### Références

The main course reference are the lecture notes available on the course website. They cover all relevant material for the course. In addition, mathematical concepts can be acquired in books, online courses, and other references. There are numerous textbooks on the mathematics for economics and finance. No single book is comprehensive.

The recommended textbooks on optimization are:

• (Good review, basic level) Simon, C. P. and L. Blume, 1994, Mathematics for Economists, Norton, New York.

• (Recommended level; more material than we can cover) Sydsaeter, K., P. Hammond, A. Seierstad, and A. Strom, 2005, Further Mathematics for Economic Analysis, Prentice Hall.

• (Good short book; focused on optimization) Dixit, A. K., 1990, Optimization in Economic Theory, 2nd Edition, Oxford University Press.

• (Good book; focused on optimization) Sundaram, R. K., 1999, A First Course in Optimization Theory, Cambridge University Press.

• (Advanced level) Fuente, A. de la, 2000, Mathematical Methods and Models for Economists, Cambridge: Cambridge University Press.

The recommended textbooks on probability and statistics are:

• (Recommended; more material than we can cover) Casella, G. and R. L. Berger, 2001, Statistical Inference, 2nd edition, Brooks Cole.

• (Good short book; focused on introduction to econometrics) Gallant, A. R., 1997, An Introduction to Econometric Theory, Princeton University Press.

• (Good math and statistics appendix) Green, W., 2010, Econometric Analysis, Princeton University Press.

### Evaluation

#### 1ère tentative

Examen:
Ecrit 3h00 heures
Documentation:
Non autorisée
Calculatrice:
Autorisée avec restrictions
Evaluation:

Your grade will be determined based on the criteria laid out in the syllabus available on the Moodle course website. There will be optional tasks during the semester and a compulsory final exam. The optional tasks yield a bonus on the final grade, that is, the final grade will take into account the optional tasks only if they provide the student a higher grade than the final exam grade.

#### Rattrapage
