Modern production is not organised country by country but in global value chains — a single product made across many countries, each contributing a task. This 'unbundling' (Baldwin) has transformed how development through trade can happen, creating both an opportunity (join a chain rather than build a whole industry) and a trap (get stuck doing low-value tasks). This module covers GVCs and the upgrading challenge at the heart of African industrialisation.
The fragmentation of production
Traditional trade was in finished goods (a country made a car and exported the car). Modern trade is increasingly in tasks and intermediate inputs (Grossman-Rossi-Hansberg): a product's design, components, assembly, and marketing happen in different countries, and the half-finished goods cross borders multiple times. A smartphone is designed in one country, its chips made in another, assembled in a third, and sold globally. Richard Baldwin calls this the 'second unbundling' (after the first unbundling that separated production from consumption): the separation of production itself into stages across countries, enabled by falling communication and coordination costs. This fragmentation is the defining feature of modern globalisation and reshapes what development through trade means.
The smile curve
Where the value is
The smile curve maps the value-added along a value chain against its stages, and it is shaped like a smile: value-added is HIGH at the two ends — pre-production (R&D, design, branding) and post-production (marketing, distribution, after-sales) — and LOW in the middle (the actual manufacturing/assembly). So the firms and countries that capture the most value are those doing the design and branding (Apple designs and markets the iPhone) and those doing the assembly (in lower-wage countries) capture the LEAST — assembly is the low-value bottom of the smile. The implication is sobering for developing countries: simply attracting assembly (the classic 'factories and jobs' goal) captures the thinnest slice of the value, while the fat slices (design, branding) stay in rich countries. The development challenge is not just to JOIN a value chain (at the low-value assembly end) but to MOVE UP it toward the higher-value ends — which is the upgrading problem.
Upgrading
Moving up the chain
Gary Gereffi's GVC framework identifies types of upgrading — how a producer can capture more value: • Process upgrading — doing the same task more efficiently (lower cost, higher quality). • Product upgrading — moving to more sophisticated, higher-value products. • Functional upgrading — moving to higher-value FUNCTIONS in the chain (from assembly to design, or to branding and distribution — climbing the smile curve). • Chain upgrading — moving into an entirely new, higher-value chain (from garments to electronics). Functional upgrading (capturing the high-value ends) is the hardest and most valuable — and the most resisted by the lead firms that currently capture that value (they have no interest in helping a supplier become a competitor). The governance of the chain (who controls it — buyer-driven chains like apparel, vs producer-driven like autos) shapes how much upgrading a supplier can do. The upgrading question — can a country move from low-value assembly to high-value functions? — is the central trade-and-development question of the GVC era, replacing the old 'build a whole industry' framing.
GVCs and development: opportunity and trap
GVCs change the development calculus (World Bank WDR 2020). The opportunity: a country no longer needs to build an entire industry from scratch (the daunting ISI task) — it can join a global value chain by performing one task competitively (e.g., garment assembly), gaining jobs, foreign exchange, technology transfer, and a foothold from which to upgrade. This is a lower bar to industrialisation, and it is how East Asia and then China industrialised (joining and climbing chains). The trap: a country can get STUCK at the low-value assembly end — capturing the thin slice, dependent on the lead firm, unable to upgrade because the lead firm controls the high-value functions and the country lacks the capabilities (skills, technology, the binding constraints). Whether GVCs are an escalator (join low, climb up) or a trap (join low, stay low) depends on whether the country can upgrade — which depends on capabilities, the chain's governance, and policy. This is the modern form of the trade-and-development question.
Where Africa sits
Most African economies sit at the lowest-value end of value chains — exporting raw commodities (the rawest input, before even assembly) and a little low-value assembly. This is the GVC version of the commodity-dependence and tariff-escalation problems: Africa supplies the raw materials (cocoa beans, raw minerals, crude oil) and the value-added (processing, design, branding) happens elsewhere. The upgrading challenge is therefore acute: how to move from exporting raw cocoa to processing chocolate, from exporting raw cobalt to making battery components, from raw cotton to garments. The opportunities (agro-processing, joining manufacturing chains via regional markets, services and digital chains) and the obstacles (infrastructure, skills, the binding constraints, tariff escalation, lead-firm resistance) connect this module directly to the industrial-policy, AfCFTA, and tariff modules. The GVC lens reframes African development as a question of moving up chains — capturing more of the value of what the continent already produces — rather than building whole industries from scratch or remaining a raw-commodity supplier.
Exercise
An African country exports raw cashew nuts to Asia, where they are processed (shelled, roasted, packaged, branded) and sold globally at many times the raw price. The government wants the country to 'capture more of the value'. (1) Use the smile curve to explain where the value currently goes and why raw-nut exporting captures so little. (2) Identify the types of upgrading the country could pursue, from easiest to hardest. (3) Explain the obstacles to functional upgrading, including lead-firm resistance. (4) Connect this to tariff escalation and recommend a strategy drawing on the specialization.
