Abstract
In this paper we examine the impact of non-tariff measures (NTMs) on
imports at the 6-digit level of the Harmonised System over the period 2002-
2011. We draw on information of NTMs notified to the WTO from the
Integrated Trade Intelligence Portal (I-TIP), distinguishing various NTM
types, such as technical barriers to trade and sanitary and phytosanitary
measures. To assess whether NTMs facilitate or impede trade across
countries we apply a gravity approach, which allows calculating implied ad
valorem equivalents of NTMs for 103 WTO member countries. These can be
differentiated by NTM types, income groups, industries and product
categories. Furthermore, we compare the effects of NTMs along the broad
economic categories (BEC) classification to evaluate whether the effects of
NTMs differ between intermediary products and final goods.

1. Introduction
The general trend towards an increasing use of NTMs as specific trade policy measures,
the abrupt increase in the number of non-tariff measures (NTMs) notified to the WTO
during the recent financial crisis and its importance in the negotiations of recent trade
agreements stimulated discussions on the political economy of NTMs. With respect to
imports from developing countries, the launch of the Sustainable Development Agenda
in September 2015 might anew boost research in this field beyond the focus on
advanced economies.
Non-tariff measures need not be non-tariff barriers. In the presence of information
asymmetries, the imposition of standard-like NTMs – e.g. a minimum quality standard –
can increase consumer trust, decrease transaction costs and promote trade.
Furthermore, exporters and domestic producers differ in their capacities to cope with
new standards. Therefore, the implementation of a new NTM might in the end increase
the imports of the NTM imposing country.
Many studies focus on the trade effects for specific products, resulting from the
imposition of one specific NTM for a group of countries. For example, Disdier et al
(2008) find that EU sanitary and phytosanitary measures (SPS) and technical barriers to
trade (TBT) are more trade restrictive than any other OECD standards, however,
without distinguishing between the effects of SPS measures and TBTs. Findings by Kee
et al (2009) underpin the view that NTMs serve as tariff substitutes rather than tariff
complements. In addition, they find greater import impeding effects for the agricultural
sector than for the manufacturing sector. Yet, they restricted non-tariff measures to be
non-tariff barriers, i.e. to have a negative impact on trade, by imposing parameter
restrictions. Bratt (2014) and Beghin et al. (2014) follow up on Kee et al (2009) and also
allow for trade-promoting effects of NTMs, which they find for 46% and 39% of the
products affected, respectively.
However, none of the mentioned studies allows for a differentiation of effects across
different NTM types. This paper aims to fill this gap by using a rich data compilation of
WTO notifications. The WTO provides comprehensive data on NTM notifications via the
Integrated Trade Intelligence Portal (I-TIP). Ghodsi et al (2015a) enhanced the value of
this database for economic analysis by matching missing HS codes to these notifications.
Using this information, this paper distinguishes between several categories of NTMs,
with special attention given to the analysis of sanitary and phytosanitary measures and
technical barriers to trade. Furthermore, working with this unique dataset allows
evaluating the trade effects of NTMs by means of an intensity measure, i.e. by counting
how many NTMs a specific importing country imposed against a trading partner for each
product at the 6-digit level of the Harmonised System (HS). Using this intensity measure,
we estimate the impact of NTMs on import flows to the NTM-imposing country using a
gravity framework. Allowing for both import promoting and import impeding effects of
NTMs, we calculate the ad valorem equivalent (AVE) of each NTM type for each
imposing country at the 6-digit product level of the Harmonised System (HS) for the
period 2002-2011. The remainder of this paper is structured as follows. Section 2 gives a
3
brief overview of the literature. Section 3 describes our methodology and data to
estimate AVEs with empirical results presented in Section 4. The final section concludes.
2. Literature Review
The enormous speed with which NTMs spread as trade policy instruments is reflected
in the fast growing literature on their economic effects. Van Tongeren et al. (2009),
Beghin et al. (2012) and Ghodsi (2015a), for example, applied a partial equilibrium
framework for analysing the impact of NTMs, but also computable general equilibrium
models have been recently used e.g. by Francois et al. (2012) for this purpose. In order
to assess the impact of NTMs on international trade, often a gravity estimation approach
is followed, e.g. by Essaji (2008), Disdier et al. (2010), Yousefi and Liu (2013) and Ghodsi
(2015b). A way to directly compare the effects of NTMs on trade with the impact of
tariffs on trade is to compute the ad valorem equivalents (AVEs) of NTMs, which was
done e.g. by Kee et al. (2009), Bratt (2014), Beghin et al. (2014) as well as Cadot and
Gourdon (2015). Ferrantino (2006) offers a detailed description of methods frequently
used to quantify the effects of NTMs on trade flows and prices by NTM type.
One method to calculate AVEs is to analyse the price wedge resulting from the
implementation of NTMs, applied e.g. by Dean et al. (2009), Rickard and Lei (2011) and
Nimenya et al. (2012). The amount of information necessary for this analysis restricts
most of the papers to the analysis of very few – mainly agricultural – products for a
small set of countries. The papers by Dean et al. (2009) and Cadot and Gourdon (2015)
are rare exceptions. Another drawback of this method is that domestic prices in the
absence of NTMs are not observable. Therefore, domestic prices affected by NTMs are
often directly compared to international prices, neglecting the possible impact of
differences in product quality. Furthermore, NTMs occur at different stages along the
supply chain, which makes a comparison of different prices along the production and
distribution chain (e.g. Cost, Insurance and Freight (CIF), Delivered Duty Paid (DDP)) for
a single product necessary. And in the case of prohibitive NTMs, no prices are
observable at all.
The other branch of literature has been triggered by a contribution of Kee et al. (2009),
who infer the AVEs of NTMs indirectly in a two-step approach. They assess the impact of
NTMs on the import values with a gravity model. The results are then converted to AVEs
using import demand elasticities, which are estimated beforehand. They find that the
average AVE of all products affected by NTMs is 45%, and 32% when weighted by
import values. Furthermore, they report a great variation of AVEs across products and
countries, with highest AVEs found for agricultural products and for low income
countries in Africa.
Importantly, Kee et al (2009) restricted their AVEs to be positive, i.e. by employing
parameter restrictions they forced all NTMs to have only import restricting effects
