ECON 3601 Lecture Notes - Lecture 2: Gross Domestic Product, Outsourcing, Offshoring
Lecture 1:
Who Trades with Whom?
• More than 30% of world output is sold across national borders.
• The 5 largest trading partners with the U.S. in 2012 were Canada, China, Mexico, Japan,
and Germany.
• The largest 15 trading partners with the
U.S. accounted for 69% of the value of U.S. trade in 2012.
Size Matters: The Gravity Model
• 3 of the top 10 trading partners with the U.S.
in 2012 were also the 3 largest European economies: Germany, the United Kingdom,
and France.
• Why does the United States trade more with these European countries than with
others?
– These countries have the largest gross domestic product (GDP), the value of
goods and services
produced in an economy, in Europe.
– Eah Euopea outy’s shae of U.“. tade ith Euope is oughly eual to its
share of European GDP.
• The size of an economy is directly related to the volume of imports and exports.
– Larger economies produce more goods and services, so they have more to sell in
the export market.
– Larger economies generate more income from
the goods and services sold, so they are able to buy more imports.
• Trade between any two countries is larger, the larger is either country.
• The gravity model assumes that size and distance are important for trade in the
following way:
Tij = A x Yi x Yj /Dij
where
Tij is the value of trade between country i and country j
A is a constant
Yi the GDP of country I, Yj is the GDP of country j
Dij is the distance between country i and country j
• Or more generally
Tij = A x Yia x Yjb /Dijc
where a, b, and c are allowed to differ from 1.
Using the Gravity Model: Looking for Anomalies
• A gravity model fits the data on U.S. trade with European countries well but not
perfectly.
• The Netherlands, Belgium and Ireland trade much more with the United States than
predicted by a gravity model.
– Ireland has strong cultural affinity due to common language and history of
migration.

Document Summary
U. s. accounted for 69% of the value of u. s. trade in 2012. These countries have the largest gross domestic product (gdp), the value of goods and services produced in an economy, in europe. Ea(cid:272)h eu(cid:396)opea(cid:374) (cid:272)ou(cid:374)t(cid:396)y"s sha(cid:396)e of u. t(cid:396)ade (cid:449)ith eu(cid:396)ope is (cid:396)oughly e(cid:395)ual to its share of european gdp: the size of an economy is directly related to the volume of imports and exports. Larger economies produce more goods and services, so they have more to sell in the export market. Tij = a x yi x yj /dij where. Tij is the value of trade between country i and country j. Yi the gdp of country i, yj is the gdp of country j. Dij is the distance between country i and country j: or more generally. Tij = a x yi where a, b, and c are allowed to differ from 1. Ireland has strong cultural affinity due to common language and history of migration.
