Summer School on Mathematical Methods in Finance and Economy
31/May – 04/June/2010
Hanoi Center for Financial and Industrial Mathematics
Hanoi National University of Education
Graduate students and researchers in finance, economics, and mathematics
People working in the financial industry (investment, insurance, …)
This School will consist of 4 main intensive minicourses (about 6 hours per course), computer sessions, and some research talks.
The four minicourses are:
Time Series Applied to Finance, by Anne Van Hems (Professor at Toulouse Business School)
Non-Parametric Models With Applications To Production Frontiers, by Michel Simoni (Research Director at INRA)
Scoring, by Christine Thomas-Agnan (Professor at Toulouse School of Economics)
Quantitative Portfolio Management, by Nguyen Tien Zung (Professor at Toulouse Institute of Mathematics, and Scientific Director of HCFIM)
Computer sessions will be animated by CNRS research engineer Thibault Laurent
Detailed description of the courses
Course: SCORING (Christine Thomas-Agnan)
Part I: Introduction
- What is scoring ?
- Background on linear regression models
- Generalized linear regression models
Part II: Logistic regression
- Fundamental assumption – Odds

Course: Time series applied to Finance(Anne Vanhems)
The objective of this course is to gain a working knowledge of time series and forecasting methods as applied in economics, engineering and finance. The purpose is to study techniques for drawing inferences from time series. After an appropriate family of models has been chosen, it is then possible to estimate parameters, check for goodness of fit to the data, and possibly to use the fitted model to enhance our understanding of the mechanism generating the series.
After recalling some basic notions in statistics and modeling, we will present the main time series models: ARMA, SARIMA, ARCH, GARCH
Outline of the course:
1) Introduction to Time-series Analysis and stochastic processes
2) Stationnarity of a process and ARMA modeling
3) Box-Jenkins methodology: identification, estimation and testing
4) Times series in finance and conditional heteroscedastic models: ARCH and GARCH
It is important for this course to already know the background on linear regression models, linear projection of Hilbert spaces, maximum likelihood estimation and standard testing hypothesis.

Course: Nonparametric Models with Applications to Production Frontiers
(Michel Simioni, Toulouse School of Economics, INRA-GREMAQ)
The approach of production frontiers is an effort to define empirically an envelopment of production data. This approach is based on the conventional microecomic theory paradigm, assuming that producers optimize by no wasting resources in a systematic way, i.e. producers operate somewhere on the boundary of their production possibility sets, namely the production frontier. Empirical evidence shows that not all producers succeed in all circumstances. Hence, it is important to analyze the degree to which producers fail to optimize and the extent of departures from technical and economic efficiency. The aim of the course is thus to provide an overview of nonparametric methods used in production frontier estimation and efficiency measurement.

The economic model
A taxonomy of production frontier models
The nonparametric envelopment estimators:
