شرح مبسط لموضوع المزايا المطلقة والمزايا النسبية حاول تفهمه قبل الدخول في هذا الموضوع ( القسم الثاني من بارت وان ) international trade
The principle of comparative advantage states that if nations (or individuals) specialize in the production of goods and services that they can produce at lower opportunity cost relative to other nations, then there can be mutual gains from trade. As a result, there will be more efficient production and consumption. Applying the efficiency principle, this means that mutually beneficial trade allows each nation to consume a mix of goods that is beyond what they could produce alone – the whole pie is bigger, so everyone can have a larger slice.
Example to see gains from trade:
Assume that Jay and Leah can spend the day either washing cars or mowing lawns. The table below shows how much of each task they could accomplish in one day if they spent the whole day doing just that task. For example, Jay could wash 20 cars or mow 5 lawns in one day.
______________________________________________

Jay Leah
______________________________________________

Cars washed 20 15
Lawns mowed 5 3
______________________________________________

Note: Jay has the absolute advantage in both goods. This does not mean that he has comparative advantage. Even though he is “better” at producing both goods than Leah, he can still benefit from trading with her.
Question: Use the principle of comparative advantage to illustrate how specialization can make them more productive than they can be alone.
Steps:
1. Calculate the opportunity cost of each activity for each person.
Jay

The opportunity cost of mowing 5 lawns is washing 20 cars.
Þ the opportunity cost of mowing 1 lawn is washing 4 cars.
Þ the opportunity cost of washing 1 car is mowing ¼ of a lawn.
Leah

The opportunity cost of mowing 3 lawns is washing 15 cars.
Þ the opportunity cost of mowing 1 lawn is washing 5 cars.
Þ the opportunity cost of washing 1 car is mowing 1/5 of a lawn.
2. Use the opportunity costs to see who has comparative advantage (lower opportunity cost) in each good, and therefore who should specialize in each good.
Jay has a lower opportunity cost for mowing lawns so he has the comparative advantage in lawns (he gives up only 4 cars per lawn while Leah gives up 5 cars).
Leah has a lower opportunity cost for washing cars so she has the comparative advantage in cars (she gives up only 1/5 of a lawn per car while Jay gives up ¼ of a lawn).
Þ Jay should specialize in mowing lawns and Leah should specialize in washing cars.

3. Use the opportunity costs of each good to figure out how much they would be willing to pay or accept in a trade.
Since Jay is doing all the lawn mowing and Leah is doing all the car washing, we can see that Jay will trade some lawns for Leah’s car washing.
Questions: a) how many lawns would Jay be willing to mow for Leah if Leah washes one car for Jay?
b) how many lawns would Leah accept as a trade for each car she washes for Jay?
Answers: a) Jay would mow up to ¼ of a lawn, but not more, for each car that Leah washes for him (because this is his opportunity cost or what he would have to give up if he washed a car himself).
b) Leah would accept anything above 1/5 of a lawn, but not less, for each car that she washes for Jay.
Notice that there is a “window” of opportunity for trade. Any amount of lawns between ¼ and 1/5 will be acceptable to both Jay and Leah and make them both better off.
Example of a mutually beneficial trade:
Suppose Jay mows 6 lawns for Leah.
What is the most that Leah would pay Jay (in car washes) for these 6 lawns?
® Leah will pay up to 30 cars for this because for her the opportunity cost of 1 lawn is 5 cars, so the opportunity cost of 6 lawns is 30 cars.
What is the least that Jay will accept for these 6 lawns?
® Jay will accept anything greater than 24 cars for this because for her the opportunity cost of 1 lawn is 4 cars, so the opportunity cost of 6 lawns is 24 cars.
If Leah gives Jay 27 cars for the 6 lawns (or any other number between 24 and 30) then they will both be better off.
Jay gets 27 cars washed at a “price” of only 6 lawns – if he were to wash 27 cars himself he would have to give up 6.75 lawns (27 x 0.25) – he is therefore better off by ¾ of a Lawn.

Leah gets 6 lawns mowed at a “price” of only 27 cars – if she were to mow 6 lawns herself she would have to give up 30 cars (6 x 5) – she is therefore better off by 3 cars

What is a real life example of comparative versus absolute advantage

An example would be...

