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.

Electronic Journal of Statistics, 2014 We propose notions of calibration for probabilistic forecasts of general multivariate quantities. Probabilistic copula calibration is a natural analogue of probabilistic calibration in the univariate setting. It can be assessed empirically by checking for the uniformity of the copula probability integral transform (CopPIT), which is invariant under ...

Toward a Greener Future: How and When Blockchain and Digitization Drive Green Finance
Business Strategy and the Environment, EarlyView.ABSTRACT The COVID‐19 pandemic has significantly affected small‐ and medium‐sized enterprises (SMEs) and poses challenges in acquiring financing. Growing green investments require transformative infrastructure and innovative green financing solutions. Blockchain technology is ideal for delivering green environmental information because it provides real‐

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 ...

Using Conditional Copula to Estimate Value-at-Risk in Vietnam's Foreign Exchange Market [PDF]
, 2014 In this paper, we briefly review the basics of copula theory and the problem of estimating Value-at-Risk (VaR) of portfolio composed by several assets. We present two VaR estimation models in which each return series is assumed to follow AR(1)-GARCH(1, 1)

Kybernetika, 2005 Summary: Transformations of copulas by means of increasing bijections on the unit interval and attractors of copulas are discussed. The invariance of copulas under such transformations as well as the relationship to maximum attractors and Archimax copulas is investigated.
