International Economics Graduate Comp Study Guide

Explain the effects of a tariff on the welfare of a country imposing the tariff, under each of the following assumptions:

The country is a small country
The country is a large country

Suppose an industry is characterized by perfectly competitive firms and these firms exhibit external economies of scale. How do the implications of trade compared to autarky differ in such a model compared to the Standard Model?

Suppose an industry is characterized by monopolistically competitive firms and these firms exhibit internal economies of scale. How do the implications of trade compared to autarky differ in such a model compared to the Standard Model?

Assume that an industry is characterized by monopolistically competitive firms and these firms exhibit internal economies of scale. Suppose that the firms are heterogeneous in that they have different marginal costs. What will happen when there is industry integration due to international trade?

What factors account for or contribute to external economies of scale? Show how equilibrium is determined in an industry characterized by monopolistically competitive firms subject to external economies of scale. If an industry characterized by monopolistically competitive firms subject to external economies of scale, what happens when the industry moves from autarky to international trade?

What is intra-industry trade?  How is it measured?



I will also upload the sample work(urban econ).

Need to answer these questions one by one.The length is one paragraph(not too short) for one question. If the question needs us to provide diagrams, just provide. After you give the work to me, I will ask my classmate to check for me! The study guide is very important to me. I met couple tutors before, they rejected to fix the work for me after I asked them to fix. I rarely ask them to fix stuff but if it is necessary. If you are the tutor who does not want to do the service after you turn in the work. Please do not click it.  Thank you very much.
