Course outline

  • Probability Theory and Distribution Theory: Joint distribution, Marginal distribution and Bounded distribution. Multivariate Normal Distribution.
  • The Linear Regression Model and the Least Squares Method.
  • The Least Squares Estimator: properties in finite samples and asymptotic properties. Confidence intervals for estimates and for predictions. Data problems (Multicollinearity, measurement errors, outliers).
  • Hypothesis Testing and Model Selection: methodological approaches (Wald criterion, constrained estimation vs. unconstrained estimation). Asymptotic tests. Non-linear constraint tests (Delta method).
  • Econometric Model Specification: Methodological approaches to deal with specification error
  • Correlated form and nonlinearities: Use of dummy variables, categorical variables, nonlinearity in explanatory variables (partial linear regression, nonlinear functional forms, variable interactions), structural change.
  • Endogeneity of explanatory variables and estimator of auxiliary variables: Common causes of endogeneity. Structural models and reduced form equations. Statistical tests for selecting the appropriate estimator.
  • Heteroskedasticity in errors: Forms of heteroskedasticity. Generalized Least Squares Method. Statistical tests of heteroscedasticity. Estimation of models with heteroscedastic errors
  • Autocorrelation in errors: Forms and causes of autocorrelation. Statistical tests of autocorrelation.  Estimation of models with autocorrelation.
  • Systems of Equations: Seemingly unrelated equations and the Generalized Least Squares Method. Structural form, the identification problem and estimation methods.

Assessment

Written assignment-examination in Greek (handed in before the written exams) and written exams after the end of the semester as well as a re-examination in September. The examination paper and the written examinations are of equal value. The answer to each question will receive a certain number of points explicitly specified.
