The Analytics of SVARs: A Unified Framework to Measure Fiscal Multipliers

Abstract: Does scal policy stimulate output? SVARs have been used to address this question but no stylized facts have emerged. We derive analytical relationships between the output elasticities of scal variables and scal multipliers. We show that standard identi cation schemes imply different priors on elasticities, generating a large dispersion in multiplier estimates. We then use extra-model information to narrow the set of empirically plausible elasticities, allowing for sharper inference on multipliers. Our results … Show more

“…12 This identification strategy differs from the pure sign restriction identification approach, in that both of our identification schemes identify a single structural VAR specification, rather than a set of models (Caldara and Kamps, 2012;Arias et al, 2013).…”

“…A similar identification strategy to the one used in this paper is employed by Caldara and Kamps (2012), who identify tax and government spending shocks by putting discipline on the systematic component of fiscal policy. They combine zero restrictions with empirically plausible bounds on the output elasticities of fiscal variables.…”

“…Social security adds to progressivity, such that the overall net-revenue budget strongly reacts to a change in GDP. Caldara and Kamps (2012) show that within a reasonable range of α τ y , not even the sign of the resulting multiplier can be robustly estimated, such that both negative and large positive multipliers can occur. The very nature of the BP approach for estimating revenue multipliers, however, rests upon the assumption of a certain value of α τ y that is imposed as a scalar without taking into account likely uncertainty around this figure.…”
