Airfreight Transport and Economic Development: An Examination of Causality

The paper examines the potential role that airfreight transport in the US can play in stimulating local and regional economic development. The analysis examines trends in employment and income for metropolitan statistical areas that make use of airfreight services. The focus is on causality, and not on simple correlation, and uses econometric analysis rather than simpler economic multiplier approaches. Granger causality testing based on panel data covering 35 airport and 32 metropolitan statistical areas in the US from 1990 to 2009 indicates that airfreight transport was a positive driver for local economic development. The conclusions focus on the strengths but also the weaknesses of the methodology for assessing causality.
