macro factors are still important in fitting bond return volatility; whereas the "variance premium" is critical in … explaining stock return volatility. However, the factor model primarily fails in fitting covariances …

Average idiosyncratic volatility and firm idiosyncratic volatility increase with the number of listed firms.

We ex-plain the relation between … idiosyncratic volatility and the number of listed firms through Schumpeterian creative destruction. We show that Schumpeterian …

This paper explores the effect of equity volatility on corporate bond yields. Panel data for the late 1990's show that … idiosyncratic firm-level volatility can explain as much cross-sectional variation in yields as can credit ratings. This finding …, together with the upward trend in idiosyncratic equity volatility documented by Campbell, Lettau, Malkiel, and Xu (2001), helps …

-of-sample volatility of optimized portfolios from each model. A few factors capture the general covariance structure but adding more … yield similar results. Using a tracking error volatility criterion, larger differences appear, with particularly favorable …

information-based model demonstrates that the correlation of beliefs implied by analyst forecasts leads to return correlations … broadly in line with the data, both in levels and across countries - the correlation between predicted and actual is 0.63. Our … findings have implications for market-wide volatility - the model-implied correlations alone can explain 44% of the cross …

It appears that volatility in equity markets is asymmetric: returns and conditional volatility are negatively … correlated. We provide a unified framework to simultaneously investigate asymmetric volatility at the firm and the market level … empirical evidence on asymmetry to Japanese stocks. Although volatility asymmetry is present and significant at the market and …

It is sometimes argued that an increase in stock market volatility raises required stock returns, and thus lowers stock … for this volatility feedback effect. The resulting model is asymmetric, because volatility feedback amplifies large … for large crashes. The model also implies that volatility feedback is more important when volatility is high. In U …
