France: What effects of an expansionary fiscal policy made possible by a fall in interest on public debt?

A fall in interest on public debt thanks to a fall in interest rates makes it possible to conduct a more expansionary fiscal policy with an increase in the primary fiscal deficit (excluding interest on debt) . We will here take the example of France. Is this more expansionary fiscal policy stimulating demand? It has to be pointed out that, simultaneously: Government transfer payments are increasing or tax es are cut; The interest received by savers is falling. So we should not forget that the overall effect is expansionary only if savers’ propensity to consume is lower than that of the beneficiaries of government transfer payments or tax cuts .
