Q2. What are the three major filtering criteria used to remove potential measurement errors?
8Three major filtering criteria are adopted to remove potential measurement errors: (1) an outlier criterion that removes quotes that are far above or below the average prices reported by other contributors; (2) a staleness criterion that removes contributed quotes that do not change for a very long period; and (3) a term structure criterion that removes flat curves from the dataset.
Q3. How much of the variance is accounted for by the jump component?
In those days when significant jumps have been detected, the jump component contributes to 52.3% of the total realized variance on average (the range is around 40-80% across the 307 entities).
Q4. What are the main criteria used to remove the spreads?
In addition, the authors also remove those CDS spreads that are higher than 20%, because they are often associated with absence of trading or a bilateral arrangement of an upfront payment.
Q5. Why do the authors eliminate the subordinated class of contracts?
The authors eliminate the subordinated class of contracts because of their small relevance in the database and unappealing implication in credit risk pricing.
Q6. What are the explanatory variables for the CDS spread?
Their explanatory variables include their measures of individual equity volatilities and jumps, rating information, and other standard structural factors including firm-specific balance sheet information and macro-financial variables.
Q7. What are the common variables used to measure the volatility of a firm?
Following the prevalent practice in the existing literature, their firm-specific variables include the firm leverage ratio, return on equity (ROE), and dividend payout ratio.
Q8. What are the advantages of CDS spreads?
Blanco et al. (2005) and Zhu (2004) show that, while CDS and bond spreads are quite in line with each other in the long run, in the short run CDS spreads tend to respond more quickly to changes in credit conditions.
Q9. What are the two assumptions the authors have used in the identification process?
The infrequent occurrence and relative importance of the jump component validate the two assumptions the authors have used in the identification process.
Q10. What are the four variables used to proxy for the overall state of the economy?
And to proxy for the overall state of the economy, the authors use four macro-financial variables: the S&P 500 average daily return and its volatility in the past 6 months, and the average 3-month Treasury rate and the slope of the yield curve in the previous month.
Q11. What is the main reason why CDSs lead the bond market in price discovery?
The fact that CDSs lead the bond market in price discovery is instrumental for their improved explanation of the temporal changes in credit spread by default risk factors.
Q12. How does the R-square increase after controlling for credit ratings?
After controlling for credit ratings, macro-financial variables, and firms’ accounting information, the signs and significance of jump and volatility impacts remain solid, and the R-square increases to 77%.
Q13. What is the average daily return volatility?
The average daily return volatility (annualized) is between 40-50%, independent of whether historical or realized measures are used.
