Flexible Seasonal Long Memory and Economic Time Series

Ooms, M. - Erasmus University Rotterdam, Econometric Institute - 1995

We discuss specification, frequency domain estimation and application of flexible fractionally integrated seasonal long memory time series models, which allow for 'chi-squared' (seasonal) unit root testing. We suggest periodogram regression and approximate ML estimation. We successfully apply a...

Convergence and Persistence of Left-Right Political Orientations in The Netherlands 1978-1995

Eisinga, R.; Franses, Ph.H.B.F.; Ooms, M. - Erasmus University Rotterdam, Econometric Institute - 1997

-Theory- Two theories about trends in left-right political orientations are juxtaposed: the persistence theory claiming that left-right orientations are highly resistant to change versus the irrelevance theory anticipating a move of mass publics towards the center of the left-right continuum....

Autoregression-Based Estimators for ARFIMA Models

Galbraith, John; Zinde-Walsh, Victoria - Centre Interuniversitaire de Recherche en Analyse des … - 2001

This paper describes a parameter estimation method for both stationary and non-stationary ARFIMA (p,d,q) models, based on autoregressive approximation. We demonstrate consistency of the estimator for -1/2 d 1, and in the stationary case we provide a Normal approximation to the finite-sample...

A nonlinear long memory model for US unemployment

Dijk, D.J.C. van; Franses, Ph.H.B.F.; Paap, R. - Erasmus University Rotterdam, Econometric Institute - 2000

Two important empirical features of monthly US unemployment are that shocks to the series seem rather persistent and that unemployment seems to rise faster in recessions than that it falls during expansions. To jointly capture these features of long memory and nonlinearity, respectively, we put...

Ten Things We Should Know About Time Series

McAleer, M.J.; Oxley, L. - Erasmus University Rotterdam, Econometric Institute - 2010

Time series data affect many aspects of our lives. This paper highlights ten things we should all know about time series, namely: a good working knowledge of econometrics and statistics, an awareness of measurement errors, testing for zero frequency, seasonal and periodic unit roots, analysing...

Option Valuation with Conditional Heteroskedasticity and Non-Normality

Christoffersen, Peter; Elkamhi, Redouane; Feunou, Bruno; … - Centre Interuniversitaire de Recherche en Analyse des … - 2009

We provide results for the valuation of European style contingent claims for a large class of specifications of the underlying asset returns. Our valuation results obtain in a discrete time, infinite state-space setup using the no-arbitrage principle and an equivalent martingale measure. Our...

Short and Long Memory in Equilibrium Interest Rate Dynamics

Duan, Jin-Chuan; Jacobs, Kris - Centre Interuniversitaire de Recherche en Analyse des … - 2001

This paper analyzes a large class of processes for the short-term interest rate that are derived in a discrete-time equilibrium framework. The dynamics of interest rates and yields are driven by the dynamics of the conditional volatility of the state variable. Under appropriate parameter...

The Impact of Sampling Frequency and Volatility Estimators on Change-Point Tests

Andreou, Elena; Ghysels, Eric - Centre Interuniversitaire de Recherche en Analyse des … - 2004

The paper evaluates the performance of several recently proposed change-point tests applied to conditional variance dynamics and conditional distributions of asset returns. These are CUSUM-type tests for beta-mixing processes and EDF-based tests for the residuals of such nonlinear dependent...
