Assume that transportation costs are especially high for Widgets in the two-country, two-product Ricardian model, and Country A enjoys a comparative advantage in Widgets, then A) country B must also enjoy a comparative advantage in Widgets. B) country B may end up exporting Widgets. C) country A may switch to having a comparative advantage in the other good. D) country A will still export Widgets. E) trade may be impossible between the two countries.

D

Explanation:

A country has comparative advantage in production if it produces at a lower opportunity cost when compared to other countries. A country would export the good for which it has a comparative advantage and import the good for which it doesn't have a comparative advantage

For example, country A produces 10kg of beans and 5kg of rice. Country B produces 5kg of beans and 10kg of rice.  

for country A,  

opportunity cost of producing beans = 5/10 = 0.5

opportunity cost of producing rice = 10/5 = 2

for country B,  

opportunity cost of producing rice = 5/10 = 0.5

opportunity cost of producing beans = 10/5 = 2

Country A has a comparative advantage in the production of beans and country B has a comparative advantage in the production of rice

Country A would export beans to country B and B would export rice to A

1   all nations face the problem of scarcity because there are limited resources and unlimited wants. nations do not have enough factors of production to produce everything that their population wants. entrepreneurial resources initiate businesses to make new goods and services; labor resources produce goods and services.

2 there are four factors of production: natural resources, labor resources, capital resources, and entrepreneurial resources. natural resources are raw materials from nature that are used to produce goods. trees, water, and grains are natural resources. some natural resources, such as wheat and cattle, are renewable
