Unexpected shocks in cargo throughputs between U.S. airports impact global trade.
The article explores how cargo traffic between major U.S. airports interacts. The researchers used a method called variance decomposition to see how much unexpected change in cargo traffic at one airport is caused by itself versus other airports. They also used impulse response analysis to see how a sudden change in one airport's cargo traffic affects itself and other airports over time. The results help us understand which airports have the biggest impact on overall cargo traffic variations and how these impacts evolve over time.
