The slope of the credit yield curve for speculative-grade issuers
Many theoretical bond pricing models predict that the slope of the credit yield curve facing highly leveraged firms is negative. Previous empirical research by Sarig and Warga (1989) and Fons (1994) confirms this view of high yield bonds. We show that these results largely owe to sample selection bias associated with the debt maturity choice. When the credit quality of the issuer is held constant, as in the case of matched bond samples, the typical credit yield curve facing speculative-grade issuers is upward-sloping.
Multiple ratings and credit standards: differences of opinion in the credit rating industry
This paper tests whether the tendency of third rating agencies to assign higher ratings than Moody's and Standard & Poor's results from more lenient standards or sample selection bias. More lenient standards might result from incentives to satisfy issuers who are, in fact, the purchasers of the ratings. Selection bias might be important because issuers that expect a low rating from a third agency are unlikely to request one. Our analysis of a broad sample of corporate bond ratings at year-end 1993 reveals that, although sample selection bias appears important, it explains less than half the ...

Corporate Bond Spreads and the Pandemic III: Variance across Sectors and Firms
Corporate bond spreads widened when COVID-19 initially began spreading, then spreads stabilized. How have spreads fared across individual sectors and issuances from the same firm?
