  • Be able to identify the assumptions, the logic and the economic policy suggestions of the different macroeconomic models;
  • Use macroeconomic theoretical frameworks as tools for the analysis of current events;
  • Analyze basic macroeconomic data referred to variables such as prices, money supply, government deficit and employment
  • Be able to assess the appropriateness of country specific fiscal and monetary policies relative to the main macroeconomic indicators and the declared objectives of the Government and of the Central Bank.

COURSE DESCRIPTION:

This course is structured in two modules that will be taught in parallel during the semester.

The first module deals with microeconomics, i.e. the set of tools economists use to study the choices made by individuals in their roles of consumers, employees, investors and business managers and the effects of individual choices on market outcomes.

In particular, this first module focuses on:

  • rational choice theory and its claim that changes in income and prices are the determinants of consumer’s consumption choices;
  • the expected utility theory approach, according to which choices under uncertainty can be modeled as lotteries;
  • the demand for insurance policies and the limitations of the rational choice theory;
  • the difference between short-run and long-run cost functions;
  • how firms choose inputs, output and prices according to the different market structures in which they operate;
  • the difference between partial and general equilibrium analysis and the two fundamental welfare theorems;
  • why public goods and externalities represent the two main reasons for market failures and government intervention.

The second module deals with the fundamental macroeconomics models, and their ability to interpret the real-world economic phenomena. The topics addressed by the instructor include the factors affecting changes in aggregate variables, such as GDP, unemployment rates, aggregate demand, aggregate supply, interest rates, price levels, and so on , in the context of contemporary monetary market economies.

In particular, this second module focuses on:

  • the fundamental building blocks of Keynes’s macroeconomic theory;
  • the structure and the logic of the IS-LM model as a tool to determine the general equilibrium and the impact of economic policies both in a closed and an open economy;
  • the determinants of aggregate variables and how both fiscal and monetary policies can be effective tools for dampening business cycle and counteracting the main pathologies affecting actual economic systems, such as recession, unemployment, and crisis;
  • the main causes of unemployment and how to promote employment according to the different theoretical approaches;
  • the main determinants of economic growth;
  • how financial markets affect the real economy;
  • the relation between short-term and long-term interest rates through the yield curve and how expectations of financial markets are influenced by the behavior of central bank and the level of economic activity.

With reference to all topics listed above, students will be asked to develop a critical attitude towards the realism and the soundness of the assumptions underlying the various models and the ability to use the relevant elements of the economists’ toolbox to specific case studies.

INSTRUCTIONAL FORMAT:

The class will meet for 2 hours (gross of interclass break), four times a week, for a total of 42 sessions. In every week, one of the sessions will be devoted to exercise and case studies. After an introduction aimed at providing the needed background, participants are required to read the materials related to the class and to be prepared prior to coming to class. Classes will consist of a lecture by the instructor, to be followed by a discussion of the main topics and, possibly, of the assignments.

 ASSESSMENT OVERVIEW:

Class Participation:  This grade will be calculated to reflect your participation in class discussions, your capacity to introduce ideas and thoughts dealing with the texts, your ability use language effectively, and to present your analysis in intellectual, constructive argumentation. If you cannot attend classes your participation can be shown by interacting with your instructor during office hours, i.e. by asking about specific subjects of the syllabus and discussing assignments.

Assignments: Students will be required to submit home assignments timely. These will be exercises on analytical and/or graphing tools, comments on suggested readings on examples of economic challenges, opportunities, problems or risks faced by households, firms or nations.

Mid Term Exams*: The midterms are designed to establish and communicate to you the progress you are making towards meeting the course learning objectives on both Part I and Part II. Your abilities will be tested in two important areas of competency: the amount of information you master and the accuracy of the information you present.
Structure: A combination of 6 to 10tests on each part, possibly including ‘true or false’, open questions, analytical exercises and graph comprehension. Prior to the examinations, a comprehensive review will be given during class.

 Final Exam: Your abilities will be tested in three important areas of competency: the amount of information you master; the accuracy of the information you present, your ability to apply your knowledge to discussing real-world cases.

Structure: A combination of 12 tests, 6 on part I and 6 on part II, possibly including ‘true or false’, open questions, analytical exercises and graph comprehension. Prior to the examinations, a comprehensive review will be given during class. The final exam will generally include an oral discussion through which the instructor will assess the significance you ascribe to the facts and ideas you have integrated across your study in this course.

*For students not attending classes, the mid-term exams will be waived and the grade will be calculated attributing a 70% percentage to the final exam.

 

CLASS/INSTRUCTOR POLICIES:

Professionalism and communications: As a student, you are expected to maintain a professional, respectful and conscientious manner in the classroom with your instructors and fellow peers.
You are expected to take your academic work seriously and engage actively in your classes. Advance preparation, completing your assignments, showing a focused and respectful attitude is expected of all students. Simply showing up for class or meeting minimum outlined criteria will not earn you a good grade in this course. Utilizing communications, properly addressing your faculty and staff, asking questions and expressing your views respectfully demonstrate your professionalism and cultural sensitivity.

Attendance and Classroom behavior: Although attendance is not compulsory, it is highly recommended. All students must have a respectful attitude towards the professor as well as the classmates.

Arriving late / departing early from Class: Once they have decided to attend, students must behave consistently. Arriving late or leaving class early is disruptive and shows a lack of respect for instructor and fellow students.

Make-up classes: The instructors reserve the right to schedule make-up classes in the event of an unforeseen or unavoidable schedule change. Make-up classes may be scheduled outside of typical class hours, as necessary. 

Missing Examinations: Examinations will not be rescheduled. Pre-arranged travel or anticipated absence does not constitute an emergency and requests for missing or rescheduling exams will not be granted.

Use of Cell Phones, Laptops and Other Electronic Devices: Always check with your instructors about acceptable usage of electronic devices in class. Inappropriate usage of your electronic devices will result in a warning and may lead to a deduction in participation grades. Use of a phone either to take pictures or to send/receive phone calls, text messages, emails or any other purposes during class is impolite, inappropriate and hence prohibited. Faculty determines whether laptops will be allowed in class. The use of a laptop, tablets or of cell phones is prohibited during all tests and exams, unless otherwise specified by your instructor.
