Maximum likelihood estimation for generalized autoregressive score models

Blasques, Francisco; Koopman, Siem Jan; Lucas, André - 2014

We study the strong consistency and asymptotic normality of the maximum likelihood estimator for a class of time series … processes. We formulate primitive conditions for global identification, invertibility, strong consistency, and asymptotic …

Asymptotic properties of the weighted-average least squares (WALS) estimator

De Luca, Giuseppe; Magnus, Jan R.; Peracchi, Franco - 2022

We investigate the asymptotic behavior of the WALS estimator, a model-averaging estimator with attractive finite-sample and computational properties. WALS is closely related to the normal location model, and hence much of the paper concerns the asymptotic behavior of the estimator of the unknown...

Asymptotic and finite sample properties for multivariate rotated GARCH models

Asai, Manabu; Chang, Chia-Lin; McAleer, Michael; … - In: Econometrics : open access journal 9 (2021) 2, pp. 1-21

This paper derives the statistical properties of a two-step approach to estimating multivariate rotated GARCH-BEKK … (2sQML) estimator, this paper shows consistency and asymptotic normality under weak conditions. While second …-order moments are needed for the consistency of the estimated unconditional covariance matrix, the existence of the finite sixth …

How much should we trust differences-in-differences estimates?

Bertrand, Marianne (contributor); Duflo, Esther (contributor) - 2001 - [Elektronische Ressource]

Most Difference-in-Difference (DD) papers rely on many years of data and focus on serially correlated outcomes. Yet almost all these papers ignore the bias in the estimated standard errors that serial correlation introduces. This is especially troubling because the independent variable of...

Bipower-Type Estimation in a Noisy Diffusion Setting

Podolskij, Mark; Vetter, Mathias - 2008

We consider a new class of estimators for volatility functionals in the setting of frequently observed Itô diffusions which are disturbed by i.i.d. noise. These statistics extend the approach of pre-averaging as a general method for the estimation of the integrated volatility in the presence of...

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...

Sargan's Instrumental Variable Estimation and GMM

Arellano, Manuel - 2002

This paper surveys J. D. Sargan's work on instrumental variable estimation and its connections with the generalized method of moments. I first present the modelling context in which Sargan motivated instrumental variable estimation. Then I review the theory of instrumental variable estimation as...
