Econometric Assessment Methodology

The Input-Output (I-O) Multiplier Matrix

Airport economic contributions cannot be evaluated solely by counting on-site payroll. Ecquants applies Leontief input-output macroeconomic modeling to trace currency velocity across the wider economic sphere:

• Direct Impact (E_direct): Capital expenditures, ground operations, gate concessions, air traffic handling, and airline station costs.
• Indirect Impact (E_indirect): Intermediary supply purchases: jet fuel refining, inflight catering production, security staffing, and airfreight forwarding.
• Induced Impact (E_induced): The consumption multiplier resulting from direct and indirect aviation employees spending wages on housing, healthcare, education, and consumer goods.
• Catalytic / Trade Growth (E_catalytic): Inbound tourist expenditures and corporate headquarters agglomeration enabled by non-stop long-haul air connectivity.
