The Governing Numbers: Applications Of Game Theory And Linear Programming In The Italian Economy
Authors : Tamma Ahmed .
Abstract
This paper examines the structural and strategic dimensions of the Italian economy through the lens of applied mathematics, specifically Linear Programming (LP) and Game Theory. Italy's economic fabric — characterized by a renowned luxury manufacturing sector, a fragmented Small and Medium Enterprise (SME) landscape, and chronic structural challenges including tax evasion and regional agricultural inefficiency — presents an ideal case study for quantitative policy modeling. This study formulates LP models for the "Made in Italy" luxury supply chain and for southern agricultural cooperatives, deriving optimal production mixes and shadow prices for scarce resources via numerical MATLAB implementation. Complementing these, game-theoretic frameworks model the Taxpayer–Revenue Agency interaction as a mixed-strategy non-cooperative game, deriving an equilibrium audit rate of 28.6% against a 4.5% evasion rate, and model SME industrial districts as infinitely repeated Prisoner's Dilemma games, establishing a critical cooperation threshold of δ* = 0.333 that all observed Italian district archetypes comfortably clear. Numerical results reveal that the luxury manufacturing optimum is constrained by carbon-allowance availability rather than artisanal labour — a finding that revises the conventional labour-scarcity narrative and redirects policy emphasis toward emissions-trading flexibility. Taken together, the findings demonstrate that quantitative modeling is not a theoretical luxury but a governance necessity for Italy's economic resilience
