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 …

Most affine models of the term structure with stochastic volatility (SV) predict that the variance of the short rate is …;unspanned stochastic volatility (USV).quot; Of the models tested, only the A1(4) USV model is found to generate both realistic volatility … estimates and a good cross-sectional fit. Our findings suggests that interest rate volatility cannot be extracted from the cross …

This paper addresses the puzzle of regime-dependent volatility in foreign exchange. We extend the literature in two … induce volatility under flexible rates because they have portfolio-balance effects on price, whereas under fixed rates the …

Recently there has been a great deal of interest in modeling volatility fluctuations. ARCH models, for example, provide … parsimonious approximations to volatility dynamics. Here we provide a selective amount of certain aspects of conditional volatility …

The leverage effect refers to the generally negative correlation between an asset return and its changes of volatility … volatility estimated from high-frequency data. The puzzle lies in the fact that such an intuitively natural estimate yields …

We find that increased disagreement is … associated with higher expected returns, higher return volatility, and larger trading volume. These results imply that there is a … positive risk premium for disagreement in asset prices. We also show that volatility in and of itself does not lead to higher …
