In the model of two countries (1, 2) and two products (X, Y): Country 1 has a productivity of 6X and 4Y (hours/person); Country 2 has 1X and 2Y productivity (hours/person); The exchange rate is 6X = 6Y. a. Compare the complementary benefits of two countries when dealing with each other. (1 dong)
b. Determine the framework of trade exchange between the two countries. (1 dong)

Exercise 2
The data is given in the following table:
Labor productivity
Country 1 Country 2
Product A (sp/hour): (4) l (2)
Product B (sp/hour): (1) l (3)

Let's define:
a. Basis and model of international trade between the two countries. (0,5d)
b. At what exchange rate will there be no trade between the two countries? (1.5 VND)
c. If two countries exchange the ratio 4A = 5B, how much time will be saved? (1 day)

Exercise 3
There are documents given in the following table:

Product Country 1 Country 2
X (hour/hour): (4) l (2)
Y (hour/hour): (1) l (3)
Each country has a total resource of 1200 hours of labor and spends 50% on each product when closed.
Determine the scale of production and consumption when the two countries closed their economies. (0,5d)
Let's determine the commercial basis, trade model and trading conditions of the two countries. (1.5 VND)
Under what terms of trade, country 1 is more profitable than country 2? (0,5d)
Determine the production and consumption benefits of the two countries when they specialize and do business completely with quantities of 200X, 200Y. (1.5 VND)
In QG1, 1 hour of labor is paid £8, country 2 pays $10. Determine the prices of X and Y in the two countries and the exchange rate band of the two currencies so that trade between the two countries takes place according to the above model. (1 dong)
