Energy Market and Carbon Emission Spillovers in Critical Minerals Investment: A Dynamic Connectedness Approach
Haibo Wang, Lutfu Sua, Jaime Ortiz +2
Design/methodology/approach A time-varying parameter vector autoregression (TVP-VAR) model is employed to quantify dynamic connectedness and directional volatility spillovers using…
Dynamic Risk in the U.S. Banking System: An Analysis of Sentiment, Policy Shocks, and Spillover Effects
Haibo Wang, Jun Huang, Lutfu S Sua +3
The 2023 U.S. banking crisis propagated not through direct financial linkages but through a high-frequency, information-based contagion channel. This paper moves beyond exploration…
A Heuristic Framework of Variable Neighborhood Descent Methods for the Large-Scale Multi-Level Facility Location Problem in Supply Chain Networks
Haibo Wang, Bahram Alidaee
This paper addresses the single-assignment, uncapacitated, multi-level facility location (MFL) problem, a strategic decision-making process critical to the design of long-term supp…
Renewable Energy Prediction: A Comparative Study of Deep Learning Models for Complex Dataset Analysis
Haibo Wang, Jun Huang, Lutfu Sua +1
