Lecture: Makroökonomik offener Volkswirtschaften / Open Economy Macroeconomics
(winter semester, in German)
Wie wirkt sich eine Zinswende in den USA auf Schwellenländer oder den Euro-Raum aus? Warum haben fixe Wechselkurssysteme in der Vergangenheit Währungen und Volkswirtschaften stabilisiert aber zugleich immer wieder zu massiven – durch Währungsspekulationen ausgelösten – Krisen geführt? Wieso konnte die Aufhebung der Bindung des Schweizer Franken an den Euro polnische Häuslebauer in den Ruin treiben (und was sollten zukünftige Bauherren und Staaten daraus lernen)? Ist der Verfall des Britischen Pfunds (im Vergleich zum Euro) in Reaktion auf das Brexit-Votum „good news or bad news“ für das Vereinigte Königreich?
Ziel der Veranstaltung „Makroökonomik offener Volkswirtschaften“ ist nicht, einfach Antworten auf diese Fragen zu geben, sondern die Studierenden in die Lage zu versetzen, Antworten auf diese und ähnliche Fragen selbst zu finden.
Wichtige Themenbereiche sind die Zahlungsbilanz, die Zusammenhänge zwischen Geldmarkt, Zinssätzen und Wechselkursen sowie die Beziehung zwischen Produktion, Exporten und dem Wechselkurs in der kurzen und der langen Frist.
Im Zentrum des Moduls steht ein graphisches Tool, das erlaubt, die Effekte von Geld- und Fiskalpolitik (und anderen makroökonomischen Schocks) durch den Geld-, Devisen- und Gütermarkt zu verfolgen. Dies gilt sowohl für flexible wie auch für fixe Wechselkurse. Im ersten Teil des Moduls wird dieses Modell schrittweise entwickelt, indem zunächst einzelne Modelle des Geld-, Devisen- und Gütermarktes in einer offenen Volkswirtschaft entwickelt und analysiert werden. Im zweiten Teil werden die einzelnen Modelle kombiniert und ein graphisches Tool entwickelt, das es ermöglicht, den Einfluss verschiedener Schocks auf die verschiedenen Märkte simultan zu analysieren. Im dritten Teil wird das graphische Tool eingesetzt, um den Einfluss von Geld- und Fiskalpolitik auf Produktion, Beschäftigung, Preisniveau und Wechselkurs bei flexiblen Wechselkursen zu analysieren. Im vierten Teil werden die Möglichkeiten der Geld- und Fiskalpolitik bei fixen Wechselkursen, sowie die Möglichkeit einer politisch administrierten Abwertung analysiert. Anhand verschiedener Fallbeispiele werden verschiedene der o. g. Aspekte exemplarisch vertieft.

Lecture: International Economics (summer semester, in English)
This module provides an introduction to the economic analysis of international trade. First, students receive an overview of the current and historical developments of international trade. Based on this, different basic theoretical models regarding international trade are presented and critically evaluated.
The focus of this module is on the main fundamental theories of international trade like, for example, the Ricardo model, the specific-factors model and the Heckscher-Ohlin model.
“Everyone profits from free trade” is the central implication of the Ricardo model. This statement is the starting point to critically analyze the model (exemplary for other basic economic models). In this context, the focus will be on the utilization of theoretical models by economists, the qualitative features of a model, if a realistic model is always better, and how its implications are interpreted correctly.

Lecture: Fundamentals of International Trade (winter semester)
Both theoretical and empirical research on international trade has surged in the last two decades. All these recent developments are deeply rooted in two fundamental and analytically very tractable models of international trade like, for example, the basic two-country-two-goods Ricardian model and the model by Krugman (1980). One of the main objectives of this module will be to put students in a position to solve such models analytically and to deepen their understanding of economic modeling in general. More recent state of the art models are covered on an intuitive basis. Standard empirical tools like, for example, gravity estimation are introduced in this module. Moreover, criteria for a critical evaluation of models in economics are developed.
Lecture: Advanced International Trade (summer semester)
Over the last two decades, academic research on international trade, foreign direct investment (FDI), outsourcing and trade policy has been booming. This literature is at the core of this module. Possible topics may include among others:
- International trade and firm heterogeneity (Melitz 2003, Chaney 2008)
- The international organization of production (Antràs 2003)
- International Trade, Global Sourcing and International NGO activity
- Foundations for quantitative trade analysis: Eaton and Kortum (2002)
- Into the machine room of our models – the CES price index
- Trade Policy and Identity Politics: how to make sense of political support for Trump’s trade policy (Grossman and Helpman 2021)
Lecture: The Empirics of International Trade (irregular)
Trade in commodities or final goods is today only a minimal part of international trade. The bulk of international trade is actually made of intermediate parts, components, and services exchanged along international global value chains.
This module encompasses some of these aspects (trade in value added, outsourcing, GVCs, FDI, partnerships), which find little coverage in basic trade classes, but characterize a modern and globalized economy. The focus lies on issues that animate the public debate (mapping GVCs, the impact of outsourcing on jobs and wages, FDI motives …).
A second part of the module is dedicated to one of the most robust empirical finding in economics, the gravity equation, which, for this reason, has also become the workhorse tool to investigate the effects of trade policy and regional economic integration. Article headings like “Can Brexit defy gravity?” will suddenly make sense …
A detailed syllabus of the class containing the course structure and the readings for the course will be handed out to students at the beginning of the semester in the classroom (and Stud.IP).
Seminar: Recent Topics of International Trade (each semester)
This seminar covers different topics in the fields of international trade, international macroeconomics, international organization of production, trade policy, identity politics and globalization backlash.
Seminar: Advanced International Economics (irregular)
This seminar covers different topics in the fields of international trade, international macroeconomics, international organization of production, trade policy, identity politics and globalization backlash. It has a clear research orientation and enables students to subsequently engage in their own independent research at the frontier.
