Computationally attractive stability tests for the efficient method of moments
Sluis, Pieter J. van der - 1997
Estimation using simulation techniques may be very time consuming. Specification tests for structuralstability often require more than one of such computationally demanding estimators. Typically one for thesample, one for the post-sample and one for the combination of sample and post-sample is...

Stochastic Volatility : A Tale of Co-Jumps, Non-Normality, GMM and High Frequency Data
Ewald, Christian-Oliver - 2020
In this article we introduce a linear quadratic volatility model with co-jumps and show how to cal- ibrate this model to a rich dataset. We apply GMM and more specifically match the moments of realized power and multi-power variations, which are obtained from high-frequency stock market data....

Modeling Intraday Momentum and Reversal by a Parsimonious Diffusion Process
Ling, Shiqing - 2019
We extend the double-well potential process to a three-parameter version in order to model intraday price dynamics, with a focus on the intraday momentum and reversal. The proposed process has a parsimonious form of three parameters controlling momentum, reversal, and volatility respectively. By...

Detecting serial dependence in tail events
Diks, Cees G. H. - 2002
A test for serial independence is proposed which is related to the BDS test but focuses on tail event probabilities rather than probabilities near the center of the distribution. The motivation behind this approach is to obtain a test more suitable for detecting structure in the tails, such as...

A Revised Trade-to-Trade Model for All Levels of Trading Thinness in Event Studies
Anderson, Warwick W. - 2010
This paper offers an improvement to the trade-to-trade model for event studies. While the trade-to-trade model of Maynes and Rumsey (1993) addresses the problem of thin trading by eliminating periods in which no trading is recorded, the proposed improvement addresses the influence of zero-value...

Modeling Stock Price Movements : Multifractality or Multifractionality?
Bianchi, Sergio - 2011
The scaling properties of two alternative fractal models recently proposed to characterize the dynamics of stock market prices are compared. The former is the Multifractal Model of Asset Return (MMAR) introduced in 1997 by Mandelbrot, Calvet and Fisher in three companion papers. The latter is...

Modelling Co-Movements and Tail Dependency in the International Stock Market Via Copulae
Ignatieva, Katja - 2012
This paper examines international equity market co-movements using time-varying copulae. We examine distributions from the class of Symmetric Generalized Hyperbolic (SGH) distributions for modelling univariate marginals of equity index returns. We show based on the goodness-of-fit testing that...

Subsampling Hypothesis Tests for Nonstationary Panels with Applications to Exchange Rates and Stock Prices
Choi, In; Chue, Timothy K. - 2005
This paper studies subsampling hypothesis tests for panel data that may be nonstationary, cross-sectionally correlated … the tests without estimating nuisance parameters. The tests include panel unit root and cointegration tests as special … shown that subsampling provides asymptotic distributions that are equivalent to the asymptotic distributions of the panel …