comparable to tariffs and quotas. Given market imperfections, NTMs can, however, also
serve to facilitate trade. Beghin et al. (2014) therefore, re-estimate the gravity approach
proposed by Kee et al. (2009) for standard-like NTMs for the years 2001 to 2003,
4
allowing for positive and negative values of AVEs of NTMs. In their analysis, 12% of all
products at the HS 6-digit level were affected by technical regulations. Out of these, 39%
exhibited negative AVEs – i.e. an import-facilitating effect. Bratt (2014) concludes, that
overall, NTMs impede rather than facilitate trade, with a median AVE of 15.7%.
However, 46.1% of all AVEs computed show a positive effect on trade. Distinguishing
between exporters and importers at different income levels, as well as between the food
and the manufacturing sector, he finds that the effects of NTMs are in the first instance
driven by the NTM imposing importing countries, where AVEs of NTMs are highest for
low income countries for both sectors. In addition, Bratt (2014) highlights that NTMs
targeting the food sector are more import restricting than NTMs in the manufacturing
sector.
The main advantage of the gravity approach in comparison to the price wedge
approach is that the former relies on trade data, which is more abundant at the
disaggregated product level than price data. In addition, it can be used for broad panel
analysis, i.e. for a big set of countries and products, with different NTMs evolving over
time. Yet, the indirect approach has drawbacks too. Like the price gap method, this
approach does not distinguish the quality of domestic from foreign goods, influencing
the impact of NTMs. In addition, AVE calculations are based on import demand
elasticities, which are themselves estimates.
Acknowledging the advantages and drawbacks of either approach, we aim to fill gaps
in the latter branch of literature triggered by Kee et al (2009). Previous calculations of
AVEs of NTMs (Kee et al., 2009; Bratt, 2014; and Beghin et al., 2014) were conducted on
cross sectional data due to lack of information on NTMs. Having a rich database on
NTMs obtained from WTO I-TIP we are extending their approach to a panel analysis.
Moreover, and maybe most importantly, previous calculations were not distinguishing
NTM types whose diverse attributes by motives would bring various trade
consequences. In this article, we differentiate major categories of NTMs, which can
provide better insights on the implications of the use of different NTMs. In addition, the
amount of applied NTMs was not considered in previous studies. Rather, the existence of
NTMs was captured by employing dummy variables. Our analysis, however, is based on
the intensity of use of NTM types by counting the number of imposed NTMs.
3. Data and Methodology
Given the steadily rising number of various types of NTMs and the resulting intense
political discussions surrounding their (potential) misuse as protectionist tools that
erode the economic benefits of preceding cuts in tariff rates, it is desirable to make them
directly comparable to tariffs. As mentioned in the literature review, there are two basic
approaches, how to compute respective AVEs of NTMs. A direct approach would be the
evaluation of differences in prices prior and after the NTM implementation (see e.g.
Dean et al., 2009). The indirect approach makes use of import demand elasticities and
was developed by Kee et al (2009). We add to the second branch of literature. It is a
three-step analysis, where first import demand elasticities are estimated. Second, a
5
gravity model is used to estimate the impact of NTMs on import quantities, where the
Heckman procedure accounts for zero trade flows. In the third and last step, this effect is
transformed into a price effect – i.e. the AVEs – using previously computed import
demand elasticities.
To capture the effects of NTMs, we make use of a rich data compilation of NTM
notifications provided by the WTO I-TIP covering 136 NTM imposing WTO members
targeting 179 countries or territories, which has been complemented with HS codes at
the 6-digit product level by Ghodsi et al. (2015a). For our analysis, we employ count
variables for the following set of NTM types1: (a) Sanitary and phytosanitary (SPS)
measures aim at protecting human or animal life and include e.g. regulations on
maximum residue limits of substances such as insecticides and pesticides, assessments
of food safety regulations or labelling requirements. (b) Technical barriers to trade
(TBTs) are standards and regulations not covered by SPS measures, such as standards
on technical specifications of products and quality requirements. As we are going to
show below, the number of notified SPS measures and TBTs increased dramatically
during the period under investigation. (c) Antidumping measures (ADP), countervailing
duties (CVD) and (special) safeguard ((S)SG) measures are counteracting measures and
are therefore temporarily implemented to counteract the negative effects resulting from
increasing imports, primarily due to trade policies considered as unfair. ADP is the most
prominent counteracting measure, aiming at combating (predatory) dumping practices
that cause injury to the domestic industry of the importing country. Countervailing
duties target subsidised exports, while safeguards apply for a specific product but for all
exporters in order to facilitate adjustment for the importing country. In the following
figures, we summarise countervailing duties and (special) safeguards under the
category of other counteracting measures (OCA) due to their small number. (d) The last
group of NTMs consists of the traditional trade policy tools of quantitative
restrictions (QRS) such as quotas. In addition, we look at specific trade concerns (STCs)
raised by WTO members at the TBT and SPS Committees2, which are by nature no NTMs,
but can nonetheless exhibit trade effects.
Figure 1 shows the stock of notified NTMs in 2011 for each NTM type, split up by the
21 sections of the Harmonised System (Version 2002). The three product groups that
faced the greatest number of total NTMs in 2011 (around 5000 each) belong to the agri-
food sector. As expected, SPS measures play a dominant role for those. Yet also other
quantitative restrictions, though small in number, are mainly applied to agri-food
products. They are followed by products of chemical industries as well as machinery and
electronical equipment for which around 4000 NTMs, mainly TBTs, were notified.
1 A detailed classification of types of NTMs, including examples, is provided by UNCTAD:
http://unctad.org/en/PublicationsLibrary/ditctab20122_en.pdf 2 The WTO provides information on the interpretation and application of Art. 13 of the Agreement on Technical
Barriers to Trade, which reads as follows: “Since its first meeting, Members have used the TBT Committee as a forum to discuss issues related to specific measures (technical regulations, standards or conformity assessment procedures) maintained by other Members. These are referred to as “specific trade concerns” (STCs) and relate normally to proposed draft measures notified to the TBT Committee or to the implementation of existing measures.” - In: https://www.wto.org/english/res_e/booksp_e/analytic_index_e/tbt_02_e.htm

