We do have a framework for thinking about this issue: the Mundell-Fleming model. And according to that model (does anyone still learn this stuff?), fiscal contraction in one country under floating exchange rates is in fact contractionary for the world as a whole. The reason is that fiscal contraction leads to lower interest rates, which leads to currency depreciation, which improves the trade balance of the contracting country — partly offsetting the fiscal contraction, but also imposing a contraction on the rest of the world. (Rudi Dornbusch’s 1976 Brookings Paper went through all this.)
