Waves of Uncertainty: Crude Oil Under Geopolitical, Economic, and ESG Turbulence

open access: yesEnergy Science &Engineering, Volume 14, Issue 3, Page 1258-1272, March 2026.
Dynamic copula and wavelet coherence reveal that geopolitical, economic, and sustainability uncertainties significantly shape crude oil price co‐movements. Long‐term coherence, especially post‐2015, highlights the growing role of ESG risks alongside geopolitical shocks and economic crises in global energy risk transmission.

Utvärdering av DCC-GARCH

open access: yes, 2021
When modelling more that one asset, it is desirable to apply multivariate modeling to capture the co-movements of the underlying assets. The GARCH models has been proven to be successful when it comes to volatility forecast- ing.

Systemic risk in the insurance sector: A semi‐parametric approach based on Spearman's rho

open access: yesRisk Management and Insurance Review, Volume 29, Issue 1, Page 64-98, Spring 2026.
Abstract We propose a new method to measure systemic risk in the global insurance sector by analyzing interconnectedness among firms under different market conditions. Using a semi‐parametric approach that relies on the Spearman correlation and copula‐based partial dependence, we assess relationships in relatively stable, extremely bullish, and ...

Optimal Operation and Photovoltaic Consumption Assessment of Active Distribution System Considering Photovoltaic Output Dynamic Correlation

open access: yesIET Renewable Power Generation, Volume 20, Issue 1, January/December 2026.
This study proposes an optimal operation framework for active distribution networks that explicitly captures dynamic PV correlation using a SARIMA‐DCC‐GARCH model. By integrating affine power flow analysis with flexible resource scheduling, the method effectively maximises photovoltaic consumption and minimises operational costs while ensuring voltage ...