Politically of great interest is also the question, whether richer or poorer countries are
the main applicants of NTMs. Figure 2 therefore summarises the stock of NTMs for the
year 2011 by income level of the imposing and the affected countries. Traditionally,
developed countries were the primary users of NTMs, with emerging countries catching
up. It is reasonable to expect developed countries to ask for higher standards for both
domestically produced and imported products and therefore to employ a greater
number of SPS and TBT measures.

Indeed, Figure 2 shows that by far the greatest number of imposed NTMs is
attributable to high income countries, accounting for 57.3% in comparison to 2.4% for
low income countries. However, it has also to be kept in mind that the data presented
are notifications to the WTO, which might be of greater risk to be incomplete for
developing countries. The numbers shown for affected countries are much lower, as we
excluded all NTMs which apply for all exporters from the graph, which substantially
reduces the number of SPS measures and drops TBTs, and (special) safeguards from the
picture. What is left are mainly antidumping measures, which are foremost addressing
upper middle and high income countries. Yet, all measures that are applied to all trading
partners not shown in the graph enter our analysis.
Figure 3 illustrates the evolution of notifications over time, depicting the number of
annual notifications for the period 1995 to 2011. There is a clear upward trend in the
number of SPS measures and TBTs, which account for 38.6% and 47.5% of all NTM
notifications (not including specific trade concerns) for our sample period (2002-2011),
respectively. The number of annual ADP notifications, however, has been decreasing
since their peak in 2002, when they represented 19% of all NTMs imposed. Still, they
form the third largest NTM group, with a share of 10.7% of all notifications between
2002 and 2011. The number of counteracting measures is mainly driven by special
safeguard measures, showing three peaks in 1999, 2002 and again 2004. Yet, they
account for only 2.6% of all NTMs notified to the WTO during the period of our empirical
investigation. Quantitative restrictions amount to even less, with a share of only 0.5% of
NTMs notified. However, like TBTs and SPS measures, they usually address a big number
of exporters, which significantly changes their magnitude when we consider our
bilateral data set.

The number of bilateral product lines targeted by an NTM more than quintupled from
8 million HS 6-digit product lines in 2002 to 50.2 million bilateral product lines in 2011.
While TBTs, SPS measures and QRS usually target a large number of exporters, if not all,

safeguard measures) specific exporters, which reinforces the dominance of SPS
measures and TBTs in the bilateral setting.
In order to evaluate the impact of NTMs, we consider a panel of bilateral import flows
of 135 WTO members from all their trading partners at a 6-digit product level for the
period 2002 to 2011. Data availability reduces our country sample from 160 WTO
members in 2014 to 135 countries, of which for the period under investigation (2002-
2011) 119 countries reported to have at least one NTM in force. The final result of our
empirical investigation is a collection of AVEs for 103 countries.
Given the large number of zero trade flows, we make use of the Heckman two-stage
estimation procedure to address the possible selection bias as follows.
𝑃𝑟𝑜𝑏[𝑚𝑖𝑗ℎ𝑡 > 0] = 𝛼0ℎ + 𝛼1 ln(1 + 𝑡𝑖𝑗ℎ𝑡) + ∑ 𝛼2𝑛 𝑁𝑇𝑀𝑛𝑖𝑗ℎ𝑡

