Outline of the Talk

• Integration of Trade• Disintegration of Production• China’s Current Trade Situation• Sino-U.S. Trade Relationship• Traditional Trade Theory• Current Research Topics

International Trade, Dr. Miaojie Yu, CCER, Fall 07

Integration of Trade

• How much do we trade?

• Trade still remains a seemingly small fraction of GDP for rich countries.

• The decades leading up to 1913 was a golden age of global trade and investment.

• The global integration of trade keeps the same level.

• Table 1 ( Feenstra, 1998)

The World Is More Integrated Than Ever

• Some facts are hidden. • Industrial countries have increasing shares of their economies

devoted to services rather than manufacturing.

• Make comparison from different views.• Should measure merchandise trade relative to merchandise

value-added. • Almost all countries have experienced substantial growth in

trade.• Table 2

How to Explain Growing Trade?

• Trade Liberalization– GATT/WTO

– Regional Trade Agreements: CUSFTA, NAFTA, CARICOM, CACM, MERCOSUR, ASEAN, SPARTECA.

• Falling Transportation Cost

• 2/5 trade growth can be explained by these two factors.

• When trading partners becomes more similar in size.

-- Example: World GDP=150; – Scenario 1: Country A= 100; country B=25, country C=25

– Scenario 2: Country A= 50; country B=50, country C=50

– Maximum exports are different.

International Trade, Dr. Miaojie Yu, CCER, Fall 07

Disintegration of Production

• Disintegration of production itself leads to more trade due, in large part, to the calculation method.

• Outsourcing• Barbie doll story (Tempest, 1996)

– Sell for about $10 in the U.S.– Made in Mainland China, but export from Hong Kong for $2– 65 cents cover materials cost, 35 cents pay for Chinese labor.– The remaining 1$ for transportation in China– The remaining 7$ for transportation, marketing, wholesaling and

retailing.– $1 for the Mattel.

International Trade, Dr. Miaojie Yu, CCER, Fall 07

Outsourcing

• First measurement: trade is categorized by the end-user.

• The U.S. trade shifts away from agriculture and raw materials, and towards manufactured goods in the U.S. trade.

• Processed manufactured goods play an increasing important role in U.S. trade.

• Outsourcing is important!

• U.S. firms have been substituting away from these processing activities at home.

Outsourcing on the value-chain

International Trade, Dr. Miaojie Yu, CCER, Fall 07

Another measurement: imported intermediate goods

International Trade, Dr. Miaojie Yu, CCER, Fall 07

The World is Flat

• Vertical specification : another name of Outsourcing

• U.S. has a doubling of the share of imported inputs between 1975 and 1995 for all manufacturing.

• The U.K. shows an especially large absolute increase in foreign outsourcing.

Trade Openness

International Trade, Dr. Miaojie Yu, CCER, Fall 07

China’s Current Trade Situation

• Current trade openness is around 64% of GDP.• China’s share in world trade has grown steadily since

1979.

International Trade, Dr. Miaojie Yu, CCER, Fall 07

China’s Trade

• China has increased its penetration into rich countries’ market.

International Trade, Dr. Miaojie Yu, CCER, Fall 07

China’s Trade

• Simultaneously, it also becomes a more important export destination.

International Trade, Dr. Miaojie Yu, CCER, Fall 07

China’s role in Asian Regional Trade

• China is now among the most important export destinations for other Asian economies

International Trade, Dr. Miaojie Yu, CCER, Fall 07

Strong Export Potential Forward in China

• China’s integration with the world economy so far is not unprecedented in either its scope or speed.

• Compared to Japan, Korea, and other NIEs in their fast development period, China’s exports have grown at a slower rate than theirs.

• This suggests that China could maintain relatively high strong export growth for years to come.

Composition of Trade

• Diversify from an initial heavy reliance on textile and other light manufacturing.

• In the early 1990s, exports profiles rank as follows: light manufacturing, textile, machinery and transport (small electronics).

• Today, China exports more sophisticated electronics, furniture, travel goods, and industrial supplies.

• Statistical indicators of dispersion illustrate an increase in overall export diversification.

International Trade, Dr. Miaojie Yu, CCER, Fall 07

International Trade, Dr. Miaojie Yu, CCER, Fall 07

Outsourcing in China

• A high degree of vertical specification of production within the Asia region.

• Evidence 1: The ratio of import for processing to total imports increased from 35% in the early 1990s to more than 50% today.

• One example• Evidence 2: Pattern of Trade• An increasing imports from Asia and a corresponding

increase in exports to the U.S. and Europe.

Trade Balance

• China keeps a modest overall trade surplus.

• China has significant trade surplus from trade with the U.S.

• But it was offset by an increasing trade deficit with the rest of Asia.

International Trade, Dr. Miaojie Yu, CCER, Fall 07

International Trade, Dr. Miaojie Yu, CCER, Fall 07

Sino-U.S. Bilateral Trade

• This year China reaches a $144 billion trade surplus with the U.S.

• Simultaneously, more than 3 million workers lost their jobs.

• Congressmen in the U.S. threat to perform trade sanction with China.—Impose 27.4% high tariffs.

• Push RMB revaluate strongly and quickly. • Pending the permanent most favored nation (MFN)

treatment.

International Trade, Dr. Miaojie Yu, CCER, Fall 07

Questions

• Economically speaking, is it deficit necessary bad for the deficit country, and good for the surplus country?

• Any essential link between the blue-worker unemployment and trade deficit?

• Is it credible for the U.S. congressional threat?

International Trade, Dr. Miaojie Yu, CCER, Fall 07

Trade Deficit is not necessarily bad!

• Check the basic trade identity:

Trade Deficit=Net Inflow of Foreign Capital

• Trade deficit is like borrowing money from foreigners.• The key point is how to use.• Investment or Consumption?• Historical stories in 1980s, 1990s, and 2000s.

International Trade, Dr. Miaojie Yu, CCER, Fall 07

Trade Surplus is not necessarily good!

• Statistically, it is good for GDP calculation.

• But GDP does not mean anything!

• Export Booming and Productivity Improvement– The termination of Multilateral Fiber Agreement (MFA) in 2005.

• Green GDP

International Trade, Dr. Miaojie Yu, CCER, Fall 07

The Far Cry from U.S. Workers

• Any essential link between the blue-worker unemployment and trade deficit?

• No.

• The elasticity of substitution between Chinese export and other Asian countries’ export is very high.

• The essential reason for huge unemployment is due to the economy recession in years 2001-2003 in the U.S.

International Trade, Dr. Miaojie Yu, CCER, Fall 07

The Congressional Threat

• It is incredible.

• The U.S. does not have any right to terminate our permanent MFN treatment.

• They don’t dare to uni-laterally impose high tariffs on Chinese textile and garments.– It violates the WTO principles.– It worse the U.S. itself due to the elasticity of exports and

imports.– It already gets historical lesson from the stupid policy.

International Trade, Dr. Miaojie Yu, CCER, Fall 07

What do we study in Trade?

• Gains from Trade– Each trading country gains– Within a country, some gain but some lose

• Pattern of Trade– Who trade with whom for what?– Inter-sectional v.s. intra-sectional trade

• Government Effect of Policy on Trade• Multinational Cooperation and Foreign Direct

Investment (FDI)

International Trade, Dr. Miaojie Yu, CCER, Fall 07
