Why Decentralised Governance Works: Evidence from Heating Consumption in Ukrainian Buildings

Abstract This paper empirically investigates whether decentralised institutions are more efficient than centralised ones in governing the commons, using a database of heating consumption from 8,839 multi-apartment buildings in Kyiv. The empirical analysis reveals that buildings that switch to homeowner associations (HOAs) reduce their heating consumption compared to those that remain externally governed by municipal or private companies. The first channel for this reduction operates through mitigating the principal-agent problem, allowing HOAs to regulate heating more flexibly during warmer months. The second channel involves investments made through co-financing programmes in which HOAs participate. Such investments significantly reduce heating consumption, unlike unconditional investments financed from the city budget. The estimation results align with the theory of governing the commons, which suggests that local institutions must solve the tragedy of the commons. The paper also explores the reasons why only 18% of buildings transitioned to a local institution despite its higher efficiency.

Go local - get tax compliance and local growth? | with Benedikt Herrmann, Felix Rösel | Draft available upon request

Abstract This paper analyses the local economic and fiscal returns of decentralisation. We analyse the staggered decentralisation of powers and tax revenues to municipal governments in Ukraine between 2015 and 2020. Most importantly, decentralised authorities retain 60% of the personal income tax collected within their jurisdiction. We collect expert‐survey data on regional government support as a plausibly exogenous determinant of selection into decentralisation and use difference‐in‐differences and event‐study estimations. Our results show that decentralisation stimulates economic growth and generates additional tax revenues for local governments. Moreover, the elasticity of tax revenues rises significantly after decentralisation, suggesting higher levels of tax compliance when taxes are used locally. These findings underscore the importance of embedding incentives within systems of fiscal federalism.
