Combining monetary and fiscal policy in an SVAR for a small open economy

This paper combines a monetary structural vector-autoregression (SVAR) with a fiscal SVAR for Poland. Fiscal foresight, in the form of implementation lags, is accounted for with respect to both discretionary government spending and tax changes. We demonstrate the importance of combining monetary and fiscal transmission mechanisms. However, ignoring fiscal foresight has no statistically significant effects. We calculate an initial government spending multiplier of 0.14, which later peaks at 0.48. The tax multiplier is close to zero. We also find that monetary policy in Poland transmits mainly through the real sector, that is through real GDP and the real exchange rate.
