Obiettivi Formativi
OBIETTIVI FORMATIVI: ll corso fornisce strumenti econometrici per lo studio di modelli strutturali. Gli studenti acquisiscono qualificate competenze metodologiche e professionali nell'ambito dell'economia strutturale. il corso collega la letteratura di modelli econometrici per la valutazione di politiche con quella di stima degli effetti causali.
CONOSCENZA E CAPACITÀ DI COMPRENSIONE: apprendimento di un approccio statistico ed econometrico avanzato. Lo studente sarà in grado di distingure un modello strutturale da uno in forma ridotta e capire quale tecnica econometrica è più idonea nel contesto di analisi.
CAPACITÀ DI APPLICARE CONOSCENZA E COMPRENSIONE: Utilizzazione delle conoscenze e capacita di comprensione delle tecniche di stima su microdati applicate a casi pratici. Le metodologie consentono di poter formulare delle proposte concrete di policy; quanto appreso puo' essere utilizzato nell' ambito della ricerca e per possibili sviluppi lavorativi. Utlizzo di softwares dedicati: R.
AUTONOMIA DI GIUDIZIO: Quanto appreso puo' essere utilizzato per valutare in maniera critica i principali problemi di policy e valutarne l'impatto. Sviluppo di capacita' di analisi di microdati utile ai fini della preparazione di progetti di ricerca. Capacita' di trarre conclusioni rilevanti partendo da problemi e questioni di carattere pratico.
ABILITA' COMUNICATIVE: Saper presentare fatti e meccanismi complessi in maniera rigorosa a interlocutori specialisti e non.
CAPACITÀ DI APPRENDIMENTO: Al termine del corso gli studenti devono avere acquisito la capacita' di saper stimare un modello strutturale e interpretare le stime dei parametri. Gli studenti devono essere in grado di estendere alle loro tesi di laurea le tecniche acquisite continuare a studiare ed elaborare progetti di ricerca in modo autonomo.
Learning Objectives
LEARNING OUTCOMES:
-This course will provide an overview of econometric methodologies used to study and develop structural models.
-Students will gain knowledge on identifying and estimating model parameters based on theoretical economic models.
-The course will exploit the link between the literature of structural econometrics and causal inference in statistics.
-These methodologies will then be applied, for example, in the evaluation of well-known policy programs.
KNOWLEDGE AND UNDERSTANDING:
Learn the main statistical and econometric approaches to identify and estimate structural econometric models.
APPLYING KNOWLEDGE AND UNDERSTANDING:
-Apply knowledge and understanding of the estimation techniques by utilizing microdata in policy evaluation scenarios.
-Applications will be based on widely recognized welfare programs.
-Develop skills in using the following software: R.
MAKING JUDGEMENTS:
-Develop microdata analysis skills useful for preparing research projects.
-Understand the difference between 'structural econometric' and 'reduced form' approaches.
COMMUNICATION SKILLS:
-Learn to present facts, analyze data, and address economic problems rigorously for both specialist and non-specialist audiences.
LEARNING SKILLS:
-Gain the ability to estimate parameters of structural models and interpret economic issues within the context of existing economic theories.
-Apply these research techniques to independently develop research projects and ideas.

Prerequisites
microeconometrics and statistics
Programma
"Man is by nature a social animal... He who lives without society is either a beast or God" (Aristotle - Politics, Book I, Part II).
In economics, the importance of social interactions outside the market is now widely recognized. Individuals share information, learn from each other, and influence one another in various contexts.
The course introduces the game-theoretical foundations of social interaction models and focuses on identifying and structurally estimating model parameters. Social interaction models are a specific case of simultaneous equations models, i.e., statistical models in which dependent variables are jointly determined by other dependent variables along with independent ones. Many economic models are simultaneous in nature as a result of the underlying equilibrium mechanism. A prime example is the estimation of utility parameters within the equilibrium equation system in the economy under social interactions.
