Skrócony opis: |
(tylko po angielsku) BA level. The objective of this course is to teach students econometric methods, their theoretical properties and most important applications. Lectures will be illustrated with simple empirical examples. Course covers the estimation of parameters in Classical Linear Regression Model with Ordinary Least Squares and some extensions like Generalized Least Squares and robust estimation of variance matrix. In this context the most important element of statistical inference discussed: estimation, parameter interpretation, test the statistical hypotesis, and diagnostics of the estimated model. Upon learning the course material student should be able to make inferences about relations between variables in cross section sample. Problem sessions are to teach students how to formulate an econometric model, how to estimate it with STATA package and how to inteprete the results. Course is intended for 3rd year students. Final grading is based on grades from problem sessions and written exam. |

(tylko po angielsku) The course main objective is to teach students the basic methods used in empirical research in economics. The lecture is to make student familiar with OLS estimator, statistical inference in OLS, diagnostic tests, autocorrelation and heteroscedasticity, simultaneity/endogeneity problem, omitted variable problem, identification of parameters, GLS estimator. The problem sessions are intended to teach students the practical aspects of the applications of the econometric tools mentioned above. Upon completion of the course student should be able estimate himself linear economic model and to interpret the interrelations between analyzed variables with estimated coefficients of the model. Student should also be able to identify the variables whose influence on other variables is statistically significant and to test the validity of statistical and functional assumption upon which the model is based.

Metody i kryteria oceniania: |
(tylko po angielsku) Final grade is a weighted average of the grades from written exam and problem sessions with weights 2/3 and 1/3 respectively. Students who failed the problem sessions are not permitted to take the exam. Written exam takes 90 min and consists of 4 theoretical questions, 2 modified exercises similar to the problems in the problem set, and 1 exercise not included in problem set. Theoretical questions are modified versions of the questions given at the end of each lecture. In order to pass the exam student has to solve at least one exercise and answer 2 theoretical questions. Grading of problem sessions is based in 40% on final test, in 20% on quizzes and activity and in 40% on the grade from the empirical model. The autors of the best model submitted will be exempted from writing the exam but under condition that they have at least 4 from the final test. Problem sessions are obligatory. |
