1. One major argument favoring the expansion of
U.S. business is that the sheer size of the global
market (6.9 billion people) is too large to ignore.
Plus it’s difficult for an economy, even one as
large as the U.S. economy, to produce all the goods
and services its citizens desire.
2. Comparative advantage theory was proposed by
David Ricardo and simply states that a country
should sell to other countries those products it pro-
duces most effectively and efficiently, and buy
from other countries those products it cannot pro-
duce as effectively and efficiently. Examples in-
clude the U.S. producing goods and services such
as software and engineering services and buying
goods, such as coffee and shoes, from other na-
tions.
3. The balance of trade is the difference in the total
value of a nation’s exports compared to its imports.
The balance of payments is the difference between
money coming into a country (from exports) and
money leaving the country (for imports) plus mon-
ey flows coming into or leaving a country from
other factors such as tourism, foreign aid, military
expenditures, and foreign investment.
