Using data to prioritise rebuilding

Ukraine's cities were failing long before the Russian invasion began. Kyiv and Lviv ranked among the 40 most congested cities in the world, yet neither makes the top 100 by population. Ninety per cent of Ukraine's housing stock was built before 1990. Its urban infrastructure was designed for a Soviet economy and never properly adapted for the one that followed. So when reconstruction begins, the question is not simply how to repair what was there: it is whether repairing what was there is the right goal.

Edward Glaeser of Harvard, Martina Kirchberger of Trinity College Dublin, and Andrii Parkhomenko of the University of Southern California argue that the most instructive precedent is not post-USSR Warsaw, or postwar Berlin, it is postwar Tokyo. Firebombed into ruin, Tokyo rebuilt in a way that was strikingly decentralised: master plans quickly abandoned, local communities empowered to combine small lots through land readjustment, and figure it out from the bottom up. Before the war, Ukraine's economic activity was already shifting away from heavy industry and the east, towards services and the west. Reconstruction that concentrates investment where the damage is greatest, rather than where people want to build a new life, would repair the buildings and miss the point.

Research cited in this episode

Ukraine Rapid Damage and Needs Assessment, World Bank Group, European Commission, and UN, 2024. The source of the physical damage figure cited in this episode: approximately $175 billion by the end of 2024, with estimates for end-2025 likely exceeding $200 billion. Some independent projections cited by Glaeser run to $500 billion or above.

The concept of investing-in-investing, referenced by Kirchberger, originates in work by Paul Collier on how resource-rich developing countries can scale up capital investment effectively. It refers to the prior investments in institutions, skills, and capacity that must be made before large-scale capital flows can be productively absorbed. The implication for Ukraine: there is work to do now, before reconstruction begins at scale.

The Tokyo land readjustment model, which Glaeser cited as the most instructive reconstruction precedent, allowed owners of small fragmented lots to pool their land, redevelop it jointly, and receive a share of the new property in exchange for their stake in the old. It enabled large-scale urban reconstruction without central expropriation, and without waiting for government direction. The mechanism remains in active use in Japanese urban planning.

The Solidere reconstruction of central Beirut was raised as a cautionary counterexample: a centralised, top-down rebuild that produced a high-end commercial district with questionable benefit to ordinary Lebanese, and which substantially enriched its private shareholders. The contrast with Tokyo's decentralised model is the episode's sharpest illustration of what reconstruction can and cannot achieve when organised from above.

This episode is the second in a three-part series based on papers presented at the inaugural Economic Policy winter conference, Paris, December 2025.

Episode 1: Yuriy Gorodnichenko and Maurice Obstfeld on the investment and financing challenge: $40 billion a year, debt restructuring as a prerequisite for private capital, and why the number is more achievable than it sounds.

Episode 3: Demobilisation and the labour market: getting soldiers back into work without breaking the economy that kept the country going.
