The most fertile areas of contemporary time series research concerns multiequation models. The vector autoregressive (VAR) model is the multivariate counter part of the univariate autoregressive model. A VAR model can be used in examining the relationships among a set of variables. The estimates of the parameters of the VAR model can be used for forecasting purposes. Forecasting with a VAR is a multivariable extension of forecasting using a simple autoregression. The VAR analysis tools such as Granger Causality tests, Impulse Response Analysis and Variance Decomposition models can be used in establishing relationships among economic variables; and in the formulation of structured economic models. In the present study a Two-Equations VAR model has been specified and stability conditions have been derived. Using Lag operators, the Two-Equations VAR model has been expressed in terms of Lag operators. This specification facilitates to study further inferential aspects of the VAR model for time series data analysis.Pages: 538-548 | Views: 499 | Downloads: 7Download Full Article: Click Here
