Competition, Markets and Economic Policy

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.
