MACROECONOMICS

MACROECONOMICS

Giovanna Vallanti

Instructional goals

This course aims at providing the methodological and theoretical tools to understand how the economies work and to explain the past and current economic developments. We will focus on the stylized facts of business cycle fluctuations and economic growth, the determinants of unemployment and inflation. We also discuss whether and to what extent economic policy may improve macroeconomic performance.

Intended learning outcomes

Knowledge and understanding: Students can understand the causal links among the main macroeconomic variables, know why the business cycle occurs and know the determinants of the long run economic growth. Moreover, they understand the macroeconomic effects of both countercyclical and structural economic policy interventions. Applying knowledge and understanding: Students are able to: (1) apply macro models to formulate rigorous reasoning on different macro issues, (2) understand the content of articles and documents related to macroeconomic issues. Making judgments: Students are able to critically analyze the effect of different shocks on both the domestic economy and the global economy. They are also able to evaluate the role of the key economic actors and the effects of policy actions in different economic scenarios. Communication Skills: Students are able to (1) process data, documents and opinions on the most important macroeconomic issues (2) clearly present to an audience of peers their reasoning on a given macroeconomic issue as well as state the theoretical motivations underlying their conclusions. Learning skills: Classes, lecture notes, and articles allow students to undertake with autonomy more advanced courses of economics and to plan and conduct independently a small research project (e.g. an undergraduate dissertation) on macroeconomics topics. Personal development skills: - Self-management - Problem solving - Application of numeracy skills

Reference Books

All course materials are made available via Moodle, including notes to accompany the lectures, but this can be supplemented with additional background reading. The recommended supplementary text is: Blanchard, O. Giavazzi F & Ameghini A., Macroeconomics: A European Perspective 4/E, Pearson, 2021 (alternatively the 3/E, 2017) Findlay, D. Study Guide for Macroeconomics Fifth (5th) Edition (optional) If you would like to gain further insight into what macroeconomics studies, we suggest looking at the following popular book: D Coyle GDP: A Brief but Affectionate History (Princeton University Press, 2014)

Teaching Methods

Teaching is based on lectures and practice session in which written exercises will be solved and discussed with the students. Problem sets are made available few days before the practice session with the TA. The solutions of the problem set will be discussed in class. Students should attempt the assigned problems before attending classes, as they will have to hand them in every week. Students are expected to make positive contributions to class discussions and during the lectures. Valuable contributions students will be positively assessed in the final evaluation.

Assessment Method

Written final exam and problem sets handed in during the course. The final exam is based on the topics covered during the lectures and classes, the chapters of the textbook and the supplementary readings assigned during the course The student will be evaluated as follows: 1. Delivery and upload of 8 Problem Sets (plus an intermediate mock exam) into the course’s dedicated platform. Each problem set and the mock exam will be graded out of 2 points. The average score obtained in the problem sets will be added to the grade obtained in the final exam taken in the summer exam session. This activity is meant to assess knowledge and comprehension skills and competencies during the semester. (Only for students attending the classes and taking the exam in the December -January session) 2. Final exam:100% on the final grade. Through this activity, knowledge and comprehension skills and competencies will be assessed The final exam will be composed of a mix of open questions, multiple choice questions and exercises, through which the student will demonstrate to know theoretical concepts and how to apply them to real world cases, thus proving that he/she has acquired a good study method, critical skills and the ability to learn, requested to continue autonomously the study of the subject matter. The number of questions within each typology will be decided by the instructor during the course and it will be communicated to students before the exam. In order to pass the exam, it is necessary that the student gets at least 18/30 in each of the aforementioned activity. The correct answer to all multiple-choice questions, the demonstration of an excellent knowledge in open questions and the correct resolution of exercises leads to getting 30/30 with the possible awarding of cum laude.
