Cointegration and EC model

The thesis deals with the concept of cointegration of time series and related error correction model. First, we introduce the basic definitions and theorems that are necessary for understanding the subject of other chapters. Then we focus on the definition of cointegration and the issue of tests for cointegration. Next, we define the error correction model in general in the vector autoregression as well. We will show and prove Granger's representation theorem, which will allow the construction of the EC model in the next section of the chapter. Finally, we apply the written theory to real time series. We perform cointegration tests and construct the relevant EC model.
