Suggested background knowledge

To follow the course well, you should have some basic knowledge about solving constrained and unconstrained optimization problems, integral calculus and probability theory (especially continuous random variables). Furthermore, you should be familiar with basic microeconomic concepts such as General Equilibrium, and basic econometric concepts such as regression analysis and instrumental variables.


Mission & Content Summary
MISSION

Globalization is a fascinating phenomenon – complex and constantly evolving - with important implications for economic policy and people's livelihoods. Brexit, the "trade war" between the United States and China, and the disruptions created by the Covid-19 pandemic are just the most recent examples of how international economic integration affects everyday life. This course examines the causes and consequences of international trade and investment building on workhorse models and recent empirical evidence. It investigates why nations trade, what they trade, and how trade affects aggregate welfare and inequality. One of the great features of research in international trade is the interplay between theoretical models, rigorous empirical analysis and the use of quantitative methods. Theoretical models discipline our thinking and guide our empirical analysis. Empirical evidence guides the development of models and helps us distinguish between different economic mechanisms. Throughout the course we will put particular emphasis on this interplay between theoretical and empirical work. This course aims to familiarize students with the newest methodologies and findings in the field of international trade. Because of its methodological aspects, it may be particularly interesting for students thinking about a research career.

CONTENT SUMMARY

The main topics covered are:

  • The History of International Trade since the Industrial Revolution.
  • Ricardian Trade Theory, from Ricardo to Eaton-Kortum.
  • Heckscher-Ohlin Trade Theory.
  • Increasing Returns and the New Trade Theory.
  • Firm Heterogeneity: the Melitz model and its applications.
  • New empirical insights on trade, development and inequality.
  • Selected topics from current research in international trade and economic geography

Intended Learning Outcomes (ILO)
KNOWLEDGE AND UNDERSTANDING
At the end of the course student will be able to...
  • Define the concept of comparative advantage and understand how it shapes trade patterns.
  • Describe the main reasons for international trade and their relative importance in reality.
  • Explain the methodology used by modern economic models to quantify the gains from trade and the effects of changes in trade costs.
  • Summarize the main insights obtained by models which introduce firm heterogeneity in international trade.
  • Discuss the empirical strategies used to isolate a causal effect of international trade on national income and inequality.
APPLYING KNOWLEDGE AND UNDERSTANDING
At the end of the course student will be able to...
  • Solve the workhouse models of international trade.
  • Analyze their main properties and comparative statics, both analytically and using specialized software (e.g. MATLAB).
  • Evaluate and argument using a rigourous economic model and mathematical proofs.
  • Develop an empirical strategy to assess the impact of international trade on economic outcomes.
  • Read and critically discuss frontier research in international trade.

Teaching methods
  • Face-to-face lectures
  • Exercises (exercises, database, software etc.)
  • Group assignments
DETAILS

Regular problem sets allow students to apply the knowledge acquired during the lectures. These problem sets consist in theoretical and empirical exercises, which are to be solved either analytically or using a computer. They can be done in groups, and are discussed during dedicated sessions with the Teaching Assistant of the course. They also are graded.


Assessment methods
  Continuous assessment Partial exams General exam
  • Written individual exam (traditional/online)
  •     x
  • Group assignment (report, exercise, presentation, project work etc.)

    ATTENDING AND NOT ATTENDING STUDENTS

    Regular problem sets allow students to apply the knowledge acquired during the lectures. To deepen their understanding of the models discussed in class, students analytically and computationally solve such models in the problem sets. Students also apply the empirical methodologies such as estimating the gains from trade, e.g. from current policies such as Brexit. The final exam tests the students understanding of the models, empirical methodologies and empirical findings introduced in the lectures and discussed in the sessions with the teaching assistant. The exam features short questions to test the basic knowledge and key concepts from the empirical and theoretical literature on international trade. The exam also features a longer question which tests students ability to make formal arguments using rigorous economic models and empirical methodologies and relates those to real-world economic questions.
