Traffic Distribution Rules in the Milan Airport System Effects and Policy Implications
No full textThis policy note aims to evaluate the effects of the traffic distribution rules introduced in the Milan airport system in 2000, whose objective was to steer traffic from Linate to Malpensa. However, Linate continued operating to the major European destinations, overlapping with the Malpensa network and limiting its performance. That, among other factors, led Alitalia to withdraw its hubbing activities from the airport in 2008. Limitations in Linate and high access times to Malpensa induced low-cost carriers to develop elsewhere. Policy makers should be aware that traffic distribution rules may have unintended consequences and can result in significant economic losses
Connectivity in air transport networks: models, measures and applications
Full text linkThe paper aims to analyze the different connectivity models employed to measure hub connectivity and airport accessibility. They are classified in terms of considered variables, underlying models and obtained results. We compute eight different measures of hub connectivity and airport accessibility for all the European airports. The results show the similarities and differences among the measures. With respect to the correlation to the traditional measures of airport size, small airports may have high accessibility if they have just a few flights to well-connected airports. On the other hand, big airports do not necessarily have a proportionally high hub connectivity since it requires very intense temporal coordination of flights that can be obtained only by large hub carriers with efficient wave-system structures
Connectivity in Air Transport Networks An Assessment of Models and Applications
No full textThis paper classifies and compares eight different connectivity models employed in air transport literature and applies them to European airports. Traditional size-based measures tend to underestimate the accessibility of small airports and overestimate the centrality of large airports. Small airports may have high accessibility levels if they have a few flights to well-connected hub airports. The correlation between the measures is much higher for larger airports than for smaller ones. At lower levels of analysis, the choice of the connectivity measure substantially influences the results obtained. We have identified the criteria that must be considered when choosing a connectivity measure
Congestion spill effects of Heathrow and Frankfurt airports on connection traffic in European and Gulf hub airports
No full textWe develop two stage fixed-effects single-spill and double-spill models for congestion connection spills of London Heathrow and Frankfurt airports on 9 hub airports in Europe and the Gulf. Our panel data covers connection traffic from 1997 to 2013 for Heathrow and 1997 to 2011 for Frankfurt. The single-spill results support strongly that the connection spills from Heathrow's capacity limitations do strengthen competing hub airports of major alliance groups and to a lesser degree one Gulf hub. The double-spill model for Heathrow and Frankfurt shows nearly asymmetric overall spill characteristics between the two airports. Our results underline the influence of airline network strategies on congestion spills as European airline networks are shaped by alliances and umbrella mergers. Thus, the airline network perspective in airport capacity expansion decisions needs to play a greater role, as indicated by our asymmetric results for overall spill effects between Heathrow and Frankfurt airports
Traffic distribution rules in the Milan airport system: effects and policy implications
No full textThis policy note aims to evaluate the effects of the traffic distribution rules introduced in the Milan
airport system in 2000, whose objective was to steer traffic from Linate to Malpensa. However,
Linate continued operating to the major European destinations, overlapping with Malpensa network
and limiting its performance. That, among other factors, led Alitalia to withdraw its hubbing
activities from the airport in 2008. Limitations in Linate and high access times to Malpensa induced
low-cost carriers to develop elsewhere. Policy makers should be aware that traffic distribution rules
may have unintended consequences and can result in significant economic losses
La «Struttura finanziaria ottima» Indotta dalla dual income tax
No full textRecently, most European governments have attempted to reform corporate tax rules in order to favour equity financing over debt. In Italy, in particular, since 1998, the corporate tax system has deeply changed, thank to the introduction of the so-called «Visco reform ». The reform innovations are an interesting experiment of a corporate taxation oriented to equity financing. The main objective of the legislator introducing the two-rate system called Dual Income Tax System (DIT) is to encourage the capitalisation of firms. The aim of this paper is to analyse «the optimal capital structure» which maximizes the net income of firms under different tax systems. Our model shows that two-rate systems are more neutral than one-rate systems such as the tax system existing before the Visco's reform and that prospected by Tremonti, the latter Minister of Finance
