This teaching unit introduces the role of the public sector in modern market economies, with particular attention to the economic analysis of taxation, public policies for income redistribution, and interventions in the presence of market failures.
The course aims at analyzing public intervention in the economic system through the study of the main fiscal and public spending instruments. The goal is to interpret the issues connected to public economic activity by applying the tools of the welfare economics to assess the efficiency and equity of public intervention.
The course investigates the public intervention in the economic system, through the study of the main fiscal instruments and public spending.
At the end of the teaching unit, the student will be able to: - Describe the main reasons for State intervention in the economy, in relation to real cases discussed during lectures (Dublin Descriptor 1). - Analyze market failures and specific situations that require State intervention (public goods, externalities, information asymmetries), applying concepts to practical examples (Dublin Descriptor 2). - Explain the principles on which the tax system is based and assess the functioning of taxation with respect to societal well-being, through numerical and graphical exercises (Dublin Descriptor 2). - Apply the tools of welfare economics to assess the efficiency and equity of public intervention, by solving problems proposed in class (Dublin Descriptor 2-3). - Evaluate the effect of taxes and subsidies on the choices of taxpayers and firms, interpreting data and case studies (Dublin Descriptor 3). - Analyze the determinants of tax evasion and the impact of enforcement policies, discussing real or simulated cases (Dublin Descriptor 2).

The final exam, lasting 1 hour, is written and divided into two parts. The first part consists of multiple-choice questions; the second part consists of open-ended questions and exercises (open questions on theory, graphical analysis, numerical exercises)
The written exam will assess the learning of the basic concepts covered during the course and the ability to apply knowledge in practical situations by correctly interpreting numerical and graphical examples. Each learning outcome will be verified through specific questions (multiple-choice and open-ended), and the evaluation will consider clarity of exposition, correct use of terminology, and analytical skills.