(2)
In a first step, the selection equation (1) evaluates the probability of non-zero trade
flows for specific country pairs. From this first step, the inverse Mills ratio (𝜙𝑖𝑗ℎ𝑡) is
obtained, which enters the outcome equation (2) in the second step as an explanatory
variable. 𝑚𝑖𝑗ℎ𝑡 denotes the imports of product ℎ to country 𝑖 from partner country 𝑗 at
time 𝑡. Both equations are run separately for each product h at the HS 6-digit level.
Therefore, 𝛼0ℎ and 𝛽0ℎ represent product specific fixed effects.
𝑡𝑖𝑗ℎ𝑡 is the ad valorem tariff rate (using UNCTAD 1 methodology3) imposed by the
importing country 𝑖 against the import of product h from partner country j at time t. The
outcome equation incorporates the coefficients capturing the impacts of tariffs (𝛽1) and
non-tariff measures (𝛽2𝑛, 𝛽2𝑛′𝑖) on imports, where 𝛽2𝑛′𝑖 measures the importer-specific
impact of one NTM type under consideration, while 𝛽2𝑛 represents the effects of all
other NTM types, which we control for. It is the collection of all importer-specific
coefficients 𝛽2𝑛′𝑖 for all NTM types, which will eventually be transformed to importer-
specific AVEs per NTM type. 𝑁𝑇𝑀𝑛𝑖𝑗ℎ𝑡 are count variables for the NTM types described
earlier, i.e. they show the cumulative number of NTM regulations in force.4 In order to
obtain importer-specific AVEs of NTMs, we interact NTM variables with importer
country dummies 𝜔𝑖.
𝐶𝑖𝑗𝑡 captures country-pair characteristics and consists of classical gravity variables and
factor endowments. Gravity variables that enter our regressions are dummy variables
indicating whether they (i) are both EU members and/or WTO members, (ii) are
3 UNCTAD/WTO (2012) 4 The I-TIP data base reports on the date of withdrawal for ADP and CV measures. For other NTM types this
information is not available. For our analysis, we assume that they have not been withdrawn since.

neighbouring countries, (iii) share a common language, (iv) exhibit a common colonial
history, (v) belong to the same country (such as Hong Kong to China), or (vi) are
members of a Preferential Trade Agreement (PTA). The distance between the capital
cities of the trading countries enter in natural logs. These classical gravity variables are
further supplemented by measures of factor endowments. Following Baltagi et al.
(2003) and Ghodsi (2015c) we employ an index ranging from 0 to 0.5 depicting how
different the trading partners are with respect to real GDP per capita, shown in equation
(3). To account for the traditional market potential, we also include the sum of the
trading partners’ GDP at PPP in (4). Furthermore, we consider the distance between the
trading partners with respect to three factor endowments (relative to GDP) in (5),
namely labour L, capital stock K, and agricultural land area Al.

𝜔𝑖, 𝜔𝑗 , and 𝜔𝑡 in (2) are respectively importer, exporter, and time fixed effects, which
are employed using a Fixed Effect Estimator (FEE) and time-dummies. Moreover, robust
estimator clustering by country-pair-product is used to control for the shocks resulting
in a heteroskedastic error term 𝜇𝑖𝑗ℎ𝑡.
In a final step, AVEs are obtained by differentiating our import equation (2) with
respect to each NTM type. The impact of NTMs on import quantities can be decomposed,
as shown in equation (6), into (i) the impact of prices on import quantities, i.e. import
demand elasticities, estimated previously by Ghodsi and Stehrer (2015) and (ii) the
impact of NTMs on prices, i.e. the AVEs of NTMs.

period of analysis. In this paper we exclude Giffen goods, i.e. products, for which import
demand increases as prices increase, implying 𝜀𝑖ℎ > 0. Solving for AVEs and rearranging

At the heart of our dataset are the NTM notifications to the WTO provided via the WTO
I-TIP database, complemented by Ghodsi et al. (2015a) by imputing a large number of
HS 6-digit product codes for two thirds of the notifications with missing HS codes.
10
Import data was taken from the Commodity Trade Statistics Database (COMTRADE) and
was complemented by the Trade Analysis Information System (TRAINS) database. We
consider ad valorem tariffs at the HS 6-digit level from TRAINS and the WTO Integrated
Data Base (IDB) provided by the World Integrated Trade Solutions (WITS) platform. The
data gathering on tariffs followed a three-step choice rule: Whenever available,
preferential rates were considered. When this information was not given or not
applicable, the most-favoured-nation tariff rates entered our set. Lastly, we used data on
the effectively applied tariff rates. Data on factor endowments (labour force and capital
stock) as well as GDP was retrieved from the Penn World Tables (PWT 8.0); see
Feenstra et al. (2013 and 2015). The latest update of the PWT includes data for 2011,
which constrains our analysis to the period 2002 to 2011. Real GDP per capita at
chained PPP in 2005 USD was used for the computation of the similarity index and for
representing the traditional market (demand) potential. Information on agricultural
land was taken from the World Development Indicators database (WDI) of the World
Bank. CEPII provides data on commonly used gravity variables as mentioned above.
Finally, we borrow a data compilation for Preferential Trade Agreements (PTAs) as
reported by the WTO.
4. Empirical Results
We considered two different samples for our analysis. The first sample includes all
bilateral import flows of all countries covered by the WTO I-TIP database. The second
sample excludes intra-EU trade flows. The reason is that we do observe the number of
imposed NTMs per country, but not the degree of heterogeneity in terms of quality of
NTMs. As we expect a higher degree of homogeneity of NTMs addressing imports across
the EU, including intra-EU trade and therefore a higher number of similar NTMs would
lead to a downward bias in our AVE estimation results.
Considering the full sample, i.e. 5,221 products at the HS 6-digit level and 118
importers, our investigation results in 259,721 importer-product observations, for
which at least one NTM notification applied between 2002 and 2011. On average, each
product was imported by 57 importers, with a minimum of one importer, namely China,
for product HS 860620 (insulated or refrigerated railway or tramway freight cars) and a
maximum of 104 importers for product HS 040700 (birds’ eggs in shell). Furthermore,
countries in the sample targeted on average 3,542 imported products with NTMs. The
maximum number of products (5,154) was found for the US, and a minimum of only one
NTM-affected product, namely Chili Sauce, is reported for Cambodia.
We dealt with extreme values and potential outliers in two steps: First, we dropped the
tails of the distribution, by defining the maximum (minimum) values as those values
three times the interquartile distance above (below) the third (first) quartile of the
distribution, i.e. we specify the possible set of AVEs by the interval [Q1-3×IQ;Q3+3×IQ].
Second, we defined the lower bound for negative AVEs at -100%. The rationale behind it
is that the price of a product can only be reduced by a maximum of 100%. Therefore, we
replaced all AVEs smaller than -100% by this lower bound.

