Skorokhod problem for Lévy Processes
, 2017 We discuss a new strategy to solve the Skorokhod problem which is generic in the sense that it can be applied to many Markov processes. For the special case of Lévy processes we derive necessary and sufficient conditions (extending earlier work of ...

Governance Drivers of Fossil Fuel Divestment: Evidence From Global Banks
Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT Climate change poses increasing transition risks for the banking sector, as financial institutions remain exposed to fossil fuel activities despite growing sustainability commitments. This study examines whether corporate governance influences banks' decisions to adopt fossil fuel divestment policies.

The Production of a Sustainability Reporting Norm in Spanish State‐Owned Enterprises
Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT State‐owned enterprises (SOEs) are hybrid organizations that pursue social and economic goals and are expected to engage in sustainability reporting. Previous literature has shown limited attention to examining the process by which a norm in sustainability reporting has emerged among SOEs.

Bitcoin Volatility and Intrinsic Time Using Double-Subordinated Lévy Processes
RisksWe propose a doubly subordinated Lévy process, the normal double inverse Gaussian (NDIG), to model the time series properties of the cryptocurrency bitcoin. By using two subordinated processes, NDIG captures both the skew and fat-tailed properties of, as

Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT In the discourse on environmental sustainability and energy security, energy management is an inevitable policy issue that requires research‐based solutions. Based on this, the present study contributes by examining the impact of environmental, social, and governance (ESG) uncertainty on energy consumption patterns in the USA from 2002 to 2024.

Constructions of coupling processes for Lévy processes
, 2011 We construct optimal Markov couplings of Lévy processes, whose Lévy (jump) measure has an absolutely continuous component. The construction is based on properties of subordinate Brownian motions and the coupling of Brownian motions by ...
