International Macroeconomics (ECO-AD-INTMACECO)

ECO-AD-INTMACECO

Purpose

Professor: Giancarlo Corsetti (email: [email protected]) 

Course Description
The primary goal of this course is to provide the foundations of the core general equilibrium models of the international business cycles and the international financial system. Building on this core model, the lectures will introduce students to frontier theoretical and empirical work on trade, market structure, macroeconomics of capital market integration, sovereign risk and macroeconomic and monetary stability. Students will be assessed on an assignment requiring some analytical and/or quantitative work; and
a referee report on a paper requiring them to map the contribution in the literature, discuss methodology and identify open issues. The website includes math-lab code for some of the models. Course readings will be provided during lectures. Standard reference books are Open Economy Macroeconomics (henceforth, OEM) by Martin Uribe and Stephanie Schmitt-Grohe and Foundations of International Macroeconomics by Kenneth Rogoff and Maurice Obstfeld.
