Answer to Question 1

In the case of a private good, the individual enjoys all of the benefits and pays all of the costs so it is important to gather product information. In the case of a public good, the individual receives only a fraction of the benefits and pays only a fraction of the costs. Moreover, it is uncertain whether one individual's gathering information will have any impact on the public goods provided anyway.

Answer to Question 2

In China, to produce 8 cloths has an opportunity cost of 16 cheeses, so the opportunity cost of 1 cloth is (16 cheese)/(8 cloths) = 2 cheeses per cloth. In Pakistan, to produce 4 cloths has an opportunity cost of 12 cheeses. Hence the opportunity cost of 1 cloth is (12 cheeses)/(4 cloths) or 3 cheeses per cloth. Because China's opportunity cost of a cloth is lower, China has the comparative advantage in producing cloth.
In China, to produce 16 cheeses has an opportunity cost of 8 cloths, so the opportunity cost of 1 cheese is (8 cloths)/(16 cheeses) = 1/2 cloth per cheese. In Pakistan, to produce 12 cheeses has an opportunity cost of 4 cloths. Hence the opportunity cost of 1 cheese is (4 cloths)/(12 cheeses) or 1/3 cloth per cheese. Because Pakistan's opportunity cost of a cheese is lower, Pakistan has the comparative advantage in producing cheese.
