1/3 New episode of #PolicyImplications with Jacob Kirkegaard. We discuss what Europe has actually built since 2022: the EU has become essential on money, sanctions, coordination, and long-term support for UA. But EU defence future increasingly runs through UA. Link: tinyurl.com/5hfs7u9p

1/4 Very happy to share my new paper with Oleg Badunenko. We study decentralization — one of UA’s most important and successful reforms. It gave local communities fiscal autonomy, responsibility, and the capacity to respond to local needs. Link: shorturl.at/wOsPt #EconSky #EconTwitter

🎙️ New episode of Policy Implications. I spoke with @dariia.bsky.social about her new paper on UA migration to PL and what it tells us about migration and voting. The findings challenge the simple idea that more migration automatically boosts the far right. Listen here: tinyurl.com/52ar3c7k

1/ Migration between UA and PL is often framed as a story of crisis, pressure, and displacement. But it is also a story about skills, talent, and long-term economic strategy. In the new episode of Policy Implications, I spoke with Ivanna Kyliushyk about exactly that. Link: tinyurl.com/2zz84p5r

Great opportunity for young economists to get feedback and potentially get your research published in Eastern European Economics journal.

Spoke with @tvpworld.bsky.social about the #Russian #economy & factors behind its #collapse. Big thanks to Jan Darasz for the insightful discussion on how #sanctions, #energy markets, and #tech constraints shape Russia’s future. Link: www.youtube.com/watch?v=Q4sA...
