#### Obiettivi formativi

The course gives an overview of the main econometric tools, with particular emphasis on applications. The course is divided in three parts. The first part provides an introduction to econometrics and a refresher on statistics. The second part presents the standard econometric method (ordinary least squares regression, OLS) and discusses how to tackle its limitations (outliers, collinearity, wrong specification of the functional form, heteroskedasticity and autocorrelation). The third part shows more advanced tools, designed to deal with limited dependent variables (probit, logit) and endogeneity of the explanatory variable (simple instrumental variable estimator, SIV, and generalized instrumental variable estimator, GIVE).
