- International Data Classifications

- Applications
- 3.1 Forecasting
- 3.2 Potential Market Analysis
- 3.3 International Trade Analysis
31. International Trade Data Classifications
- Three commonly used classifications
- 1. Broad economic category (BEC)
- Equivalent to BEAs end-use category
- 2. Standard international trade classification
(SITC) - 3. Harmonized system (HS)
41. International Trade Data Classifications
(Continued)
- 1.1 Broad Economic Category (BEC)
51. International Trade Data Classifications
(Continued)
- 1.1 Broad Economic Category (BEC)
- The BEC was originally designed to serve as a
means for converting external trade data compiled
on the SITC into end-use categories that are
meaningful within the framework of the System of
National Accounts (SNA), namely categories
approximating the three basic classes of goods in
the SNA capital goods, intermediate goods and
consumption goods. Specifically, the
subcategories of the BEC can be aggregated to
approximate these three classes of goods.
61. International Trade Data Classifications
(Continued)
- This aggregation permits external trade
statistics to be considered jointly with other
sets of general economic statistics, such as
national accounts and industrial statistics, for
national, regional or world level economic
analysis.

81. International Trade Data Classifications
(Continued)
- 1.2 SITC
- SITC was developed by the UN with the intention
of classifying traded products not only on the
basis of their material and physical properties
and stage of processing but also their economic
functions in order to facilitate economic
analysis. - Rev. 1 from 1962,
- Rev. 2 from 1976,
- Rev. 3 from 1988, and
- Rev. 4 from 2007
91. International Trade Data Classifications
(Continued)
- Advantages
- Classifies all commodities into headings suitable
for economic analysis - Longer historical data
- Disadvantages
- Lack of newer products
101. International Trade Data Classifications
(Continued)
- Rev. 4 has
- 10 one-digit sections,
- 67 two-digit divisions,
- 262 three-digit groups,
- 1,023 four-digit groups, and
- 2,970 five-digit headings
111. International Trade Data Classifications
(Continued)
- SITCs 10 Sections
- 0 - Food and live animals1 - Beverages and
tobacco2 - Crude materials, inedible, except
fuels3 - Mineral fuels, lubricants and related
materials4 - Animal and vegetable oils, fats and
waxes5 - Chemicals and related products, nes6 -
Manufactured goods classified chiefly by
material7 - Machinery and transport equipment8
- Miscellaneous manufactured articles9 -
Commodities and transactions not classified
elsewhere in the SITC
121. International Trade Data Classifications
(Continued)
- 1.3 Harmonized System (HS)
- HS has a more precise breakdown of the products'
individual categories and is widely used by
customs authorities. - HS1988,
- HS1996,
- HS2002, and
- HS2007
- Has about 6,000 commodities

agency (see IMFs SDDS or GDDS websites) - EU countries, Japan, etc. are free. Others
cost as much as 10,000 per month. - Difficult to establish right contacts because
of language and technical problems - 2. IMF Direction of Trade Statistics

243. Applications (Continued)
- 3.1 Forecasting
- Analysis focuses on
- Exchange rate pass-through
- Relative price and income elasticities between
exports and imports
253. Applications (Continued)
- 3.2 Potential Market Analysis
- Use HS classification that gives commodity
details - Analysis focuses on market size or market share
263. Applications (Continued)
- 3.3 International Trade Analysis
- Use annual data in SITC for longer historical
data and HS for the latest periods - Analysis focuses on
- A. Exports
- Market share
- Export concentration as measured by Herfindahl
indices - Similarity
- Balassas revealed comparative advantage
- Export decomposition
273. Applications (Continued)
- B. Imports
- Import distribution
- Import concentration as measured by Herfindahl
indices - Shaw-Kilpatrick-Lees revealed symmetric import
concentration - C. Intra-industry Trade
- Grubel-Lloyd index
- Vona index
283. Applications (Continued)
- D. Overall International Trade Analysis
- Trade openness ratio
- Trade complementarity
- Shaw-Kilpatrick-Lees revealed symmetric
competitiveness index - Mirror trade data discrepancies as an indicator
for customs evasion - Cross-sectional unit price variation as an
indicator for trade-based laundering or customs
evasion
293. Applications (Continued)
- Question Does China compete with the US in the
world export markets? - We could address the question by
- Analyzing the degree of overlapping in top 40
commodities in exports - Examining similarity index (SI), 0 lt SI lt 100
- 0 not similar at all
- 100 identical export distribution
- Comparing revealed comparative advantages
303. Applications (Continued)
- Table 3 compares Chinese and US exports to the
world (the top 40 products) in terms of export
distribution at HS2002 6-digit level in 2006. It
is interesting to note that among the top 40
products (in terms of export distribution), only
11 products overlap.

323. Applications (Continued)
- Similarity index is defined by Finger and Kreinin
as - S(ab,c) ? Min X i (ac), X i (bc)
- 0 lt S(ab,c) lt 100
- Where
- S(ab,c) similarity between exports of
countries a and b to a
common market c - X i (ac) share of commodity i in as
exports to c X i (bc) share of commodity
i in bs exports to c -

343. Applications (Continued)
- Table 5 shows the similarity index between
Chinese and US exports at the HS2002 6-digit
level. The similarities between Chinas exports
to the world and US exports to the world were
also relatively low.

363. Applications (Continued)
- Revealed Comparative Advantage (RCA), developed
by Bela Balassa1 in his 1965 paper, is a commonly
used indicator to show (reveal) export
competitiveness - RCA of a commodity or sector is defined as a
countrys share in total world exports of that
commodity or sector relative to the countrys
overall share of world trade. - 1. Balassa, B. (1965), Trade Liberalization and
Revealed Comparative Advantage, The Manchester
School of Economic and Social Studies, Vol. 32,
pp. 99-123.
373. Applications (Continued)
- RCA ranges from 0 to infinity with 1 as the
break-even point. An RCA value of less than 1
means that the sector has no export comparative
advantage, while a value above 1 indicates that
the sector has a revealed comparative
advantage. However, RCA is not symmetrical in the
sense that one cannot compare both sides of the
break-even point.
383. Applications (Continued)
- Laursen2 modified RCA to make the indicator
symmetric, with the value ranging from -1 to 1
(zero is the break-even point). He named the
modified indicator Revealed Symmetric
Comparative Advantage (RSCA). - RSCA (RCA -1) / (RCA 1)

Advantage and the Alternatives as Measures of

403. Applications (Continued)
- Table 7 shows a symmetric version of Balassas
RCA. It clearly demonstrates that as of 2006,
China was still not competing with the US in the
same product space. There are 1,339 out of 5,225
6-digit commodities in which China and the US
both have RSCA gt 0, or 25.6 percent of the total.
Overall, the correlation between RSCAs for the
two countries is -0.40, suggesting that the two
countries are competitive (or uncompetitive) in
quite different commodities.
41(No Transcript)
423. Applications (Continued)
- Chinas comparative advantage as an exporter
still lies in relatively low value-added products
which require higher labor inputs. I should note
that compared to other exporting countries China
has not shown comparative advantage in high
value-added manufacturing products, but Chinas
export shares and RSCA values in this respect are
rising.
433. Applications (Continued)
- Question Does China compete with the US in the
world export markets? - Answer As of 2006, China was still not
competing with the US in the same product space,
but the overlapping product space is getting
bigger every year. -
