This study attempted to analyze the effect of regulation and political stability in allocation of mobile telecommunication investments in the African continent between year 2001 and 2011. In order to better understand the dynamics of investment in telecommunications, a framework was developed to...

We analyze firms incentives to bundle and tie in the telecommunications industry. As a first step, we develop a discrete-choice demand model where firms sell products that may combine several services in bundles, and consumers choose assortments of different types of products available from...

We study the impact of the access charges of copper and fiber unbundling on an incumbent's incentives to invest in fiber access networks. Once the fiber deployment is in place, the incumbent and the entrant compete for consumers in both copper and fiber markets. We show that when the regulator...

This paper is based on expert discussions on how airport capacity could be improved to benefit the users of aviation, without building new airport infrastructure. These discussions took place at a Roundtable meeting of 34 experts held in Querétaro, Mexico in March 2017. Roundtable participants...

Air traffic numbers have been steadily increasing and are projected to so in the future. Most traffic growth pertains to a small fraction of the total available airport capacity worldwide; particularly the main airport hubs present these trends. As a consequence, they are becoming increasingly...

Since the mid 90's, public transport patronage in Île-de-France (the Paris region) has increased substantially: over the last decade alone a 20% growth was observed. This growth, even though it was an aim of the Sustainable Urban Mobility plan adopted in 2000, was not completely anticipated....

Many major airports are hubs for network carriers at the same time as serving a large local market. The complementarity between these functions is often seen as a prerequisite for viable hub operations, suggesting that spreading the hub network over multiple airports can be very costly and...

Expanding airports is a topic which can easily make it to the first page of the national press. But this is highly unlikely as "bad news" is "good news" and most often failures and scandals make it to the front page. Berlin airport or the on-going failure to open up a nearly-complete new airport...

Like most large cities, Sydney has an airport problem. Demand is increasing faster than supply, and additional capacity will be needed if costly rationing, and delays, are to be avoided. However, compared to many cities, the problems facing Sydney are modest. At the moment, demand is only just...
