Non-tariff measures, preferential trade agreements, and prices: new evidence

Combining for the first time a new dataset of non-tariff measures (NTMs) in 65 countries with the CEPII's unit values database, we estimate average ad-valorem equivalents (AVEs) for sanitary and phytosanitary, technical-barriers-to trade and other measures by section of the Harmonized System of product classification. While most existing AVEs are obtained from indirect quantity-based estimation, ours are obtained from direct price-gap estimation. They lie in a single-digit range, i.e. substantially lower than previous estimates based on older data. Our results may reflect the progressive phasing out of command-and-control instruments such as quantitative restrictions in many countries; they also suggest that sanitary and technical regulations have not substituted for them as trade-restrictive interventions. Most interestingly, we show that deep-integration clauses in regional trade agreements, in particular the mutual recognition of conformity-assessment procedures, substantially reduce the price-raising effect of NTMs, possibly reflecting lower compliance costs
