B030707 - MOD.1 MICROECONOMETRICS

English

At the end of the course, students will be able to select the most appropriate modelling to technique for an array of data types. They will also be able to comfortably select the best model specification, conduct robustness checks and statistical tests. Students will be able to interpret and discuss the empirical results both in terms of their statistical implications and the implications they have for economic, financial and social theories.

This course develops models and techniques for analysing cross-sectional and panel data encountered in microeconometric analysis. Binary data, count data, duration, panel data and multinomial data models are covered. The course will also cover maximum likelihood, quasi-maximum likelihood and the generalized method of moments estimation techniques: used to estimate the parameters of the models’ covered. The focus is on applied analysis.

Econometrics.

Lectures and walk-through simple empirical case studies.

Written exam consisting of:
- theoretical questions requiring derivations and/or a few computations
- empirical component requiring the use of some statistical package to carry out the estimation and analysis of simple case studies
