This paper compares real and nominal foreign exchange volatility effects on exports. Using a flexible lag version of the Goldstein-Khan two-country imperfect substitutes model for bilateral trade, we identify the overall effect into both a timing as well as a size impact. We find that the size...

There has recently been considerable interest in the potential adverse effects associated with excessive uncertainty in energy futures markets. Theoretical models of investment under uncertainty predict that increased uncertainty will tend to induce firms to delay investment. These models are...

The failure of decreases in oil prices to produce expansions that mirror the contractions associated with higher oil prices has been a topic of considerable interest. We investigate for the G-7 one explanation for this feature - the role of uncertainty about oil prices. In particular, we examine...

Volatility modelling is a key issue for the finance industry from an academic and practitioner perspective. This is understandable given the importance that volatility plays in risk management and the development of accurate risk measures in a univariate or multivariate framework. To illustrate,...

Extreme asset price movements appear to be more pronounced recently and have major consequences for an economy's financial stability and monetary policies. This paper investigates the extreme behaviour of equity market returns and quantifies the probabilities of these losses. Taking fourteen...

This paper examines the volatility and covariance dynamics of cash and futures contracts that underlie the Optimal Hedge Ratio (OHR) across different hedging time horizons. We examine whether hedge ratios calculated over a short term hedging horizon can be scaled and successfully applied to...

We test whether firm idiosyncratic risk is priced in a large cross-section of U.K. stocks. A distinguishing feature of our paper is that our tests allow for a conditional relationship between systematic risk (beta) and returns in our tests, i.e., conditional on whether the excess market return...
