Too Hot to Profit? Climatic Stress and Farm‐Level Performance in Italian Viticulture
ABSTRACT This paper investigates the economic impact of long‐run climatic conditions on Italian wine farms by applying a Ricardian framework to 1431 firms from the 2022 RICA‐FADN survey. We combine farm‐level revenues with viticulture‐specific agroclimatic indicators to assess how climate stress shapes profitability across 77 Italian NUTS3 provinces ...

Internalization of Management Systems and Eco‐Product Innovation: The More the Better?
ABSTRACT Environmental challenges demand urgent and strategic responses from firms. Eco‐product innovation (EPI) is a key approach to reducing environmental impact while preserving competitiveness. This research analyses the relationship between EPI and the internalization of management system (MS) certifications, focusing on ISO 9001, ISO 14001, and ...

Ensemble‐based soil liquefaction assessment: Leveraging CPT data for enhanced predictions
Abstract This study focuses on predicting soil liquefaction, a critical phenomenon that can significantly impact the stability and safety of structures during seismic events. Accurate liquefaction assessment is vital for geotechnical engineering, as it informs the design and mitigation strategies needed to safeguard infrastructure and reduce the risk ...

Abstract We develop a delay‐aware estimation and control framework for a non‐isothermal axial dispersion tubular reactor modelled as a coupled parabolic‐hyperbolic PDE system with recycle‐induced state delay. The infinite‐dimensional dynamics are preserved without spatial discretization by representing the delay as a transport PDE and adopting a late ...

Abstract We establish the consistency and the asymptotic distribution of the least squares estimators of the coefficients of a subset vector autoregressive process with exogenous variables (VARX). Using a martingale central limit theorem, we derive the asymptotic normal distribution of the estimators. Diagnostic checking is discussed using kernel‐based