We can observe, first, that the total number of importer-product specific AVEs is
reduced by about 7% if we exclude intra-EU trade. Yet, the number of AVEs significantly
different from zero for SPS measures and TBTs increases. This confirms our concern,
that including a greater proportion of similar NTMs through the inclusion of intra-EU
trade reduces the number of AVEs for which a significant impact on imports could be
computed. Henceforth, we therefore focus on the analysis of AVEs excluding intra-EU
trade. Second, our AVE results are dominated by TBTs, for which we could compute as
many importer-product specific AVEs as for all other NTMs taken together. Third, we
find negative signs (that is a import promoting effect) for antidumping measures and
countervailing duties, as well as for specific trade concerns raised at the TBT committee.
As for the counteracting measures, a negative effect could be explained either by quality

adjustments of the exporter following the measure6 or by the possibility that we capture
the preceding excess import influx (e.g. through dumping practices) and not the effect of
the counteracting measure. By contrast, AVEs computed for all other NTM types show
positive mean and median values, pointing towards import impeding effects of NTMs.
In order to derive policy implications we continue our analysis by exploring AVEs by
importer (location and income) and by product (HS and BEC).
4.2. AVEs by importer
Different countries apply different types of NTMs. But even the same NTM type can
have an import promoting effect for one country and an import impeding effect for
another, which is on the one hand influenced by the product mix that it imports, and on
the other hand by the purpose and quality of the NTM measure imposed. In the
following, we summarise AVEs for countervailing duties and (special) safeguards under
the heading ‘other counteracting measures’ (OCA) and aggregate AVEs for specific trade
concerns on SPS measures or TBTs under the term STC.
As SPS measures and TBTs are the predominant NTMs in our data and form the heart
of ongoing political discussions, specifically with respect to the formation of deep mega-
regional trade agreements such as TTIP and TPP, we first restrict our attention to the
analysis of AVEs computed for these two measures. Figure 4 displays the import-
weighted (i.w.) AVEs7 for SPS measures and TBTs (summed up to one figure) for 98
countries on a world map. It shows the limitations that data availability poses on our
analysis, with countries for which we cannot report AVEs of SPS measures and TBTs
dyed in light yellow. Many countries in the north and east of Africa as well as in West
and Central Asia are either not members of the WTO, or hold only observer status, such
that we do not have information on NTMs imposed. In addition, there are WTO member
states in the south and west of Africa – including big countries, such as Angola, Chad,
Mauritania, Namibia, and Niger– for which we do not have sufficient information on
whether they do not apply NTMs or do not report applied NTMs. For Russia, data on SPS
measures and TBTs is only available from 2012 onwards, i.e. starting with the year of its
accession to the WTO. Countries for which we were able to calculate AVEs for SPS
measures and TBTs are coloured in blue, with a darker shading indicating stronger trade
restrictiveness. Considering the sum of import-weighted AVEs for SPS measures and
TBTs, as shown in Figure 4, we find the highest import restrictions for Ecuador, Vietnam,
Luxembourg, Tunisia and Mauritius. Romania and Latvia, too, feature among the Top 10.
Yet, the majority of EU members are found halfway down the list. On the other end we
find Croatia, Bahrain, Italy, the Slovak Republic and Australia, closely followed by
Germany.
6 Ghodsi et al. (2015b) argue that ADP measures induce exporters to downgrade the quality of their products and also
to increase prices to comply with the regulation. This quality downgrade makes the low price more appropriate in the domestic market imposing ADP, which would consequently increase the export to that market.

