Non-Tariff Measures Trickling
through Global Value Chains
Annual PRONTO Confrence
Vienna, 26-27 February 2016
This paper was produced as part of the project "Productivity, Non-Tariff Measures and Openness" (PRONTO) funded by the European
Commission under the 7th Framework Programme, Theme SSH.2013.4.3-3 "Untapped Potential for Growth and Employment Reducing
the Cost of Non-Tariff Measures in Goods, Services and Investment", Grant agreement No. 613504.

NTM Broad Categories:
- Unilateral standards, and qualitative regulations: Technical Barrier to Trade (TBT), Sanitary
and Phytosanitary Measures (SPS)
- Bilateral quantitative and counter measures: Anti Dumping (AD), quantitative restrictions (QR),
safeguard measures (SG), and special safeguards (SSG)
Some quality issues: (e.g. national legal bases, national security, health and environment issues, market
adjustments, etc.)
- Reverse notifications: Specific Trade Concerns (STCs) on TBT and SPS
Global value chains (GVC):
- Trickling through GVC
4-stage methodology:
- Bilateral import demand elasticities
- AVE for NTMs
- Cumulative AVEs in GVCs
- Productivity growth

- where 𝑠ℎ𝑖𝑗𝑡 is the share of import value of product h from country j to country i in the GDP of the
country i at time t; 𝑝ℎ𝑖𝑗𝑡 is the price (unit value) of the imported product; 𝑣𝑚𝑖
𝑡 and 𝑣𝑙𝑖𝑡 refer to the
factors m and l in the production of GDP of country i; and 𝑝−ℎ𝑖𝑡 is the Tornqvist price index (Caves
et al., 1982) of all other goods constructed using the GDP deflator 𝑝𝑡
- Merits in comparison with Kee et al. (2008): efficiency gains using exporter interactions 𝑎ℎ𝑗, and
controlling for other goods’ prices

2. AVE for NTMs:
- Extending the approach proposed by Kee et al. (2009)
- ln 𝑚𝑖𝑗ℎ𝑡 = 𝛼1ℎ + 𝑘 𝛼1𝑘𝐶𝑖𝑗𝑡𝑘 + 𝛼1ℎ𝑡 ln 1 + 𝑇𝑖𝑗ℎ𝑡 + 𝑖𝑗=1
𝐼𝐽 𝑛=1𝑁 𝜔𝑖𝑗𝛽1𝑛ℎ𝑁𝑇𝑀𝑖𝑗ℎ𝑡 + 𝜔1𝑖𝑗ℎ +

- where ln 𝑚𝑖𝑗ℎ𝑡 is the natural log of the import quantity of product h to country i from country j at
time t; 𝐶𝑖𝑗𝑡𝑘 is the country-pair characteristics and consists of classical gravity variables and factor
endowments; 𝑇𝑖𝑗ℎ𝑡 is bilateral tariffs; and 𝜔𝑖𝑗 is country-pair dummies.
- Merits in comparison with Kee et al. (2008), Beghin et al. (2014), and Bratt (2014): Intensity of
different types of NTMs during time, variation in NTM impacts across exporters and importers in
addition to products.

3. Cumulative AVEs in GVCs:
- Three channels of trade policy measures (TPjht):
1. Direct protectionism trade policies (DBRI) in favour of domestic industry
2. Indirect trade policy measures (IBRI) accumulated through backward linkages
3. Trade policy measures (BRI) that the industry is facing while exporting to other destinations
- Having J country-sectors and considering backward linkages using WIOD:
𝐼𝐵𝑅𝐼 = 𝑒 × 𝐵 ×
𝑛=0
𝐴𝑛
′
= 𝑒 × 𝐵 × 𝐼 − 𝐴 −1 ′
where 𝐴𝑛 is the period-averaged of J by J matrices of technical coefficients, 𝑒 is a row vector of
ones, 𝐵 is a J by J matrix of element-by-element multiplication of technical coefficients and
tariffs 𝐵 = 𝐴:× 𝑇
IAVE for nine types of NTMs are calculate in addition to period-averaged IT

4. Productivity Growth:
- From a simple Cobb-Douglas function 𝑌𝑗ℎ𝑡 = Ψ𝑗ℎ𝑡𝐾𝑗ℎ𝑡𝛼 𝐿𝑗ℎ𝑡
𝛼 , Ψ > 0, 0 < 𝛼 < 1:
- ∆𝑦𝑗ℎ𝑡 = ∆Ψ𝑗ℎ𝑡 + 𝛼∆𝑘𝑗ℎ𝑡
- ∆𝜓𝑗ℎ𝑡 = 𝛾0𝑇𝑃𝑗ℎ𝑡 + 𝛾1𝐻𝑆𝑗ℎ𝑡
- ∆𝑦𝑗ℎ = 𝛽0 + 𝛽1𝑦𝑗ℎ,𝑡0 + 𝛽2∆𝑘𝑗ℎ + 𝛽3𝐻𝑆𝑗ℎ + 𝛽4𝐷𝐵𝑅𝐼𝑖𝑗ℎ + 𝛽5𝐼𝐵𝑅𝐼𝑗ℎ + 𝛽6𝐵𝑅𝐼𝑗ℎ + 𝛾ℎ +
𝛾𝑖𝑗 + 𝜇𝑖𝑗ℎ
- where ∆𝑦𝑗ℎ is the average annual labour productivity growth of industry h in country j from 2002 to
2009 , 𝑦𝑗ℎ,𝑡0 is the initial level of productivity in logarithmic form, ∆𝑘𝑗ℎ is the average annual
growth of capital to labour ratio
Using 𝛾ℎ and 𝛾𝑖𝑗 we control for industrial and country-pair effects
Estimations are divided in to services and non-services categories
Two measures of value added (VA) and gross output (GO) labour productivities are used as dependent variables
First specification covers only BRIs and the second covers all AVEs for 9 NTMs and tariffs
