This commentary examines the slope of the sovereign bond yield curve before and during the Covid-19 pandemic. The yield curve as a sentiment indicator on the future growth prospects of the euro area is upward sloping, indicating that borrowing money long-term is more expensive than short-term...

In this study we estimate and compare the realized range volatility, a novel efficient volatility estimator computed by summing high-low ranges for intra-day intervals, to the recently popularized realized variance estimator obtained by summing squared intra-day returns. Our results derived from...

Using a novel high-frequency data set, we examine the contribution of Greek trading to the price discovery process of a pair of Cypriot blue-chip, cross-listed stocks during overlapping trading hours. Additionally, we investigate the effects of market fragmentation on the home market's quality,...
