We investigate whether the macroeconomic effects of government spending shocks vary with the level of uncertainty. Using postwar US data and a Self-Exciting Interacted VAR (SEIVAR) model, we find that fiscal spending has positive output effects in tranquil times but is contractionary during...

Helicopter money has once been proposed as a theoretical thought experiment by Milton Friedman in order to elucidate the effect of money injections into the macroeconomy over time. However, some Euro area member states nowadays consider helicopter money, i.e. permanent Quantitative Easing (QE),...

There is much debate about the usefulness of the neoclassical growth model for assessing the macro-economic impact of fiscal shocks. We test the theory using data from World War II, which is by far the largest fiscal shock in the history of the United States. We take observed changes in fiscal...
