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.     

Top management turnover,firm performance and government control: Evidence from China's listed state-owned enterprises

Using a sample of 916 Chinese listed state-owned enterprises (SOEs) from 2001 to 2005, we find that the likelihood of top management turnover is negatively associated with firm performance, suggesting the existence of an effective corporate governance mechanism in an emerging economy that is highly controlled by government. We also find that the negative turnover–performance relationship is stronger when the SOE is directly held by the central or local government, holding a monopolistic position in a local economy or in a strategic/regulated industry. The results indicate that the market-based corporate governance mechanism that disciplines top executives as a result of poor performance is not only used in Chinese SOEs, but is used more frequently when the governance control of SOEs is more intense. Our findings support the notion that government control strengthens rather than weakens the turnover–performance governance mechanism. Our additional analysis shows that this complementary effect is stronger in regions that lack pro-market institutions, such as investor protections and a functioning capital market.     

Top management abnormal turnover and stock price crash risk: Evidence from China

The activities and decisions of the top management have garnered considerable attention. The general phenomenon of management turnover has gradually become the focus of investors in capital market, especially top management abnormal turnover. This paper examines the correlation between top management abnormal turnover and stock price crash risk. The research finds that the higher the abnormal turnover rate of top management, the greater the risk of stock price crashes, indicating that top management abnormal turnover can exacerbate the stock price crash risk. Considering that directors' and officers' liability insurance is an instrument for enterprises to protect their own interests, this paper finds D&O insurance can mitigate the stock price crash risk caused by top management abnormal turnover. Based on China's special national conditions, further researches also consider political associations and the nature of property right. The results advance our understanding of top management abnormal turnover and directors' and officers' liability insurance, and remind companies to reduce stock price crash risk when the top management leaves.     

Tournament incentives and firm credit risk: Evidence from credit default swap referenced firms

In this paper, we evaluate the impact of managerial tournament incentives on firm credit risk in credit default swap (CDS) referenced firms. We find that intra‐firm tournament incentives are negatively related to credit risk. Our results suggest that tournament incentives reduce credit risk by alleviating the potential for underinvestment when managers are concerned about exacting empty creditors. Further, we find that tournament incentives decrease credit risk when internal governance is strong or product market competition is intense. Taken together, our results suggest that creditors perceive senior manager tournament incentives (SMTI) as a critical determinant of a firm's credit risk, particularly in settings where managerial risk aversion is high.     

Corporate risk management and firm value: evidence from the UK market

The paper evaluates the effect of corporate risk management activities on firm value, using a sample of large UK non-financial firms. Following recent changes in financial reporting standards, we are able to collect detailed information on risk management activities from audited financial reports. This enables us to gain a better understanding of risk management practices and to investigate value implications of different types of hedging. Overall 86.88% of the firms in the sample use derivatives to manage at least one type of price risk. The hedging premium is statistically and economically significant for foreign currency derivative users, while we provide weak evidence that interest rate hedging increases firm value. The extent of hedging and the hedging horizon have an impact on the hedging premium, whereas operational risk management activities do not significantly influence the market value of the firm.     

Single-stock futures: Evidence from the Indian securities market

Although single-stock futures (SSFs) are useful multi-purpose stock derivatives, they have not received much attention in developed markets. We analyze SSFs in the Indian market to understand their contribution in price leadership. The findings indicate that trades in the stock market contribute more to price discovery than trades in the SSF market (72% and 28%, respectively), while quotes in the SSF market are more price innovative than quotes in the stock market (39% and 61%, respectively). Our analysis suggests that while stock and SSF trade returns have predictive ability for each other, in the case of quotes, only SSF quotes have predictive ability for stock and SSF returns.     

Federal financial guarantees and the occasional market pricing of default risk: Evidence from insured deposits

This paper develops a two-date state preference model which demonstrates that investors' valuation of third-party guaranteed debt depends on the financial condition of the guarantor. As the solvency ratio of the guarantor declines, investors demand higher promised rates on the firm's debt securities and price the firm risk variables more sensitively.The empirical results are derived from sample data of FSLIC guaranteed obligations from the late 1980s. Evidence shows differences in the market's perception of FSLlC's insolvency between 1987 and 1988. The market response to a decline in the financial condition of the guarantor affected the value of insured CDs, raising CD rates in relation to the Treasury curve and firm risk pricing of insured deposits emerged.     

