Abstract

Cointegrated and non-cointegrated processes from economic and econometric point of view, based on the time and frequency domain will be presented. Standard tests for cointegrated times series will be discussed as well as their advantages and drawbacks in financial area. In addition to the standard methods, recent methodologies based on the frequency domain will be introduced. The methods will be discussed for multivariate time series with short and long memory properties. Some robust tests will also be presented. The concepts and definitions will be motivated by some real financial time series.
