IV. The Mexico– U.S. trade example continues to illustrate the gains from trade.
Gains from trade are made up of gains from exchange plus gains from specu-
lation. Trade also confers four other signi cant bene ts. First, trade exposes
domestic rms to competition. Second, trade often embodies new technolo–
gies that raise productivity. Third, trade increases not only the quantity of
goods available for consumption, but also the quality and variety of goods
obtainable. Fourth, trade brings people into contact with one another.
V. Many low– and middle- income nations have resources that are in high demand
from high- income nations. Focusing on the trade of primary products is an
engine for growth for many nations. Additional factors of production, such
as capital and labor, can be gained from the expansion of primary product
exports. Also, primary product exports present the possibility of stimulating
other, related sectors, which leads to the possibility of forward linkages.
VI. Raul Prebisch, Hans Singer, and other economists generated the idea of
export pessimism, referring to the decrease of primary commodity exports
relative to prices of manufactured goods over the long run. Relative price
movements were traced to structural factors in the global economy, including
Engel’s law, technological changes in manufacturing, and the notion of mar–
ket power and competition in developed countries. In terms of trends, the
decline of prices of nonfuel commodities over the past 50 years and the uc-
tuation in commodity prices are two apparent trends this chapter illustrates.
VII. Problems with primary product exports are often fatal to development aspi-
rations. Dutch disease is the issue that emerging economies could face when
experiencing export booms of primary commodities. Keys to understand–
ing this paradox are the nominal exchange rate, real exchange rate, and the
prices of tradable and nontradable goods. This chapter goes into great detail
on the relationships between these concepts.
VIII. Resource traps are explained in detail with reference to Paul Collier, author
of The Bottom Billion. He identi es several traps that prevent nations from
growing. Problems such as commodity price cycles and macroeconomic
mismanagement are often caused by poor governance and corruption acts
like a tax on economic activity. It is possible to escape these problems and
overcome the resource curse, though. The use of sovereign wealth funds
and adoption of international charters such as the Extractive Industries
Transparency Initiative (EITI) are current approaches being used.
