The paper
This paper develops the Air Connectivity Index, a measure of how well countries connect to the global air transport network. It captures the strength and breadth of connections, including the role of hubs and indirect links.
Research findings
- Connectivity depends on the network as a whole: a strong link to one destination does not give a country the same reach as strong links to many markets.
- Better air connectivity is associated with more liberal air-services policies and greater specialization in parts-and-components exports.
Policy takeaways
- Assess network access, connection quality, and indirect routes alongside the number of direct flights.
- Consider aviation market access and transport policy when diagnosing barriers to participation in time-sensitive trade and production networks.
