WEBINAR RECORDING · 2021-06
GVCs for LDCs
In this conversation: Lucian Cernat, presenting joint work with Alessandro Antimiani; discussant Marion Jansen; moderators Ben Shepherd and Hanna Norberg.
Lucian Cernat proposes letting preferences follow LDC inputs through third-country processing. Model simulations suggest additional exports and supply-chain integration. Marion Jansen tests the proposal's productivity assumptions, upgrading incentives, and implementation burden; the discussion also raises the unresolved distribution of tariff savings between LDC suppliers and downstream buyers.

FROM THE CONVERSATION
Three takeaways.
What they mean in practice.
Prepared from the session recording using automatic transcription and editorial review. Follow the timestamp links for the original wording and context.
Preferences could follow inputs through processing
Watch 17:02 ↗The proposal grants a tariff reduction on a processed product proportionate to its LDC input value. Cernat's example is Haitian mangoes embedded in third-country yogurt: duty-free access for mangoes alone does not remove tariffs encountered after transformation. Coordinated implementation would create incentives to source LDC inputs across destinations.
Policy interpretation: Analyze indirect market access through supply chains, alongside tariffs on direct LDC exports.
The gains are simulated and assumption-dependent
Watch 21:10 ↗The CGE exercise compares a projected 2025 baseline with a proposal scenario and includes a productivity mechanism. Cernat reports increased LDC exports with small nonnegative effects for other country aggregates. In response to Jansen, he says removing the productivity channel reduces LDC benefits; the recording does not provide a complete numerical sensitivity table.
Policy interpretation: Present scenario gains with their assumptions and sensitivity analysis, rather than describing them as observed outcomes or a universal no-losers result.
Upgrading and supplier gains are not automatic
Watch 46:24 ↗Cernat argues that processing more within an LDC increases the preference benefit and could attract investment. However, he acknowledges that FDI is not explicitly modeled. Discussion distinguishes the aggregate opportunity from bargaining over the premium and from supply constraints such as electricity, finance, and skills.
Policy interpretation: Assess who captures the preference, what production stages are feasible locally, and which complementary investments are necessary.
From the discussion
Jansen questions whether the productivity feedback drives the favorable results and whether the policy instead supports processing abroad (37:44–39:33). Cernat defends incentives for incremental LDC processing but acknowledges modeling limits (48:20–50:39). Shepherd asks who captures gains along the chain (52:25–55:07); Cernat treats this as an empirical bargaining question. On origin documentation, he proposes carrying existing certificates forward and eventually digitizing them (43:32–46:24). Jansen ultimately endorses taking the proposal to policymakers (61:43–62:39).