The cost of producing a barrel of oil in the US is 10 labor hours and 12 labor hours in Mexico. The cost of producing a yard of cloth in the US is 12 labor hours and 13 labor hours in Mexico.

The United States has ABSOLUTE advantage in both markets, meaning it is cheaper for us to produce both of these items in terms of labor hours.

If the US and Mexico opened trade in the oil and cloth market, the US's relative price for oil would be

10 / 12 = 1 / x
x = 1.2 yards of cloth per barrel of oil

and the US price for cloth would be:

12 / 10 = 1/x
x = .83 barrels of oil per yard of cloth

Meanwhile, Mexico's relative prices would be:

Oil: 12 / 13 = 1/x
x = 1.083 yards of cloth per barrel of oil

Cloth: 13 / 12 = 1/x
x = .923 barrels of oil per yard of cloth

Mexico has comparative advantage in oil because its relative cost per barrel of oil is cheaper than in the United States (US: 1.2 vs. Mexico: 1.083). The US, however, has comparative advantage in cloth (US: .83 vs. Mexico: .923)

This means that the United States could trade cloth with Mexico at a profit

قبل ما تبدء تذاكر موضوع ميزان المدفوعات balance of payment دا تلخيص بسيط حاول تفهمه
خد بالك ان كل اللي فات عبارة عن تحضير هيسهل عليك كتير المذاكرة

THE BALANCE OF PAYMENTS (BP)


The balance of payments is the summary statement of the flow of economic transactions between the residents of one country and the rest of the world over a given period of time.

This summary statement comprises of such items as the export and import of all goods and services; all capital loans abroad and all borrowing from foreign countries; all gifts to and from foreign countries, including foreign aid; and all movements of gold and international reserves into and out of the country.

In this country, the Department of Commerce is responsible for calculating the balance of payments.

How are debits and credits defined in international transactions?

A debit represents the importing of an item such as a good, a service, a stock or a bond, a bank deposit, or gold. A debit adds to a nation’s demand for foreign currency. It receives a negative sign (-) in the balance of payments table.

A credit represents the exporting of an item such as a good, a service, a stock or a bond, a bank deposit, or gold. A credit item adds to a nation’s supply of foreign money. It receives a positive (+) in the balance of payments table.

Consider a few examples to aid in your understanding of the balance of payments:

Suppose a U.S. household purchases a car from Japan. The import of the car into the U.S. is recorded on the debit side (-) and creates a demand for Japanese currency (Yen). It adds to the supply of dollars.

Suppose a U.S. business sells a bond to a British household. The U.S. business, then, exports a bond. This would appear on the credit side (+) of the BP. It would increase the supply of British pounds. It adds to the demand for dollars.

Suppose the US gives wheat to Egypt. The exporting of the good, even as a gift, is recorded as a credit (+) and is called a unilateral transfer.

Assume a US citizen travels as a tourist to Germany. His expenditures in that country are classified as a debit (-) because he purchases (imports) a service (tourism) from that country. It also creates a demand for German marks.


The BP is often divided into three sections: current account, capital account, and financing method (deficit or surplus). A simplified table is as follows:

I. Current account

A. Merchandise
1. Exports (+)
2 Imports (-)

B. Services
1. Military (net)
2. Travel and transportation (net)
3. Investment income (net)

Balance of goods and services = A + B

C. Unilateral transfers
1. Government grants (excluding military)
2. Remittances and pensions

Balance on current account = A + B + C

II. Capital account

D. Long-term capital movements or flows
E. Short-term capital movements or flows

Official reserve transactions balance = A + B + C + D + E
“The line”______________________________________

(There is some debate about where to draw the line to determine the balance of payments surplus or deficit. Some economists draw the line after long-term capital movements but before short-term capital movements, since short-term assets are temporary and can be withdrawn at a moments notice.)

III. Financing (deficit or surplus) method
F. U.S. official reserve assets (net)
G. U.S. liabilities to foreign official agencies

(Official reserve assets of the U.S. include (1) gold, (2) convertible foreign currencies,
(3) reserve position at the International Monetary Fund (IMF), and Special Drawing Rights (SDRs). An SDR created by the IMF in 1968 because of a shortage of international liquidity is the official unit of account used between the IMF, central banks, and governments. Foreign official agencies are central banks of other countries that lend to the U.S. when they experience a deficit
