International Trade

Course Description

An intensive examination of modern theories of international commercial policy and the international trade system. Developments in trade theory, and restrictions of international trade are discussed.

Course Objectives

The course will enable students to gain an understanding of how the international economy works and how economic theory can be used to understand issues of public policy, the impact of trade on economic development, and the impact of trade restrictions.

Course Materials


The course will mainly follow the textbook “International Economics: A Heterodox Approach” by Hendrik Van den Berg (3rd edition), 2017, Routledge. The required readings from this textbook are listed below.

The textbook is available from amazon and bookdepository.

You will find a study guide for the textbook here.

Sometimes it is helpful to have access to an alternative textbook that explains the material in a different way. For this purpose I recommend: Robert J. Carbaugh, International Economics (15th edition), 2014, Cengage.

An additional study guide for (only) the orthodox models that includes solved problems is:
Salvatore, Schaum’s Outline of International Economics, 4th Edition, 1995, McGrawHill.
Available from amazon and bookdepository

Course Requirements:

Students must read the corresponding chapters of the textbook before each session. Reading the economic and political press will also be helpful.

Class meets Mondays at 15:05 till 17:30.

Electronic devices, i.e. laptops, are discouraged from use during class sessions. See for the reasons.

Course Prerequisites:

Students need to have passed principles of microeconomics and principles of macroeconomics before enrolling in this course.

Grading Guidelines:

Grading ComponentWeight
Class Participation and Quizzes20%
Midterm Examination20%
Final Examination40%

(Class) participation (at the level of an “A”) requires that you attend class regularly and always contribute to the discussion by raising thoughtful questions, analyzing relevant issues, building on other’s ideas, synthesizing across readings and discussions, expanding the class perspective, and appropriately challenging assumptions and perspectives. You help your fellow students. Contributing in the aforementioned ways only (“B”) sometimes, (“C”) rarely, or (“D”) never diminishes not only your own but your fellow students learning opportunities.

In case you were excused from the midterm exam, the make-up exam for the missed midterm will be administered with the final exam.

You are allowed to bring a dictionary and pocket calculator to all exams. For the final exam only, you are allowed to bring a single-sided page DIN A4 with hand-written notes.


A typical 3 credit course requires 150 hours of your time. The table below identifies how I expect those 150 hours will be allocated. While you do not receive direct marks for reading, reading will affect your class participation mark (your ability to participate in class discussions and activities) and your final exam mark. While some weeks have more readings than others, you should be able to read the required reading in an average of 2 hours per week.

Review and Homework (4 hours / week)60 hours