products, for which at least one AVE could be computed. [Using total imports instead would imply that we wrongly assumed that NTMs for which we were not able to compute AVEs were ineffective, i.e. show AVEs equal to zero.]
13
Figure 4: Import-weighted binding AVEs (at 10%) of SPS measures and TBTs
Overall, trade-weighted AVEs result in 48 countries showing import promoting and
49 countries showing import restricting effects. However, if NTMs are indeed trade
barriers they would naturally reduce imports. Consequently, using import values as
weights for AVEs we likely underestimate the import impeding effects of the use of
NTMs. Calculating importer-specific AVEs by using the simple average over all products,
69 countries show import impeding effects and only 29 countries are left showing
overall trade enhancing effects of SPS measures and TBTs.8 Yet, imposing no weight on
evaluated AVEs does not account for existing import structures of economies and
overemphasise the importance of AVEs for certain products. The truth will lie
somewhere in between.
Table 2 shows the mean values calculated as simple averages over all country-specific
AVEs, once for all results and once for binding NTMs, i.e. AVEs statistically impacting
imports at the 10% significance level. It clearly shows that, first, using import-weights
more strongly emphasises import promoting effects and second, considering only
binding NTMs shifts the distribution of AVEs to the right, i.e. towards more trade
restrictiveness or less trade promotion (with the exception of ADP).

from 1 to 28, with 1 indicating the highest AVEs and 28 representing the lowest AVEs,
we find that the rankings are very similar when using simple averages over all products,
or when computing simple averages only over products significantly affected by AVEs.
In these two cases, “new” EU member states appear more trade restrictive, with Latvia,
Malta, Romania, Lithuania and Hungary being ranked in the Top 5, while the Bottom 5 is
formed by “old” EU member states, namely Germany, Italy, Austria, France and Spain. If
we impose import weights, we still find Latvia and Romania among the Top 5, however,
Luxembourg appears as the most import restrictive country with respect to TBTs. At the
end of the list, we again find Germany, Italy and France. Yet, Austria, Spain and Portugal
drift to the centre, with Croatia, Denmark and the Slovak Republic taking their place.

How do these results feed into a global picture? In order to evaluate the global impact
of NTMs, we aggregate our country-based AVE results according to their regional
affiliation as laid out in the list of economies provided by the World Bank. Results are

The upper panel of Table 4 can be regarded as the upper bound of the import
restrictiveness of AVEs, as it shows results if we calculate the simple average over all
country-specific AVEs, which by themselves constitute simple averages over all traded
HS 6-digit products. It shows that SPS measures are on average hampering trade in
every region, with effects of SPS measures comparable to a 31% tariff rate in Sub-
Saharan Africa. By contrast, AVEs of TBTs are smaller in magnitude and even show
negative signs, i.e. trade enhancing effects, for North America and South Asia.
Europe and Central Asia as well as the Middle East and North Africa show high import
hampering AVEs for quantitative restrictions. Indeed, considering SPS measures, TBTs
and QRS, 7 (11) EU member countries features among the Top 10 (Top 20). The
unexpectedly high (and somewhat counterintuitive) negative value for QRS for Latin
America and the Caribbean is attributable to Peru and Costa Rica. They are the only two
countries out of 20 for the Latin American and Caribbean region for which we report
AVEs for quantitative restrictions, which are based on 6 and 18 measures reported to
the WTO between 1995 and 2011, respectively, – including prohibitions, non-automatic
16
licensing and ‘prohibitions, except under defined conditions’. Measures other than SPS and
TBT therefore need to be treated with greater caution: On a country level, we report
binding AVEs of SPS measures and TBTs for 85 countries and 92 countries, respectively.
Other measures are very much limited to North America, Europe and East Asia. We find
binding AVEs for Antidumping and other counteracting measures for 54 and 53
countries, respectively and in addition binding AVEs for QRS for 36 countries.
If we consider the simple average over all import-weighed AVEs by country – as
presented in the second panel – import restricting effects of SPS measures prevail, still
led by Sub-Saharan Africa. Yet, on the side of TBTs we observe a shift towards import
promoting effects, with East Asia, North Africa and the Middle East being the only
regions showing on average import impeding effects of TBTs.
As countries within regions are of different sizes and economic powers, we calculated a
third panel in which we apply import weights for each country within a region. That is,
more emphasis is put on a few global players within each region, such as Brazil in Latin
America, South Africa in Sub-Saharan Africa, India in South Asia or China and Japan in
East Asia, in order to better grasp the current impact of NTMs on a global scale. Even in
this case, SPS measures are lowering imports in four out of seven world regions.
Although more than 50% of the total number of imposed NTMs is attributable to high
income countries, as we have previously seen from the descriptive statistics on the WTO
I-TIP data, Table 4 and Table 5 do not reveal that they are also the most trade restrictive
ones. Applying the income group classification of the World Bank, Table 5 shows that low
income countries appear to have by far the most restrictive SPS measures and TBTs in
place, while AVEs for other NTM types could not be computed. Upper middle income
countries seem to be more trade restrictive than lower middle income countries, while
the lowest AVEs can be found for high income countries. Yet, the latter stand out
regarding the restrictiveness of quantitative restrictions.

Here we need to place a word of caution: With our results on AVEs, we cover about
50% of middle income countries as specified by the World Bank, more than 60% of high
17
income countries but a mere fifth of low income countries.10 The composition of our
sample does thus not represent global income structures, which specifically has to be
kept in mind, when we employ import-weights.
Given its political importance, specifically with respect to multilateral negotiations, we
illustrate the linkages between income and (the effect of) NTMs by plotting the number
of SPS measures and TBTs imposed as well as their corresponding average AVEs against
GDP per capita in purchasing power parities (PPP) in Figure 5. The upper panel
summarises the number of NTMs per importer, calculated as the simple average over all
imported HS 6-digit products, while the lower panel plots the simple average AVEs.

