“…The importance of issue size, bond ratings, and various indenture provisions in determining bond yields and underwriter spreads is well documented in the literature (e.g., Allen, Lamy, Thompson (1990), Ederington (1975), Fisher (1959), Livingston, Pratt, and Mann (1995), Mitchell (1991), Sorensen (1979)). Issue duration and convexity are hypothesized to influence Treasury spreads and underwriter spreads; therefore, they are included in the specification as control variables.…”
