The global component of inflation volatility

open access: yesJournal of Applied Econometrics, 2018
SummaryGlobal developments play an important role for domestic inflation rates. Earlier literature has found that a substantial amount of the variation in a large set of national inflation rates can be explained by a single global factor. However, inflation volatility has been typically neglected, although it is clearly relevant both from a policy ...
