What the study found

Air transport was associated with tourism and economic growth in Tanzania, but the strength and timing of that relationship differed. The study found only a short-run relationship between air transport and economic growth, while the relationship with tourism appeared in both the short and long run.

Why the authors say this matters

The authors conclude that air transport contributes to the economy directly and indirectly through the tourism sector. They suggest the government should take serious actions to expand air transportation.

What the researchers tested

The researchers used an autoregressive distributed lag model, or ARDL, which is a time-series method for examining relationships over time, with 21 years of data from 2000 to 2020. They studied the contribution of air transport to the tourism sector and to economic growth in Tanzania.

What worked and what didn't

For economic growth, the number of passengers carried showed a significant positive contribution in the short run. For tourism receipts, passengers carried increased tourism receipts in the long run, while registered carrier departures increased tourism receipts in the short run and passengers carried decreased tourism receipts in the short run.

What to keep in mind

The abstract does not describe limitations beyond the use of 2000 to 2020 time-series data for Tanzania. The findings are specific to the variables and relationships tested in this study.

Key points

  • The study found a short-run relationship between air transport and economic growth in Tanzania.
  • Air transport and tourism were related in both the short run and the long run.
  • Passengers carried had a significant positive short-run contribution to economic growth.
  • For tourism receipts, passengers carried increased receipts in the long run.
  • Registered carrier departures increased tourism receipts in the short run.
