Leveraging Reverse Engineering for CSCM Practices: Demystifying the Roles of Compositional Capability and Cooperative Orientation Under Humane Orientation and Competition Intensity

Business Strategy and the Environment, EarlyView.
ABSTRACT Circular supply chain management (CSCM) practices are seen as a solution for addressing society's many significant environmental challenges. Although existing studies recognise the importance of reverse engineering in combating poverty, there is limited knowledge about its effectiveness in shaping CSCM practices to address climate change and ...

Some New Bivariate Properties and Characterizations Under Archimedean Copula

Mathematics
This paper considers comparing properties and characterizations of the bivariate functions under Archimedean copula. It is shown that some results of the usual stochastic order for the bivariate functions in the independent case are generalized to the ...

The Perils of Environmental, Social, and Governance (ESG) Controversies: Implications for a Firm's Financial and Nonfinancial Performance

Business Strategy and the Environment, EarlyView.
ABSTRACT Although ESG controversies are on the rise, research investigating them yields contradictory findings. The paper provides resolutions to the debate through investigating (a) how ESG controversies influence firms' short‐term and long‐term financial performance; (b) how firms navigate ESG controversies' effect; and (c) how ESG controversies ...

Sound Financial Practices and Entrepreneurs' Socio‐Environmental Commitment: Revealing the Role of Financial Barriers

Business Strategy and the Environment, EarlyView.
ABSTRACT Small enterprises (SEs) constitute a major component of economic systems, and their socio‐environmental commitment is critical for promoting societal well‐being. This paper examines the direct effect of sound financial practices on socio‐environmental commitment and evaluates the mediating role of financial constraints—specifically debt and ...
