Question:
a. Compared with the no-trade equilibrium, how much does industry demand D increase? How much does the number of firms (or product varieties) increase? Does the demand curve D/NA still apply after the opening of trade? Explain why or why not.
b. Does the d1 curve shift or pivot due to the opening of trade? Explain why or why not.
c. Compare your answer to (b) with the case in which Home trades with only one other identical country. Specifically, compare the elasticity of the demand curve d1 in the two cases.
