Argyro Panaretou, Mark B. Shackleton and Paul A. Taylor, ‘Corporate risk management and hedge accounting’, reported in Panel 3.9 above in relation to the accuracy of analysts’ forecasts, also look at the relation between hedge accounting by mandatory IFRS adopters in the UK and changes in bid-ask spreads. Their sample is restricted to non-financial firms in the FTSE 350.
They find that derivative users reporting under IFRS experience a decrease in information asymmetry ie, a reduction in bid-ask spreads.
