Webbimportant contribution was Sims (1980) and the inception of vector autoregressions (VARs). The VAR methodology offered a powerful new analytical weapon – the impulse response function (IRF). IRFs are used to track the responses of a system‘s variables to impulses of the system‘s shocks. WebbThe vector autoregression (VAR) has been the dominant model in econometrics applied to macroeconomic data starting with Sims (1980). We highlight two features of the vast macroeconomic literature using VARs. First, the most common restriction tested and im-posed in VARs is probably Granger-noncausality.

WebbVector Autoregressions (VARs) have become one of the most popular models in modern macroeconomics since the seminal work by Sims (1980). In recent years, two promi-nent developments have occured in the Baysian VAR literature. First, beginning with Banbura, Giannone, and Reichlin (2010) researchers have been working with large VARs Webbyears ago (Sims, 1980), the basic linear vector autoregressive (VAR) model has been applied in various economic modelling situations and developed further in many ways. … Webb6.
