AbstractIn the European Monetary Union (EMU), monetary policy is determined by the European Central Bank (ECB). This arrangement can give rise to certain national economic imbalances that may potentially be addressed through national policies. Traditionally, fiscal policy has been the primary tool to correct these imbalances. However, following the global financial crisis (GFC), a new policy tool has emerged: national macroprudential policies, which aim to mitigate financial risks. This situation raises an intriguing research question: How do macroprudential and fiscal policies interact? Through their influence on real interest rates and economic activity, discretionary macroprudential policies can impact the trajectory of public debt and may necessitate fiscal adjustments, such as tax rate increases, to stabilize the public debt-to-GDP ratio. In a monetary union, a domestic macroprudential shock generates significant cross-border financial effects and also influences the fiscal stance of foreign countries. Furthermore, discretionary government spending policies have an impact on housing prices and households debt. Therefore, the responsiveness of macroprudential policy to changes in housing prices affects the fiscal multiplier.
