Global Value Chains

Global Value Chains (GVCs) describe the fragmentation of production across borders, where different stages of making a good or service — research, component manufacturing, assembly, branding, logistics, after-sales — are performed in different countries by different firms, often coordinated by a lead multinational. The concept gained analytical traction in the 1990s and 2000s through scholars such as Gary Gereffi, who distinguished buyer-driven chains (e.g., apparel, retail, dominated by brands like Walmart or Nike) from producer-driven chains (e.g., automotive, electronics, dominated by manufacturers like Toyota).

GVCs are measured using trade-in-value-added statistics. The OECD–WTO TiVA database and the World Bank's World Development Report 2020: Trading for Development in the Age of Global Value Chains are the standard references. Roughly half of world trade is estimated to occur within GVCs, although the share plateaued after the 2008 financial crisis.

Key features researchers track:

• Upgrading: how firms or countries move from low-value tasks (assembly) to higher-value tasks (design, R&D, branding) — the so-called "smile curve."
• Lead firm governance: whether coordination is hierarchical, captive, relational, modular, or market-based.
• Concentration risk: dependence on a single supplier country or chokepoint, exposed by the COVID-19 pandemic, the 2021 Suez Canal blockage, and US–China semiconductor tensions.

GVCs are central to debates on industrial policy, friend-shoring, near-shoring, and economic security. The US CHIPS and Science Act (2022) and the EU Chips Act (2023) explicitly aim to reshape semiconductor GVCs. The WTO, UNCTAD, and the ILO also examine GVCs for their effects on labor standards, since lead firms often outsource compliance risk to suppliers in lower-wage jurisdictions.

For MUN delegates, GVCs typically arise in committees on trade, development, supply-chain resilience, decent work, and critical minerals.
