ABSTRACT Focusing on firm‐size heterogeneity, this study examines how institutional reform reshapes the effects of environmental, social, and governance (ESG) disclosure on firm value. Using 2019–2023 panel data on 1427 Japanese listed firms (before and after the 2022 Tokyo Stock Exchange reorganization and Corporate Governance Code revision), this ...

Asymptotic convergence of genetic algorithms
We study a markovian evolutionary process which encompasses the classical simple genetic algorithm. This process is obtained by randomly perturbing a very simple selection scheme. Using the Freidlin-Wentzell theory, we carry out a precise study of the asymptotic dynamics of the process as the perturbations disappear.

Asymptotic properties of a goodness-of-fit test based on maximum correlations [PDF]
We study the efficiency properties of the goodness-of-fit test based on the Qn statistic introduced in Fortiana and Grané (2003) using the concepts of Bahadur asymptotic relative efficiency and Bahadur asymptotic optimality.

ABSTRACT Environmental performance has become strategically critical as regulators mandate disclosure, investors screen for ESG commitments, and consumers reward sustainable practices. Yet whether environmental performance enhances or constrains corporate innovation capacity remains contested.

ABSTRACT ESG ratings, and in particular environmental scores (E‐scores), are becoming increasingly relevant for financial stability and capital allocation decisions. This paper investigates the relationship between corporate environmental performance and market risk, as measured through value at risk (VaR) and expected shortfall (ES), the key metrics ...

Formalization of Asymptotic Convergence for Stationary Iterative Methods
Solutions to differential equations, which are used to model physical systems, are computed numerically by solving a set of discretized equations. This set of discretized equations is reduced to a large linear system, whose solution is typically found using an iterative solver.

Testing for symmetric error distribution in nonparametric regression models [PDF]
For the problem of testing symmetry of the error distribution in a nonparametric regression model we propose as a test statistic the difference between the two empirical distribution functions of estimated residuals and their counterparts with opposite ...
