Brent and WTI oil prices volatility during major crises and Covid-19

EM Iglesias, D Rivera-Alonso - Journal of Petroleum Science and …, 2022 - Elsevier
We provide novel evidence of two different types of volatility-patterns of oil spot prices that
are generated depending on which is the predominant trigger: a) spikes of volatility (which …

Higher order asymptotic theory when a parameter is on a boundary with an application to GARCH models

EM Iglesias, OB Linton - Econometric Theory, 2007 - cambridge.org
Andrews (1999, Econometrica 67, 1341–1383) derived the first-order asymptotic theory for a
very general class of estimators when a parameter is on a boundary. We derive the second …

Long-term timber contracts in the Southeastern United States: Updating the primer valuation framework

HI Restrepo, B Mei, BP Bullock - Forest Science, 2020 - academic.oup.com
Timberland ownership has drastically changed in the United States since the 1980s, driven
by the divestitures of vertically integrated forest products companies. Having sold their …

Estimation, testing, and finite sample properties of quasi-maximum likelihood estimators in GARCH-M models

EM Iglesias, GDA Phillips - Econometric Reviews, 2012 - Taylor & Francis
We provide three new results concerning quasi-maximum likelihood (QML) estimators in
generalized autoregressive conditional heteroskedastic in mean (GARCH-M) models. We …

Bias of a value-at-risk estimator

Y Bao, A Ullah - Finance Research Letters, 2004 - Elsevier
We develop the analytical second-order bias of a Value-at-Risk estimator based on an
ARCH (1) volatility specification when the parameters are estimated by the method of quasi …

Finite sample theory of QMLE in ARCH models with dynamics in the mean equation

EM Iglesias, GDA Phillips - Journal of Time Series Analysis, 2008 - Wiley Online Library
We provide simulation and theoretical results concerning the finite‐sample theory of quasi‐
maximum‐likelihood estimators in autoregressive conditional heteroskedastic (ARCH) …

Bivariate ARCH models: Finite-sample properties of QML estimators and an application to an LM-type test

EM Iglesias, GDA Phillips - Econometric Theory, 2005 - cambridge.org
This paper provides two main new results: the first shows theoretically that large biases and
variances can arise when the quasi-maximum likelihood (QML) estimation method is …

A class of indirect inference estimators: higher‐order asymptotics and approximate bias correction

S Arvanitis, A Demos - The Econometrics Journal, 2015 - academic.oup.com
In this paper, we define a set of indirect inference estimators based on moment
approximations of the auxiliary estimators. Their introduction is motivated by reasons of …

EM Iglesias, GDA Phillips - 2004 - researchgate.net
In this paper we extend the findings in Linton (1997) and Iglesias and Phillips (2003) by
providing simulation and theoretical results concerning the finite sample theory of maximum …
