Deep dive into beggar-thy-neighbour effects of monetary policy spillovers.

We analyse the effect of the European Central Bank's (ECB) monetary shock spillover and its impact on the European Union's 9 countries outside the euro area (EA) between 2000 and 2020. We use the sign-restricted Bayesian VAR model and subsequent interpretation by plotting the impulse-response functions. Moreover, we investigate both conventional and unconventional monetary policies and its international transmission. The spillover of monetary policy is growing with the openness of economies and the ongoing deepening of integration. The output responds to the EA's monetary shock flexibly and persistently, but there is considerable heterogeneity across countries. We claim that it is essential for central banks outside the EA to monitor and incorporate the ECB's monetary policy spillover into decision-making processes. In particular, the international transmission of the unconventional monetary policy has a fundamental effect on the development of the price level, thus achieving price stability. In the case of implementing a counter-cyclical policy, it is also necessary to monitor conventional policy. However, there is no need to fight the spillover effect since there is no beggar-thy-neighbour problem, i.e., spillover effect works in the same direction in both domestic and foreign country.
