The Asymptotic Properties of the System GMM Estimator in Dynamic Panel Data Models When Both N and T are Large [PDF]
This paper complements Alvarez and Arellano (2003) by showing the asymptotic properties of the system GMM estimator for AR(1) panel data models when both N and T tend to infinity.

ABSTRACT The relationship between eco‐innovation (EI) and firm performance (FP) is central to environmental management research, yet empirical evidence remains fragmented and highly context dependent. This article presents a global systematic literature review (SLR) of 541 empirical studies (2006–April 2025) to (i) diagnose the systematic sources of ...

An Improved Approximation to the Distributions in GMM Estimation [PDF]
The empirical saddlepoint distribution provides an approximation to the sampling distributions for the GMM parameter estimates and the statistics that test the overidentifying restrictions.

ABSTRACT This paper examines how the European Union Emissions Trading System allowance prices reshape the link between corporate environmental performance (CEP) and firms' growth expectations, measured by Tobin's Q. Using a panel of 1370 listed firms across 15 European countries from 2005 to 2024 and high‐dimensional fixed‐effects models, we first ...

GMM Redundancy Results for General Missing Data Problems [PDF]
We consider questions of efficiency and redundancy in the GMM estimation problem in which we have two sets of moment conditions, where two sets of parameters enter into one set of moment conditions, while only one set of parameters enters into the other.

ABSTRACT This study investigates how directors with environmental protection (EP) backgrounds influence corporate biodiversity concern (BIO) among Chinese A‐share listed firms from 2008 to 2023. Drawing on Upper Echelons Theory, we argue that directors' environmental expertise shapes firms' biodiversity strategies.

ABSTRACT The United States (U.S.) faces challenges in achieving its ambitious net‐zero carbon emissions target by 2050, with current emissions having fallen by less than 1% in 2024. Despite an investment of $500 billion in low‐carbon resources while holding the second‐largest green technology patent portfolio globally, it is further imperative to ...

Symmetrically normalized instrumental-variable estimation using panel data. [PDF]
In this paper we discuss the estimation of panel data models with sequential moment restrictions using symmetrically normalized GMM estimators. These estimators are asymptotically equivalent to standard GMM but are invariant to normalization and tend to ...
