1. figures 1-2 and 1-7 rely on data from the year 2006, and figure 1-6
relies on data from 2005, to map worldwide trade, migration, and
foreign direct investment. up- dated data for migration and foreign
direct investment were not available at the time of writing this chapter,
but are available for worldwide trade. in this question you are asked to
update the numbers for world trade shown in table 1-1.
a. go to the world trade organization website at www. wto. org and look
for their trade data under ―resources‖ and ―statistics.‖1 look for the
most recent edition of their international trade statistics publication,
then go to ―trade by region‖ and find the excel spreadsheet with ―intra-
and inter-regional merchandise trade.‖ print out this table. if you
cannot find the website or spreadsheet, use the 2005 table for ―in- tra-
and inter-regional merchandise trade,‖ which is printed below:

, c. what is the total amount of trade (in either direction) between
europe and north america? add that to the total trade within europe,
and calculate the per- centage of this to the world total.
ANS: $(369 + 475) = $844 billion. adding that to intra-european
trade, we obtain 35. 2% of the world total.
d. what is the total amount of trade within the americas (i. e. , between
north america, central america, south america, and within each of
these regions)? what percentage is this of total world trade?
ANS: $(1,015 + 165 + 169 + 159) = $1,508 billion, or 9. 6% of the
world total
e. what is the total value of exports from europe and the americas and
what per- centage is this of the world total?
ANS: $(2,036 + 600 + 6,447) = $8,983 billion, or 57. 8% of the world total
f. what is the total value of exports from asia, and what percentage is
this of the world total?
ANS: $4,353 billion, which is 27. 7% of the world total
g. what is the total value of exports from the middle east and the
commonwealth of independent states2 and what percentage is this
of the world total?
ANS: $(1,021 + 703) = $1,724 billion, which is 11% of the world total
h. what is the total value of exports from africa, and what percentage is
this of the world total?
ANS: $298 billion, which is 3. 5% of the world total
i. how do your answers to (b) through (h) compare with the shares of
worldwide trade shown in table 1-1?
ANS: the shares computed in (b) through (h) are quite similar to
table 1. 1. both are within one percentage point of table 1-1.
2. the quotation from federal reserve chairman ben bernanke at the
beginning of the chapter is from a speech that he presented in jackson
hole,wyoming, on august 25, 2006, entitled ―global economic integration:
what‘s new and what‘s not?‖ the full transcript of the speech is
available at http://www/federalreserve. gov/
newsevents/speech/bernanke20060825a. htm. read this speech and
answer the fol- lowing questions:
a. list three ways in which international trade today is not that
different from the trade that occurred before world war i.
ANS:
i) physical distance is the same.
ii) new transportation methods allow for more trade.
iii) governments foster open trade, as well as financial flows.
iv) some groups are opposed to free trade.
v) the range of goods that are tradable has broadened.
b. list three ways in which international trade today does differ from
the trade that occurred before world war i.
ANS:
i) intra-industry trade has increased.

the commonwealth of independent states consists of: azerbaijan, armenia, belarus, georgia, kazakhstan,
kyrgyzstan, moldova, russia, tajikistan, turkmenistan, uzbekistan, and ukraine.

, ii) information and communication technologies permit trade in services.
iii) scale and pace of growth in trade is faster.
iv) core-periphery pattern is no longer relevant.
v) fragmentation of production processes has occurred.
vi) capital markets are more mature, and gross flows are larger.
the ricardian model
1. at the beginning of the chapter there is a brief quotation from david
ricardo, and here is a longer version of what ricardo wrote:
england may be so circumstanced, that to produce the cloth may require the
labour of 100 men for 1 year; and if she attempted to make the wine, it might
require the labour of 120 men for the same time. to produce the wine in
portugal, might require only the
labour of 80 men for 1 year, and to produce the cloth in the same country,
might require the labour of 90 men for the same time. it would therefore be
advantageous for her to export wine in exchange for cloth. this exchange
might even take place, notwithstanding that the commodity imported by
portugal could be produced there with less labour than in england.
suppose that the amount of labor he describes can produce 1,000 yards
of cloth or 1,000 bottles of wine in either country. then answer the
following questions:
a. what is england‘s marginal product of labor in cloth and in wine,
and what is portugal‘s marginal product of labor in cloth and in
wine? which country has absolute advantage in cloth and in wine,
and why?
ANS: in england, 100 men produce 1,000 yards of cloth, so mplc =
= 10. 120 men produce 1,000 bottles of wine, so mplw =
= 8. 3. in portugal, 90 men produce 1,000 yards of cloth, so
mpl* = = 11. 1. 80 men produce 1,000 bottles of wine, so
mpl* = = 12. 5. so portugal has an absolute advantage in both cloth
and wine, because it has higher marginal products of labor in both
industries than does england.
