Triggering competition in the Spanish airline market: The role of airport capacity and low-cost carriers

We analyze the influence of increases in airport capacity and the entry of low-cost carriers on airline competition. We use parametric and non-parametric techniques to analyze a sample of Spanish routes. We find that capacity increases in large airports produce more competitive airline conduct only in routes departing from non-hub airports. Also, we find that the natural monopoly threshold decreases with time. Finally, low-cost carriers have a moderate but still significant effect on prices and increase alternatives even in low-density routes.