Top and Bottom 5% of the distribution and countries whose income over the period 2002-2011 on average exceeds
40,000 international Dollars at PPP p.c. EU members are shown in orange.
Looking at the number of SPS measures and TBTs imposed, the impression is that the
number of NTMs first increases with income and then falls again. Note that we make use 10 A full list of countries in our sample, mapped to the income group classification of the World Bank can be found in

of log scaling, in order to better see dynamics among countries making little use of NTMs
so far. This means that jumps from one horizontal line to the next, e.g. from Pakistan to
Norway, or from Australia to the US, indicate a quintupling of NTMs. For EU member
countries (highlighted in orange), a clear tendency towards a higher number of NTMs
for richer countries is observable. Turning to the lower panel of the graph, showing
simple average AVEs by country, one might argue for a convergence trend. Poorer
countries show a wide range of AVEs from below -40 up to above 80. Yet, for countries
at around 30 thousand international dollars (in PPP), AVEs range only between about 0
and 2011. For EU members, we do observe a clear downward trend, yet, with most
countries showing on average positive AVEs.
Summing up, we find that using simple averages over all products, twice as many
countries show import hampering effects of SPS measures and TBTs than import
promoting effects. Focusing on binding AVEs increases the import restricting effect,
which, however, is scaled down dramatically, when employing import weights.
In addition, we observe the trend that richer countries make use of a higher number of
NTMs, while simultaneously we see a downward trend with respect to AVEs. Indeed, we
find the lowest AVEs for high income countries, which, however, show very high average
AVEs on quantitative restrictions. Both trends are particularly visible for members of
the EU, with “new” member states showing lower numbers of NTMs, but higher AVEs
associated to them.
4.3. AVEs by product
The question arises, which products are affected in which way. In this section we
therefore explore average AVEs for products at the HS 6-digit level, both at the
individual level as well as aggregated to 97 HS 2-digit groups and further to 21
HS sections. In addition, we make use of a correspondence table from HS to BEC for
WIOD12 to explore patterns along the types products with respect to their use as final
consumption goods, intermediate goods or goods contributing to gross fixed capital
formation.
Looking at the HS 6-digit product level, we do not find any agricultural product among
the top 10 products facing the highest import restricting effects of SPS and TBT
measures. Yet, we find that, considering the average over all countries, meat of goats
(HS 020450) lists among the top 10 products for which an import promoting AVE of SPS
measures was computed. Considering global imports as the basis for the computation of
import-weighted AVEs instead of computing averages over import-weighed Aves by
importer, we also find flat fish (HS 030219) and meat of poultry (HS 020724) among the
top 10. With respect to TBTs we find on average import promoting effects for dried
vegetables (HS 071233) and carcasses of lamb (HS 020410) when considering averages
11 At this stage, it is worth to recall that in general, one would expect lower AVEs for poorer countries, whose import
demand elasticities tend to be relatively elastic compared to richer countries, specifically for the agri-food sector (see Appendix for an illustration). This implies that in order to experience the same drop in imports, increases of prices need to be bigger in richer countries than in poorer ones.

19
over countries, and plants for pharmacy, perfume and insecticides (HS 121140) if we
consider total imports. Import impeding effects for agricultural products such as
vegetables (HS 071029) or frozen fish (HS 030345) can, however, be observed for
quantitative restrictions.
At the HS 2-digit level, the highest import-weighted binding AVE for SPS measures is
computed for cork and articles thereof (19.2, HS 45), closely followed by manufactures
of straw (17.6, HS 46) and raw hides and skins (15.5, HS15.5), and by far the lowest for
works of art (-15, HS 97). Two agricultural product groups, namely fish and crustaceans
(HS 03), and animal or vegetable fats and oils (HS 15) feature among the Top 5 product
groups with negative AVEs for SPS measures. On the side of TBTs, umbrellas (19.7,
HS 66) and ships and boats (19.1, HS 89) face the highest AVEs, while the effect of TBTs
in imports of works of art is comparable to a negative tariff of -25%. A full list of import-
weighted AVEs by NTM type and HS-2-digit product group can be found in the Appendix.
Figure 6 and Figure 7 show our results of binding AVEs. The former depicts the simple
average of HS 6-digit product AVEs for each HS section, while the latter presents results,
when we first apply import-weights by section for each importer and then average over
all importers. Figure 6 strongly points towards import restricting effects of NTMs,
especially of quantitative restrictions and SPS measures, while Figure 7 suggests an
import promoting effect, especially of TBTs, for many product categories. Works of arts,
for which high import promoting effects are observed, were dropped from the graphs.
Despite the very different look of these two figures, they have in common that they show
that although notifications of SPS measures and TBTs dominated in our database,
quantitative restrictions still appear to be of great concern.

