Course overview and learning objectives

Macroeconomic events are a fundamental source of changes in the business environment, markets, and society. The purpose of this course is to give you a better understanding of the macro-economy, to familiarise you with the workings of the global economy and the main factors that determine the incomes of nations and their fluctuations. We will consider a range of questions such as: why are some countries growing faster than others; how does technology and institutions affect the economy; why do business cycles occur; what are the determinants of exchange rates and inflation; what is driving unemployment; what are the principles and motivation underlying monetary and fiscal policy.

After this course, you should be able to recognise and construct logical economic arguments, understand when, why and how the government makes important policy decisions, read policy reports and non-technical academic papers that can be used for the writing of policy notes. The aim is to provide a set of general skills portable across a range of industries, professions, and countries, which will make it possible to understand the forces that will dominate the domestic and global business environment in the immediate future as well as over the coming years.

The course consists of twelve lectures. Sessions 1 to 5 cover the long-run while 6 to 12 covers the short/medium-run. Classroom participation is essential. You are encouraged to contribute with insights from your own experiences. Classroom participation will enhance your ability to think critically and to organize your thoughts in a clear and insightful manner. Throughout, theoretical concepts are backed and illustrated by real-world examples from a macroeconomic perspective and from a corporate perspective. The focus of the course will be on policy oriented questions and not as theoretical and model oriented as a standard macroeconomics course in a research oriented master. However, students are expected to handle basic algebra.

Reading material

Possible textbooks: Macroeconomics, S. Williamson, 4th edition.
Macroeconomics, Charles. I. Jones, 3rd edition.

In addition, the course contains additional readings available on the course website.


Homework: by groups of 4 or 5max. Due for April 30 (midnight); choose a policy YES/NO question which deals with a current issue in macroeconomics (some suggestions will be provided in class but students can come up with their own question).  Using policy and academic articles (see among others IMF, World Bank, ECB, Federal Reserve, Economic Policy, NBER, CEPR discussion papers, see also in VOX the columns that refer to research articles) or press articles (FT, The Economist...), provide a critical answer to the question. You are expected to define precisely the question and provide an answer weighting the pros and cons in a 6 pages document (max. 4000 words). Providing data to justify your conclusions is strongly encouraged.

Final exam: Multiple choice questions, exercises and short essays

The files below contain sample questions to practise for the exam. On the quantitative side, students are expected to handle basic calculus. The sample quantitative exercise is for those interested in technical exercises and beyond what can be expected for the final exam.

Sample multiple choice  - Grading policy for multiple choice

Sample short exercises and essays

NEW! Due to the special circumstances, the final exam will be limited to a one hour exam with multiple choice questions (20 questions). Grades will be based on the group homework (60%) and the final MCQ exam (40%)
