Testing for Multifractality of Islamic Stock Markets

Saâdaoui, Foued - 2017

Studying the power-law scaling of financial time series is a promising area of econophysics, which has often contributed to the understanding of the intricate features of the global markets. In this article, we examine the multifractality of some financial processes and the underlying formation...

On the short term stability of financial ARCH price processes

Zumbach, Gilles O. - 2021

For many financial applications, it is important to have reliable and tractable models for the behavior of assets and indexes, for example in risk evaluation. A successful approach is based on ARCH processes, which strike the right balance between statistical properties and ease of computation....

Time Series Momentum and Market Stability

He, Xue-zhong - 2014

We propose a continuous-time heterogeneous agent model consisting of fundamental, momentum, and contrarian traders to explain the significant time series momentum. We show that the market under-reacts in short-run and over-reacts in long-run when momentum traders dominate the market, which...

A Bayesian Covariance Graph and Latent Position Model for Multivariate Financial Time Series

Ahelegbey, Daniel Felix - 2020

Current understanding holds that financial contagion is driven mainly by system-wide interconnectedness of institutions. A distinction has been made between systematic and idiosyncratic channels of contagion, with shocks transmitted through the latter expected to be substantially more likely to...

Analysis of Complex Network Convergence Rate to Stationary Distribution via Spectral Approach

Kalimulina, Elmira Yu - 2022

The paper considers the problem of estimating the rate of convergence to the stationary distribution of complex queuing networks. The paper provides an overview of some well-known approaches to solving such problems: functional inequalities, inequalities for the spectral gap, сoupling method...

Kernel Matching Scheme for Block Bootstrap of Time Series Data

Kim, Tae Yoon; Hwang, Sun Young - 2004

aligning these blocks into a bootstrap sample. Recently, several matching schemes for the block bootstraps have been suggested … to improve its performance by reduction of bias [Bernoulli 4 (1998), 305]. The matching schemes are usually achieved by … aligning with higher likelihood those blocks which match at their ends. The kernel matching scheme we consider here takes some …

Estimating Multi-Equational Lqac Models with I(1) Variables : A VAR Approach

Fanelli, Luca - 1998

This paper extends the existing literature on linear quadratic adjustment cost (LQAC) models under rational expectations to the inferential issues arising when: (i) agents optimise with respect to a vector of endogenous variables; (ii) the behavioural equations stemming from the agent's...
