We investigate the role of jumps in transmitting volatility between foreign exchange markets (Engle, Ito, and Lin, 1990; Melvin and Peiers Melvin, 2003; Cai, Howorka, and Wongswan, 2008). We show that recently developed estimators have very different implications for the impact of jumps on exchange rate...

This paper studies bivariate tail comovements on financial markets that are of crucial importance for the world economy: The S&P 500, US bonds, and currencies. We propose to study that form of dependence under the lens of cojump identification in a bivariate Brownian semimartingale with...

We use recently proposed tests to extract jumps and cojumps from three types of assets: stock index futures, bond futures, and exchange rates. We then characterize the dynamics of these discontinuities and informally relate them to U.S. macroeconomic releases before using limited dependent...

This article tests the linearity assumption underlying the popular heterogeneous autoregressive model for realized volatility (HAR-RV). We implement a consistent model specification test that is robust to both distributional and model misspecification. We find that, using a nonparametric HAR-RV...
