K) Studies exploring the relationship between trade and economic growth suggest that countries
that adopt a more open stance toward international trade enjoy higher growth rates than those that
close their economies to trade.
HECKSCHER-OHLIN THEORY
A) Hecksher and Ohlin argued that comparative advantage arises from differences in national
factor endowments (land, labor, and capital). As a result, the Heckscher-Ohlin theory predicts
that countries will export goods that make intensive use of those factors that are locally abundant,
while importing goods that make intensive use of factors that are locally scarce.

The Leontief Paradox
B) Using the Heckscher-Ohlin theory, Leontief, in 1953 postulated that since the United States was
relatively abundant in capital compared to other nations, the United States would be an exporter of
capital intensive goods and an importer of labor-intensive goods. To his surprise, however, he
found that U.S. exports were less capital intensive than U.S. imports. Since this result was at
variance with the predictions of the theory, it has become know as the Leontief Paradox.

C) Recent research suggests that the Heckscher-Ohlin theory gains predictive power if the impact
of differences in technology on productivity is controlled for.
THE PRODUCT LIFE CYCLE THEORY
A) Raymond Vernon initially proposed the product life-cycle theory in the mid-1960s. According
to the theory as products mature both the location of sales and the optimal production location will
change affecting the flow and direction of trade.
B) According to Vernon, early in the life cycle of a typical new product, while demand is starting
to grow in the United States, demand in other advanced countries is limited to high-income groups.
The limited initial demand in other advanced countries does not make it worthwhile for firms in
those countries to start producing the new product, but it does necessitate some exports from the
United States to those countries. Over time, however, demand for the new product starts to grow
in other advanced countries. As it does, it becomes beneficial for foreign producers to begin
producing for their home markets. In addition, U.S. firms might set up production facilities in
those advanced countries where demand is growing. Consequently, production within other
advanced countries begins to limit the potential for exports from the United States.
