This short course is thought in English as part of the International Semester that the Faculty of Economics of Pisa started two years ago. It is designed for foreign students, especially Erasmus students attending courses at the Faculty of Economics of Pisa, as well as for Italian undergraduate students registered at the 3-year first level laurea in Economics at the University of Pisa. The course will cover the basic economic issues involved in European integration along with the necessary institutional, legal and historical background. Therefore the course aims mainly at informing students on the process of European Integration. However, it should also help in creating a professional of Economics aware of the European dimension of the activity in this field.
