default swaps using a term structure model. The risk premia remunerate investors for unexpected changes in the default intensity. A number of interesting results emerge from the analysis. First, the risk premia contribution to spreads decreases over the sample, 2003–07, and rebounds at the start of the ‘credit crunch.’ Second, daily risk premia co-move with US macro variables and corporate default risk. Third, global factors explain most of Latin American countries' premia, and local factors best explain European and Asian premia. The importance of global factors grows over time. Finally, conditioning on lagged local and global variables at a weekly frequency, sovereign risk premia are highly predictable.     

基于担保机制的网络联保融资模式创新

中小企业因经营规模小、管理不完善、信息披露机制不健全等原因使银企之间出现信息不对称,导致商业银行在贷款时出于风险的考虑不愿意向中小企业放款。网络联保贷款为解决中小企业融资难和降低银行贷款风险提供了一条新路径。但在内外部约束不够强烈的条件下,网络联保运行机制会出现失效,企业倾向于选择策略性违约而给银行带来损失。为进一步降低风险,将担保制度引入到网络联保融资模式中,可以有效降低企业策略性违约的概率。     

Firm dynamics and financial development

Using comprehensive firm-level datasets, this paper studies the impact of cross-country variation in financial market development on firms' financing choices and growth. In less financially developed economies, small firms grow faster and have lower leverage than large firms. As financial development improves, the growth difference between small and large firms shrinks, while the leverage difference rises. The paper then develops a quantitative model where financial frictions drive firm growth and debt financing through the availability of credit and default risk. The model explains the observed cross-country variations in firm size, leverage and growth in response to changes in financial frictions.     

Government contracts and trade credit

This study examines the association between government contracts and firms' use of trade credit. Firms with government contracts may demand less trade credit because of their lower operational risk, higher firm performance, stronger capacity to generate internal funds, and better access to other sources of financing. On the other hand, government contractors could receive more trade credit extensions from suppliers. We examine a sample of U.S. listed firms from 2000 to 2016 and find that firms with government contracts have a lower level of trade credit. We also find that government contractors make quicker payments for trade credit contracts than other firms. Moreover, we provide empirical evidence of government contractors' lower levels of operational risk and higher firm performance, which may enable government contractors to generate adequate internal funds for their operations or to obtain other forms of financing at a lower cost and thus lower their demand for trade credit. Incremental to prior research, our study suggests that having government contracts is one of the factors determining trade credit and firms' financing decisions.     

What drives corporate default risk premia? Evidence from the CDS market

This article studies the economic factors behind corporate default risk premia in Europe during the period 2006–2010. We employ information embedded in Credit Default Swap (CDS) contracts to quantify expected excess returns from the underlying bonds in market-wide default circumstances. We disentangle the compensation to investors for unexpected changes in the creditworthiness of the bond issuer from their remuneration for the risk that the bond's price will drop in the event of default. Our results show that the risk premia associated with systematic factors influencing default arrivals represent approximately 40% of total CDS spread (on median). These premia also exhibit a strong source of commonality; a single principal component explains approximately 88% of their joint variability. This factor significantly covaries with aggregate illiquidity and sovereign risk variables. Empirical evidence suggests a public-to-private risk transfer between sovereign credit spread and corporate risk premia. Finally, the compensation in the event of default is approximately 14 basis points of the total CDS spread, and a significant amount of jump-at-default risk may not be diversifiable.     

Does the debt market assess large banks, risk? : Time series evidence from money center CDs

Uninsured bank liabilities should offer a promised yield that compensates depositors for their expected default losses. However, the conjectural, guarantees available to large U.S. banking firms makes it questionable whether large depositors should or do feel themselves exposed to credit risk. Prior papers have evaluated the determinants of bank risk premia using cross-sectional data, with relatively inconclusive results. This paper investigates the same issue in a methodologically independent fashion: using time series data on specific banks' daily offering rates during the period May 1982 through July 1988. We find that CD rates paid by large money center banks include significant default risk premia.     

Assessing the credit worthiness of Italian SMEs and mini-bond issuers

A number of innovations have been introduced in the last five years to counter the devastating impact of credit rationing in Europe, particularly from traditional bank lending. This is a major problem for the small and medium size firms' sector in Europe, which has also suffered from bank regulatory concerns of capital adequacy, heightened emphasis on default risk of bank counterparties and the general malfunctioning of credit extension and private sector growth. In Italy, some of these less traditional sources of funding for SMEs have started to become more popular and the development of the mini-bond market is a clear example. We believe “mini-bonds” can be a success in Italy as long as the market supplies an attractive risk/return tradeoff to investors as well as affordable and flexible financing for borrowers. Assessments of credit risk must be convincing and objective, providing complements to the traditional rating agency process. In this study, we develop a new innovative model to assess SMEs' creditworthiness and we test it on the companies that have issued mini-bonds so far. Our findings confirm that the amount of information asymmetry is still high in the market and is affecting the level of risk/return trade off potentially reducing the number of investors and small businesses that would be interested in using this new channel to fund their business growth.     

Default risk premium and asset prices

We estimate a standard structural model of credit risk to draw insights about the premium demanded by investors for bearing default risk, using data on credit default swaps and market capitalization. We pin down the daily market value of assets for a set of non-financial firms and uncover cross-sectional heterogeneity in terms of the magnitude and time variation of the premium. By exploring the link between asset and default risk premia, we show that this heterogeneity closely depends on the relationship between the firm-specific market value of the assets and the business cycle.     

