Abstract
This study analyzes strategic competition in the global pistachio market and identifies optimal trade strategies for Iran through an integrated game-theoretic framework. Five principal actors—Iran, the United States, China, the European Union, and the United Arab Emirates—are examined within a three-layer model. The framework combines: (1) a Stackelberg structure in which Iran acts as the price-setting leader; (2) a Cournot model in which the United States and China simultaneously determine output quantities; and (3) a simultaneous-move Nash framework capturing the roles of the European Union as a trade regulator and the United Arab Emirates as a logistics facilitator. The model enables simulation and quantification of the effects of key variables, including global prices, logistics costs, product processing levels, pistachio quality, sanctions, and trade tariffs, on Iran’s market share and export revenues. The findings indicate that improvements in product quality, reduction of trade barriers, enhancement of packaging and processing, and optimization of supply chains are decisive for maintaining and expanding Iran’s global market share. Furthermore, diversification into emerging markets and the adoption of flexible pricing strategies strengthen Iran’s capacity to respond to intensifying competition from the United States and China. Policy recommendations include targeted investment in export infrastructure, facilitation of access to destination markets, elevation of international quality standards, and reduction of transaction and transportation costs. The principal contribution of this study lies in integrating three strategic game-theoretic approaches to model a real agricultural market operating under sanction conditions. The proposed framework functions both as a predictive policy tool and as a practical guide for policymakers and stakeholders in designing and implementing effective trade strategies.
Purpose/Aims:
This study investigates the dynamics of strategic competition in the global pistachio market, with particular emphasis on strengthening Iran’s competitive position amid intensifying international rivalry. Given the central roles of Iran, the United States, China, the European Union, and the United Arab Emirates in shaping market outcomes, the research employs a multi-layer game-theoretic framework to capture the strategic interdependencies among these actors.
By integrating Stackelberg, Cournot, and simultaneous-move Nash frameworks, the study develops a comprehensive analytical structure capable of simulating the effects of global prices, logistics costs, product quality, processing levels, and trade sanctions. The overarching objective is to introduce effective strategies for sustaining and enhancing Iran’s export performance under real-world constraints, thereby offering practical insights for policymakers and stakeholders in the agricultural export sector.
Methodology & Framework:
The study introduces a mixed analytical framework that integrates three complementary game-theoretic models within a unified structure.
In the Stackelberg Competition, Iran is modeled as the price-setting leader that determines export prices while anticipating and incorporating the strategic reactions of competing exporters.
In the Cournot Competition, the United States and China are treated as quantity-setting competitors that simultaneously adjust production levels in response to prevailing market conditions and Iran’s pricing strategy.
In the simultaneous-move Nash framework, the European Union and the United Arab Emirates influence market equilibrium through regulatory and logistical channels. The European Union is modeled as a trade regulator affecting tariffs and quality standards, whereas the United Arab Emirates functions as a logistics facilitator shaping trade flows and transportation efficiency.
Scenario-based simulations are conducted to assess the effects of variations in global market prices, logistics costs, transportation efficiency, processing levels, packaging quality, sanctions, and trade barriers. The integrated model quantifies the impact of these variables on Iran’s market share, export revenues, and overall competitiveness across different strategic configurations.
Findings:
The results demonstrate that improvements in product quality, reductions in trade barriers, and enhanced logistics efficiency are critical determinants of Iran’s global market share. Upgrading packaging, branding, and processing capabilities increases pricing power and strengthens customer retention.
Expansion into emerging markets reduces dependence on traditional trading partners and enhances strategic flexibility. Flexible pricing strategies improve responsiveness to competitor actions and market fluctuations.
Sanctions and trade restrictions exert a significant and nonlinear effect on export revenues, particularly when logistics costs are elevated. Under various simulated scenarios, optimal strategic adjustments enable Iran to stabilize or even expand its market share despite aggressive pricing behavior by competitors.
Discussion:
The findings confirm that an integrated game-theoretic framework provides a robust analytical tool for forecasting outcomes in complex agricultural trade markets. Modeling Iran as a Stackelberg leader yields realistic representations of competitive dynamics, especially in politically sensitive and sanction-constrained environments.
The interaction among pricing leadership, quantity competition, and regulatory-logistical influences underscores the necessity of coordinated policy and market strategies. The mixed-model structure captures the layered nature of strategic behavior in international agricultural trade more effectively than single-model approaches.
Conclusion & Implications:
The analysis supports several policy recommendations. Strategic investment in export infrastructure—particularly storage facilities, transportation networks, and port logistics—can substantially enhance competitiveness. Facilitating market access through trade diplomacy and diversified supply chains reduces vulnerability to external shocks. Establishing and enforcing higher quality standards differentiates Iranian pistachios in premium segments. Furthermore, optimizing logistics and customs procedures reduces transaction costs and improves export efficiency.
The integrated Stackelberg–Cournot–Nash framework offers a practical decision-support tool for policymakers, exporters, and trade analysts. By aligning production, pricing, and marketing strategies within a coherent strategic structure, Iran can maintain and strengthen its competitive position despite international trade constraints and intensifying global competition.
