Europe, We Have a Problem! Local Economic Winners and Losers of Border Closures

ABSTRACT In response to COVID‐19, Schengen countries temporarily reintroduced internal border controls, disrupting cross‐border integration. Using this policy change as a natural experiment and monthly nighttime lights data, we estimate the short‐run effects on European municipalities. Municipalities along internal Schengen borders experienced a 3%–4% decline in economic activity relative to interior municipalities, with larger estimated effects when external‐border municipalities form the comparison group. Losses were greater in smaller and less densely populated municipalities and along borders connecting Eastern and Western countries, whereas municipalities along borders within the same broad European region generally experienced smaller declines. The effects also depended on the pre‐pandemic purpose of cross‐border mobility: higher shares of work‐ and business‐related travel, services, and shopping were associated with larger losses, while the results for leisure and social mobility are consistent with greater scope for domestic reallocation of activity. Overall, the findings show that the local consequences of internal border closures depend on municipality characteristics, cross‐border economic asymmetries, and the purpose of mobility.
