Introduction by the editor

Structural vector autoregressions have become one of the major ways of extracting information about the macro economy. To determine this information, a vector autoregression (VAR) is first fitted to summarize the data and then a structural VAR (SVAR) is proposed whose structural equation errors are taken to be the economic shocks. The parameters of these structural equations are then estimated by utilizing the information in the VAR. The VAR is a reduced form that summarizes the data; the SVAR provides an interpretation of the data. As for any set of structural equations, recovery of the structural equation parameters (shocks) requires the use of identification restrictions that reduce the number of “free” parameters in the structural equations to the number that can be recovered from the information in the reduced form. Recently, a new method for estimating SVARs has arisen that employs sign restrictions upon the impulse responses as a way of identifying shocks (Jon Faust 1998; Harald Uhlig 2005; Fabio Canova and Gianni De Nicoló 2002). Applications of this method have been growing, as seen in the papers listed below. Most of the papers below are reviewed in Fry and Pagan 2010 which examininges this literature in more detail.
