This paper considers the relationship between traded volume and volatility. We employ short sales data to discriminate between transactions that close existing long positions and transactions that establish new short positions. We test for, and where appropriate, incorporate non-linearity and...

The Friedman-Ball hypothesis implies a link between the inflation rate and inflation uncertainty. In this paper we employ a new test for the joint null hypothesis of no dependence effects and no asymmetry in the G7 inflation volatility. The results show that higher inflation rates operate...

This paper proposes an asymmetric model within which consumer credit facilitates both consumption smoothing and rational habit modification. The model is applied to US data using a GMM approach. The evidence suggests that new credit can predict short-run changes in consumption and has assisted...

There is widespread evidence that the volatility of stock returns displays an asymmetric response to good and bad news. This article considers the impact of asymmetry on time-varying hedges for financial futures. An asymmetric model that allows forecasts of cash and futures return volatility to...

Using UK equity index data, this paper considers the impact of news on time varying measures of beta, the usual measure of undiversifiable risk. The results suggest that beta depends on two sources of news - news about the market and news about the sector. The asymmetric effect in beta is...
