Inflation expectations proprietiesduring the war: The case of Ukraine

inflation expectations, mutual information, dynamic time warping, warAbstract
This study compares consumer and professional inflation expectations in Ukraine before and during the Russian invasion of Ukraine. We apply entropy-based measures to tackle co-movements of expectations and macro variables (inflation, food inflation, exchange rate and production) and dynamic time warping to assess their forward and backward orientation. The pre-war sample spans from May 2019 to February 2022, and the war sample from March 2022 to December 2024. We expected to find differences between pre-war and wartime samples, as war constitutes a political shock with severe economic consequences. The study confirms the change of expectations: more substantial mutual information with past inflation in most cases, better alignment between professionals and consumers, and a change in the distances between expectations and past or future inflation. This is the first empirical study discussing Ukrainian economic agents’ expectations during the full-scale invasion.
