PhD – 38th cycle – Thematic fields – Econometrics

Econometrics

Doctoral School in Economics

Department of Economics and Social Sciences, Marche Polytechnic University

Course description:

The Econometrics course will be organized in 3 blocks. The first block (21 hours) will present an advanced treatment of econometric theory and principles of estimation and inference in linear regression models, focusing also on maximum likelihood estimation, generalized methods of moments, and heteroskedasticity. In the second block (21 hours), students will study the estimation of nonlinear regression models, notably limited dependent variable models. The third block (21 hours) will present models for time series data. Further 25 hours of computer tutorials will be aimed at developing analytical skills using Gretl (http://gretl.sourceforge.net ).

Learning outcomes:

  • Development of analytical skills so that students can evaluate critically the econometric outputs in the economic literature and correctly interpret them.
  • Development of analytical and technical skills so that students can design proper econometric model to answer their research questions.
  • Development of computer programming skills so that students can estimate sophisticated and state-of-art econometric models.

Prerequisites:

Students should have knowledge, at least at undergraduate level, of the following topics:

  • Scope of Econometrics, the structure of economic data.
  • Causality and the notion of ceteris paribus in econometrics.
  • Definition of the simple linear regression model and its interpretation.
  • Ordinary Least Squares (OLS) estimates and OLS properties.
  • Interpretation of OLS estimates.
  • Multiple regression analysis: many independent variables in the linear regression model.
  • OLS estimates and their interpretation with multiple regressors.
  • Inference in multiple regression analysis.
  • The Gauss-Markov theorem.
  • Testing hypothesis about a single parameter.
  • Testing hypothesis about multiple linear restrictions.
  • OLS asymptotic.
  • Goodness-of-fit measures.
  • Linear models (in the parameters) with quadratics and/or logarithms of the regressors.
  • Linear models with interaction terms.
  • Linear models with qualitative independent variables.
  • Heteroskedasticity: testing and robust inference.
  • Misspecification: functional form misspecification, omitted variables, measurement error.
  • Instrumental variables estimation.


These topics are in chapters 1 to 9 and 15 of “Introductory Econometrics: A Modern Approach” (Wooldridge, 7th edition, 2015). Alternatively, they can be found in chapters 1-9 and 12 of “Introduction to Econometrics” (Stock and Watson, 3rd edition, 2015). These textbooks are for undergraduate economics students who have taken a course of introductory probability and statistics.

Exam:

At the end of the course, students will be assigned a take-home exam on the second block (1/3 of the final grade) with deadline on 4 (date to be confirmed) January 2023 and there will be an open book written exam on the other blocks (2/3 of the final grade) on the morning of Monday 9 (day to be confirmed) January 2023. On Monday afternoon 9 (day to be confirmed) January 2023, students will be asked to orally explain what they did in the take home exam.
In case of resit, the resit will be an open book written exams on all the blocks.

Lecturers:

  • Lecturer of 1st block: Claudia Pigini
  • Lecturer of 2nd block: Matteo Picchio
  • Lecturer of 3rd block: Giulio Palomba
  • Lecturers of computer tutorials: Luca Pedini e Francesco Valentini
