Figure 2 describes the mobilization of the real exchange rate (REER) around long-term equilibrium position. Combined with the level of the real exchange rate misalignment, can see the general trend of the exchange rate during the study was divided into two periods: from the 1st quarter, 1997-quarterly 1/2011 and 2/2011 quarter-4th quarter/2014. In the first stage, VND was too low compared to the real value, that is, the larger the EREER REER, a peak in Q2, 1997, was as low as USD 21.1%. The most stable period of falling rates in 2000, when the level of distortions is only around 1%, REER close to balance position and always tend to asymptotically. The last phase of the study period, from Q2/2011-4th quarter/2014, real exchange rates under the opposite trend, the USD was high compared to the actual value, the peak in quarter 1/2014, USD was as high as 6.7% and as of the 4th quarter 2014, USD was high as more than 4.8%.2.2 results from models of regression itself according to the vector (VAR)Because the macro variables all have integrated level is 1, meaning I (1), while VAR models require all variables to have to stop, I (0), to avoid spurious regression. So, all of the original background economic variables need to take differential form of degree 1.Because quarterly data string quite short, therefore, research conducted in the late model ranks are always VAR is 1, i.e. VAR (1). Check out about stability of VAR models (Figure 1.a) prove that the completely stable models that can be used in analysis and forecasting.Research conducted by the decay of variance (VDF) in VAR models to crawls the variability of real exchange rate (REER) relatively over time by other shocks. However, a note is the sort order of the variables in the matrix Cholesky triangle will affect the entire results when conducting calculate VDF and IRFs. In this study, the order of the variables are arranged as follows: d (RR), d (lnM2), d (lnOPEN), d (lnREER), d (lnPROD), d (lnNFA). This order was based on the attached reference by d (lnREER), the variables behind the real rate implies that there is no immediate impact to the real rates that are after the late period, the variables standing will impact real rates right in the first period.
