Suppose there are only two countries in our world – Zooland (we can call it ‘Z’ for short) and Ecotopia (we can call it ‘E’ for short). Zooland and Ecotopia both have the ability to produce two goods, widgets and sandals. In a year Zooland can produce 100 widgets OR 500 sandals while Ecotopia can produce either 150 widgets OR 400 sandals.

Draw the Production Possibility Curves which represents the above information.
If they were to specialise in the production of one good over the other, in which good should each country specialise? Explain.
Assume currently each country spends half the year producing widgets and half the year producing sandals – would specialising and trading help both of these countries? Explain.
Graphically represent your answer from (c).

Expert Solution

The production possibility curves of both economies is shown below

A is the point of initial consumption and production.

B is the point of consumption and production before trade.

Zooland can produce either 100 widgets or 500 sandals. So the opportunity cost to produce one widget is 5 sandals and 1 sandal is 1/5 widget

Similarly ecotopia can produce either 150 widget or 400 sandal. So the opportunity cost to produce one widget is 2.67 sandal and 1 sandal is 0.375 widget

Hence the opportunity cost or produce widget is less in ecotopia and of sandal is less in zooland so Zooland will produce sandal and Ecotopia will produce widget.

If they both produce the goods as said, then Zooland would produce 500 sandals and Ecotopia will produce 150 widgets.

When they trade , it would be anywhere between 1 widget for 2.67 to 5 sandal.

So here the ratio taken is 1:4. If Ecotopia exports 60 widgets in exchange of 240 sandals, then Ecotopia would have 90 widgets and 240 sandals and Zooland would have 60 widgets and 260 sandals. Both would be better off. This is shown in the graph of the PPCs where C and D are the points of consumption after trade.

Specialising would help both the countries.

Suppose there are only two countries in our world – Z and E. Country Z and E both have the ability to produce two goods, wire and sand. In a year Z can produce 100 wire OR 500 sand while E can produce either 150 wire OR 400 sand. Assume currently each country spends half the year producing wire and half the year producing sand – would specialising and trading help both of these countries? Explain.

Suppose there are only two countries in our world Australia and New Zealand. In a year Australia can produce 100 Sheep or 500 BBQs while New Zealand can produce either 150 Sheep or 400 BBQs. What is the PPC curve? If they were to specialise who would and in what BBQs or Sheep? If both countries were to spend half the year producing each of their products- explain how specialization and trade would benefit each?

EXERCISE 18.5 COMPARATIVE ADVANTAGE Suppose that there are only two countries in the world, Germany and Turkey, each with four workers. Within a given time period, each worker in Germany can produce three cars or two televisions, and each worker in Turkey can produce two cars or three televisions.

Suppose there are only two oil producing countries in the world and who compete with one...

Suppose there are only two oil producing countries in the world and who compete with one another: Canada and Norway. The world inverse demand for oil is given by P(Q) = 180 ? qC ? qN where qC and qN are the quantities of oil brought to market by Canada and Norway, respectively. The cost function for extracting oil is identical across both countries and equal to C(q) = 60q. The two countries engage in Cournot competition by choosing how...

Assume that there are only two countries in the world, Atlantica and Pacifica. Both countries produce and consume surfboards. The pre-trade equilibrium price of surfboards in Atlantica is $300 and the pre-trade price of surfboards in Pacifica is $400. a) Draw a three-graph diagram to depict the Pacifica, Atlantica, and international markets for surfboards. Assume that free trade opens up between Pacifica and Atlantica yielding an international price of $375 with 10,000 surfboards being traded. Be sure to label all...

There are two countries, England and USA, in a world where there are only two factors of production, land and labor. England has 8 million acres of land and 2 million workers while USA has 5 million acres of land and 1 million workers. Both countries produce two goods, cars and watches, using identical technology. Per acre of land, the production of cars requires 4 workers while the production of watches requires 1 worker. Using a PPF/indifference curve graph, illustrate...