Market liquidity risk factor and financial market anomalies: Evidence from the Chinese stock market

The Chinese stock market is an order-driven market and hence its characteristics are structurally different from quote-driven markets. There are no studies that consider the role of the market liquidity risk factor in determining cross-sectional stock returns in a model including financial market anomalies for order-driven markets. Our aim is to test whether financial market anomalies such as firm size, the book-to-market ratio, the turnover rate, and momentum both with and without the inclusion of the market liquidity risk factor in the case of the Chinese stock market can explain cross-sectional stock returns. The empirical framework is based on the model proposed by Avramov and Chordia (AC, 2006). Our main finding is that the AC model can capture financial market anomalies except momentum when we include the market liquidity risk factor on the Chinese stock market.     

Investor protection and the liquidity of cross-listed securities: Evidence from the ADR market

Using ‘American depository receipt’ (ADR) data on various countries, this paper sets out to investigate the relationship between investor protection and firm liquidity. Since weak investor protection leads to greater expropriation by managers, and thus greater asymmetric information costs, liquidity providers will incur relatively higher costs and will therefore offer higher bid–ask spreads. The empirical results demonstrate that the liquidity costs of poor investor protection were more significant during the period of the Asian financial crisis when the expected agency costs were particularly severe. This issue is further analyzed by investigating whether there is any evidence of increases in the vulnerability of ADRs of firms operating in countries with relatively poor investor protection mechanisms during periods of financial crisis.     

Stock pledging and firm risk: Evidence from India

Pledging of personally held common stock is widespread in India, where pledging often serves as lender collateral for large shareholder and promoter personal debt acquisitions. This practice is exacerbated by high ownership concentrations in India, as promoters, often firm founders, control, on average, 51% of their firms’ equity. We examine promoter stock pledging impacts on stock volatility, capital investment decisions, and firm performance, using a sample of 1,452 Indian firms. We find that pledging relatively large proportions of outstanding shares and substantial proportions of shares held by promoters exacerbates stock volatility, fosters lower risk capital investments, adversely affects firm values, and impedes longer‐term performance.     

Timing the investment grade securities market: Evidence from high quality bond funds

We examine the ability of bond fund managers to shift assets between bonds and cash and across bonds of different maturities in order to capture the changes in their relative returns. As measured by estimated changes in portfolio allocations, we find strong evidence of perverse market timing ability between cash and investment grade securities, and our results indicate additional perverse timing across the bond maturity spectrum. Results are robust to an alternative performance metric. We present evidence that the survival of the majority of these funds despite their negative performance may reflect the value investors place on the portfolio diversification benefits of holding these funds.     

The (non-) effect of labor unionization on firm risk: Evidence from the options market

Labor unionization has no causal effect on firm risk. Using a regression discontinuity design to study the impact of labor union elections on option-implied firm risk, we find that unionization per se does not affect investor perceptions about firm price, tail, or variance risk. This finding is robust to studying very short (5-trading day) and long (up to 2-year) windows around the elections. Moreover, there is no unionization effect on firm risk either in subsets of firms facing strong union bargaining power, or with characteristics that prior literature identifies as important determinants of the effect of unionization on firm outcomes.     

Managerial effect or firm effect: Evidence from the private debt market

This paper provides evidence that the managerial effect is a key determinant of firms’ cost of capital, in the context of private debt contracting. Applying the novel empirical method developed by an earlier study to a large sample that tracks the job movement of top managers, we find that the managerial effect is a critical and significant factor that explains a large part of the variation in loan contract terms more accurately than firm fixed effects. Additional evidence shows that banks “follow” managers when they change jobs and offer loan contracts with preferential terms to their new firms.     

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.     

