Economics Essay 1

ECON10120 – Economic Principles and Skills Student ID: 093238351 Why do countries trade with each other? Show, using examples, why this may be to do with the principle of comparative advantage? Why Do Countries Trade? Countries trade for a number of reasons: 1. Resources not available 2. Offsetting costs of imports 3. Improve Competition 4. More money in the economy 5. Make relations with other countries. 6. Opportunity costs/Specialization 7. Absolute Advantage 8. Comparative Advantage One of them is simply the good cannot be made in the countries due to the weather for example, may be too cold to grow bananas and similar goods. The government may need to offset the cost of importing goods into the country by exporting goods in which the country specializes itself for the benefit and revenue of other countries. This may also help in reducing surpluses in a market or resolve shortages. Imports and exports will also improve the competition within a nation. Costs of production and prices will have to be kept lower so that demand will remain for their good that is produced in Country A as well as costs to continue making a product and become innovative, which will benefit the government, aggregate demand and the consumers happiness. Exports benefit the country through the circular flow of income and more money from abroad enters the country and lowers the price of the currency to make them more internationally price competitive. This will also lead to the Multiplier Effect. The Multiplier Effect is defined as: The multiplier effect occurs when a change in aggregate demand causes a further change in aggregate output for the economy. To illustrate more plainly with an example: if a company spends $1 million to build a factory employing 100 new workers, those workers will require infrastructure like housing, gas stations, a grocery store, and so forth, which will in turn employ other workers who require the same services; to pick a number, say that all of these workers will spend $2 million per year on consumables, which represent "increased aggregate output" from the economy. Since there was an initial $1 million input which created a $2 million output, the multiplier is 2. Sometimes there may be a need to trade so that stable relations can be made with other countries that may have fallen out with each other and are looking to resolve the conflict without resulting in war, or may begin to start new relations with a country. There is also the opportunity cost and specialization of producing goods that the country cannot produce themselves that well, a theoretical example would be the production of crop 1 in Country A is hard to make because of the weather, available resources and manpower. This then takes up the resources that could be used to make crop 2.

As we can see from the graph of country A’s production possibility frontier (PPF) if they specialized in Crop 1 they would have 20 units of it, whereas Crop 2 only has 10 units made if it was specialized in. Indirectly this will help the work force, as they will have less demanding work to complete as they can make double what they were before so for half the effort they can still produce as many of Crop A as they were making of Crop B themselves. This helps out the government as the workers won’t overwork themselves and can remain on task for longer periods of time in the short run and makes them feel better about working and more determined. Comparative Advantage Oxford Dictionary defines comparative advantage as:

Comparative Advantage is the ability of an individual or group to carry out a particular economic activity (such as making a specific product) more efficiently than another activity. Ricardo's theory of comparative advantage is typically used as the backbone of arguments in favour of free trade – in other words abolishing tariffs and quotas on goods imported from foreign countries. It is claimed that, by trading freely with other countries – even those that, on paper, are more efficient at producing goods and services – one can become more prosperous than by closing one's borders. Edmund Conway, Daily Telegraph 1

To show comparative advantage I will use an example below.

Here we see two countries that are particularly good at producing one good but not so much for the other good. France has the option of 10 million tons of pork or 20 1

The cost of France to produce an extra ton of pork is 2 tons of wine compared with Germany’s cost of an extra ton of pork is 0.5 tons of wine. We can say that Germany has comparative advantage in the terms of pork production however, the cost is inverted in the terms of wine as and extra ton of wine will cost France 0.5 tons of pork but it will cost Germany 2 tons of pork and so France will have comparative advantage in the production of wine.

Absolute Advantage

Absolute Advantage is the ability of an individual or group to carry out a particular economic activity more efficiently than another individual or group. Oxford Dictionary

Example:

Wales New Zealand

Lamb (Million Tons) 20 20

Beef (Million Tons) 10 20

What we can see in the above table is that per day Wales and New Zealand can produce 20 millions tons of lamb each or 10 million and 20 million tons of beef respectively per day. If the two countries were self-sufficient and had no need to trade then Wales could either make 20 million tons of lamb or they could make 10 million tons of beef. New Zealand on the other hand could make 20 million tons of lamb or 20 million tons of beef or anywhere along the production possibility curve, (It would be unreasonable to produce the two in the PPF rather than along it as it would lead to a misallocation of resources.)

Below we see a graph of the two product possibility frontiers

When self sufficient we can say that in Wales, The cost of one million tons of

ECON10120 – Economic Principles and Skills Student ID: 093238351 beef is two million tons of lamb and so the exchange ratio in Wales is 1:1. In New Zealand the cost of one million tons of beef is one million tons of lamb so the exchange rate in New Zealand is 1:1. If both countries were to produce at half of each so that the country has a smaller amount but obtaining both at the same time. (Wales producing 10 million tons of lamb and 5 million tons of beef and New Zealand producing 10 million tons of lamb and 10 million tons of beef) then we can see that New Zealand can produce 5 more tons of beef than Wales whilst maintaining the same amount of lamb. This is called Absolute Advantage as they can produce the same or more at both products than another country. Here we see that New Zealand has comparative advantage as it can produce the same amount or more than Wales when specializing in that particular good. Even though this may be the case, there will still be beneficial for Wales and New Zealand even though New Zealand will have this advantage over Wales. If Wales was to specialize in the production of lamb and New Zealand were to specialize in beef then the production would change to along the Y axis for Wales and X axis for New Zealand on the graphs, Wales would have 20 million tons of lamb and 0 tons of beef and New Zealand will have 0 tons of lamb and 20 million tons of beef. The countries will then bargain on what amounts by negotiation and until they reach an agreement. In this example we’ll say that Wales trade 7.5 million tons of lamb to 5 million tons of Beef from New Zealand. This will result in 12.5 million tons of lamb for Wales and 5 million tons of beef and 15 million tons of beef and 7.5 million tons of lamb for New Zealand. This means that after trade Wales has gained 2.5 million tons of lamb from the original equilibrium of 10 and has not lost any beef from the original equilibrium point of 5. New Zealand has gained 5 million tons of lamb from the original equilibrium point of 10 and lost 2.5 million tons of beef from the original point of 10. This will look like this to simplify:

Wales New Zealand

Original Amount Produced 10 Lamb 5 Beef

Amount Produced 20 Lamb 0 Beef

10 Beef 10 Lamb

20 Beef 0 Lamb

Amount Traded OUT: 7.5 Lamb IN: 5 Beef OUT: 5 Beef IN: 7.5 Lamb

Amount Consumed 12.5 Lamb 5 Beef

Amount Gained 2.5 Lamb

15 Beef 7.5 Lamb

5 Beef

So as we can see mathematically Wales have gone from being able to consume 15 million tons per day (Lamb + Beef) to 20 Million tons of one good only to 17.5 million tons. They have reached a new equilibrium that is not possible on their old PPF, which will look like this.

New Zealand have gone from being able to consume 20 millions tons that have been produced of both goods lamb and beef, than it remained the same amount and specialized in beef before trade which then it increased to 22.5 million tons consumed which is an increase of 2.5 million tons and a new place of their PPF shown below:

Conclusion Richard’s Theory of comparative and Absolute advantage means that trade will benefit countries by increasing production and efficiency beyond what it would be able to do self-sufficiently, however such examples only work in free markets and the inclusion of tariffs, quotas restrict trade and make it less favorable to trade then first seems.
