Abstract:
In this paper, we use an open economy DGE model (SIGMA) to assess the quantitative effects of fiscal shocks on the trade balance in the United States. We examine the effects of two alternative fiscal shocks: a rise in government consumption, and a reduction in the labor income tax rate. Our salient finding is that a fiscal deficit has a relatively small effect on the U.S. trade balance, irrespective of whether the source is a spending increase or tax cut. In our benchmark calibration, we find that a rise in the fiscal deficit of one percentage point of GDP induces the trade balance to deteriorate by less than 0.2 percentage point of GDP. Noticeably larger effects are only likely to be elicited under implausibly high values of the short-run trade price elasticity.

Abstract:
Gali's innovative approach of imposing long-run restrictions on a vector autoregression (VAR) to identify the effects of a technology shock has become widely utilized. In this paper, we investigate its reliability through Monte Carlo simulations using calibrated business cycle models. We find it encouraging that the impulse responses derived from applying the Gali methodology to the artificial data generally have the same sign and qualitative pattern as the true responses. However, we find considerable estimation uncertainty about the quantitative impact of a technology shock on macroeconomic variables, and little precision in estimating the contribution of technology shocks to business cycle fluctuations. More generally, our analysis emphasizes that the conditions under which the methodology performs well appear considerably more restrictive than implied by the key identifying assumption, and depend on model structure, the nature of the underlying shocks, and variable selection in the VAR. This cautions against interpreting responses derived from this approach as model-independent stylized.
