First, we will introduce the idea of econometric model. This model must take into account the special features of economic data. We will focus on the ideas of causality and ceteris paribus analysis, arising from the correct interpretation of these models. From a formal viewpoint, the initial step towards an appropriate conceptual framework will be to introduce the simple regression model. Here, we will study the basic assumptions, interpretation of parameters of interest, ordinary least squares estimation and statistical properties of the estimators.

The second building block of the course is the study of the general regression model. We will analyze its basic properties, focusing on the motivation behind multivariate regression, stressing its usefulness over the bivariate framework which characterizes the simple regression model. Again, we will study in this more general framework the basic assumptions, interpretation of parameters of interest, ordinary least squares estimation and statistical properties of the estimators.

In the last part of the course, we will study different aspects related to the general regression model. First, we will analyze the consequences of the violation of basic assumptions (functional form and specification, heteroskedasticity, autocorrelation). Next, we will introduce the issue of endogeneity, its relation with the instrumental variables estimator (emphasizing the search for appropriate instruments in economics) and a brief discussion of this problem in the context of systems of equations. The course will end up with a brief introduction on qualitative information variables, focusing on dummy variables and on the linear probability model.

CG07. Capacity to solve problems.

CG09. Capacity to work in teams.

CG16. Capacity to work under pressure.

CG17. Capacity to self-learning.

CE02. Identify relevant economic information sources.

CE03. Derive from micro and macroeconomic data relevant information impossible to assess by non-specialists.

CE04. Use of professional criteria in the economic analysis, mainly those criteria based on technical tools.

At the end of the course, the student must be able to translate into mathematical language specific issues from macroeconomics and microeconomics by means of econometric models. Additionally, the student must be able to use the econometric software Gretl and extract conclusions from the estimated models.
