S.I. Journal: Decisions in Economics and Finance (Springer)
The study of equilibrium problems provides a broad unifying setting for the analysis of several mathematical problems and real-world applications in several fields. With equilibrium problems, we refer to a mathematical formulation that allows us to cover complementarity models, variational and quasi-variational inequalities, scalar/vector/bilevel/stochastic/robust optimization problems that could be applied to economics, finance, decision theory, statistics, engineering, networks, and computer science. In this context, the main challenge is to find effective solutions to problems arising from the new scientific frontiers. The scope is to reduce the gap between theory and practice.
With this spirit, we are very pleased to announce a special issue of Decisions in Economics and Finnce titled “Equilibria and Applications”. This special issue aims to collect both theoretical and computational developments as well as innovative applications on the following topics:
- Equilibrium problems.
- Nonlinear optimization.
- Quasi-variational inequalities.
- Generalized Nash Equilibrium Problems (GNEPs).
- Network equilibrium problems.
- Bilevel programming, MPEC, EPEC.
- Multi-Leader-Follower games.
- Variational Analysis.
- Decision theory.
- Stochastic programming.
- Robust optimization.
- Risk management.
- Sustainability.
- Energy economics and finance.
- Electricity markets.
This Special Issue seeks to publish novel research and reflect the most recent advances on the latest contributions in the above areas, covering new modeling techniques and formulations, as well as innovative case studies. Only original contributions of the highest quality will be included.
The opening date for the special issue is July 1, 2025.
The closing date for submissions is December 31, 2025.
Manuscript Submission
Submitted papers should be original works and should not have been previously published nor be currently under consideration for publication elsewhere. The manuscripts should be prepared in keeping with the Instructions for Authors provided on the Decisions in Economics and Finance homepage.
All manuscripts should be submitted electronically using the journal’s online manuscript submission system.
Authors: please select “S.I.: Equilibria and Applications” when you reach the “Additional Information” step in the submission process.
While ensuring the high quality of the works to be published, the journal will follow an accelerated review process. The first round of referee reports will be completed by March 31 2026, and the complete special issue should appear in October 2026. Upon acceptance, papers will be published online. All papers will be refereed according to the journal’s procedures and standards.
