GMM Estimation of Autoregressive Roots Near Unity with Panel Data [PDF]
This paper investigates a generalized method of moments (GMM) approach to the estimation of autoregressive roots near unity with panel data. The two moment conditions studied are obtained by constructing bias corrections to the score functions under OLS ...

Noise Classification Based on GMM and AANN
, 2011 In this paper, Gaussian Mixture model (GMM) as specific method is applied to noise classification. On this basis, a modified Gaussian Mixture Model with an embedded Auto-Associate Neural Network (AANN) is proposed.

Equidispersion and moment conditions for count panel data model [PDF]
This paper proposes some new moment conditions under the assumption of the equidispersion in count panel data model. These are obtained by using the association between variances and covariances in the disturbance. Some Monte Carlo experiments configured

Critical Materials Import and Environmental Preferences: Evidence From G20 and N11 Economies
Business Strategy and the Environment, EarlyView.ABSTRACT Critical materials such as lithium and cobalt are indispensable for achieving the United Nations' Sustainable Development Goals (SDGs), particularly SDG 7 (Affordable and Clean Energy) and SDG 13 (Climate Action). While these materials enable the deployment of low‐carbon technologies, including electric vehicle batteries and renewable energy ...

Does Climate Risk Affect Employment Decisions? International Evidence
Business Strategy and the Environment, EarlyView.ABSTRACT This study investigates the effect of climate risk on corporate employment decisions. Using a large sample from 41 countries, we find a positive association between climate risk and underinvestment in labor, notably manifesting as excessive employee layoffs.

GMM Estimation of Income Distributions from Grouped Data [PDF]
We develop a GMM procedure for estimating income distributions from grouped data with unknown group bounds. The approach enables us to obtain standard errors for the estimated parameters and functions of the parameters, such as inequality and poverty ...

Business Strategy and the Environment, EarlyView.ABSTRACT Firms increasingly commit to climate targets yet doubts remain about whether such pledges translate into substantive corporate governance or remain symbolic. The study examines how emission reduction targets (ERTs) in sustainability strategies are reflected in compensation among German listed firms.

Identification of the Covariance Structure of Earnings Using the GMM Estimator [PDF]
In this paper we study the performance of the GMM estimator in the context of the covariance structure of earnings. Using analytical and Monte Carlo techniques we examine the sensitivity of parameter identification to key features such as panel length ...
