International spillovers from U.S. fiscal policy shocks

I estimate the effect of U.S. government spending and tax shocks on Canada, Japan, and the U.K. for the period 1974 through 2007. Spending and tax shocks are identified using sign restrictions on the impulse responses from a vector autoregression (VAR). I find that while spillover effects of expansionary fiscal shocks are not uniform in direction or magnitude across countries, for Canada and Japan they result in economically significant GDP increases over some portion of the response horizon. For all three countries, government spending shocks generally have larger effects than net tax shocks. Altogether, the results support the idea that some countries may benefit significantly from expansionary U.S. fiscal policy
