Trade and Commitment to Development: Which Is More Damaging to Development, Agricultural Subsidies or Trade Tariffs?

On September 5, we launched the results of the 2017 Commitment to Development Index (CDI), which scores 27 countries on how development-friendly their policies are. This year, we include two new indicators assessing how rich-country “tariffs” (taxes on imports) and “subsidies” (payments to domestic producers) inhibit development. But which is more damaging, and therefore deserves a greater weight in the Index?

Using the approach embedded in previous CDI calculations, we calculate that tariffs may be over three times as damaging as agricultural subsidies in inhibiting developing country trade. Below, we look at how tariffs and subsidy inhibit development, and assess their respective impact.
