Spillover effects of the development constraints in London Heathrow Airport
No full textIn this article we assess the growth impact of London Heathrow's development constraints on other airports in the UK. To test the relationship we use a two-stage methodology yielding an estimate of a congestion spillover effect. Our data are passenger traffic from 1990 to 2012 containing both intercontinental and European air traffic. For intercontinental air traffic, our results show high congestion spillover effect between Heathrow and Gatwick airports, and significant but lesser effect to Stansted airport. We also find significant congestion spillover effects from Heathrow to the spatially more distant Manchester and Birmingham airports, showing the extensive spatial impact of Heathrow's development constraints. For European air traffic, controlling for low-cost air carrier growth, only two airports show significant congestion spillover effects: Gatwick and London City Airports. Illustrating that low-cost carriers do not operate from Heathrow, so its limitations cannot affect the predominant low-cost air traffic in other airports. The novel methodology we present in this paper can be applied to congestion research in general to assess regional and modal spills within networks
Il tessuto sociale
No full textIn questo capitolo dedicato al tessuto sociale si individuano i cambiamenti che hanno maggiormente interessato la società bergamasca negli ultimi decenni. A tal fine, si riflette su alcune tendenze in atto e si circoscrivono gli aspetti che appaiono più rilevanti, quali le trasformazioni della famiglia, il suo rapporto con il mondo economico ed imprenditoriale nonché il ruolo che l’associazionismo assume sul territorio. Le riflessioni riportate si basano su una serie di informazioni e dati ricavati da indagini realizzate negli ultimi anni da enti e istituzioni del territorio, finalizzate all’approfondimento dei nodi critici caratterizzanti la provincia di Bergamo. La ricostruzione del quadro presentato ha beneficiato, inoltre, di alcune testimonianze raccolte tramite una serie di interviste in profondità rivolte a “testimoni privilegiati
Connectivity of the European airport network: “self-help hubbing” and business implications
No full textThis paper investigates the connectivity of the European air transportation network. A time-dependent minimum path approach is employed to calculate the minimum travel time between each pair of airports in the network, inclusive of flight times and waiting times. The connectivity offered by each alliance’s network is compared with that of the overall network. The results show that roughly two-thirds of the fastest indirect connections are not operated by the alliance system; this could be exploited to enable a new passenger strategy of ‘‘self-help hubbing’’
