Market Signals Under Occupation: Inferring War Expectations and Economic Conditions from Online Microdata in Russia and Ukraine

Abstract

I use high-frequency online data on housing, job postings, and prices in Ukraine, Russian-occupied territories, and Russia to infer war expectations and economic conditions. I link housing prices to beliefs about territorial control: sale prices reflect long-run ownership, while rents capture short-run value, so declines in price-to-rent ratios signal higher perceived probabilities of territorial reversion. Using event studies around sanctions, military developments, and official statements, I identify shifts in expectations. Job postings and online prices provide alternative measures of Russian economic activity and inflation, offering timely indicators where official statistics may be unreliable.

Abstract

We analyze how military events, civilian fatalities, and media coverage influence same-day donations to a major Ukrainian nonprofit providing lethal aid during Russia's invasion of Ukraine. In a unique setting, we exploit random variation in attacks on civilians across time to estimate that one additional civilian fatality causes between $4,354 and $6,015 in same-day donations, and leads to at least $8,169 in cumulative donations. Disentangling the effects of events and media coverage, we estimate that a 1% increase in media mentions of military activity leads to a $2,906 increase in same-day donations and an $8,083 increase in cumulative donations.

Abstract

Europe is collectively the largest supporter of Ukraine’s defense, yet announced aid totals vastly overstate what has been delivered. Applying the item-level methodology of Fedyk et al. (2025) across 30 European donors, we find real delivered value falls well below €130 billion in headline pledges, with delivery rates varying from under 10 percent to over 100 percent across countries. Front-line and Central European states bear disproportionate burdens relative to GDP, while several large Western economies under-deliver relative to both pledges and capacity. We exploit this cross-sectional variation to identify the correlates of follow-through and assess macroeconomic effects on donor economies.

Abstract

Why is war so economically costly? Our answer is that modern war lowers output not only by destroying productive factors, but also by making the surviving economy work less efficiently. Using uniquely comprehensive firm-level data collected during Russia’s full-scale invasion of Ukraine in 2022, we document a dramatic collapse in allocative productivity in Ukraine. To sharpen identification and explore key mechanisms (including the role of war intensity, internal displacement, reallocation, and macroeconomic instability), we exploit spatial heterogeneity across Ukrainian districts and comparisons with Russian aggression in 2014 and the 2008 Global Financial Crisis. Our key policy implication is that restoring allocative efficiency–and preparing institutional arrangements that facilitate rapid reallocation in times of stress–is critical for sustaining economic capacity, defense, and national security.
