Assessment of Uncertainty in High Frequency Data : The Observed Asymptotic Variance
Mykland, Per A. - 2016
The availability of high frequency financial data has generated a series of estimators based on intra-day data, improving the quality of large areas of financial econometrics. However, estimating the standard error of these estimators is often challenging. The root of the problem is that...

Testing for Jumps in a Discretely Observed Price Process with Endogenous Sampling Times
Li, Yifan; Nolte, Ingmar; Nolte (Lechner), Sandra; Yu, … - 2021
We propose a new nonparametric test to determine whether finite-activity jumps are present in a discretely observed price process. For a univariate Itô semimartingale, we introduce the concept of censored increments for observations recursively sampled at exit times with respect to a symmetric...

Statistical Properties of Forward Libor Rates
Alexander, Carol; Lvov, Dimitri - Henley Business School, University of Reading - 2003
historical forward rates are used to calibrate the lognormal forward rate model - as advocated by Hull and White (1999, 2000), Longstaff, Santa Clara and Schwartz (1999), Rebonato (1999a,b,c), Rebonato and Joshi (2001) and many others - a Libor yield curve needs to be fit to the available data...

Jumps in Equilibrium Prices and Market Microstructure Noise
Lee, Suzanne S. - 2012
Asset prices observed in financial markets combine equilibrium prices and market microstructure noise. In this paper, we study how to tell apart large shifts in equilibrium prices from noise using high frequency data. We propose a new nonparametric test which allows us to asymptotically remove...

Spot variance path estimation and its application to high frequency jump testing
Bos, Charles S.; Janus, Paweł; Koopman, Siem Jan - 2009
This paper considers spot variance path estimation from datasets of intraday high frequency asset prices in the presence of diurnal variance patterns, jumps, leverage effects and microstructure noise. We rely on parametric and nonparametric methods. The estimated spot variance path can be used...
