What the study found

The study found evidence of economies of scale at airports in Türkiye, meaning unit costs change as airport activity grows. It also found that airport costs are sensitive to passenger volume, while the effect of aircraft movements on unit costs is limited.

Why the authors say this matters

The authors say the findings provide important information for policymakers and airport management. The study suggests the results can help explain airport cost structures and the state of economies of scale in Türkiye.

What the researchers tested

The researchers examined the unit cost structure of 40 airports operating in Türkiye. They used panel data analysis with passenger numbers, aircraft traffic, and airport revenues from 2014 to 2023, and selected a random effects model after the Hausman test.

What worked and what didn't

The random effects model produced statistically significant results. The analysis confirmed economies of scale at airports, found that aircraft movements had a limited impact on unit costs, and showed that higher revenues were associated with higher unit costs.

What to keep in mind

The abstract does not describe specific limitations beyond the study’s focus on 40 airports in Türkiye and the 2014 to 2023 period. No additional caveats are stated in the available summary.

Key points

  • The study found economies of scale at airports in Türkiye.
  • Airport costs were reported to be sensitive to passenger volume.
  • Aircraft movements had a limited impact on unit costs.
  • Higher airport revenues were associated with higher unit costs.
  • The analysis used panel data from 40 Turkish airports covering 2014 to 2023.
