		1/20A; 1/15A
		10A; 15A
		1/2A; 1A
		2A; 1/2A

Expert Solution

Answer 53

The correct answer is (e) 2A; 1/2 A

COUNTRY 1

We can see from above table that Country A can produce either 100 units of A and 0 units of B or 80 units of A and 10 units of B. This means that in order to increase production of B from 0 to 10 units he has to decrease its production of A from 100 to 80 units i.e. in order to produce 10 units of B he has to sacrifice 100 - 80 = 20 units of A. Thus in order to produce 1 unit of B he has to sacrifice 20/10 = 2 units of A. Hence opportunity cost of producing 1 unit of B for country 1 is 2 units of A i.e. 2A (NOTE : According to above table Opportunity cost of producing B is constant)

COUNTRY 2

We can see from above table that Country A can produce either 75 units of A and 0 units of B or 60 units of A and 30 units of B. This means that in order to increase production of B from 0 to 30 units he has to decrease its production of A from 75 to 60 units i.e. in order to produce 30 units of B he has to sacrifice 75 - 60 = 15 units of A. Thus in order to produce 1 unit of B he has to sacrifice 15/30 = 1/2 units of A. Hence opportunity cost of producing 1 unit of B for country 2 is 1/2 units of A i.e. (1/2)A (NOTE : According to above table Opportunity cost of producing B is constant)

Hence, the correct answer is (e) 2A; 1/2 A

question 5 and 6 Data on county A and Country B are as follows: Country A: Exports (600), Imports (700), GDP (1500). Country B: Exports (900), Imports (1200), GDP (3000). Based on the data above, we can conclude that: Country A is more open than Country B. Country B is more open than Country A. None of the two countries can benefit from international trade since the sum of their exports and imports is less than the value of their...

Question) It is known that, on average, 2 people in 5 in a certain country are overweight. A random sample of 400 people is chosen. Using a suitable approximation, find the probability that fewer than 165 people in the sample are overweight. It is based on using normal distribution as an approximation for the binomial distribution. Please explain in detail with all logical steps for better understanding so as to how to solve these types of questions.

Question 1 : Suppose country A and country B are deciding whether to install new incinerator to reduce regional air pollution or not. The new incinerators can reduce the domestic pollution and the cross-border pollution that affects both countries. To quantify the analysis, suppose that if country A installs the new incinerator, it generates benefit of $1 million from reducing domestic pollution and of $1 million from reducing cross-border pollution. But, the benefit from reducing cross-border pollution will be equally...
