The Role of Institutional Pressures in Technology Adoption for Low‐Carbon Manufacturing

Business Strategy and the Environment, EarlyView.
ABSTRACT Existing research highlights that the adoption of low‐carbon technologies in manufacturing operations is shaped by the external environment. However, limited understanding exists regarding how technology‐related uncertainty interacts with institutional pressures to influence firms' adoption strategies.

Strong Approximation of Empirical Copula Processes by Gaussian Processes

, 2011
We provide the strong approximation of empirical copula processes by a Gaussian process. In addition we establish a strong approximation of the smoothed empirical copula processes and a law of iterated ...

Orchestrating Ecosystem Resources for Sustainability: Coopetition, Digital Transformation, and Disruptive Sustainable Innovation

Business Strategy and the Environment, EarlyView.
ABSTRACT As sustainability transitions accelerate, firms increasingly engage in innovation ecosystems to pursue disruptive sustainable innovation (DSI). Nevertheless, empirical understanding regarding how innovation ecosystem coopetition—simultaneous cooperation and competition among interdependent actors—translates into sustainability‐oriented ...

ESTIMASI NILAI CONDITIONAL VALUE AT RISK (CVaR) PORTOFOLIO MENGGUNAKAN METODE EVT-GJR-VINE COPULA

E-Jurnal Matematika, 2019
Conditional value at risk (CVaR) is widely used in risk measure that takes into account losses exceeding the value at risk level. The aim of this research is to compare the performance of the EVT-GJR-vine copula method and EVT-GARCH-vine copula method in

Final solution to the problem of relating a true copula to an imprecise copula

, 2019
In this paper we solve in the negative the problem proposed in this journal (I. Montes et al., Sklar's theorem in an imprecise setting, Fuzzy Sets and Systems, 278 (2015), 48-66) whether an order interval defined by an imprecise copula contains a copula.

Hidden Markov graphical models with state‐dependent generalized hyperbolic distributions

Canadian Journal of Statistics, EarlyView.
Abstract In this article, we develop a novel hidden Markov graphical model to investigate time‐varying interconnectedness between different financial markets. To identify conditional correlation structures under varying market conditions and accommodate shape features embedded in financial time series, we rely upon the generalized hyperbolic family of ...

Digital Dynamic Capabilities and Environmental Sustainability: The Role of Circular Supply Chain Practices

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study explores how digital dynamic capabilities (DDC)—specifically digital absorptive capacity (DAC) and digital transformation capacity (DTC)—contribute to environmental sustainability (ES), both directly and through circular supply chain practices (CSCP).
