Philippe Solal

Philippe Solal is a Professor of Economics at the University of Saint-Etienne, affiliated with GATE Lyon Saint-Etienne (UMR CNRS 5824), a research center focusing on economics and management science. His academic career spans several decades of research and publication in game theory and economic theory.

Professor Solal's research focuses on:

• Cooperative game theory, particularly solution concepts like the Shapley value and its variants
• Social choice theory, including voting systems and ranking methods
• Coalition formation and stability in cooperative games
• Applications of game theory to economic problems and network structures

His recent publications (2021-2025) demonstrate continued theoretical innovation in cooperative game theory, with emphasis on axiomatic characterizations, coalition structures, cost allocation problems, and social choice mechanisms. His work often involves collaborations with researchers across France, particularly with E. Rémila and S. Béal.

Professor Solal has supervised five PhD students who have secured academic positions at French universities:

• Techer K. (2023) - Maître de Conférences at University of Franche-Comté
• Lowing D. (2022) - Maître de Conférences at ENS Rennes
• Lardon A. (2011) - Maître de Conférences at University of Saint-Etienne
• Ghintran A. (2009) - Maîtresse de Conférences at University of Lille
• Béal S. (2005) - Professor at University of Franche-Comté

His research has practical applications in transportation networks, river sharing problems, and cultural policy. His work maintains strong connections between theoretical game theory and real-world economic problems.