Underwriter reputation and the pricing of securities: Evidence from asset-backed securities

This paper investigates whether and how the underwriter reputation can affect the pricing of securities. Using data on collateralized loan obligations (CLO), asset-backed securities (ABS), and asset-backed medium-term notes (ABN) from 2014 to 2019 in China bond market, we find that the underwriter's reputation has a significantly negative impact on the issuance spread. This effect is more pronounced in the CLO and ABS markets, while that in the ABN market is not significant. Furthermore, we find that the originators play a critical role in determining the issuance spread of securities, as state-owned and listed originator receive a lower initial yield spread. In addition, the number of tranches and the proportion of subordination in a deal also have a stronger effect on the relation between which the underwriters' reputation and securities prices. These results suggest that underwriters play a role in reducing information asymmetry between originators and investors, which is partly corrected via underwriter reputation.     

The impact of central clearing on counterparty risk,liquidity, and trading: Evidence from the credit default swap market

This paper examines the impact of central clearing on the credit default swap (CDS) market using a sample of voluntarily cleared single-name contracts. Consistent with central clearing reducing counterparty risk, CDS spreads increase around the commencement of central clearing and are lower than settlement spreads published by the central clearinghouse. Furthermore, the relation between CDS spreads and dealer credit risk weakens after central clearing begins, suggesting a lowering of systemic risk. These findings are robust to controls for frictions in both CDS and bond markets. Finally, matched sample analysis reveals that the increased post-trade transparency following central clearing is associated with an improvement in liquidity and trading activity.     

Corporate social responsibility and litigation risk: Evidence from securities class action lawsuits

This study examines whether corporate social responsibility (CSR) is associated with the likelihood and outcomes of securities class action lawsuits. We find a lower likelihood of securities litigation for firms with higher CSR. This effect is larger for companies with lower levels of financial distress, companies with larger proportions of institutional investors, and for internal CSR. Additionally, CSR has a mitigating effect on negative market assessments around the filing dates of securities litigation. The results suggest that higher CSR firms are less likely to engage in financial misconduct, and investors are less likely to penalise them for such occurrences.     

Counterparty credit risk and the credit default swap market

Counterparty credit risk has become one of the highest-profile risks facing participants in the financial markets. Despite this, relatively little is known about how counterparty credit risk is actually priced. We examine this issue using an extensive proprietary data set of contemporaneous CDS transaction prices and quotes by 14 different CDS dealers selling credit protection on the same underlying firm. This unique cross-sectional data set allows us to identify directly how dealers' credit risk affects the prices of these controversial credit derivatives. We find that counterparty credit risk is priced in the CDS market. The magnitude of the effect, however, is vanishingly small and is consistent with a market structure in which participants require collateralization of swap liabilities by counterparties.     

Does operating risk affect portfolio risk? Evidence from insurers' securities holding

This study empirically examines, in the setting of insurance companies, the hypothesis that investors facing more operating risk may behave as if they were more risk averse in investment decisions. Specifically, we study how operating risk from underwriting insurance policies affects insurers' risk taking behavior in their portfolio investments. We find that insurers with higher volatilities in underwriting incomes and cash flows are more conservative in their financial investment risk taking – they have lower credit risk exposure in their bond investments, as well as lower portfolio weights on risky bonds and equities. Further, insurers' portfolio risk exposure is sensitive to the risk of permanent underwriting income shocks but insensitive to the risk of transitory shocks. Transitory operating risk, however, is significantly related to portfolio risk when insurers face tight financing constraints. Our findings suggest a substitutive effect of operating risk on investment decisions by financial institutions.     

Estimating a covariance matrix for market risk management and the case of credit default swaps

We analyze covariance matrix estimation from the perspective of market risk management, where the goal is to obtain accurate estimates of portfolio risk across essentially all portfolios—even those with small standard deviations. We propose a simple but effective visualisation tool to assess bias across a wide range of portfolios. We employ a portfolio perspective to determine covariance matrix loss functions particularly suitable for market risk management. Proper regularisation of the covariance matrix estimate significantly improves performance. These methods are applied to credit default swaps, for which covariance matrices are used to set portfolio margin requirements for central clearing. Among the methods we test, the graphical lasso estimator performs particularly well. The graphical lasso and a hierarchical clustering estimator also yield economically meaningful representations of market structure through a graphical model and a hierarchy, respectively.
