Irakasgaiaren azalpena eta testuingurua

Econometrics is concerned with how to use statistical methods and procedures for economic

data. Econometrics techniques have been increasingly used in macroeconomics and applied

microeconomics.



The goal of this course is to provide students with advanced knowledge and tools to conduct their own empirical research in economics, to evaluate government and business policies, to perform forecasting and to use the computer as a tool for regression analysis. Students will be provided with the required tools for the appropriate data analysis they will take on in the different courses within this master program, as well as in their final master thesis.



This course emphasizes both the theoretical and the practical aspects of statistical analysis, focusing on techniques for estimating econometric models of various kinds and for conducting tests of hypotheses of interest to economists. The goal is to help you develop a solid theoretical background in advanced level econometrics, the ability to implement the techniques and to critique empirical studies in economics.



We will develop techniques to handle common econometric problems that arise when working with economic data including heteroskedasticity, autocorrelation, endogeneity, selection bias, misspecification, and measurement errors. We will expand the kinds of data we can analyse by exploring the topics of panel data and binary response.



The course is designed to train students to explore a dataset, write code to analyze relationships and to test hypotheses about some economic phenomenon. Working with data and implementing econometric software is integrated into every aspect of the course including lecture, problem sets and exams. Students are introduced to the statistical package Stata and R. Different types of empirical data sets are introduced, and students are shown how to apply various estimation techniques and testing procedures in practice.



After completion of this course students should be able to perform tasks of data collection, modelling of econometrics relationships, estimating and testing of the model, and interpreting and using the estimation results.



While the course is ambitious in terms of its coverage of technical topics, equal importance is attached to the development of an intuitive understanding of the material that will allow these skills to be utilized effectively and creatively, and to give participants the foundation for understanding specialized applications through self-study with confidence when needed.



Teaching Methodology:



The teaching methodology will be based on lecture type classes, computer software classes and discussion seminars. In the lecture type classes the theoretical contents of the course will be introduced and, in addition, students’ participation will be actively motivated by using take-home exercises. In the computer software exercise type classes, both the students and the professor will solve real data set exercises that will help illustrate the theoretical contents described in the lectures. In the discussion seminars, the professor and the students will actively discuss over practical real settings in the context of some economic process or system.

The expected learning outcomes include familiarization with methods of data analysis including estimation methods and regression analysis, ability to communicate the understanding of data analysis, understanding how economic theories may be used to create testable hypotheses using empirical data and econometrics, examination of the limitations of econometrics and their applications on society. Moreover, the students will learn how to apply statistical-econometric methods for analysis and evaluation of economic policies at a public or private, local, national or international level. They will be also able to carry out empirical work and to choose appropriate statistical-econometric software to carry out quantitative analysis to be presented in high quality professional reports.

Ohiko deialdia: orientazioak eta uko egitea

The final grade for this course will be based on homework exercises students will have to do during the whole class period, on final examination, as well as on individual’s student class participation. Therefore, grades for the course will be based on:



- Homework (4 problem sets): 15%

- Class participation: 5%

- Final exam: 80%



Homework



There will be four problem sets in total. Students may work in groups, but each member of a group should submit her own write-up. In the case of group collaboration, you are required to write down the names of your group members. The group size should not exceed three students.



The evaluation will preferably be in-classroom. If this is not possible, the final exam will be taken using the services available at Egela. The student will have a limited time to download the final exam form from Egela and upload the solution to that platform (preferably in pdf and in any case in a perfectly legible format to enable evaluation). This exam is individual, so in order to ensure this aspect of the exam the use of webcam and an oral interview for verification of the answers might be requested.
