This paper applies an input–output (I-O) approach and a dynamic computable general equilibrium (CGE) model to examine the economy-wide short- and long-run impacts of an increase in public capital investment in air transport infrastructure. The results of the I-O analysis reveal that air transport has above-average backward linkages with other sectors in the economy, with mining being the most intensive industry in intermediate input demand for air transport. The results of the CGE simulation show that at the macroeconomic level, expanding public air transport stock induces modest growth in GDP, employment, income, consumption, private investment, and trade. The findings show that the estimated impact of air transport investment is lower than estimated in studies on the “multiplier effect” of the investment using partial equilibrium techniques.
