Type: Compulsory
ECTS Credits: 9.0 ECTS


Requirements (Subjects that are assumed to be known)
Econometrics I and Econometrics II
The objective of this course is to deal with some important topics in the empirical analysis of micro data (households, firms, etc.). We will study issues in the specification, estimation and testing of different models with cross-sectional and with panel data. The emphasis of the course is both on the econometric techniques and in the economic applications. Therefore, this course will be useful for those interesting in studying these econometric techniques per se, and for those who see the econometric techniques as necessary tools to develop applied work using micro data. The examples of applications will be from wide range of fields: labour economics, health economics, economics of education, Industrial Organization, demand estimation, evaluation of public policies, etc. Prerequisites: Econometrics I and Econometrics II. Students are expected to know well and review before the course GMM, MLE, and other Extremum Estimators. This includes asymptotic properties of these estimators, testing, and selecting optimal instruments (in a GMM setting).

Description of contents: programme
Microeconometrics: 1. Linear Models for Panel Data Introduction and motivation. Review of Static models and control for unobserved heterogeneity: Within-groups, between-groups and Random Effects Methods. Dynamic models. Models with strictly exogenous and predetermined variables. The bias of the within-groups estimator. GMM estimation of dynamic panel data models. Specification tests. Examples of applications of these methods: - I.O.: Identification and Estimation of Production Functions (e.g. Productivity in the telecommunications equipment industry). Olley and Pakes (1996); Ackerberg, Caves and Fraser (2006); and its comparison with Arellano and Bover (1995) and Blundell and Bond (1998, 2000). - Labour and Education Economics: Estimates of the Return to Schooling. Ashenfelter and Krueger (1994) - Labor and Health Economics: ¿Can Pay Regulation Kill? Panel Data Evidence on the Effect of Labor Markets on Hospital Performance¿ Propper and van Reenen (2010) 2. Discrete Choice Models Introduction and motivation. Review of binary choice models for cross sectional data: linear probability models, probit and logit models. Maximum likelihood, semi-parametric, and non- parametric estimation. Interpretation. Multiple choice models: multinomial probit and multinomial logit. Simulated method of moments estimation. Ordered probit. Binary choice models for panel data. Fixed-T solutions: static and dynamic models, random effects and fixed effects approaches to account for unobserved heterogeneity, identification problems and set identified parameters of interest. General solutions to fixed effects estimation (T is not fixed). Limitations of the linear index specification. Structural dynamic discrete choice models and dynamic discrete games: Models, Estimation Methods, and Examples such as studying retirement decisions, occupational choices and career decisions, school drop-outs, patents renewal, estimation of demand and supply curves, effect of number of firms on the entry decision of a new firm, Auctions . Examples of applied papers using these methods: - Health Economics: ¿State dependence and heterogeneity in health using a bias corrected fixed effects estimator¿. J. Carro and A.
