Abstract
This article quantifies the effects of supply chains disruptions on inflation in European economies. We apply the local projection method in a panel framework and estimate responses of nine measures of consumer and producer inflation to shortages in materials and equipment reported by enterprises in the business surveys conducted by the European Commission. We find that supply chains disruptions are proinflationary for all considered measures of inflation, and a larger effect can be observed for inflation of prices of goods rather than services. The peak of impulse responses can be observed 4-6 quarters after shock, while the effect usually dies out after 8-12 quarters. The forecast error variance decomposition (FEVD) suggests that supply chain disruptions are much more important in explaining inflation changes at medium- rather than short-run forecast horizon. Moreover, supply chain shocks seem to matter relatively more for the variance of inflation of consumer prices of goods than for other measures of inflation. Interestingly, the positive estimates of the impact of supply chains disruptions on inflation can be related mainly to the period corresponding with the COVID-19 pandemics as well as the full-scale invasion of Ukraine and may exhibit asymmetric or regime-switching nature.
