Multiple Choice Test

All 20 multiple choice questions will be graded (4 raw points for the correct answer, -1 raw point for the incorrect answer, 0 points for no answer). Choose one answer in each question.

1. For any given X < 100 same for both countries, country A can produce less of good Y than country B.

2. If the countries want to produce 60 units of X together, the maximum possible amount of Y that they can produce together equals approximately 54.

3. The opportunity cost of producing an additional unit of X is equal between the countries at all points of their PPFs.

4. If the countries join their production possibilities, their PPF will be given by X2 + X + Y2 + Y = 300.

2. Choose the correct statement about monopoly.

2. For a non-discriminating monopoly, price equals marginal revenue.
