Consistent Fixed-Effects Selection in Ultra-high dimensional Linear Mixed Models with Error-Covariate Endogeneity

, 2020
Recently, applied sciences, including longitudinal and clustered studies in biomedicine require the analysis of ultra-high dimensional linear mixed effects models where we need to select important fixed effect variables from a vast pool of available ...

On the Estimation of Panel Regression Models with Fixed Effects [PDF]

This paper considers estimation of panel data models with fixed effects. First, we will show that a consistent ``unrestricted fixed effects'' estimator does not exist for autoregressive panel data models with initial conditions.

ESG performance as an informational signal: dual effects on the cost of capital and price synchronicity

Cogent Economics & Finance
This study examines how firms’ environmental, social, and governance (ESG) performance jointly affects the cost of capital and stock price synchronicity. Using firm-year data for companies listed on the Stock Exchange of Thailand (2015–2024).

Fixed effects selection in the linear mixed-effects model using adaptive ridge procedure for L0 penalty performance

, 2017
This paper is concerned with the selection of fixed effects along with the estimation of fixed effects, random effects and variance components in the linear mixed-effects model.

Executive Quirks in Operational Decisions [PDF]

We ask if corporate executives have fixed effects (quirks) that explain perational decisions made in firms, independent of firm effects. We replicate the approach in Bertrand et al.

Comparison of different animal models for estimating genetic parameters for early growth traits and reproductive traits in Tianmu Sainuo sheep

Frontiers in Veterinary Science
As the economic level of individuals rises, so too does the demand for mutton. Enhancing the breeds of mutton sheep not only boosts production efficiency and economic benefits but also fosters the sustainable growth of the mutton sheep breeding industry.

Fixed Effects Bias in Panel Data Estimators [PDF]

Since little is known about the degree of bias in estimated fixed effects in panel data models, we run Monte Carlo simulations on a range of different estimators. We find that Anderson-Hsiao IV, Kivietâs bias-corrected LSDV and GMM estimators all perform

The fixed point action for the Schwinger model: a perturbative approach

, 1997
We compute the fixed point action of a properly defined renormalization group transformation for the Schwinger model through an expansion in the gauge field. It is local, with couplings exponentially suppressed with the distance.

A hazard model for welfare durations with unobserved location-specific effects [PDF]

Many papers have investigated how personal characteristics and environmental variables affect welfare durations of unmarried mothers. This paper estimates proportional hazard models for welfare durations that allow for either fixed state or fixed labor ...
