Prerequisiti
Metodi didattici
Lezioni frontali. Esercizi individuali e di gruppo con correzione in aula. Predisposizione del materiale didattico (testi e files di varia tipologia) nella pagina e-learning del corso.
Modalità di verifica dell'apprendimento
Esame finale scritto (6 domande di cui 3 esercizi; ciascuna domanda è suddivisa in singole parti). Al termine del primo modulo (circa 45 h di lezione frontale) è prevista una prova intermedia relativa al programma trattato sino a quel momento a lezione. Il superamento della prova intermedia (con votazione tra 0 e 16; minimo 9) implica limitazione del contenuto della prova finale alla sola seconda parte del corso (sempre con votazione compresa tra 0 e 16; minimo 9). La prova intermedia non è obbligatoria. In sua assenza la/lo studentessa/studente sostiene la prova completa relativa ad entrambe le parti/moduli (votazione compresa tra 0 e 32=30 con lode; minimo 18).
Gli studenti non frequentanti non possono accedere alla prova intermedia e devono sostenere la prova completa.

Learning objectives
The course will:
a) offer basic and specialized knowledge on the Reasons, Instruments and Effects of public intervention in the economies of contemporary capitalist societies.
b) enable the student to critically evaluate the policies that reduced the aforementioned intervention implemented in various countries in recent years and to analyze the effects of the consequent elimination or privatization of the activities previously carried out by the public sector.
c) allow the students to acquire professional skills in the field of planning and management of public services that still exist.
Contents
The course is organized in two non separated parts (modules).
The first part is called the Economics of Services. It is dedicated to the study of the theory of regulation of public utility services in conditions of both perfect information and information asymmetry. In the latter case, the study will cover both Bayesian and non-Bayesian models of natural monopoly regulation, single-production or multi-product. The main models of oligopoly will then be reviewed and the most widespread forms of regulation of these markets will be examined. This part will be completed with the analysis of the so-called competition for the market achieved through the application of auction mechanisms. Specific cases, relating to sectors such as electricity, gas, telecommunications, etc, will be considered.
The second part is called Economics of regulatory choices and deals with regulatory activities, carried out by applying the rules to protect competition and the market, carried out through the activity of independent authorities. The historical profile of this form of "intervention" and the main guiding criteria for the protection of consumers and producers followed by the Authorities will be examined. Some cases derived from specific rulings of the European and national Anti Trust Authorities will be subsequently discussed.

Prerequisites
A basic training in Microeconomics and a more than sufficient knowledge of the theory of competition, equilibrium and efficiency are required. (Reference text example: H. Varian, Intermediate Microeconomics with Calculus, W. W. Norton & Company – 2014).
The knowledge of the fundamental techniques of elementary calculus (functions, limits, derivatives and integrals, with one or more variables) is very useful (and recommended).
Teaching methods
Frontal lessons. Individual and group exercises with correction in the classroom. Preparation of the didactic material (texts and files of various types) on the e-learning page of the course.
Assessment methods
Final written exam (6 questions of which 3 exercises; each question is divided into individual parts). At the end of the first module (about 45 hours of frontal lessons) there will be an intermediate test relating to the program covered up to that moment in class. Passing the mid-term exam (with a grade between 0 and 16; minimum 9) implies a limitation of the content of the final exam to the second part of the course only (always with a grade between 0 and 16; at least 9). The intermediate test is not compulsory. In her absence, the student / student takes the complete test relating to both parts / modules (grade between 0 and 32 = 30 with honors; minimum 18).
Non-attending students cannot access the intermediate test and must take the final complete test.
