## List of courses

#### Location: Ecole Polytechnique, Palaiseau.

### ECO_51633_EP Preparatory course in Mathematics, Probability and Statistics (end of August, beginning of September)

**Mathematics, Optimization, Probability, and Statistical Inference36 hours**

**Nicolas Vieille**, **Michele Fabi**

– Basic calculus.

– Linear algebra.

- Static and dynamic optimization.

– Basic probability theory.

– Statistical inference.

### ECO_51432_EP Preparatory course in Econometrics

**Introduction to R for Economics8 hours**

**Arnault Chatelain**

This crash course is intended to introduce students to the programming language R. The goal is to teach students how to implement simple data science/econometrics projects on R and where to look for for more advanced uses.

We will start with a general overview of R as a programming language and how to install and work with it on one’s own laptop. We will then introduce the tidyverse, a collection of R packages for data science. We will conclude with touching upon a few popular econometrics packages in R.

At the end of the course the student will know:

– What R is

– How to use it for data science/econometrics tasks

### Over the whole year

### ECO_50P11_EP Project in Applied or Theoretical Economics

Coordinators: **Arne Uhlendorff**

The applied project ECO511 is a year-long supervised research effort by students designed to complement formal course work. The point of the project is for students to apply what they have learned in class to a real-world research problem. Topics can range in both subject matter and methodology (both empirical and applied theory are possible). Topics are proposed by supervisors at the beginning of the year in a catalogue. Students form groups of twos or threes and then submit ordered rankings of desired topics. Students are then matched to supervisors/topics and work begins. Supervisors should provide some guidance in terms of methodology and data, but students should retain the freedom to be creative in addressing the question. Students are required to submit a midterm report in December describing progress to date. A final written report is due in March, which the students then defend to the supervisor in an oral exam.

### Advanced Econometrics I - ECO_51652_EP 5 ECTS

**The Linear Regression Model and Extensions40 hours**

**Sebastien Roux, Thierry Kamionka**

In this course we introduce the linear regression model and its theoretical foundations. We present and discuss the methods to estimate such models, i-e to define the parameters of interest, estimate them and test their statistical significance, under different sets of assumptions (homoskedasticity or heteroscedasticity, exogeneity or endogeneity), specifications (simple or multiple regression) or types of data (cross-sectional, panel data, time series).

Outline:

1. Introduction to econometrics

2. The Simple Regression Model

3. Multiple Regression Analysis:

A. Estimation

B. Inference

C. Asymptotics

4. Qualitative Information in Linear Regression

5. Heteroskedasticity

6. Repeated Cross Section and Panel Data

7. Instrumental Variables
