Business Strategy and the Environment, EarlyView.ABSTRACT This study examines how digital strategic orientation (DSO) and environmental practices (EP) interact to shape innovation and performance among Chilean SMEs. Using survey data from 271 firms (February–May 2022), we estimate a generalized structured component analysis (GSCA) model that accommodates a nonrecursive relationship between DSO and EP.

New copulas based on general partitions-of-unity and their applications to risk management
Dependence Modeling, 2016 We construct new multivariate copulas on the basis of a generalized infinite partition-of-unity approach. This approach allows, in contrast to finite partition-of-unity copulas, for tail-dependence as well as for asymmetry.

Adaptive Bernstein Copulas and Risk Management
Mathematics, 2020 We present a constructive approach to Bernstein copulas with an admissible discrete skeleton in arbitrary dimensions when the underlying marginal grid sizes are smaller than the number of observations.

Business Strategy and the Environment, EarlyView.ABSTRACT Existing literature indicates that transformational leadership in supply chains is critical to sustainability; however, little is known about how this leadership influences sustainability. The empirical literature has provided minimal focused analysis of transformational supply chain leadership and its effects on sustainability performance ...