Note: Excl. intra-EU trade.
In the context of ongoing TTIP negotiations, it is an interesting exercise to contrast EU
exports with product-specific US AVEs and vice versa as reported in Table 6 and Table 7.
We need to keep in mind, though, that we do not report bilateral AVEs here.
Consequently, we do only see average AVEs for the major products exported by the EU
and the US, and thus the general ‘import environment’ in the destination market for
these products.
We first observe that the product groups that appear as the most important for the EU
with respect to total exports (excluding intra-EU trade) also constitute the major
product groups for exports to the US. This is also true for US Exports to the EU, with the
exception of cereals (HS 10), which are ranked within the top 10 of worldwide US
exports, but ranked 35th among products exported to the EU. Second, we do not report
any US AVE of quantitative restrictions for the top 10 EU export products, but we do
report EU AVEs of quantitative restrictions for five of the ten most important export
products of the US, of which two are import restrictive (vehicles and plastics) and three
are import enhancing (nuclear reactors, organic chemicals, and pharmaceutical
products). By contrast, major products of EU exports throughout face AVEs of SPS
measures in the US, with eight out of ten facing import restrictive AVEs, while AVEs for
SPS measures in the EU were only computed for six products, with half of them facing
trade promoting AVEs. Turning to TBTs, we find very high US AVEs for the top 10 EU
export products – both on the import promoting as well as on the import impeding side
– ranging from -84 for pharmaceutical products to 43.4 for optical and photographic
products. On the side of the EU, AVEs of TBTs for top export products of the US are
throughout smaller than AVEs of SPS measures, with only one exception, i.e. a negative
AVE of -39.0 for pears and precious stones.

In order to assess the impact of AVEs along the production and supply chains, we
further break down our product level results into the broad economic categories (BEC).
We make use of a correspondence table from HS to BEC for WIOD that puts weights on
HS 6-digit products given their use (1) as intermediate goods (INT), (2) for final
consumption (FC), or (3) for gross fixed capital formation (GFCF). Take the example
from our sample of HS code 940540 comprising electric lamps and lighting fittings. Our
correspondence table suggests a 50% use as intermediate product, a 25% use for final
consumption and a 25% contribution to gross capital formation. Table 8 reports our
estimated binding AVEs per NTM type, split up by sector and the broad economic
categories. Simple averages, as shown in the first part of the table, refer to the mean of
AVEs over all products that (partly) belonged to one BEC category. Import-weighted
(i.w.) means – on the importer level and the global level – were derived by multiplying
22
imports by BEC-weights and summing up over each BEC category. We thereby account
for the average importance of specific HS 6-digit products within each product group
over all countries in our sample and for their importance in global trade.

What we learn from this analysis is that SPS measures and TBTs play a greater role for
the manufacturing sector. In addition, quantitative restrictions play a particularly
important role for imports of intermediates and final consumption goods in both
sectors. SPS measures appear trade restrictive for the manufacturing sector, but –
depending on the import weights – seem to exert a rather trade promoting effect in the
agricultural sector.
5. Conclusion
In this paper we calculate ad valorem equivalents (AVE) for different types of non-tariff
measures (NTMs) at the 6-digit product level of the Harmonised System for 103
importing countries over the period 2002-2011. For this purpose, we make use of
information on NTM notifications to the WTO provided via the WTO I-TIP database,
enhanced by Ghodsi et al (2015a) through matching of missing HS codes. We contribute
to the existing literature by distinguishing the effects of NTMs for several different types
of NTMs, with specific attention given to technical barriers to trade (TBT), sanitary and
phytosanitary measures (SPS) and quantitative restrictions. In addition, working with
this unique dataset allows evaluating the trade effects of NTMs by means of an intensity
23
measure, i.e. by counting how many NTMs a specific importing country imposed against
a trading partner for each product. Furthermore, acknowledging the potential of NTMs
to reduce information asymmetries, effects of NTMs on imports are not restricted to be
negative in our analysis.
SPS measures and TBTs are found to both impede as well as promote trade, depending
on the NTM imposing country and product under consideration. However, despite the
political debate surrounding the upsurge in the number of SPS measures and TBTs
imposed during the past decade and their dominance in our database, the analysis
suggests that quantitative restrictions played an equally, if not more important, role in
restricting trade during the period under investigation.
While we find richer countries to apply more NTMs than poorer countries, we also
observe smaller effects of NTMs for richer countries compared to poorer countries. This
feature of increasing NTM notifications but decreasing AVEs for higher incomes is
particularly visible for members of the European Union. Lowest AVEs for SPS measures
and TBTs were calculated for high income countries, for which, however, we find very
high average AVEs of quantitative restrictions.
At the product level, we cannot confirm findings of previous studies, which indicated
that especially agricultural products are negatively affected by NTMs. Instead, we find
some agricultural products among those that experienced import boosts from SPS
measures and TBTs. Yet, they faced the highest AVEs stemming from quantitative
restrictions.
Splitting up products according to their purpose of use, we find that TBTs as well as
SPS measures play a more important role for the manufacturing sector, especially for
intermediate goods. Quantitative restrictions, by contrast, show strong import
restricting effects, predominantly for intermediates.
Although we find evidence for import promoting effects of NTMs, it has to be kept in
mind, that our computed AVEs are importer-product specific and not bilateral-product
specific. On the one hand, a negative AVE could imply, that the imposed NTM was import
promoting for all exporting countries. On the other hand, it could also imply that the
imposition of NTMs leads to some trade diversions, outweighing the trade reductions of
the affected exporter. Considering an exporter whose domestic standards and
regulations are closer to those of the NTM imposing country, the NTM should have
import promoting effects for this specific exporter, while for other exporters, it might
reduce the trade flows to the imposing country.
