Variance Matrix Priors for Dirichlet Process Mixture Models With Gaussian Kernels

International Statistical Review, EarlyView.
Summary Bayesian mixture modelling is widely used for density estimation and clustering. The Dirichlet process mixture model (DPMM) is the most popular Bayesian non‐parametric mixture modelling approach. In this manuscript, we study the choice of prior for the variance or precision matrix when Gaussian kernels are adopted.

A Comparative Review of Specification Tests for Diffusion Models

International Statistical Review, EarlyView.
Summary Diffusion models play an essential role in modelling continuous‐time stochastic processes in the financial field. Therefore, several proposals have been developed in the last decades to test the specification of stochastic differential equations.

Exemption and work environment

Industrial Relations: A Journal of Economy and Society, EarlyView.
Abstract The Labor Standards Act of Japan requires employers to compensate employees based on hours worked, but exemptions apply to specific occupations with agreements between employers and employees. We assess the impact of being exempted on hours worked, earnings, and the physical and mental health conditions of employees.

Evaluating ESG effects on firm's technical efficiency with robust nonparametric frontiers: Insights from Asia

International Transactions in Operational Research, EarlyView.
Abstract This study examines how environmental, social, and governance practices impact firms' technical efficiency, focusing on operational capabilities often overlooked in financial performance measures. Using a nonparametric frontier analysis with robust order‐m estimators, we analyzed 6033 firms across Asia from 2015 to 2022.

Causal allocation of fixed impacts in product systems: Assessing the effect of data demand on network energy consumption

Journal of Industrial Ecology, EarlyView.
Abstract Environmental assessments of digital services currently apply an accounting perspective, and for telecommunication networks (TN) allocate electrical energy consumption in proportion to data traffic. Yet, the power draw by wired TN infrastructure is almost independent of the volume of data traffic flowing through it. Previous assessments of the

Regulatory Capital Management to Exceed Thresholds

Journal of Money, Credit and Banking, EarlyView.
Abstract We investigate whether a carrot approach, which provides benefits for regulatory compliance rather than penalties for noncompliance, incentivizes banks to reach capital levels above the minimum requirements. We document a significant discontinuity at the 10% regulatory capital threshold, where banks receive benefits for exceeding it.

A Systematic Literature Review on Auction Mechanisms: Insights From the Last Decade and Future Directions

Journal of Economic Surveys, EarlyView.
ABSTRACT This study reports the results of a systematic literature review on auctions mechanism. Auctions are a very popular practice employed in many fields but does not exist a research that investigates the use of auctions under a cross‐disciplinary approach. This work is focused on analyzing which are the areas where auctions are mostly adopted and
