“…Privatization of airports, and consequently the fees that they charge, could induce passengers to use other out-of-country airports. Notable is the leakage of Canadian passengers to US airports(Elwakil et al, 2013), and of the Dutch to bordering countries during 2008-2009 when an airport tax was in effect. It would be interesting to explore airport privatization under the added complexity of airport competition (e.g.,Basso and Zhang, 2007b;Forsyth et al, 2010), especially when the two airports are located in different countries, and when airports are congestible (e.g.,Basso and Zhang, 2007b;Benoot et al, 2013).…”
