Table 7
Conditional Fama–MacBeth regressions based on rating groups. The table presents the results of Fama–MacBeth regressions for individual bonds sorted into two ratings portfolios over the period 1995–2004. High (low) ratings refer to ratings AA or A (BBB or below). Each month, cross-sectional regressions of bond spreads are carried out on bond characteristics (char) and liquidity and volatility values. For each regression, the first row reports the coefficients as the time-series average of 120 monthly regression slopes and the second row presents t-statistics computed as the ratio of time-series average slope to the standard error of monthly slopes with Newey–West correction. The liquidity index (liq indx) and volatility measure (vol meas) refer to bond liquidity Index 1 and 3-factor daily idiosyncratic volatility respectively.
