If territorial fragmentation is a problem, is amalgamation a solution? – Ten years later

Over the last decade, municipal territorial amalgamation has occurred in 15 European countries. The same period has seen spectacular progress in research on the relationship between municipal size and the functioning of local governments, as well as the impacts of territorial reforms on economic performance and local democracy. Quasi-experimental designs treating territorial reforms as specific “research laboratories” have constituted an important part of that trend. However, there are still important gaps in the knowledge and the study results are often inconclusive. These observations call for a research agenda for the future.
