Capability-Based Tariff Policy

mental-model

A tariff is not inherently pro- or anti-development; its value depends on whether domestic producers have no plausible capability, are still building it, or have already matured. Protection should appear only in the middle stage and disappear once it has done its job.

The same country could rationally put no tariff on an imported product, later impose one, and then remove it again. In the debate over whether India should buy milk from the United States, the apparent contradiction becomes a sequence: openness before a domestic industry exists, protection while it develops, and openness again after it matures.

Match the barrier to the capability stage

Tariffs change the competitive environment, but that helps only at a particular stage. Where no credible domestic capability exists, making imports expensive does not conjure an industry into being. Once a fledgling industry is present, temporary shelter can give it room to develop. After it becomes capable, continued protection stops serving the original purpose: the industry should face outside competition again. The policy variable is therefore not simply the tariff rate, but the sector's position on a capability curve. This makes Infant Industry Protection inseparable from Time-Bound Industrial Policy: the case for entry protection must contain a case for eventual exit.

The hard part is diagnosing maturity

The three-stage rule does not tell policymakers how to prove that an industry is genuinely fledgling, when it has matured, or whether it ever had a plausible path to capability. If those judgments are wrong—or politically manipulated—temporary shelter can become permanent protection for an industry that never becomes competitive.

E1

Demand a stage and an exit test

When evaluating a proposed tariff, require its advocates to name the sector's current capability stage and specify the observable milestone that will trigger removal. If they cannot explain both why protection is warranted now and what success would make it unnecessary, the policy is not capability-based.
