Course Description

Modern tools in time series analysis have become increasingly popular over the last decades in agricultural economics and rural development studies. This course will give an overview of the methods in these fields from an applied econometrics perspective. The significance and the advances in these fields have recently found their peak in honoring the work of the two most known researchers in time series analysis, namely Robert F. Engle and Clive W. Granger, by the Nobel Prize Committee in 2003. Thus, in this course we try to bridge the gap between standard introductory econometrics at the MSc level and modern time series techniques as used in concurrent publications in the AgEcon literature by presenting some theoretical background of these methods and illustrating applications in agricultural economics in order to enable participating PhD students to apply these tools in their research.
