tons of

rice

bushels of

wheat,

while in

Mexico ,

an acre of land can produce

tons of

rice

bushels of

twheat.

Which of the following statements are true? (Select all that apply)

Sri Lanka

has an absolute advantage in the production of

rice

because it has higher productivity in

rice.

Mexico

has an absolute advantage in the production of

rice

because it has higher productivity in

rice.

Sri Lanka

has an absolute advantage in the production of

wheat

because it has higher productivity in

wheat.

Mexico

has an absolute advantage in the production of

wheat

because it has higher productivity in

wheat.

Which of the following statements is true of comparative advantage?

A country has a comparative advantage if it can produce less units of a good per hour than other countries.

A country has a comparative advantage in the production of a good if it has a lower opportunity cost of producing that good.

A country has a comparative advantage if it can produce more units of a good per hour than other countries.

A country has a comparative advantage in the production of a good if it has a higher opportunity cost of producing that good.

Sri Lanka has a comparative advantage in the production of

▼

a. rice

b. wheat

, while

Mexico

has a comparative advantage in the production of

▼

a. wheat

b. rice

Suppose

Mexican scientists

have developed a groundbreaking new technology that increases the productivity of

rice

Mexico

tons of

rice

per acre (and has no effect on

Mexican wheat productivity

or Sri Lanka's productivity in wheat or rice.

Given this information, the new technology will have

▼

a. no effect on Sri Lanka's comparative advantage in rice

b. an effect on Sri Lanka's comparative advantage in rice

Solutions

Expert Solution

A. Sri Lanka has an absolute advantage in the production of rice because it has higher productivity in rice.
D. Mexico has an absolute advantage in the production of wheat because it has higher productivity in wheat.
(As Sri Lanka can produce per rice per acre and Mexico can produce more wheat per acre so their absolute advantage lies in these products.)

Sri Lanka has a comparative advantage in the production of a. rice
Mexico has a comparative advantage in the production of a. wheat

(Opportunity cost of 1 ton of rice in Sri Lanka = Total wheat given up/Total rice produced = 20/45 = 0.44 bushel of wheat
Opportunity cost of 1 ton of rice in Mexico = Total wheat given up/Total rice produced = 40/30 = 1.33 bushel of wheat
So, Sri Lanka has comparative advantage in the production of rice as its opportunity cost is lower and thereby Mexico will have comparative advantage in the production of wheat.)

a. a. no effect on Sri Lanka's comparative advantage in rice
(Opportunity cost of 1 ton of rice in Mexico = Total wheat given up/Total rice produced = 40/60 = 0.5 bushel of wheat. Still, opportunity cost of 1 tons of rice is lower in Sri Lanka so there is no effect on Sri Lanka's comparative advantage in rice.)

Consider two countries: Canada and Sri Lanka. Assume that each can produce only two goods: maple syrup and jaggery. In a single year, Canada can produce 250,000 tons of maple syrup, or 90,000 tons of jaggery. In the same period of time, Sri Lanka can produce 1,000 tons of maple syrup, or 70,000 tons of jaggery. Suppose that both nations are initially in a state of autarky. If Canada were to produce 170,000 tons of maple syrup and 36,000 tons...

Comparative Advantage There are two countries in the world. There are also only two different types of goods produced, food and clothing. Each country has the same amount of “inputs” (i.e. labor, capital, raw materials, etc.), which amounts to 100,000 units of input. Below is a chart that lists out how many units of output each country could create if they created just one type of good. For example, if Country A produced ONLY food, then with 100,000 units of...
