Testing for Contagion in International Financial Markets: To See More, Go Higher

Financial Review, Volume 61, Issue 3, Page 725-763, August 2026.
ABSTRACT Traditional measures of financial contagion rely on correlation shifts, overlooking higher moments such as skewness and kurtosis. We examine contagion during two major financial crises, incorporating lower‐ and higher‐moment measures. We analyze stock market returns from 22 major markets at different frequencies, offering a global perspective ...

Optimal Control of Mobile Energy Storage via Knowledge‐Guided Deep Reinforcement Learning

Battery Energy, Volume 5, Issue 4, July 2026.
This research proposes a Knowledge‐Guided DRL framework (KA‐DDPG) for mobile energy storage. By integrating offline optimization as expert guidance to manage hybrid action spaces and environmental uncertainties, our method achieves significantly higher arbitrage profits and superior operational stability compared to standard reinforcement learning and ...

Electricity Price Prediction Using Multikernel Gaussian Process Regression Combined With Kernel‐Based Support Vector Regression

Journal of Forecasting, Volume 45, Issue 4, Page 2059-2077, July 2026.
ABSTRACT This paper presents a new hybrid model for predicting German electricity prices. The algorithm is based on a combination of Gaussian process regression (GPR) and support vector regression (SVR). Although GPR is a competent model for learning stochastic patterns within data and for interpolation, its performance for out‐of‐sample data is not ...

Further Considerations Needed to Assess Reshoring: Its Impact on Host Communities

Business Ethics, the Environment &Responsibility, Volume 35, Issue 3, Page 2401-2411, July 2026.
ABSTRACT After several decades of offshoring, reshoring is becoming an emergent strategy in many countries and industries. Both governments compel firms to reshore their production to their home countries as firms find, in some cases, that it is more profitable for them to do so.
