Slimane, Sarra Ben, "Effects of Discretionary Fiscal Policy in Tunisia: A SVAR Model Investigation". Both SVAR and VECM models have the potential to improve forecast performance if the hard restrictions they impose on the model are at least approximately correct, but they have seen relatively little use in forecasting applications, in particular in their Bayesian flavor.

For the so-called AB model, set out by Amisano and Giannini (1997) in the structural VAR framework, we have, for instance, D = A−1B. Then we estimate by LS the model Yt = + Xt + t In the population = 0 and = 0, since Xt and Yt are independent. The GVAR approach provides a useful and practical way of building such a model, and, although developed originally as a tool for credit risk analysis, it soon became apparent that it has numerous other applications. In particular, a SVAR model with a long–run restriction yields biased estimated responses even in the case where the VAR model does not display non–fundamentalness.

The require inputs are the set of constraints to be placed on the elements of the A and B matrices so that Vec(A) = s A. First, their SVAR model does not include the short-run policy rate. So in one sentence, in a SVAR restrictions are imposed on the variable dynamics beforehand and the rest is considered exogenous shocks, while in the VAR the coeffients of the lags are identified. every aspect of the model as truth A less ambitious approach is to focus on just some "key properties" both in the model and in the data What properties? means, standard deviations, cross-correlations but propagation of shocks is key aspect of economic models =)autocovariance say something about this but not in the most intuitive way. Section 5 describes the calibration of the nonestimated structural parameters of the model. from the Cowles Commission approach, and similarly to the Granger-VAR model, the data generating process is generally enough articulated so that time series variables are not dis-tinguished a priori between exogenous and endogenous.
