Drivers and spillover effects of inflation : the United States, the euro area, and the United Kingdom

We investigate the drivers of the recent inflation in three currency areas: the United States, the euro area, and the United Kingdom. To do so, we use a VAR set-up to examine the nature of the shocks that underpinned the recent inflation. We apply two methods to calculate shocks -- the standard Cholesky decomposition and a new method that captures more realistic shocks by solving the VAR backwards. We also use spatial modelling to investigate cross-country inflation spillovers. We find the inflationary shocks in the United States are transmitted to the euro area and the United Kingdom in a powerful and consistent way. The euro area transmits inflation to the other regions but to a lesser extent, while the inflation in the United Kingdom has little effect on the other two regions
