ENAt the aggregate level, I find that the euro changeover did not lead to a significant change in the overall inflation rate between 2015 and 2019 in Lithuania. When the measures are diversified, however, some inflationary effects emerge in sub-categories. I therefore analyze this heterogeneity at the disaggregated level using a large sample of prices that constitutes the CPI from 2010 to 2018. I show that significant price changes have been confined to the low-weighted components of the HICP. This explains why a spike in the overall price level did not occur at the time of the changeover. Keywords: Euro changeover, synthetic difference-in-differences, regression discontinuity in time, price changes. [From the publication]
