Aim of the course
The course is divided into two parts. The first takes a microeconomic approach to equip students for understanding the workings of the markets in which firms operate, and the modes of competitive interactions between firms. The themes of innovation and safeguarding correct market competition are examined, in line with the ideas of Industrial Economics.
The second part of the course takes a macroeconomic approach to the key problems of economic policy.
The aim is to illustrate the pathologies that can affect an economic system and the methods and instruments which Economic Policy authorities can use to remedy such problems. The topic areas of unemployment, inflation and public debt are studied, alongside the most important Economic Policy levers, i.e. the monetary and fiscal levers, income policies, and policies for stimulating growth.

Examinations
SECTION 1 – 1ST SEMESTER
There will be a written examination at the end of the course.
Students can choose between two examination methods.
Examination method 1 consists of four topics to be discussed (evaluating whether the proposed statements are True, False, or Uncertain) and two open-ended questions, dealing with the material covered during the lectures.
Examination method 2 covers all the material presented during the lectures, with the exclusion of lessons 4, 13 and 16 of the syllabus. In place of the excluded material, students must attend 4 tutorial sessions (dealing with the same topics covered during the lectures). The exam will consist of four questions to be discussed as in Examination method 1 (evaluating whether the proposed statements are True, False, or Uncertain) and an exercise similar to those done during the tutorial sessions.
 
SECTION II – 2ND SEMESTER
·  There will be only  a written examination at the end of the course.
·  There will be no intermediate progress tests.
·  Students will have the opportunity (optionally) to complete group projects in the form of mini research papers. The grades earned for the optional projects can add up to 3/30 to the result of the written test.