A Model of Mortgage Default

In this paper, we solve a dynamic model of households' mortgage decisions incorporating labor income, house price, inflation, and interest rate risk. Using a zero‐profit condition for mortgage lenders, we solve for equilibrium mortgage rates given borrower characteristics and optimal decisions. The model quantifies the effects of adjustable versus fixed mortgage rates, loan‐to‐value ratios, and mortgage affordability measures on mortgage premia and default. Mortgage selection by heterogeneous borrowers helps explain the higher default rates on adjustable‐rate mortgages during the recent U.S. housing downturn, and the variation in mortgage premia with the level of interest rates.     

CDOs and the financial crisis: Credit ratings and fair premia

We study risk and return characteristics of CDOs using the market standard models. We find that fair spreads on CDO tranches are much higher than fair spreads on similarly-rated corporate bonds. Our results imply that credit ratings are not sufficient for pricing, which is surprising given their central role in structured finance markets. This illustrates limitations of the rating methodologies that are solely based on real-world default probabilities or expected losses and do not capture risk premia. We also demonstrate that CDO tranches have large exposure to systematic risk and thus their ratings and prices are likely to decline substantially when credit conditions deteriorate.     

Limited arbitrage between equity and credit markets

We document that short-horizon pricing discrepancies across firms' equity and credit markets are common and that an economically significant proportion of these are anomalous, indicating a lack of integration between the two markets. Proposing a statistical measure of market integration, we investigate whether equity–credit market integration is related to impediments to arbitrage. We find that time variation in integration across a firm's equity and credit markets is related to firm-specific impediments to arbitrage such as liquidity in equity and credit markets and idiosyncratic risk. Our evidence provides a potential resolution to the puzzle of why Merton model hedge ratios match empirically observed stock-bond elasticities (Schaefer and Strebulaev, 2008) and yet the model is limited in its ability to explain the integration between equity and credit markets (Collin-Dufresne, Goldstein, and Martin, 2001).     

Municipal Debt and Marginal Tax Rates: Is There a Tax Premium in Asset Prices?

We study the marginal tax rate incorporated into short‐term municipal rates using municipal swap market data. Using an affine model, we identify the marginal tax rate and the credit/liquidity spread in 1‐week tax‐exempt rates, as well as their associated risk premia. The marginal tax rate averages 38.0% and is related to stock, bond, and commodity returns. The tax risk premium is negative, consistent with the strong countercyclical nature of after‐tax fixed‐income cash flows. These results demonstrate that tax risk is a systematic asset pricing factor and help resolve the muni‐bond puzzle.     

Effect of rollover risk on default risk: Evidence from bank financing

We study the effect of rollover risk on the risk of default using a comprehensive database of U.S. industrial firms during 1986–2013. Dependence on bank financing is the key driver of the impact of rollover risk on default risk. Default risk and rollover risk present a significant positive relation in firms dependent on bank financing. In contrast, rollover risk is uncorrelated with default probability in the case of firms that do not rely on bank financing. Our measure of rollover risk is the amount of long-term debt maturing in one year, weighted by total assets. In the case of a firm that depends on bank financing, an increase of one standard deviation in this measure leads to a significant increase of 3.2% in its default probability within one year. Other drivers affecting the interaction between rollover risk and default risk are whether a firm suffers from declining profitability and has poor credit. Additionally, rollover risk's impact on default probability is stronger during periods when credit market conditions are tighter.     

Credit risk dynamics in response to changes in the federal funds target: The implication for firm short-term debt

The recent credit crisis has raised a number of interesting questions regarding the role of the Federal Reserve Bank and the effectiveness of its expected and unexpected interventions in financial markets, especially during the crisis, given its mandate. This paper reviews and evaluates the impact of expected and unexpected changes in the federal funds rate target on credit risk premia. The paper's main innovation is the use of an ACH-VAR (autoregressive conditional hazard VAR) model to generate the Fed's expected and unexpected monetary policy shocks which are then used to determine the effects of a Federal Reserve policy change on counterparty credit risk and more importantly short-term firm debt financing. The findings answer a longstanding question sought by researchers on the effect of policy makers' announcements on firm debt financing. The results clearly show that the Federal Reserve influences short-term debt financing through the credit channel for both expansionary and contractionary monetary policies. In particular, we find that the growth in counterparty risk appears less responsive to anticipated responses in the Fed funds rate that fail to materialize than to an unanticipated increase in the federal funds rate. Finally, we also document that the results appear to validate the Feds interventions in financial markets to stem counterparty risk and to make liquidity more readily available to firms.     

Firms' Off-Balance Sheet and Hybrid Debt Financing: Evidence from Their Book-Tax Reporting Differences

We match large U.S. corporations' tax returns during 1989–2001 to their financial statements to construct a firm‐level proxy of firms' use of off‐balance sheet and hybrid debt financing. We find that firms with less favorable prior‐period Standard & Poor's (S&P) bond ratings or higher leverage ratios in comparison to their industry report greater amounts of interest expense on their tax returns than to investors and creditors on their financial statements. These between‐firm results are consistent with credit‐constrained firms using more structured financing arrangements. Our within‐firm tests also suggest that firms use more structured financing arrangements when they enter into contractual loan agreements that provide incentives to manage debt ratings. Specifically, we find that after controlling for S&P bond rating and industry‐adjusted leverage, our sample firms report greater amounts of interest expenses for tax than for financial statement purposes when they enter into performance pricing contracts that use senior debt rating covenants to set interest rates. Furthermore, we find that the greatest book‐tax reporting changes occur when firms become closer to violating these debt rating covenants. These latter findings are consistent with firms' contractual debt covenants influencing their use of off‐balance sheet and hybrid debt financing.
